rather coarsely, verj' feebly and rather sparsely puuc'ate; median impnnctate 

 area rather broad, snb-fnsiform; epistoma moderately produced, broad, fee'ly 

 and abruptly arcuate in the middle at the apex; anteunal tuberculutious small 

 and rather couspicU'Uis; autenniB nearly as long as the head and prothorax 

 together; basal joint as long as the next two combined, second more than 

 twice as long as wide, very slightly shorter than the third, distinctly longer 

 than the foiirth, tenth as long as wide. Prothorax slightly wider than long, 

 very slightly narrower than the head; sides distinctly convergent posteriorly 

 throughout and nearly straight; basal angles very obtuse and very slightly 

 rounded, sides of the base thence strongly convergent and broadly arcuate to 

 the median portion which is almost squarely truncate; apex broadly and 

 very feebly arcuate; nnchal emargination very feeble, nearly one-half as wide 

 as the disk; ajncal angles rather narrowly roiinded; disk rather coarsely, ex- 

 cessively feebly and very sparsely punctate; median impunctate area broad, 

 equal thi'oughout, surface not impressed. Elytra at base slightly wider than 

 the prouotum; sides almost parallel and very slightly arcuate; together 

 broadly, sub-angularly and very feebly sinuate behind; disk broadly and 

 feebly convex, narrowly and rather strongly impressed along the slightlj' ele- 

 vated suture, scarcely one-fourth longer than wide, oue-third longer than the 

 prouotum, rather finelj^, evenly, strongly, i*ather densely and sub-asperately 

 punctate. Abdoinen rather short and broad, slightly narrower than the 

 elytra; sides parallel and slightly arcuate; surface very finely, densely and 

 sub-asperately punctate. Leys rather short and robust; anterior tarsi slightly 

 dilated; first joint of the posterior one-half longer than the second, nearly 

 twice as long as the fourth and slightly shorter than the fifth. Length 

 4.1 mm. 



Lake Co., 1 (Mr. Fuclis); Soutliern Cal., 1 (Mr. G. W. 

 Dunn), 



The two specimens, of which the first is the type, are both 

 females, and agree tolerabl}- well together, although the one 

 from the possible neighborhood of Los Angeles, has the 

 head slightly narrower and more strongly arcuate behind 

 with the basal angles more broadly rounded, the prothorax 

 very slightly longer, and the elytra very slightly shorter and 

 more finely punctate. There is a strong probability of its 

 being at least a well-marked variety, although lack of ma- 

 terial prevents any judgment as to the amount of specific 

 variation; in other portions of this group, however, where 

 the material is ample, the specific variation is seen to be 

 very slight.
