SUBFAMILY II. — CAPSIN^E. 747 



England west to British Columbia and southwest to New Jer- 

 sey. Recorded also, probably in error, from Texas. Occurs on 

 grasses, nettles, etc. 



XII. Horcias Distant, 1884, 277. 



Rather large oblong or oblong-oval glabrous shining species 

 having the head wider across the eyes than long, its front 

 strongly declivent ; eyes large, prominent, contiguous to front 

 margin of pronotum; joint 1 of antennae stout, about as long 

 as head, 2 twice as long as 1, or slightly more, gradually feebly 

 thickened from base to apex, 3 and 4 much more slender, sub- 

 equal in length; beak reaching or surpassing middle coxae; 

 pronotum trapezoidal, twice as wide at base as long, collar dis- 

 tinct, calli not prominent, basal portion convex and declivent 

 forward, its surface usually almost smooth or with fine im- 

 pressed points; scutellum nearly equilateral, slightly convex; 

 elytra entire, cuneus and membrane deflexed ; joints 1 and 2 of 

 hind tarsi subequal, 3 slightly shorter than the other two 

 united. 



The species of this genus are extremely variable in color, no 

 fewer than 14 color varieties of our common species, H. dis- 

 locatus Say, having been named. Distant (loc. cit.) described 

 11 new species from Central America, basing them mainly upon 

 color characters alone. Two species are recognized from the 

 eastern states. 



KEY TO EASTERN SPECIES OF HORCIAS. S1 



a. Form oblong-oval ; color extremely variable, but never shining black 

 with scutellum wholly yellow; beak reaching hind coxae. 



769. DISLOCATUS. 



act. Form oblong, subparallel; color shining black, the scutellum usually 

 yellow; beak reaching middle coxa?. 770. fallax. 



769 (1000). Horcias dislocatus (Say), 1832, 21; I, 339. 



Oblong-oval. Tylus, upper half of cheeks, base of vertex, two oblong 

 or subquadrate spots on basal half of pronotum, scutellum except a nar- 

 row median line, inner half of clavus and an oblique stripe on corium, 

 black; membrane and apex of cuneus piceous; remainder of upper sur- 

 face reddish or (var. uffinis Reut.) dull yellow; under surface piceous 

 with a pale line on meso- and metasterna; legs and prosternum yellow, 



81 Uhler (1894, 263) described Pcetilocapsus marmoratus from Lower California 

 and mentioned "fragments of specimens from Texas and Maryland" as being in his 

 collection, "but not in condition for identification." Van Duzee, in his Catalogue, 

 places it under Horcias as Xo L003. It is described as being pale yellow irrorated 

 and marbled with brown, with two round brown dots behind calli of pronotum ; length 

 4.3 — 5 mm. As no eastern record other than that of Uhler can be found, it is not 

 farther considered in this work.
