dense, cinereous, nearly even throughout and composed of very 

 slender cinereous parallel scales ; beak ( $ ) rather short and stout, 

 not longer than the prothorax, the latter slightly wider than long, 

 rounded at the sides, strongly and densely punctate ; elytra about a 

 fifth longer than wide, the umbones feeble, the humeri moderately 

 exposed basally, rounded. Length, $, 3.7 mm.; width, 1.7 mm.

5 — Form stouter than in hesperis, as obese as in lineellus but much smaller 

 in size, with shorter prothorax, more ovally-rounded elytral apex, 

 obsolete umbones and less exposed humeri; vestiture nearly as in 

 hesperis, uniform throughout, pale cinereous, decidedly dense only on 

 the sutural interval and, as usual, on the scutellum ; beak ( $ ) rather 

 longer than the prothorax, black, with the extreme tip rufescent ; 

 prothorax wider than long, parallel, with moderately arcuate sides, 

 convex as usual, with the separate and evenly-distributed scales 

 streaming radially outward from a small spot near the middle of each 

 side, and thence pointing obliquely backward to the median line 

 throughout ; elytra only slightly longer than wide. Length, $ , 3.8 

 mm ; width, 1.8 mm. San Diego radians n. sp. 



Form less stout but with much denser vestiture than in any other of this 

 group, the elytral strife almost obliterated ; beak {$ ) almost as long 

 as in the female, distinctly longer than the prothorax, not at all pale 

 at tip ; prothorax almost as long as wide, the vestiture much denser 

 and more squamiform than in any other of the group, without trace 

 of the lateral abnormality of the preceding ; elytra distinctly longer 

 than wide, the vestiture dense and whitish along the suture and more 

 feebly on the fifth and seventh intervals at base and near the feeble 

 umbones, elsewhere yellowish ; antennae unusually long and slender.

6 — Body unusually narrow, elongate-oval, convex; scales very slender, 

 sparse throughout, not very dense even along the suture ; beak ( $ ) 

 black throughout, slender, slightly longer than the prothorax, the 

 latter wider than long, narrowing anteriorly from only a little before 

 the middle, closely and strongly punctate, the vestiture fine ; elytra 

 two-fifths longer than wide, narrowing apically from only slightly
