ClCINDELID^E 25 



Omus tularensis ssp. remissus nov. Shorter than usual and strongly 

 ventricose, strongly alutaceous, the elytra more shining; color throughout 

 dark red-brown in the type but probably from immaturity; head dis- 

 tinctly narrower than the prothorax, almost smooth, with some very 

 obsolete minute frontal punctures; labral lobe very large, prominent, 

 faintly truncate medially; antennae moderately long and slender; pro- 

 thorax very much smaller and more obtrapezoidal than in tularensis, 

 being more nearly as in gracilior, a fourth or fifth wider than long, the 

 sides feebly and unevenly arcuate, the side margin joining the basal 

 bead, the base very broadly and feebly bisinuate; surface smooth, rugu- 

 lose basally but scarcely at all so apically; elytra short and strongly 

 convex, less than one-half longer than wide, nearly one-half wider than 

 the prothorax, oblong-oval, parallel, rapidly obtuse apically, the humeri 

 rather pronounced; punctures moderately small and very feeble inden- 

 tations, gradually becoming altogether obsolete basally; legs moderate, 

 the tarsi long. Male unknown. Length (9 ) 16.0 mm.; width 6.0 mm. 

 California (Colony Mill, Tulare Co., 5400 ft.), Hopping. 



Differs very much from either tularensis or gracilior in the abbre- 

 viated hind body, and, from the former, more especially in its 

 much smaller and more basally narrowed prothorax. 



The following is a rather distinct subspecies of lavis Horn, of 

 which species I now have three perfectly homogeneous examples: 



Omus laevis ssp. peropacus nov. Male rather narrow and subde- 

 pressed, only feebly ventricose, densely opaque throughout the upper 

 surface, more shining beneath; head only very slightly narrower than the 

 prothorax, very obsoletely and obtusely rugulose, the impressions feeble 

 but long and oblique, the middle of the front with extremely ill-defined 

 sparse punctures; labral lobe broad, slightly advanced, with its edge 

 undulated; antennae rather long, moderately stout; prothorax only a 

 fifth or sixth wider than long, the sides moderately converging and very 

 evenly arcuate from apex to base, the side margins finely reflexed, a little 

 more so basally, attaining the base, the basal bead coarse, only visible 

 laterally; surface feebly convex, densely dull but in general perfectly 

 smooth, slightly rugose at base, the anterior transverse impression broad 

 and indefinite, more acute toward the sides, the subbasal very feeble, 

 the median stria fine but distinct; elytra oblong, two-thirds longer than 

 wide, not a third wider than the prothorax, widest at the middle, the 

 sides parallel and broadly, evenly arcuate, more converging behind from 

 near the middle, the humeri slightly evident though gradually broadly 

 rounded; surface flat suturally, having very fine and remote, indefinite 

 punctures, joined by a system of irregular and feebly impressed sub- 

 longitudinal creases; anterior tarsi with the three joints differing but 

 little in width. Length (cf) 15.8 mm.; width 5.65 mm. California 

 (Tulare Co.). 



From the male of Icevis this differs in its much more parallel hind 

 body, more depressed and less smooth elytra and more nearly 

 parallel three basal joints of the anterior tarsi.
