4. Culicoides guttifer deMeijere, var. histrio View in CoL , new variety (fig. 1, h).
Male and female: dark brown, including legs and halteres; immediately above and below the knees slightly paler. The mesonotum cinereous with subshining black markings as follows: a pair of narrow vittae anteriorly (in some cases contiguous) between the sgining humeral pits; a pair of elongate oval spots in the prescutellar depression, a broader pair of elongate lateral vittae behind the humeral pits, a transverse spot covering and in front of the scutellar suture, and a more or less elongate oval area in front of each wing base. These marks resemble somewhat those of C. crepusrnlaris Malloch (1915) but the median lines have parallel sides. The extent of these marks seem subject to some variation and in some cases are more brownish. The hypopygium resembles that of C. copiosits Root and Hoffman (Am. Jour. Hygiene 25: 17, 1937) rather closely, including claspers, aedeagus, and apico-lateral processes of the tergite, but the inner processes (so-called harpes) are less tapering (fig. 1, h) and not so attenuated apically. Wings with about 16 round hyaline areas on a gray background, those at the base of the wing more or less diffuse. The elongate dark stigma! spot covers the distal half of the first and all of the second anterior radial cell. The large hyaline area covering the crossvein encroaches on the basal half of the first radial cell. The venation and the wing markings are like those of C. gitttifer deMeijere as shown by Edwards (Bull. Ent. Res. 13: 169, fig. 2, 1921). Length 1.25 mm., wing, measured from the humeral crossvein, 1 mm.
