a various number of days; then the last abdominal sterna or sometimes all the abdomen was removed and the male genitalia were extracted under a stereoscopic binocular (Galileo, Milano).Very often the abdomen underwent a short boiling in diluted alkali (10 % KOH solution) in order to have all not cuticular parts destroyed and removed. The male genitalia (or better the phallus) once isolated were throughly washed with destiled water and let to dry up. Only in one case (Stictoderia subseriata

) the transparence of the phallus has advised to make microscopic préparâtes. In this case, after treatment with weak alkali, followed by washing in destiled water and drying up, the piece was transferred in glacial acetic acid for dehydration, then in terpinol for diaphanization and finally mounted in Canada balsam. All drawings have been made using a "camera lucida" of the ABBE-APATHY model (Koristka, Milano), with direct illumination. The original drawing have been made by Miss MARINIA-CE

LINA DAL MASO during the preparation of her thesis for the Doctor degree (Nat. Sciences), then the drawings have been inked by Mr.RENZO MAZZARO, technician in the Institute in which the research has been carried out. All the drawings have been made at the heigth of the stage of the microscope in order to calculate directly the exact enlargment, knowing the enlargment of oculars and objectives used for each drawing. The drawings in which lighted and shadowy parts are visible have been done by the author and inked by Mr. CLAUDIO FRISO, technician of the Institute, to whom I am much indebted. It is a pleasure for me to thank here particularly Dr. Z.

KASZAB, Director of the Hungarian Natural History Museum, Budapest, for all the help and advice he gave me since many years, and for having accepted the present paper for publication. I should mention also a visit to that Museum in which I found the greatest liberality, since I was allowed to examine all the Tenebrionid materials and choose all the species and specimens I wished to bring with me for study. A part of the material has been already published in Annls hist. - nat. Mus.natn. hung.

, 68, 1976: 117-140. DESCRIPTION OF EXAMINED MATERIAL Tentyriinae - Epitragini Epitragus emarginatus Champion, 1884 (Fig. 1) CHAMPION (1884): Biológia cent.-am., 4 (1): 24. Examined specimen: Los Encontrados, Maracaibo basin, near Rio Onia, leg.

L.CROIZAT. Basale well separate from apicale, both of similar length (A:B = 1,0). Basale only slightly broader than apicale, with almost parallel sides, though not uniformly. Apicale restricted a little after the base, then slightly widened up distal 2/3, to restrict itself again up to apex; this is only scarcely pointed. The tip is furnished with several setae of different length and disposed somewhat irregularly. Lateral view: basale very flattened, only scarcely thicker towards the apex, apicale regularly bent dorsally, wide at the base, then rather thin up to the apex. This is apparently scarcely pointed and furnished on dorsal side with some setae. Aedeagus a little longer than apicale, gradually narrower towards apex, which is bent dorsally and quite pointed. Epitragus roscidus Erichson, 1848 (Fig. 2) ERICHSON (1848): Schomburgks Reise in British-Guiana, Leipzig, Weber, 3: 565. Examined specimen: Maiquetia, near Caracas, D.F., 1948, leg.G. MARCUZZI. Highly characteristic because of apparent lack of aedeagus. Basale scarcely longer than apicale (A:B = 0,91), with parallel sides, apicale a little sinuate at the base, then gradually narrowed up to the apex, which is sharply pointed, lanceolate. In lateral view convex dorsally, both basale and still more apicale. Thickness of basale very uniform, that of apicale decreasing gradually and regularly from base to apex, which is a little bent ventrally and sharply pointed.Slightly sclerotized, rather transparent, relatively small compared with body size (1,66 mm long). Epitragopsis parumpunctatus (Fairmaire, 1892) (Fig. 3) FAIRMAIRE (1892): Annls Soc. ent. Fr., 61: 78 (Epitragus). Examined specimen: Aguas Negras, D.F. Venezuela.
