434 Memoirs on the Coleoptera 



*Odontocorynus subglaber n. sp. — Elongate-suboval, convex, shining, 

 deep black throughout, the squamules above almost wanting on the 

 pronotum, very small, slender, sparse and inconspicuous on the elytra; 

 under surface with fine close-set punctures, bearing small slender and 

 rather well spaced white squamules, larger and dens,er toward the sides 

 of the met-episterna and last three ventral segments; beak in the male 

 very thick, moderately, subevenly arcuate, feebly tapering and as long 

 as the head and prothorax, the sides flattened, deeply sulcate, punctate 

 and dull; antennae inserted at three-fifths, imperfect in the type, but the 

 outer funicular joints are transverse and with coronae of smaller and 

 finer squamules than those of the preceding joints; prothorax only just 

 visibly wider than long, the sides feebly converging and slightly arcuate, 

 gradually and moderately convergent before about the middle, the apex 

 feebly subtubulate, half as wide as the base and perfectly simple at the 

 sides; punctures deep, moderately coarse, uniform and irregularly close- 

 set, separated by evidently less than their diameters; smooth median 

 line traceable centrally; scutellum small, quadrate, albido-squamose, 

 except along the middle posteriorly; elytra elongate, three-fourths longer 

 than wide, much wider than the prothorax and more than twice as long, 

 the sides feebly oblique, the humeri prominent and the apex circularly 

 rounded; striae moderately fine; intervals not coarsely but strongly, not 

 very densely but rugulosely punctate. Length (cf) 5.7 mm.; width 

 2.3 mm. Mexico (Puebla). 



There is no other species known to me with which this can be 

 closely compared, the general form and subglabrous upper surface 

 remind us of limatulus and vernicicollis, but the thoracic apex is 

 perfectly simple and not dentate at the sides, and, from any of the 

 forms allied to creperus Boh., it may be known by the subglabrous 

 dorsal surface, besides the absence of toothed sides of the thoracic 

 apex. 



*Odontocorynus limatulus n. sp. — Very elongate-oval and convex 

 shining, subglabrous above, the fine sparse hair-like squamules of the 

 elytra barely discernible; scutellum with some more distinct and close 

 white squamules, extending also but more sparsely upon the basal 

 thoracic lobe; under surface with slender white scales, very uniform and 

 well spaced; beak in the male thick, not as long as the head and pro- 

 thorax, strongly sculptured, straight, bent a little at the extreme base, 

 and, beyond the antennae, oblique; antennae inserted at three-fifths, the 

 outer funicular joints simple though gradually more transverse and 

 perfoliate, the basal tooth of the club rather large and angulate; pro- 

 thorax a fourth wider than long, the sides evenly arcuate, becoming 

 parallel basally; apex constricted, impressed dorsally, more than half 

 as wide as the base, the lateral tooth strong and acute; punctures coarse, 

 separated by less than their diameters medially, more or less confluent 

 laterally, the smooth median line distinct but not attaining the apex; 

 elytra one-half longer than wide, at the prominent humeri much wider
