broadly arcuate, nearly truncate, not bisinuate; with a strongly developed, 

 acute, basal, transverse carina towards the sides; the side margin produced, sub- 

 acute from the- hind angle forward for tAvo-thirds the length, excavated on the 

 under side below the subacute margin; the disc only moderately convex, closel}' 

 finely punctured and densely granulate or finely rugulose, the granulations 

 pointing chiefly towards the meson which is a fine raised line; densely clothed 

 with red pubescence of two lengths, long erect hairs increasing in length from 

 base to apex and beneath these a vestiture of very short suberect bristles. The 

 scutellum is circular, extremely minute and not depressed. 



The elytra have the base only slightly arcuate, not serrate; the sides sub- 

 parallel, slightly arcuate for two-thirds of the length, then gradually arcuate to 

 the narrowly rounded apex; rather narrowly rounded behind as viewed from 

 above; the declivity steep; the strise very finely and not strongly impressed, 

 almost obsolete near the base, gradually stronger to the declivity where they are 

 moderately but finely impressed; the last stria deeply impressed about the side 

 of the declivity; the sutural striae together with the sutural interspaces markedly 

 impressed towards the base; the strial punctures small on the disc and declivity, 

 very small on the sides; the interspaces wide and flat becoming gradually 

 m^oderately convex upon the declivity; the interspaces closely indistinctly 

 punctured and very densely and coarsely granulate, except upon the declivity 

 which has the interspaces densely, minutely punctured, not granulate, and uni- 

 seriately finely tuberculate; the sutural interspaces much narrowed towards 

 the base; rather densely clothed with lo"ng red hairs and finer pubescence; the 

 uniseriate hairs of each interspace numerous, long and erect, extending from 

 base to apex; the remaining pubescence rather long and erect towards the base 

 becoming shorter behind, and minute and somewhat scale-like upon the declivity. 



The veiitral surface rather closely and rather finely punctured and moderately 

 hairy; the venter of the prothorax very densely granulate-punctate; the first 

 and fifth visible abdominal segments longest, the second little shorter than the 

 first and hardlj' as long as the next two combined ; the mesosternum moderately 

 protuberant; the third tarsal segments moderately widened and deeply bilobed; 

 the presternum deeply excavated with the ridges acute; the legs black, the tibiae 

 very wide and very coarsely toothed. 



We have two specimens from Clouderoft, N.M., obtained through the 

 kindness of Mr. W. Knaus. A third specimen from the Cornell collection 

 "S. Fe Canon, N.M., 7,000 ft., Aug., 1880 (Snow)", is evidently the same 

 species but has the long hairs somewhat shorter than in the type and the 

 declivity more noticeably scaly. It is possibly the male. We have also seen 

 specimens from California. 



Hylastes scaber, n. sp. 



Allied to porcuJus Er. but much more coarsely punctured, with the el3'tral 

 striae more strongly impressed, and the interspaces rugose; distinctl}' more 

 slender than in salebrosus Eichh., with wide striae, not so deepty impressed, less 

 coarsely rugose interspaces, pronotum more coarsely punctured and straight on 

 the sides behind, and with moderately toothed tibiae. Length, 4 mm.; width, 

 1-4 mm. 



The head has the front rather coarsely, very closely, roughly punctured; 

 the transverse impression moderate; the epistoma broadly impressed on each 

 side, with the median carina well developed and reaching to the transverse 

 impression. 



The projiotum is but little longer than wide, moderately but distinctly 

 narrower than the elytra, the hind angles rounded, the sides parallel, nearly 

 straight to beyond the middle, then constricted, moderately bisinuate, and 

 broadly rounded on the front margin; the disc extremely coarsely and not very
