REVISION OF TENEBRIONID SUBFAMILY CONIONTIN^E 157 



Form relatively a little broader, castaneous in color, the anterior parts 

 more blackish ; head nearly similar though notably smaller, barely 

 two-fifths as wide as the prothorax, the antennae only moderately 

 enlarged distally ; prothorax similar though a trifle more trans- 

 verse and similarly sparsely and strongly, though not coarsely, 

 punctate, more sparsely so laterally and with much less difference 

 in the size of the larger and smaller punctures, the sides less 

 abruptly, more declivously and somewhat more broadly explanate ; 

 elytra similar though not at all longer than wide, the punctures 

 throughout similarly sparse but not quite so coarse ; prosternal 

 process slightly more strongly constricted. Length 5.6-6.5 mm. ; 

 width 3. 6-4. i mm. Redondo SCOlopax n. sp. 



ii Body stout, oblong, but little longer than wide, dark piceo-testa- 

 ceous throughout; head small, scarcely more than a third as wide 

 as the prothorax, densely punctate throughout, more coarsely 

 behind, more transversely rugose and medially swollen before, the 

 transverse suture ; antennae relatively more dilated apically or slender 

 basally than usual ; prothorax fully two and three-fourths times as 

 wide as its median length, inflated and with strongly rounded 

 sides basally, the sides very strongly converging and less arcuate 

 thence to the apex, the angles narrowly rounded ; surface closely, 

 rather coarsely punctate, the latter not differing in density but com- 

 posed of mingled coarse and finer punctures laterally, broadly 

 declivo-explanate at the sides, the bead fine but strong ; elytra 

 barely as long as wide, very broadly rounded behind from above, 

 the sides becoming subparallel and broadly arcuate in about basal 

 half, the sculpture more coarsely and closely muricate than in the 

 two preceding species, granulose and smaller posteriorly but having 

 the surface between the granules not at all alutaceous; pro- 

 sternum coarsely and densely punctured, the process strongly con- 

 stricted ; abdomen finely and sparsely punctured medially. Length 

 4.97.0 mm. ; width 3.04.5 mm. San Diego, G. W. Dunn. 



amplicollis n. sp. 



Body similarly very stout and subquadrate, larger in size, deep black 

 in color, the antennae pale, the legs piceous, similarly polished 

 throughout ; head larger, fully two-fifths as wide as the prothorax, 

 similarly densely sculptured, coarsely behind the suture, rather 

 more loosely so and finely rugose before the latter, the antennae 

 nearly similar ; prothorax a little less transverse, the sides similarly 

 inflated posteriorly but less converging anteriorly, the angles dis- 

 tinctly though not very broadly rounded ; surface similarly coarsely 

 and closely, though a little more loosely, punctate, less abruptly 

 and rather less widely declivo-explanate laterally, the bead simi- 

 larly strong but not so elevated ; elytra similar, scarcely as long 

 as wide, the sides becoming parallel and more feebly arcuate 

 before the middle, the very coarse sculpture almost similar ; pro- 

 sternal process somewhat less strongly constricted, the neck about 

 two-thirds as wide as the rounded and dilated posterior portion ;
