6 — Form rather stout, polished, black, the rufous elytra with a black basal 
cloud, the legs and antennae pale; head quadrate, as long as wide, the 
sides straight; angles moderately rounded, the neck very wide as usual, 
the punctures coarse, very sparse; antennae long and rather stout, 
much longer than the head and prothorax, feebly incrassate distally, the 
medial joints rather more than twice as long as wide and longer than 
the subapical; prothorax nearly as in longiuscula, a little longer than 
wide, the sides more converging from apex to base, just visibly wider 
than the head, the punctures somewhat coarser and still sparser; elytra 
elongate, parallel, a fourth wider and longer than the prothorax, the 
punctures moderate, impressed, arranged in regular, scarcely impressed 
series, except near apex, where they are finer and confused; abdomen 
but little narrower than the elytra, finely, closely punctulate. Male 
with the fifth and sixth ventrals wholly unmodified on the surface, the 
former with a small shallow and gradually formed median sinus at 
apex, the emargination in the form of a feeble cusp with broadly 
rounded point, the sixth with a very large subcircularly rounded emar- 
gination, occupying the entire apex and fully twice as wide as deep.

Form more slender, the elytra bright red, without a distinct basal cloud, 
the legs pale, the antennae slightly infuscate; head as in soror but 
smaller, the antennae rather thick, scarcely as long as the head and pro- 
thorax, barely at all incrassate distally, the medial joints about two- 
thirds longer than wide and longer than the subapical; prothorax 
rather distinctly elongate, equal in width to the head, slightly narrowed 
posteriorly, the sides nearly straight; basal angles more broadly 
rounded than the apical as usual, the punctures not coarse but deep, 
distinct, irregularly and sparsely distributed, more closely aggregated 
along the median smooth line; elytra parallel, but little longer than 
wide, very slightly longer than the prothorax and about a fifth wider, 
the punctures small and very feebly impressed, arranged serially, 
except toward apex, where they are broadly confused and still smaller; 
abdomen much narrower than the elytra, finely and not very closely 
punctate. Male with the fifth ventral broadly, subconically impressed 
in apical two-thirds, the impression clothed with short coarse black hairs 
extending obliquely outward from the glabrous median line, the apical 
margin sinuate across the end of the impression, the sinus as wide as 
the latter, evenly, circularly rounded and very shallow; sixth with a 
very deep and acutely ogival incisure, twice as deep as wide, the 
notch abruptly formed, with its opening two-fifths as wide as the apex, 
the surface not modified. Length 7.8 mm.; width 1.12 mm. Texas

pale and rufous; antennae ferruginous; head moderate, subquadrate,
