finely, sparsely punctate, otherwise nearly as in confertus, the metastemum a 

 little more sparsely punctate. Legs slender ; basal joint of the hind tarsi 

 distinctly longer than the remainder. Length 5.8-6.6 mm. ; width 2.3—2.6 mm. 



California (Coronado Beach, San Diego Co.). Dr. Blaisdell. 



This species is allied to confertus, but differs in its larger size, 

 more elongate form, more slender antennae and longer basal joint 

 of the hind tarsi. The prothorax, especially, is longer and with the 

 apex more transverse. I have not positively identified the sexes in 

 the two individuals before me, but it is probable that the sexual 

 difference in the eyes is not marked. 



41 H. macer n. sp. — Oblong-oval, somewhat convex, rather shining, pale 

 rufo-testaceous, sometimes slightly brownish, the legs more flavate ; pubescence 

 very short, dense, pale, moderately conspicuous. Head feebly convex, the 

 interocular surface finely, rather sparsely punctate in the male, the eyes in 

 that sex moderately large, separated by fully three-fourths of their width ; 

 antennae stout, distinctly more than one-third as long as the body, very feebly 

 attenuate, the intermediate joints short, scarcely one-fourth longer than wide, 

 strongly obconical, the third more slender and scarcely perceptibly longer 

 than the fourth. Prothorax about one-half wider than long, the apex two- 

 thirds as wide as the base, feebly arcuate ; sides broadly arcuate and conver- 

 gent anteriorly, nearly parallel and very feebly arcuate toward base, the 

 angles slightly obtuse ; base transverse, the sinuations small and feeble ; disk 

 broadly, just visibly impressed in the middle toward base, rather finely, 

 extremely densely punctate, the punctures in contact and sometimes slightly 

 rugulose, the lustre however rather shining. Elytra fully three times as long 

 as the prothorax and just visibly wider, the apex gradually ogival, the humeri 

 narrowly exposed, rounded ; sides parallel and almost straight in basal two- 

 thirds ; disk with very fine, feebly impressed striae of fine, inconspicuous 

 punctures, the intervals rather strongly shining, nearly flat, finely, extremely 

 densely, confusedly punctate. Under surface finely, sparsely punctate, the 

 prosternum and its side-pieces very densely so. Legs rather slender, the basal 

 joint of the hind tarsi nearly as long as the remainder. Length 5.0-5.8 mm. ; 

 width 2.0-2.2 mm. 



California (Poway, San Diego Co.; Folsom). 



A rather inconspicuous, unusually pale species, somewhat dis- 

 tantly related to deplanatus and distinguishable by its much more 

 convex form and slightly longer prothorax. 



In deplanatus the punctures of the pronotum are small, circular 

 and distinctly separated, while in the present species they are quite 

 peculiar, giving under small magnifying power, the rugulose appear- 

 ance mentioned in the description. The punctures in macer are 

 much larger than in deplanatus, slightly elongate, closely crowded
