Dec, 1904.] SCHAEFFER : NeW CoLEOPTERA. 233 



a moderately long sharp tooth, tibiae strigose punctate, slightly curved, front pair 

 broadly dilated within about middle, middle and hind pair sinuate within near apex. 

 Abdomen shining, coarsely not densely punctate. Length, 3.5-4 mm. 



Four specimens, Brownsville, Texas (Esperanza Ranch), May, 

 June and July, in the Museum of the Brooklyn Institute. 



This species is very distinct from the North as well as the Central 

 American species by the general form, strongly costate apical half of 

 elytra and the punctuation of the prothorax. 



Chalcodennus serripes Fahr. 



This species occurs from Brownsville, Texas to Brazil. It is 

 easily distinguished by its narrow, somewhat compressed, elongate 

 elytra and the tibije serrulate within. The color is seneocupreous, 

 elytra rufous with a slight metallic tint, with rows of large punctures, 

 and the thorax oblique-strigose. 



Chalcodermus vittatus Champ. 



Specimens of this species, which is described from Guatemala, 

 were taken at Brownsville (San Tomas and Esperanza Ranch from 

 May to July). 



It is a short, oval insect, seneo-cupreous, elytra rufous, with the 

 suture, the second interstice at middle, the fourth at apex and base, 

 and the sixth for nearly the entire length, aeneous. In one specimen 

 the fifth at apex is also aeneous. The thorax is oblique-strigose. 



Toxotropis irroratus, new species. 



Blackish brown, irrorate with yellowish white hairs on thorax and elytra. Head 

 and prothorax densely punctured, the ante-basal ridge of the latter feebly arcuate, 

 color blackish brown, with patches of white hairs. Eyes moderately deeply emargi- 

 nate. Elytra with rows of moderately coarse punctures, intervals flat densely punc- 

 tured, surface densely clothed with brown hairs, concealing the surface sculpture, 

 irrorate with patches of white hairs, forming an irregular arcuate fascia near base. 

 Body beneath black, moderate densely clothed with white hairs. Femora piceous, 

 tibije and tarsi fulvous, the latter at apex black, claws deeply cleft, the inner portion 

 convergent. Length, 2.5-3 irini- 



Brownsville, Texas (Esperanza Ranch and San Tomas), April to 

 June. Four specimens in the Museum of the Brooklyn Institute. 



This species will readily be distinguished from our other species 

 by the deeply cleft claws ; the eyes seem to be also more emarginate. 

 Both characters somewhat bridge over the differences between the 

 genera Toxotropis and Gonops.
