This species can be separated from the majority of Coccophagus 

 species by the completely black body, hyaline wings, and three pairs 

 of bristles on the scutellum. It is most likely to be confused with 

 C. atratus Comj)ere and G. timberlakei^ new species. The Rust col- 

 lection includes a good series of G. anthracinus of both sexes. The 

 supposed male of this species was described from two specimens 

 collected in a breeding cage in association with female G. anthracinus 

 with which they were attempting to mate. These males are not in 

 agreement with the males associated with G. anthracinus in the Rust 

 collection. Since it has been observed that male Goccophagus of 

 one species often attempt to mate with females of a different species, 

 it is not safe to conclude that the two sexes are correctly associated 

 just because of their intimate contact. It is more likely that Rust's 

 specimens are correctly associated and that the male previously de- 

 scribed as G. anthracinus is another species. 



Female. — Body usually entirely black to dark brown in parts, in 

 certain lights with metallic reflections. Coloration of the head 

 variable; light colored variants with the face, cheeks, and antennae 

 yellow or orange with occasional traces of fuscous ; at the other ex- 

 treme these parts may be entirely black or dark brown. Frontover- 

 tex usually more or less blackish, except the triangular dorso-lateral 

 angles, occipital margin, and ocellar lines which are orange or yel- 

 low. Legs predominantly black to brown with pale markings as 

 follows : apices of all femora, the tibiae with variations ranging from 

 pallid with a faint suffusion of brownish to predominantly brown 

 with only the apices rather broadly pallid. Tarsi usually pallid, 

 the apical joints dusky. Generally the hind tibiae are plainly 

 darker than the fore and middle tibiae. 



Pedicel not quite one and one-third times as long as wide and 

 plainly shorter than the first funicle joint. First funicle joint long- 

 est, not quite one and one-half times so long as wide; second and 

 third subequal in length, each slightly shorter than the first; all 

 almost imperceptibly increase in width distad so that the third is 

 almost as wide as long. First club joint a trifle longer and wider
