62 MEMOIRS ON THE COLEOPTERA 



ogival behind; striae deeply impressed suturad, scarcely so laterad, 

 with rather strong and somewhat ununiform punctures, the sixth 

 stria extending three-fifths, the seventh barely traceable as a loose 

 series of very minute punctules; fovese at two-fifths and two-thirds. 

 Length (cf 9 ) 5.7-6.3 mm.; width 2.2-2.4 mm - New Mexico 

 (Jemez Springs and on the road to Fort YVingate) and Colorado. 

 Twelve specimens animatum n. sp. 



Elytra castaneous, ornamented, as in ustnlatum, with a nubilous elongate 

 humeral paler area on each, and a common bioblique subapical fas- 

 cia, which is also nubilously defined. Body moderately stout and 

 convex, polished, piceous-black, with feeble lustre anteriorly, be- 

 neath piceous, the abdomen in great part rufous, the legs flavo-tes- 

 taceous; head rather small, with deep sulci and moderately prom- 

 inent eyes, the antennae long and slender, fusco-testaceous, clearer 

 basally; prothorax large, barely a fifth wider than long, the sides 

 subevenly rounded to the basal angles, which are minutely prom- 

 inent and sharp; margins strongly reflexed basally, very finely near 

 the apex; surface smooth, the anterior impression fine and angular, 

 the posterior large and distinct, the stria between them fine; foveee 

 deep and long, linear, the carina obsolete; elytra nearly two-thirds 

 longer than wide, only one-half wider than the prothorax, parallel, 

 with very feebly arcuate sides, gradually parabolic behind; striae 

 rather deeply impressed suturad, unimpressed laterad, having unu- 

 sually coarse, deep and well separated punctures, the sixth extend- 

 ing three-fifths, the seventh completely wanting; oblique apical part 

 of the fifth stria short and not conspicuous; foveae deep, near two- 

 fifths and two-thirds. Length (c? 9 ) 6.8-7.4 mm.; width 2.75-2.8 

 mm. Colorado and New Mexico (Jemez Springs), .pernotum n. sp. 



29 Body small in size, convex, ventricose, polished, piceous-black, the 

 legs pale rufous; head moderate, with narrow shining sulci and well 

 developed eyes', nearly four-fifths as wide as the prothorax; antennae 

 slender, fuscous, paler basally, three-fourths as long as the elytra, 

 the medial joints between two and three times as long as wide; pro- 

 thorax a third to two-fifths wider than long, the sides strongly 

 rounded, converging basally and becoming parallel for a short dis- 

 tance before the angles, which are right; surface convex, very smooth, 

 with feeble impressions and fine and much abbreviated stria; foveae 

 smooth, small, oval and very deep, close to the rather distinct carina; 

 elytra oblong, two-fifths longer than wide, two-thirds wider than 

 the prothorax, rapidly and obtusely ogival in apical third, the striae 

 unimpressed, consisting of rows of very coarse and widely separated 

 punctures, obsolete in apical third, the eighth consisting of a row of 

 very large deep punctures, notably distant from the margin, feebly 

 impressed, becoming unimpressed basally, the marginal stria also 

 deep and strongly punctured; foveae at apical and before basal third. 

 Length (cT 9 ) 3-35~3-8 mm.; width 1.25-1.4 mm. California (coast 

 regions from San Francisco Bay northward). Thirteen specimens. 



brevistriatum Hayw. 



30 Elytral striae very much abbreviated, extending as a rule barely be- 

 yond the middle, the eighth less widely separated from the margin. .31
