ART. 7 REVISION OF COGCOPHAGUS COMPERE 49 



small size and predominantly yellow coloration are at once dis- 

 tinguished from the other small yellow species by the antennae, 

 which in this group have the pedicel smaller than the first funicle 

 joint and the funicle joints decrease in length and slightly increase 

 in width distad. 



Female. — General color yellow; lateral and ventral parts of the 

 thorax and the face and cheeks pale. Pronotum mostly blackish. 

 Anterior margin of mesoscutum on meson more or less suffused with 

 blackish. Sutures of scutellum and axillae anteriorly and the meso- 

 scutum posteriorly vaguely suffused with blackish. Abdomen with 

 five rather obscure dusky cross stripes, the first five tergites dusky 

 on basal half. Eyes and ocelli reddish. Mandibles mostly brown. 

 Fore tarsi entirely slightly brownish, and tarsi of other legs dusky 

 apically; remainder of legs yellowish. Antennae yellow with 

 brownish sensoria. 



None of the antennae show the scape and pedicel clearly. Ap- 

 parently the pedicel is about one and one-third times as long as wide 

 and slightly shorter than the first funicle joint. First funicle joint 

 plainly the longest, somewhat more than one and one-third times 

 as long as wide ; second and third successively slightly decreasing in 

 length and slightly increasing in width. Club large, basal joint 

 plainly larger than the third funicle joint; second as wide as the 

 first and slightly shorter; third much the smallest (fig. 35). 



Mandibles as shown in Figure 177. 



Mesopleura prominent, bulged outward. Scutellum wider than 

 long but not strongly transverse (11:8) and not quite as long as 

 the mesoscutum (8:10). Abdomen not quite as long as the thorax, 

 broadly rounded at apex ; ovipositor as seen through the derm short, 

 very slightly exerted beyond apex. Spiracles reniform. Median 

 piece of metanotum well developed (fig. 142). 



Fore wings hyaline, rather finely and densely ciliated; the basal 

 posterior hairless streak bent upward at its distal end. Submar- 

 ginal vein distinctly longer than the marginal; stigmal about as 

 shown in Figure 88. Marginal fringe moderately short. 



Mesoscutum moderately densely setose, setae along the sides and 

 posterior margin slightly stronger than elsewhere. Scutellum with 

 three pairs of strong bristles. Each parapsis with three setae and 

 each axilla with two. The setae somewhat darker than the derm 

 but not strongly contrasting. 



Basitarsus of middle legs almost as long as the succeeding four 

 joints united; tarsi moderately short and furnished with numerous 

 peg-shaped spines; tibial spur slightly shorter than the basitarsus. 

 Paired spurs at apex of hind tibiae very unequal.
