Claws strongly serrate, antennas flabellate in male, serrate in female from the 

 fifth joint ; hind tibise at apex with two moderately long sharp spurs, fourth 

 joint twice as long as the third, eyes separated in front by a very narrow line. 



Pelecotoiiioides nubilus Gerst. 

 Eyes entirely divided by a broad plate. 



Claws serrate, antennae flabellate in the male, serrate in female from the fourth 

 joint Toposcopits zvrightii Lee. 



Constrachelus rubescens, new species. 



Blackish brown, sparsely clothed with white hairs, and denser reddish-yellow 

 hairs at base of thorax, base and apex of elytra. Beak slender, curved, as long as 

 the head and thorax, carinate at middle, striate at sides. Head coarsely punctured, 

 clothed sparsely with reddish hairs which extend to the middle of the beak. Pro- 

 thorax wider than long, slightly constricted in front, sides feebly arcuate, base bisinuate, 

 disk carinate, densely rugosely punctured, clothed with white and reddish-yellow 

 hairs, the first very sparse, the latter more densely near base. Elytra nearly twice 

 as wide as the thorax, base sinuate, humeri broadly rounded disk with rows of coarse, 

 closely placed punctures, alternate interspaces, carinate, carina of the third interval 

 twice, but not abruptly interrupted, that of the fifth very feeble ; surface blackish 

 piceous, with irregular paler spots, clothed sparsely with white hairs and more densely 

 at apex and base with reddish-yellow hairs. Abdomen shining, coarsely and sparsely, 

 last ventral more densely punctured and with a shallow impression at middle. 

 Femora armed with a small tooth, anulated with reddish-yellow hairs. Claws 

 divergent, toothed. Length, 3. 15-3.5 vAva. 



Brownsville, Texas (Esperanza Ranch, San Tomas). Four speci- 

 mens in the Museum of the Brooklyn Institute. 



The small size and the coloration will make this species easily 

 recognizable from any of our Conotrachelus. It is intermediate be- 

 tween Leconte's Division I, A and B by having the costae on the 

 third interval interrupted and the femora unidentate. The species is 

 not a common one, only a small number were taken during the entire 

 time of my stay. 



Chalcodermus semicostatus, new species. 



Oval, convex, piceo-?eneous, antennse ferruginous, elytra strongly costate at 

 apical half only. Head finely punctate, eyes nearly contiguous, separated by a very 

 narrow line ; beak as long as head and thorax, slightly curved, finely punctate, punc- 

 tures slightly confluent at sides ; antennae inserted at middle. Prothorax slightly 

 broader than long, gradually narrowing to apex, sides nearly straight, constricted in 

 front, base bisinuate ; disk coarsely punctate, denser and somewhat confluently at 

 sides, intermixed sparsely with smaller punctures, at middle a narrow smooth median 

 line. Elytra very little wider than the thorax at base, feebly narrowing to apex, 

 humeri slightly oblique, disk with series of large not closely placed punctures, inter- 

 stices sparsely punctate, very feebly convex at basal half, becoming strongly costate 

 from about middle to apex. Legs stout ; femora closely and coarsely punctate, with
