extending: over anterior fourth of inesosternuin. I’ronotuin (fig;, did) rather 
flat, lateral margins not rcflexed, the teeth eom|)aratively even, hut valu- 
able, often much smaller and more numerous than in the figure; carinae 
moderately elevated, the median pair nearly iiarallel in the male or moder- 
ately convergent at nuddle in the female. Scutellum longer than pronotuni 
(3.U to 25), triangular, sides straight or slightly curved from near base to 
narrow ai)ex, slightly elevated; disc with low rounded ])rominence before 
middle, two depressions at base. Ilemielytra (d') broad, exposing scarcely 
more than the connexivum, reaching middle of genital lobes, corium beyond 
middle of fourth segment; (9) much more narrowed toward apex, reaching 
to nuddle of sixth segment, corium to base of fourth; exocorium moilerately 
exiianded at base; entire corium with numerous more or less distinct trans- 
verse veins. 
d (fig. 31b). Fifth ventral segment distinctly shorter than sixth, its 
apical margin l)roadly transverse and almost straight across middle; genital 
segment short, strongly convex, carinate; ab<tomen broadly oval, crenate. 
Length, 0.8 mm. 
9 (fig. 31a). Dorsal genital segment more than one-half as long as broad 
(18 to 30), the jmsterior margin variably emarginate at middle, straight, 
obli(|ue laterally; alxlomen elongate, oval, lateral margins notched. Length, 
8 to 8.8 mm.

This species, closely related to situ ills and to acutus, is to he 
distinguished Ity the color, antennal structure, and genital char- 
acteristics. The pronotal teeth are usually rather small and 
even, luit they exhiltit considerable variation, with intermediates 
which are often asymmetrical, between the extremes. A male 
specimen from (Ireensburg, Pennsylvania, included l)y Heide- 
mann in the type series, is an obscurely marked example of 
acutus, identical with another having the same data, whi(‘h 
Heidemann placed with his acutus series. There are several 
specimens of shennani in collections, determined l)y Van Duzee 
as simiiis variety centriguttatus.
