CONOTRACHELUS. 413 
sete along each interstice. Head densely, rugulosely punctate, flattened between the eyes above; 
rostrum stout, curved, scarcely longer than the prothorax, rugosely punctate and tricarinate (the median 
carina sharp), the antennse inserted near the tip, joints 1 and 2 of the funiculus subequal in length. 
Prothorax transverse, narrowed and constricted in front, feebly bisinuate at the base; coarsely, densely 
punctate. Elytra less than twice the width of the prothorax, compressed below the rounded humeri, 
and narrowing from about the basal fourth ; coarsely seriate-punctate, the punctures subquadrate, the 
interstices densely, finely rugulose and faintly granulate, 3, 5, 7, and 9 moderately costate, the ridge 
on 3 abruptly interrupted beyond the middle and also (like that on 5) slightly depressed below the base. 
Ventral segments coarsely, densely punctate. Mesosternum flattened between the coxe. Legs rugosely 
punctate ; femora somewhat feebly unidentate; tarsal claws with a very long curved tooth. 
Length 42-43, breadth 24-22 millim. (¢.) 
Hab. Mexico, Huetamo in Michoacan (Hoge), Dos Arroyos in Guerrero (H. #. 
Smith). 
Two specimens, one partially abraded. Superficially not unlike C. lewcopheatus, 
but shorter and broader, the prothorax wanting the carine on the anterior part of 
the disc, the ridge on the third elytral interstice abruptly interrupted beyond the 
middle, the vestiture differently arranged. C. nivosus, Lec., and C. similis, Boh., of 
North America, are also somewhat like the present species. 
131. Conotrachelus cinerascens, sp. n. (Tab. XX. figg. 26, 26a; 264, 
tarsal claw.) 
Subovate, slightly shining, nigro-piceous, the antenne and the tips of the tarsi ferruginous ; the vestiture 
close, whitish beneath and on the legs, that on the upper surface ochreous or brownish intermixed with 
white, the prothorax with a condensed, curved, white line on each side of the disc and a straight one 
down the middle, the humeri also white in front, the elytra with numerous scattered fine whitish sete, 
the femora with a faint white ring. Head densely punctate, shallowly foveate between the eyes ; 
rostrum moderately stout, slightly curved, about as long as the head and prothorax, closely, rugulosely 
punctate and with an indistinct median carina, the apical portion somewhat thickly punctured, the 
antenne inserted at about one-third from the tip, joints 1 and 2 of the funiculus subequal in length. 
Prothorax transverse, much narrowed and slightly constricted in front, parallel behind, feebly bisinuate 
at the base; densely, rugulosely punctate. Elytra rapidly narrowing from about the basal third, 
parallel in front; punctate-striate, the interstices closely, rugulosely punctate, and each with a scattered 
series of rather coarse setigerous impressions, 3, 5, 7, and 9 finely, uninterruptedly costate. Intermediate 
coxe distant, the mesosternum flat, vertical in front. Ventral segments shining, rather sparsely, 
moderately coarsely punctate. Legs comparatively slender; femora clavate, rather feebly unidentate ; 
tarsal claws with a very long, stout, flattened tooth, which is obliquely truncate at the apex. 
Length 54-64, breadth 35-3} millim. (¢%) 
Hab. Mexico, Toxpam (Sallé), Jalapa (Hoge). 
Three specimens. A species easily recognizable by the peculiar form of the 
tarsal claws.
