(Lemien, Berlinhafen), differ in some respects from HALE'S specimens, The size varied from 15.1 mm (male) to 18 mm (female); the ratk? of the anteocular part of the head to the postocular part is expressed in the following formulas: AO:PO: :103:32 (male), 113:34 (female); the lengths of the antennal segments are in the following ratio: 26:62:X:64 (male), 28:69:X:65 (female), 31:70:195:64 (female); on two of the specimens the third antennal segments could not be measured due to their curvature. The distance between the first and second coxae is to that between the second and third coxae as 40:75 (male) and 46:78 (female); the acetabula are not pitted. The regions of the body bear the following relation to each other: Head:pronotum: metanotum-.abdomen: :144:61:64:197 (male) and 157:73:69:255 (female). The white median longitudinal line on pronotum is absent although the lateral ones are very conspicuous. Dr. HALE says his species „evidently has some affinity with H. papuana KIRK. but the male of that species is of larger size with the under side blackish'. KIRKALDY'S species came from Fly River in New Guinea which is in that portion of the Island nearest to Cape York, Australia. The type of H. papuana KIRK. has been destroyed and the description is inadequate. The slight difference in size and color of the ventral side of the abdomen is surely not sufficient to distinguish H. papuana KIRK. from H. hoplogastra HALE. Since the specimens before us labeled „N. Guinea BIRO 96, Lemien, Berlinhafen" from the Hungarian Museum are certainly HALE'S species, even though they show some AARIATION, there is grave doubt concerning the specific differences of the two species. Dr. KIRKALDY had a male specimen, yet he failed to mention the large conspicuous processes on the venter of the sixth abdominal segment. His type specimen was carded which fact, with the dark abdomen as a background, may account for this oversight. This question cannot be settled without the examination of more material. We also have before us specimens of this species from the U. S. National Musem labeled „Gordenvale N. Q." Hydrometra Hutchinsoni* sp. n. (Plate III). Size and Color. Length, 13 mm (holotype); the general color is brown, connexiva and sides of abdomen nearly black, the abdominal tergites dark brown and polished except the last one; a pale lemon streak on the venter of the thorax and head beneath and behind the eyes.
