ART. 7 REVISION OF COCCOPHAGUS COMPEEE 37 



gin of mesoscutum, propodeum, proepisterna, ventral part of pre- 

 pectus, mesosternum, and mesoepisterna varying from blackish to 

 brownish. Median part of metanotum pale yellow. Axillae 

 slightly brownish. Tegulae spotted with fuscous. Eyes and ocelli 

 vermilion. Wing veins pale yellow. Abdomen black to brown- 

 ish. Legs pale yellow except for the middle and hind coxae which 

 are more or less suffused with blackish. 



The antennae offer the best character for the recognition of this 

 species. The funicle joints are articulated ventrally and the ventral 

 part of each joint is produced further distad than the dorsal part. 

 The sensoria are characteristic; on each funicle joint, in lateral 

 view, five or more sensoria are visible extending the entire length 

 of the joints on which they occur. In appearance the antennae is 

 not unlike that of a male Prococcophagus. Scape slightly wider 

 than usual, about four times as long as wide. Pedicel one and one- 

 half times as long as wide, slightly but appreciably shorter than the 

 first funicle joint. Funicle joints all subequal, slightly less than 

 one and one-half times as long as wide. Club not markedly dif- 

 ferent from the funicle, hardly any wider and with similar sensoria 

 (fig. 27). 



The two females available for study are poorly mounted and a 

 satisfactory view of the mandibles can not be had. Apparently 

 mandibles sharply tridentate. 



Fore wings hyaline; an oblique hairless streak cut off from the 

 basal hairless streak by three rows of cilia; the oblique hairless 

 streak continuous with the hairless streak beneath the marginal 

 vein. Cilia of disk moderately coarse and sparse. Marginal fringe 

 moderately long. Submarginal vein only a trifle longer than the 

 marginal, the difference hardly appreciable without actual measure- 

 ment. Postmarginal vein distinct, well developed, but not produced 

 so far distad as the stigmal vein; stigmal vein with a slender neck 

 and widely expanded knob (fig. 114). 



Frontovertex with slender, scattered black setae. Mesoscutum 

 with rather sparse, slender, black setae, those arranged along the 

 lateral and posterior margins much longer. Each parapsis with 

 three rather long, slender, black setae. The setae of the axillae are 

 distinctive; anteriorly there are two setae about as long as those on 

 the disk of the mesoscutum and posteriorly a much stronger setae 

 comparable in length to the anterior pair of scutellar bristles. 

 Scutellum with three pairs of long, slender bristles, the anterior pair 

 a trifle closer together than the median and apical pairs that are in 

 longitudinal alignment. The three pairs of scutellar bristles sub- 

 equal in length, the apical pair thickest. Setae on the tergites 

 rather long and slender; on the fifth, sixth, and seventh tergites 

 arranged across the dorsum.
