X. ANNALES MüSEI NATIONALIS HUNGARICI. 1912. REVISION OF THE AMERICAN CIMICIDAE. By Dr. G. HORVÁTH. The family of Cimicidae is represented in the New World by 7 species, two of which also inhabit the Old World. -One is the Common Bed-bug (Cimex lectularius) introduced certainly from Europe, the other species in the Tropical Bed-bug (Cimex hemipterus) distributed in the tropical regions of Asia and Africa, whence it was probably imported into America. Two of the 5 native American species (Cimex pilosellus, Oeciacus viearim) are limited to North America, one (Haematosiphon inodorus) occurs in Mexico and the adjacent parts of the United States, while two little known species (Cimex foedus and valdivianus) have been described from South America. The considerable material in the Hungarian National Museum and other collections, principally the very important series of the U. S. National Museum of Washington, communicated to me by the kindness of Mr. OTTO HEIDEMANN , gave me the opportunity of making a careful study of the American Cimicidae. The American species of this family belong to three genera, which are distinguished as follows : 1 (4). Rostrum short, reaching to about the anterior coxae ; scutellum acuminate at the apex ; lateral margin of the elytra not reflexed, apical margin more or less rounded ; intermediate and posterior coxae very remote. 2 (3). Body covered with short hairs, only the lateral sides of pronotum and elytra fringed with longer hairs ; antennae with the third and fourth joints very much thinner than the first and second and capillary J pronotum with the anterior margin very deeply sinuate. Cimex LESN. 3 (2). Body clothed with long silky hairs; third and fourth joints of the antennae only a little thiuner than the first and second and filiform; anterior margin of the pronotum very slightly sinuate or nearly straight in the middle, produced at the lateral angles. Oeciacus STIL. 4 (1). Rostrum long, reaching to the posterior coxae; scutellum rounded at the apex ; lateral margin of the elytra strongly reflexed, apical margin slightly sinuate towards the middle ; intermediate and posterior coxte subcontiguous.
