This is :i lar^e and rare species, (listiiisnishable without diffi- 
culty by the color and structure of the antennae, as well as by 
pronotal and gcnitalic characters. It is most distinctly a west- 
ern si^ecies and I feel certain that the Massachusetts example, 
doubtfully recorded above, has l:een mislal)elcd. In one f)f her 
Mt. Washington lists iMrs. Slosson'* records dcbilis, but the speci- 
men proves on examination to have been misidentihed.

Distrihtdion. — Al.\k.\ma (t'. P. Baker). 
Description . — Blackish brown; second antennal segment with sjiarse 
yellow dots, third whitish yellow except in basal third; lateral and basal 
portions of pronotum yellow, the median carinae j)osteriorly either black or 
yellow; ai)ical half of scutellum, sometimes only at sides, i)ale brown, the 
extreme ai)ex black; corium, connexivum, and ventral surface mottled with 
yellow; apical angles and more or less of apical margins ol connexival segments 
yellowish; legs dark, with yellow dots, trochanters and ajiices ot tibiae ])ale; 
membrane grayish, vagviely maculated. 
Head as long as broatl, a little longer than ])ronotum (2.5 to 23); tylus 
rather short, sides i)ara)lel; im])ressions of vertex deep, widely sci)arated, 
slightly divergent anteriorly, connected posteriorly; vertex with two ])arallel 
rows of coarse granules; preocular tubercles distinct, rather acute; eyes 
prominent, substylated; antenniferous spines very acute, conical, moderately 
divergent, with distinct lateral tooth; ])ostocvdar tubercles distinct, acute or 
obtuse; antennae (tig. 27e) short and slender, not as long as head and ])rono- 
tum together (40 to 4<S), the first segment reaching about to middle of tylus, 
length of second a little less than width of head including one eye (10 to 21); 
rostrum extending about to middle of mesosternum. Pronotum (fig. 27d) 
with lateral margins rather broadly exjilanate but scarcely reflexed, variably 
crenulate and with a few remote, blunt teeth; disc with a decided transverse 
elevation anteriorly, on which the intermediate carinae terminate each in a 
tubercle; carinae well elevated. Scutellum slightly longer than ])ronotum 
(20 to 23), broad, sides slightly raised, sinuate, parallel in basal third, straight 
toward the very broad aj)ex; basal half a little elevated, with a narrow, 
median, tuberculiform extension. Hemielytra (cf ) rather stnmgly narrowed, 
exjiosing disc of abdomen at sides, reaching genital lobes, corium to apex of 
fourth segment; (9) similarly narrowed, reaching about to middle of sixth 
segment, corium about to middle of fourth; basal expansion of exocorium 
rather narrow; mesocorium with two, endocorium without distinct trans- 
verse veins. Abdomen broadly oval; the lateral margins with distinct 
subangidar i:)rominence before apex of each segment. 
cf (tig. 27b). Fifth ventral segment shorter than sixth (10 to 13); genital 
segment short, strongly convex, the lobes very short. Length, 5.8 to 6 mm.
