not quite as long as the head and prothorax, third joint about two and one-half 

 times as long as wide, scarcely as long as the next two, fourtli much longer 

 than the fifth. Prothorax nearly one-third wider than long, the apex a very 

 little narrower than tlie base, transversely truncate, the apical angles small 

 but acute, anteriorly prominent, dentiform and feebly everted ; base very 

 feebly, evenly arcuate ; sides strongly, almost evenly arcuate throughout, the 

 basal angles very obtuse, not rounded but not in the least prominent ; disk 

 rather strongly convex throughout, widest just before the middle, somewhat 

 sparsely but deeply and rather coarsely punctate ; side margins very minutely 

 beaded. Elytra about three times as long as the prothorax, and at base, just 

 visibly wider than the base of the latter, gradually acute at apex, inflated, 

 widest in the middle where they are about three-fourths wider than the 

 prothorax ; sides evenly arcuate ; humeri obtuse but not rounded, not at all 

 prominent ; disk confusedly, finely creased, rather coarsely and distinctly 

 granulato-reticulate, very finely and sparsely puuctate, the punctures nearly 

 simple throughout and not denser laterally, arranged in very feebly defined 

 unimpressed rows, approximate toward the suture, then widely distant, with 

 an uneven and sparser row along the middle of the intervals. Ler/s moderate 

 in length and very slender ; anterior femora not dentate but with a very broad 

 and obtuse rounded salient near the apex ; spurs of the anterior tibiffi very 

 slender and almost exactly equal. Length 13.0 mm. ; width 6.0 mm. 



California (Iloopa Yalley, Humboldt Co.). 



The unique type of this species is one of the most symmetrically 

 proportioned insects of the family. There is no described species 

 with which it can be compared, but for the present it may be placed 

 near dentipes. 



E. Iiriiniiipes n. sp. — Rather robust, moderately convex, coarsely, 

 densely sculptured and dull, black ; legs dark brown throughout. Ileud 

 large, fully two-thirds as wide as the prothorax, coarsely, extremely densely 

 punctate and scabrous ; antennae longer than the head and prothorax, rather 

 slender, third joint about fonr times as long as wide. Piothorax scarcely one- 

 tliird wider than long; base and apex very nearly equal in width, sixbtrun- 

 cate ; apical angles obtuse, not distinctly rounded, not at all prominent ; basal 

 right, not rounded ; sides strongly angulate at the middle, thence very feebly 

 arcuate to the apex and broadly sinuate to the base ; disk moderately, evenly 

 convex throughout, very coarsely, deeply and confiuently punctate. Elj/tra 

 at base nearly one- third wider than the contiguous base of the prothorax, 

 very slightly more than twice as long as the latter, abruptly and obtusely 

 roiinded behind when viewed vertically ; sides strongly arcuate behind, gradu- 

 ally convergent and straighter thence to the humeri, which are slightly obtuse 

 but scarcely at all rounded ; disk widest behind the middle, where it is from 

 one-third to two-fifths wider than the prothorax, feebly convex above, strongly 

 so laterally, coarsely, densely, asperately punctate, the asperities arranged 

 without trace or order. Lr(/s moderate in length, somewhat slender. Length 

 U.12-'J.5 mm. ; width 4.3-4.U mm.
