1 66 MEMOIRS ON THE COLEOPTERA 



without trace of humeri; surface very feebly convex, the striae very 

 fine and finely, obsoletely sculptured, the intervals nearly flat, the 

 third with four punctures, the sides rather strongly and very abruptly 

 reflexed, the apices obliquely feebly sinuate, the tips not prolonged 

 but separately angulate, the angle only moderately sharp; legs long 

 and slender, the anterior tarsi simple, the posterior strongly grooved 

 at the sides as usual, nearly four-fifths as long as the tibiae. Length 

 (cf) 1 1. 2 mm.; width 3.75 mm. California (Truckee, near Lake 

 Tahoe) jejuna Lee. 



Body in color, lustre and general form as in the preceding but still more 

 slender; head more elongate, nearly four-fifths as wide as the pro- 

 thorax, the neck narrower, the eyes similar; antennae a little less 

 slender, the third and fourth joints actually not so long but of the 

 same relative proportion; prothorax narrower, fully a fifth longer 

 than wide, similar in form, except that the sides are more broadly 

 arcuate and, toward base, become only oblique and very feebly 

 sinuate, not at all parallel near the angles, which are slightly obtuse 

 as well as distinctly rounded; base similar but barely visibly narrower 

 than the apex, nearly three-fifths the maximum width; surface nearly 

 similar throughout, except that there is a feeble impression extending 

 almost from apex to base and parallel to the side margins at a con- 

 siderable distance therefrom: elytra still more nearly twice as long 

 as wide, a little narrower, not definitely widest posteriorly, the surface 

 and margins similar, the striae even finer and feebler and the apices 

 more obliquely sinuate but with each tip evenly and broadly rounded ; 

 legs and tarsi nearly similar, the hind trochanters short and with 

 the apex very obtuse, almost arcuato-truncate. Length (cf) n.o 

 mm.; width 3.5 mm. California. Labelled simply "Cal." in the 

 Levette collection gracilenta n. sp. 



8 Head barely visibly narrower than the prothorax. Body shining and 

 pale testaceous throughout, the elytra feebly alutaceous, rather 

 strongly ventricose; head elongate, the eyes rather large but only 

 moderately convex, equal in length to the oblique sides behind 

 them; antennae long, very slender and filiform, much more than 

 half as long as the body, the third joint a third longer than the fourth, 

 all the joints very long; prothorax two-fifths longer than wide, 

 widest near apical third, the sides rounded, very gradually converging 

 posteriorly, becoming very slightly sinuate near the basal angles, 

 which are nearly right and moderately reflexed but not prominent 

 or very .sharp; base sinuate medially, arcuate at the sides, one-half 

 the maximum width and three-fourths as wide as the apex, which is 

 transverse, with the angles barely at all advanced, slightly more than 

 right and very narrowly blunt; surface feebly convex, feebly im- 

 pressed nearly throughout at some distance from the rather strongly 

 and abruptly reflexed margins, the impressions deeper basally, 

 impunctate, the median stria fine but strong, subentire; elytra evenly 

 oval, widest at the middle and about two and one-half times as 

 wide as the prothorax, nearly three-fourths longer than wide; surface 

 very feebly convex, the striae very fine and feeble, the intervals 

 not quite flat, the third with four punctures, the side margins rather
