it somewhat resembles in general outline, by its coarser and still 

 more closely crowded and opaque sculpture, coarser, deeper, more 

 perforate and much more even interstitial punctures, coarser grooves 

 and narrower intervals, and by its decidedly larger size. It is 

 represented by a series of nine specimens, exhibiting scarcely any 

 variation 



12 Onyctiobaris egena n. sp. — Oblong-oval, convex, very densely 

 sculptured but rather strongly shining, black, the prothorax beneath with a 

 piceous tinge ; head, beak and legs bright red ; seta? small, sparse and incon- 

 spicuous ; those arising from the punctures of the elytral strise about as long 

 as those of the intervals. Head shining, rather finely, deeply punctured, the 

 punctures separated by about their own widths ; impression rather strong ; 

 beak somewhat stout, evenly, moderately arcuate, feebly tapering toward 

 apex, shining, rather coarsely, deeply but not very densely punctate, about 

 as long as the head and prothorax ; antennae inserted at the middle, the basal 

 joint of the funicle scarcely as long as the next three, second fully three-fourths 

 longer than wide, third to seventh increasing in width, the former nearly as 

 long as wide, the latter strongly transverse, club rather small and narrow, not 

 abrupt. Prothorax one-fourth wider than long, the sides straight and just 

 visibly divergent from the base to apical third, then broadly rounded to the 

 small but distinct constriction ; apex very briefly tubulate, truncate and dis- 

 tinctly more than one-half as wide as the base, the latter rather deeply bi- 

 sinuate ; disk without trace of impunctate line, deeply, rather coarsely and 

 extremely densely punctate, the punctures three-fifths as wide as the scutel- 

 lum, rounded but in mutual contact. Scuteilum slightly transverse. Elytra 

 short, scarcely visibly wider than the prothorax and about one-half longer, 

 but slightly longer than wide, parabolic in outline, the humeri very slightly 

 prominent ; disk coarsely, deeply striate, the intervals subequal, narrow, not 

 distinctly wider than the grooves, each with a single even series of Very coarse 

 deep rounded and close-set punctures. Abdomen deeply, rather coarsely, 

 moderately closely punctured. Prosternum narrowly and just visibly im- 

 pressed in the middle, the coxae moderate, remote, separated by much more 

 than their own width. Length 2.7 mm. ; width 1.2 mm. 



Arizona (Pinal Mts.). Mr. H. F. Wickham. 



A small species belonging to a group in which the species become 

 rather closely allied. It perhaps approaches pauperella more nearly 

 than any other form here noted, but differs in its shorter elytra, 

 with smaller and less conspicuous setae and much coarser more 

 close-set interstitial punctures, and also in the coarser punctures of 

 the head and pronotum. From ambigua it differs in its smaller 

 size, narrower form, much shorter, less visible setae and narrower, 

 more coarsely, closely and evenly punctured intervals.
