ChcBtotaxy.—Second segment without marginal bristles or, if present, short, decumbent and inconspicuous; third with two, sometimes very weak; fourth with complete marginal row. Genital Segments.—Both dull orange except that first is darkened anteriorly. First much the larger, marginal bristles absent: second, flattened, vestiture shorter than that of first; anal area small. Forceps slender, abruptly curved. Fig. 22.—Metoposarcophaga spp., male genitalia. (Page 157.) at right angles to the basal portion, distal end slightly enlarged with a short tooth directed forward; forceps in profile view except tip concealed by accessory plate. Penis and accessory parts almost identical with those of M. mcurva Aldrich. Described from nine male specimens. Range.—BnX\s\\ Columbia; Savary Island, July 13, 18, 20, 31, 1917, (R. S. Sherman, collector). Holotype taken in same locality and by same collector on July 18, 1917. The writer has two females which are obviously either M. incurva or M. tothilli and though the posterior tibia is shorter than the tarsus, it is not as short as in the males of these species nor does it present the peculiar structural modi- fications found in M.
