THE CANADIAN ENTOMOLOGIST. 169 



, 



Madarellus punctatus, sp. nov. — A little shorter and more robust 

 than undulatus, black, polished, beak dark rufous. Head finely, sparsely 

 punctulate above the eyes, front more coarsely and closely punctate. 

 Beak strongly, evenly arcuate, feebly tapering, sparsely, finely punctured 

 at apex, more strongly toward the base. Antennse inserted near the 

 middle, first joint of funicle about as long as the three following, club 

 equal to the four preceding joints. Prothorax about one third wider than 

 long, parallel in basal three-fourths, strongly rounded in front and but 

 feebly constricted at apex, coarsely, closely punctate except along the 

 median line behind the middle, punctures becoming confluent laterally. 

 Elytra about one-fourth longer than the prothorax, and very slightly wider 

 at the humeri ; sides gradually convergent behind, disk feebly undulated ; 

 strise deep, finely punctate, intervals scarcely more than twice as wide as 

 the strise, each with a single series of not very fine punctures, separated on 

 an average by about four times their own diameters. Beneath strongly, 

 closely punctate. Femora all armed with a small acute tooth. 



Length, 2.8 mm. One example, San Jose del Cabo. Type in the 

 collection of the California Academy. 



Very distinct from undulatus and cuneatus by the coarser, closer 

 sculpture of the upper surface. Each puncture of the thorax and of the 

 elytral interspaces bears a very short, fine, whitish hair. 



Cossouus sulcirostris, n. sp. — Moderately convex, piceous, legs 

 rufous. Beak shorter than half the thorax, flattened cylindrical, feebly 

 dilated apically, very finely, sparsely punctate, with a long distinct sulcus 

 extending from the interocular puncture two-thirds the distance to the 

 apex. Scrobes beginning near the tip, not distinctly visible from the 

 front. Head, above the eyes, subimpunctate. Antennae about as usual, 

 the club nearly uniformly pubescent throughout. Prothorax longer than 

 wide, feebly constricted at apex, a little narrowed at base, sides broadly 

 arcuate, surface very coarsely punctate, closely at sides, more sparsely on 

 the disk, with a nearly smooth area on either side of the middle toward 

 the base, base not distinctly cariniform before the scutellum. Elytra 

 parallel, very slightly wider than the thorax, striae of coarse punctures, 

 which are separated by about half their longitudinal diameters, intervals 

 nearly flat, very finely, uniseriately punctulate. Beneath coarsely, rather 

 closely punctate, except the abdomen and middle portion of metasternum, 

 where the punctures are finer and sparser.
