REVISION OF TENEBRIONID SUBFAMILY CONIONTIN^ 1 29 



evenly bisinuate, with the angles rather acute and posteriorly pro- 

 duced, the apical angles moderately rounded, right ; surface finelv, 

 not very sparsely punctate, becoming strongly and unusually closely 

 so laterally, the bead moderately fine; scutellum rather small, not 

 very transversely triangular ; elytra one-half longer than wide, 

 much less gradually rounded and narrowed behind than in shas- 

 tanica, obtusely ogival at tip ; surface nearly smooth, with notice- 

 ably small and unusually close punctures, but strongly rugose and 

 more coarsely punctate on the declivity, where each puncture has 

 a very minute silvery seta entirely enclosed within it ; prosternum 

 nearly as in shastanica but with the process more elongate, more 

 constricted, strongly margined except at the rounded apex, which 

 is unmargined ; hind femora and abdomen finely, sparsely and in- 

 conspicuously punctate. Length 12.3 mm.; width 1^.9 mm.

23 — Prothorax large, a little wnder than the elytra 24 



Prothorax not at all wider than the elytra 25 



24 — Form oblong-elongate, very convex and strongly shining through- 



out, very deep black, the elytral punctures with sette so minute as 

 only to be observed under rather high power ; head somewhat finely 

 but strongly, moderately sparsely punctured, the sinus rather wide 

 and shallow, the anterior canthus broadly rounded, even a little 

 more prominent than the posterior ; prothorax nearly four-fifths 

 wider than long, the sides subparallel and feebly arcuate, round- 

 ing and strongly converging anteriorly, the apex broadly sinuate, 

 three-fifths as wide as the base or a little more (d^), the angles 

 obtuse and rounded ; base subtransverse, with the angles but feebly 

 and gradually produced and rounded ; surface excessively minutely 

 and remotely punctulate, more visibly but still very finely and 

 remotely so laterally, the sides narrowly explanate and with a 

 rather coarse bead ; scutellum rather large, transversely and 

 obtusely triangular ; elytra two-thirds longer than wide, straight 

 and parallel at the sides, very gradually narrowed and somewhat 

 acutely produced at apex, nearly smooth, very coarsely and sparsely 

 punctate, more closely so but only slightly rugose on the declivity ; 

 prosternal process but feebly constricted, strongly margined at the 

 sides but. unmargined at apex ; abdomen extremely minutely, 

 remotely punctulate, the hind femora with sparse but rather 

 strong — though small — punctures. Length 11,7-13.5 mm.; 

 width 5.4-6.1 mm. San Francisco. \^=:- incEqualis ^?>y^.

Form narrower, deep black, less shining, the elytral punctures pos- 

 teriorly each with a very small but more visible seta ; head very 

 finely, rather sparsely punctate, the sinus broad but rather deep, 

 parabolic, the lobes less obtuse, the anterior canthus oblique and 

 much less rounded, obtusely subangulate, as prominent as the 

 posterior ; prothorax less transverse, nearly three-fourths wider 

 than long, the sides more evenly rounded, gradually more con-
