336 MEMOIRS ON THE COLEOPTERA 



Hypherpes protensipennis n. sp. Body narrow, very elongate, mod- 

 erately convex, rather shining, black throughout above and beneath, the 

 legs piceous; head nearly as in the preceding throughout, the eyes a little 

 larger and more prominent than in sierranus; prothorax slightly elon- 

 gate, widest near anterior third, the sides subevenly and moderately 

 rounded, gradually becoming faintly sinuate basally, finely but strongly 

 reflexed; base feebly sinuate medially, distinctly narrower than the apex, 

 rounded laterally, causing the sharp basal angles to be slightly more than 

 right, margined feebly only very near the angles; apex nearly as in mer- 

 cedianus; impressions faint; median stria 'moderately impressed; inner 

 fovea broadly impressed, less than a fourth the total length and not 

 attaining the base; surface thence to the sides unmodified; elytra very 

 nearly twice as long as wide, fully two-fifths wider than the prothorax, 

 the parallel sides feebly arcuate, more rounding at base; striae strong, 

 rather deep and notably punctulate throughout, the scutellar moderate 

 but distinct, oblique; intervals rather convex, especially toward the sides. 

 Length (a 71 9 ) 14.5 mm.; width 4.8-4.9 mm. California. Two Levette 

 specimens, probably from the Sierran regions. 



This species is also allied to sierranus and the type pair was in- 

 cluded under the description of the latter; it differs, however, in its 

 narrower outline, larger eyes, more finely reflexed thoracic sides 

 and more elongate and narrower elytra, with more punctured striae. 

 From mercedianus it differs in the more elongate basal sinus of the 

 thoracic sides, less convex elytra, with more punctured striae and 

 distinct scutellar stria and, from annosus, in its convex and not 

 flat strial intervals. 



Leptoferonia n. gen. 



Although not distinguished by any apparent structural charac- 

 ters affecting special organs, there is a small group of relatively 

 minute, more or less parallel species, allied to angustus Dej., which 

 look decidedly out of place among the much larger species of Hy- 

 pherpes, both in size and outline of the body, and it is probably well 

 worth while to form a separate genus of them, although there is some 

 diversity in several important characters, such as the margination 

 of the thoracic base and presence or absence of a carinule near and 

 parallel to the basal part of the thoracic side margins, which in all 

 cases are very finely reflexed. The elytral striae are complete and 

 in most cases are equal throughout, well impressed and completely 

 impunctate in every species known to me at present, excepting 

 pumilus. In my previous studies I made two groups of the species, 

 but this seems now unnecessary and Leptoferonia, as defined in the
