REVISION OF TENEBRIONID SUBFAMILY CONIONTIN^ 1 25 



deep, broadly parabolic, the anterior canthus oblique, subacute, 

 as prominent as the posterior ; antennae slender, the joints notably 

 elongate ; prothorax as in extricata but shorter, fully three-fifths 

 wider than long, the punctures similar but much more close-set 

 throughout and without median impunctate line ; scutellum sim- 

 ilar ; elytra as in extricata but narrower and more nearly one- 

 half longer than wide, more gradually acute at apex, still less 

 coarsely and more sparsely punctate, similarly rugose posteriorly ; 

 prosternum finely but very strongly, moderately closely punctate 

 and puberulent, the process very strongly beaded along the sides 

 to the apex but not around the latter ; hind femora excessively 

 minutely and remotely punctulate throughout, the abdomen not 

 very finely though sparsely, strongly and conspicuously punctate. 

 Length 9.5 mm. ; width 4.35 mm. (9). San Francisco Co. 



marginata n. sp. 

 Form narrower and more elongate, moderately convex, alutaceous, the 

 elytra polished, somewhat piceous black, the tarsi piceous and the 

 antennal apex rufous ; head moderate in size, strongly, rather 

 closely punctate, sparsely pubescent, the sinus moderately narrow 

 and deep, parabolic, the lobes broadly rounded, the anterior can- 

 thus oblique though obtusely rounded, as prominent as the pos- 

 terior ; prothorax three-fifths wider than long, the sides rounding 

 and convergent anteriorly, becoming subparallel and straight or 

 sometimes with a feeble sinus in more than basal half, the apex 

 rather shallowly sinuate, two-thirds as wide as the base, the angles 

 slightly obtuse but only narrowly rounded ; surface finely though 

 strongly, only moderately sparselv punctate, strongly but not 

 much more closely toward the sides, the bead not very thick 

 though prominent, slightly curving inward at base ; scutellum 

 moderate, transversely triangular ; elytra one-half longer than 

 wide and somewhat gradually acutely ogival behind (?), or two- 

 fifths longer than wide and more obtusely parabolic. at apex (cf), 

 rugose posteriorly, the punctures rather coarse and well separated, 

 notably unequal ; prosternum finely, sparsely punctate, puberu- 

 lent, the process rather narrow, somewhat strongly margined to, 

 but scarcely about, the rounded apex ($), or a little wider and 

 finely margined and only at its base (cJ*) ; hind femora and abdo- 

 men minutely, sparsely and more or less inconspicuously punc- 

 tate. Length 7.7-9.0 mm. ; width 3.5; -4.0 mm. San Francisco. 

 Taken in the suburbs rather plentifully by the writer and also 

 received from the County, collected by Mr.Fuchs. 



nemoralis Esch. 



Form rather shorter than in nemoralis^ still smaller in size, similar in 

 coloration and lustre ; head rather small, strongly, somewhat 

 closely punctate, the sinus moderately wide and deep, circularly 

 rounded, the anterior canthus oblique, subacute, less prominent 

 than the posterior ; antennae notably thick, the joints only moder- 

 ately elongate ; prothorax large, nearly three-fifths wider than 

 long, the sides broadly arcuate, more strongly so and very con-
