12, BELONUCHUS SATYRUS Erichson 



Belonuchus satyrus Ebichson, 1840, p. 421. — Uernhaueb and Schubert, 1914, 

 p. 371. 



Description. — Iridescent black, elytra and apex of abdomen rufo- 

 testaceous. Head straight at sides, with basal angles broadly 

 rounded ; eyes at about their length from base ; in front with a feeble 

 longitudinal impression extending nearly to middle; with only the 

 usual scattered large punctures; with very fine strigulose ground 

 sculpture. Pronotum scarcely wider than long, widest at anterior 

 angles, feebly narrowed posteriorly, basal angles completely rounded ; 

 discal series of five punctures, and with about five lateral punctures; 

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

 quently separated by less than their diameter and sometimes indis- 

 tinctly transversely serial; without ground sculpture. Abdomen 

 with moderately sparse submuricate punctures; without distinct 

 ground sculpture although vaguely alutaceous. Male, supraantennal 

 prominences strongly elevated; eighth sternite broadly and very 

 feebly emarginate. Female, supraantennal prominences not ele- 

 vated; eighth sternite rounded. Length, 10 to 12 mm. 



Type locality. — Colombia. 



Types. — Either in the Hope Museum, Oxford, or the Zoologische 

 Museum, Berlin. 



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



Trinidad: (Birch and Bryant, in British Museum; Busck, in U.S.N.M.), Man- 

 zanilla (Blackwelder stations 103A, 104A), Moruga (Blackwelder station 

 111), Sangre Grande (Blackwelder station lOOA), 



South America: Colombia (Erichson, 1840; British Museum), Colombia, Vene- 

 zuela, New Granada (Bernhauer and Schubert, 1914), 



Specimens examined. — I have seen 2 examples in the British Mu- 

 seum, 1 in the United States National Museum, and 10 collected by 

 me in 1935-37, 



Remarks. — This species is readily distinguished by its size and 

 color, as well as the development of the antennal ridges in the male. 



My specimens were all taken from cocoa pods (both freshly cut 

 and well decayed). 



13. BELONUCHUS DOMINICUS, new species 



Description. — Head piceous, pronotum piceocastaneous, elytra rufo- 

 castaneous, abdomen rufous. Head feebly narrowed behind the eyes, 

 sides rounded into base ; eyes at a little more than their length from 

 base ; in front with a longitudinal impression half as long as head ; with 

 rather coarse and impressed punctures scattered at sides; with fine 

 strigulose ground sculpture. Pronotum about one-tenth longer than
