15. BELONUCHUS CACAO, new species 



Description. — Head ruf opiceous, pronotum rufous, elytra and abdo- 

 men rufocastaneous, the tip of latter rufescent but not strongly set 

 off from rest. Head quadrate, posterior angles marked by ridges, 

 eyes at one-half more than their length from base; in front with a 

 strong median longitudinal impression, about half as long as head; 

 with large impressed punctures scattered not very sparsely at sides; 

 with fine strigulose ground sculpture. Pronotum about one-sixth 

 longer than wide, widest at anterior angles and arcuately narrowed 

 to rounded basal angles; discal series with five punctures, and with 

 about seven lateral punctures. Elytra with moderate punctures sepa- 

 rated by about their diameter but often indistinct and with intervals 

 forming indefinite transverse ridges; surface finely coriaceous. 

 Abdomen with fine and not very sparse punctures, generally sub- 

 muricate; with very fine strigulose ground sculpture. Male., un- 

 known. Female., eighth sternite truncate. Lengtli, 5% wi^n- 



Type locality. — Trinidad, one-half mile south-southwest of Man- 

 zanilla junction on the Plum Road. 



Types. — Holotype and paratype, females, U.S.N.M. No. 52464, col- 

 lected by me on December 18, 1935. Tlie paratype was taken at Sans 

 Souci on December 15, 1935. 



Records. — The following are the records known to me : 



Trinidad: Manzanilla (Blaekwelder station 102), Sans Souci (Blackwelder 

 station 98B). 



Specimens examined. — I have seen only the two types. 



Remarks. — This species is distinguished by its very much de- 

 pressed form, by its quadrate head, and by the arcuate sides of the 

 pronotum. 



The types were taken in rotting cocoa pods. 



16. BELONUCHUS ANTIGUAE, new species 



Description. — Rufotestaceous throughout. Head not narrowed be- 

 hind eyes but broadly rounded from eyes to neck ; eyes separated from 

 base by a little more than their length ; in front with a longitudinal 

 median impression about one-third as long as head ; with rather large 

 impressed punctures scattered sparsely at sides; with very fine strigu- 

 lose ground sculpture. Pronotum about as wide as long, widest in 

 front, sinuately narrowed posteriorly to rounded basal angles; dorsal 

 series with five punctures, and with about six lateral puctures; with 

 ground sculpture as on head. Elytra with moderate punctures fre- 

 quently individually indistinct because of uneven surface, often ar- 

 ranged in transverse rows; without ground sculpture. Abdomen 

 moderately sparsely and finely punctate, submuricately or excavately; 

 without distinct ground sculpture but somewhat iridescent. Male^
