TENEBRIONID/E 113 



Body very much more slender, very convex, deep black, anteriorly opaque, 

 the hind body shining; head obsoletely impressed, finely, very sparsely 

 punctate; prothorax (9 ) small, about as long as wide, widest slightly 

 before the middle, parallel, the sides broadly, feebly arcuate, slightly 

 sinuate basally, the basal angles rather strongly, obliquely prominent 

 and acute; surface as in carinatus but with the punctures very small, 

 largely wanting on the slope of the carina anteriorly, stronger, 

 closer laterally, the edge narrowly and distinctly reflexed and finely 

 crenulate; median carina extending almost to the base; elytra nearly 

 three-fourths longer than wide, evenly oval, very strongly, evenly 

 convex from side to side, almost smooth, feebly, irregularly wrinkled, 

 with some short transverse impressions along the margins and costa; 

 inner costa obsolete, represented by a feeble swelling; abdomen 

 alutaceous, closely, strongly and asperulately punctate and with 

 minute blackish hairs. Length ( 9 ) 18.5 mm. ; width 8.4 mm. Cali- 

 fornia (San Felipe) sophistes n. sp. 



3 Oblong-elongate, deep black, opaque anteriorly, the hind body not- 

 ably shining; head with the fine punctures moderately sparse; pro- 

 thorax large, slightly wider than long, parallel, widest at about the 

 middle, nearly as in carinatus, the edge very thick and finely crenu- 

 late, the carina obsolescent behind the middle, the punctures very 

 coarse and confluent basally, coarse but separated laterally, fine 

 and close near the carina anteriorly but larg elywanting on its slopes; 

 sides broadly deplanate, not evidently reflexed; elytra two-thirds 

 longer than wide, two-fifths wider than the prothorax, nearly parallel 

 and feebly arcuate at the sides, the rounded humeri unusually evi- 

 dent; surface nearly as in sophistes, except that the sutural parts 

 between the two costse are much less convex; abdomen similarly 

 but less closely punctate. Length (cf) 19.0-19.5 mm.; width 9.0- 

 9.4 mm. Lower California quadripennis n. sp. 



Among the three examples of carinatus before me the male is 

 decidedly larger than either of the two females, but does not differ 

 much in form, except in the evidently larger prothorax and the 

 notably longer as well as thicker legs. 



Group III Type actuosus Horn. 



Prothorax strongly reflexed at the sides, the surface not granose, more 

 or less finely, sparsely punctate, the punctures simple or slightly 

 asperulate 2 



Prothorax not reflexed but deplanate at the sides, the surface granose 

 at least medially except in opimiis 3 



Prothorax densely and roughly punctate, not reflexed at the sides, 

 strongly obtrapezoidal 6 



2 Form strongly ventricose in both sexes, deep black, moderately 

 opaque, the elytra and abdomen rather shining; head feebly, in- 

 definitely impressed, finely and sparsely punctate, the minute hairs 

 erect, dark and inconspicuous; prothorax a third to nearly half (9 ) 

 wider than long, widest slightly before the middle, scarcely more than
