304 MEMOIRS ON THE COLEOPTERA 



preceding, the head more densely and strongly punctured and with 

 trace of the frontal impunctate line; antennae more developed, slender 

 but rather more thickened basally, somewhat longer than the body, 

 feebly spinose, the third joint but very little longer than the fourth 

 and distinctly shorter than the first; prothorax smaller, slightly 

 shorter than wide, broadly and evenly rounded at the sides, feebly 

 constricted just before the base, which is as wide as the apex, finely, 

 very densely and evenly punctate, the smooth spot behind the centre 

 rather broadly oval and defined by coarser punctures; pubescence 

 more diffused than in defectus, the sublateral and subentire vittae 

 broad and very feebly defined; elytra three times as long as wide 

 and two-fifths wider than the prothorax, slightly narrowing from 

 base to apex, the punctures strong and rather close, smaller but 

 distinct apically, the pale decumbent hairs numerous, feebly nu- 

 cleated and tending to form a few very irregular longitudinal vittae; 

 fifth ventral as long as the fourth, rounded at the apex, gradually 

 becoming transverse medially. Length (c?) n.S mm.; width 2.6 



mm. Texas molliculus n. sp. 



Form not quite so slender, parallel, dark piceous-brown, the antennae 

 paler; head strongly, closely punctate, with a finely impressed stria 

 throughout; antennae nearly as in the preceding and somewhat 

 longer than the body, except that the third joint is barely visibly 

 longer than the fourth or shorter than the first; prothorax about 

 as long as wide, parallel, with very evenly and moderately arcuate 

 sides throughout, the basal constriction very feeble, the surface 

 differently sculptured, dull, even, with rather large shallow close-set 

 punctures and smaller close punctures filling the interspaces, the 

 impunctate line behind the centre very narrow; pale pubescence 

 rather coarse and abundant, unevenly diffused, the sublateral vittae 

 broad, irregular, loose and not defined; scutellum very densely 

 punctate, semicircular; elytra parallel or very nearly, rather more 

 than three times as long as wide, not over a fourth wider than the 

 prothorax, strongly, not densely punctate, scarcely at all more 

 finely apically, the irregular pale hairs tending to form three broad 

 lines on each, separated by fine subtumid impunctate lines; fifth 

 ventral abruptly and rectilinearly truncate at apex. Length (cf) 

 13.5 mm.; width 2.9 mm. Iowa (Keokuk) parallelus Newm. 



Extermis will scarcely prove to be the same as neglectus Lee., 

 though the size is about the same; the prothorax in cxternus is 

 similar to that of incertus and not shorter; the form is more slender 

 than in incertus, the antennae notably more slender, but the outer 

 apical spines of the elytra are similarly aciculate and not denti- 

 form. My nine examples of villosus, three males and six females, 

 from Texas, Iowa (Keokuk) and several parts of New England 

 differ in such a way as to indicate a mixture of what may be sub- 

 species or perhaps higher forms.* With the male type of medialis 



* The prothorax normally is very nearly as long as wide, but one female example 

 has this somite fully two-fifths wider than long.
