PELECOPSELAPHTTS. 3 



agrees with the former in the punctuation of the ahdomen ; the elytra, however, are 

 without the golden spots. I think, nevertheless, they undoubtedly belong to the same 

 species. 



" PELECOPSELAPHUS. 



Pelecopselaphus, Solier, Aim. Soc. Ent. Fr. 1833, p. 286. 



The species of this genus are chiefly from Central America and the Amazons. There 

 is, however, a single specimen of P. angularis, Schonh., in the British Museum from 

 Monte Video. The species are easily distinguished from Chrysesthes by their narrow 

 tarsi. 



1. Pelecopselaphus chevrolatii. (Tab. I. fig. 5, 5 a.) 



Pelecopselaphus chevrolatii, E. Saunders, Cist. Ent. i. 1874, p. 226 \ 



Hab. British Honduras (Blancaneaux) ; Nicaragua, Chontales 1 (Belt). 



2. Pelecopselaphus frontalis. (Tab. I. fig. 5, b). 



Mtidus, subtus cupreo-aeneus ; fronte cupreo-aurea, creberrime fortiter punctata ; thorace nigro-aeneo, fortiter 

 punctato, lateribus cupreo tinctis ; elytris cyaneo-seneis, plaga obliqua sub humero, macula laterali ante 

 apicem apiceque obscure purpureis ; pedibus nigro-cyaneis. 



Long. 6 lin. 



Hab. Nicaragua, Chontales (Belt). 



This species is close to P. chevrolatii, but is narrower; the forehead is more closely 

 punctured ; the thorax is more conical in outline, not dilated at the posterior angles, 

 without any lateral impression, and with less distinct purple margins. When viewed 

 from the side the lateral line is more oblique anteriorly, not turned down suddenly as 

 in P. chevrolatii. The elytra are similarly marked, but the coloration and the spots are 

 altogether less bright ; the punctuation is the same. 



3. Pelecopselaphus curtus. 



Pelecopselaphus curtus, Thomson, Typi Bupr. 1878, p. 25. 



Hob. Mexico (Salle). 



Three examples named P. curtus, Th., from M. Salle's collection only differ from 

 P. frontalis in having the posterior angles of the thorax slightly enlarged, and in 

 having the legs rather aeneous. Whether these are referable to the species named 

 P. curtus by Thomson I am unable to say ; for, although he observes that it is a species 

 " bien distincte de toutes les autres par les caracteres ci-dessus," I see nothing in those 

 characters to enable me to say whether his description refers to my P. frontalis or the 

 specimens named P. curtus from M. Salle's collection, or any other of the shorter species. 



4. Pelecopselaphus acutus. (Tab. I. fig. 5 c.) 



Pelecopselaphus acutus, E. Saunders, Cist. Ent. i. 1874, p. 226 \ 



Hab. Guatemala, El Heposo (Champion) ; Nicaragua 1 (Salle): P An am a 1 (Brit. Mus.).
