In this species the pronotal hypomera are not distinctly impressed, 

 and in several other characters it makes a closer approach to Mecys- 

 mus than any other. 



7 It. validlis n. sp. — Elongate-oval, moderately convex, dark blackish- 

 castaneous ; legs piceo-rufous ; integuments rather distinctly atutaceous, the 

 elytra strongly but very minutely granulato-reticulate ; pubescence rather 

 long, especially toward the elytral apex, moderately coarse, pale flavate, very 

 sparse but distinct. Head transverse, feebly convex, rather coarsely, deeply 

 punctate, the punctures finer and denser toward the edges ; upper lobes of 

 eye large, separated by scarcely four times their own width ; antennae rather 

 slender, gradually and feebly dilated toward apex, third joint rather long, 

 nearly as long as the first two together and but slightly shorter than the 

 fourth and fifth, seventh much longer than wide. Prothorux nearly three- 

 fourths wider than long, the apex very much narrower than the base, the 

 sides evenly and very strongly arcuate throughout ; base transverse, the 

 lateral sinuations distinct ; disk much wider just behind the middle than at 

 base, the lateral basal impressions completely obsolete, the punctures rather 

 coarse, sparse near the middle where they are separated by about twice their 

 own widths, thence gradually dense toward the sides but not very coalescent. 

 Elytra fully three times as long as the prothorax and, at apical two-fifths, very 

 slightly wider than the latter ; disk with rather feebly impressed striae which 

 are rather coarsely punctate, the punctures deep, perforate and generally 

 separated by about twice their own diameters ; intervals five or six times as 

 wide as the strial punctures, nearly flat, finely and sparsely punctured. 

 Abdomen finely and very sparsely punctate, the pubescence moderate in length, 

 very sparse, flavate. Legs moderate. 



Male. — Anterior and intermediate tarsi nearly as in longulus; abdomen rather 

 narrowly and feebly impressed in the middle toward base, the punctures 

 broadly dense and rather coarser toward the middle of the basal segment, 

 fifth with a rounded impressed apical fovea. 



Length 7.5 mm. ; width 3.2 mm. 



California (southern). 



The single specimen serving as the type of this species differs 

 from the male of longulus in its more convex upper surface, aluta- 

 ceous lustre, much longer pubescence, finer, sparser punctuation of 

 the abdomen, larger size and several other characters. The punc- 

 tures of the elytral stria? are relatively not quite as coarse as in 

 longulus, although of the same general nature, and the intervals 

 are more finely punctured.
