CAMPOPLEX Grav. 



A.reolet of the wiugs complete (in all the species examined rhomboidal, the lower 

 angle obtuse). 



Metathorax in the middle longitudinally concave or subsulcate. 



28. Campoplex vitticollis, Harris's Cat. 9- Length 0. GO in. Br. wings 0.80 in- 

 5 . Ferruginous, with a black stripe on thorax. Antennaj moderate, ferruginous 



at tip and base, eyes scarcely contracted below, head black; mandibles, palpi 

 and tegulse yellow; tips of mandibles dark; face and thorax covered with silvery 

 hair; a black line, interrupted by scutel, from the head to base of metathorax? 

 scutel rufous at apex; a line on 2nd segment of abdomen, valves of terebra and 

 the pectus black; anterior legs, tips of intermediate femora and legs below and 

 base of posterior tibire yellow; a line on anterior femora above, intermediate coxpe, 

 trochanters and femora, posterior coxfe, trochanters, base of femora beneath and 

 tarsi black; four posterior coxis above, femora and apex of tibiae ferruginous; 

 wings yellow hyaline, nervures dark. 



Four specimens. Ct., and Md. (P. R. Uhler). 



In this and all the succeeding species the thorax is closely punctured, 

 except beneath the wings, where there is a small space more or less smooth 

 or striate. The punctures are most coarse on the metathorax, sometimes 

 appearing more like granulations than pits. The punctuation of the pleura 

 is rather sparse and the color generally dull. In this species it is shining. 



29. Campoplex villosus, n. sp. ^ %. Length 0.64 in. Br. wings 0.76 in. 



9 % . Black, with the metathorax and abdomen ferruginous. Antennae long, pi- 

 ceous beneath, jDroduced to a slender tip; a thin longitudinal ridge between ocelli 

 and antennae; head and thorax covered with silvery hair, longest on face and 

 metathorax; a spot on mandibles, palpi and tegulse yellow; a triangle below in- 

 ferior wings, metathorax, except at summit, posterior coxae above and 1st segment 

 of abdomen ruby-red ; remainder of abdomen ferruginous, a black line on second 

 segment; a spot on anterior coxae, the four anterior legs and posterior tibiae in the 

 middle yellow: a line on anterior femora above, intermediate coxae and most part 

 of femora and posterior legs black; basin of metathorax transversely striate, the 

 angles distinct, the ridge between them and the postscutel forming a carina, ang- 

 ulate or bent, above which are smooth shining spaces; wings hyaline. 



Four specimens. Albany, N. Y., and Ct. 



The pleura is covered with very fine punctures and shines like the ab- 

 domen. The carinae on the summit of the metathorax appear in most 

 species of Camjxjplex. 



30. Campoplex argenteus, n. sp. 9. Length 0.64: in. Br. wings 0.94 in. 



9. Black, with abdomen rufous, except at base. Antenme a little more than 

 half the length of body, flagellum dark piceous, }>asal joint yellow beneath (in 

 some cases piceous or black), lower half of face and most of thorax covered with 

 silvery white hair; basin above antennae distinct, not rough, face below antennae 

 coarsely punctured; mandibles (except tijis), palpi and tegulrc yellow; basin of 

 metathorax transversely wrinkled below, striate above and shining at summit;
