Coleopterological Notices, IV. 503 



evenly arcuate ; disk rather finely, deeply and closely punctate, 

 with a narrow, feebly defined, abbreviated median line. Elytra 

 twice as long as the prothorax, very finely but deeply and abruptly 

 striate, the intervals flat, fully three times as wide as the grooves 

 and each with a single series of extremely minute, very remote and 

 subobsolete punctures, the setae not obvious. 



Macra somewhat resembles sparsa in outward habitus, but differs 

 in its still more slender form, finer, closer pronotal punctuation and 

 much more minute interstitial punctures. Length 2.9 mm. ; width 

 1.1 mm. 



California. Cab. LeConte. 



40 15a lis discipilla n. sp. — Oblong, slender, rather convex, black 

 throughout, the legs piceous ; integuments highly polished and with a pro- 

 nounced aeneous lustre. Head obsoletely punctate, the beak moderately 

 coarsely and closely so, distinctly arcuate and fully four-fifths as long as the 

 prothorax in the male, nearly straight and fully as long as that part in the 

 female ; antennae normal. Prothorax rather long, scarcely one-third wider than 

 long, the sides subparallel in basal three-fourths, then rather abruptly and 

 strongly rounded, thence strongly convergent and more or less sinuate to the 

 apex ; base two and one-half times as wide as the head, subtransverse and 

 straight, the median lobe rather large and distinct ; disk with scarcely a trace 

 of median impunctate line, the punctures moderately coarse, deep and some- 

 what close, about two-thirds as wide as the scutellum, rather uneven in dis- 

 tribution but generally separated by less than their own diameters. Scutellum 

 very small, slightly tumid, nearly circular. Elytra scarcely more than one- 

 fourth longer than wide, not quite twice as long as the prothorax, at the feebly 

 tumid humeri but slightly wider than the latter ; disk with rather fine but 

 abrupt, deep, obsoletely punctate grooves, the intervals wide, flat, each with 

 a single series of minute feeble and remote punctures, not confused on the 

 subsutural intervals. Abdomen finely, sparsely punctate. Length 2.5 mm. ; 

 width 1.0-1.15 mm. 



Indiana. 



A single pair, In the male the abdomen has a small and mode- 

 rately deep impression very near the base. The sexual disparity in 

 the form and length of the beak is rather unusual in Baris, although 

 common in those genera having a greater longitudinal development 

 of this part of the body ; it is also very noticeable in sparsa. This 

 species differs from serea, which it resembles in size, lustre and 

 elytral sculpture, in its narrower, more parallel form, longer, rather 

 more coarsely and decidedly more densely punctured pronotum, and 

 longer beak.
