 the word "type" by Smith himself, and the other 

 specimens are unmistakably the types of the other castes.

LIV. — i\'e?^ Species of the Genus Platamops, Reitt. 

 [zrSpithobates, Champ.'\ [Cohoptera), from Tropical 

 South America. By G. C. CHAMPION, F.Z.S. 



The genus Platamop)s/u\c\\x^\r\^ two species from Colombia, 

 was described by Reitter* (1878) as a Cucnjid, and said to 

 liave simple, 5-jointed tarsi, witli a feebly lobed third joint. 

 There can be no doubt, however, from the other characters 

 given, that his definition of the tarsi was inaccurate (possibly 

 he did not examine the posterior pair, or they were missing- 

 in his types), and that Plnfamops is synonymous witii the 

 Pythid-genus Spithobates, Champ, f (1889), also based upon 

 two Tropical American forms. The four species now added, 

 one from Colombia and three from Brazil, are all contained 

 in the British Museum. These insects have the tarsi 5-, 5-, 

 4-jointed in both sexes, and the ante-penultimate joint a 

 little stouter than the minute penultimate one ; the anterior 

 coxal cavities open behind ; tlie prothorax with four or five 

 setigerous tubercles along the lateral margin ; and the elytra 

 clothed with intermixed long, erect, tactile set* and decum- 

 bent hairs. The general facies is very like that of the 

 ('Ucujid genera Tele/Jianus and Cryptamorphn^ and this 

 doubtless deceived the Austrian author, who compared 

 Flutamops with Plaianius, Er., and Parahi-oides^ Redt., 

 whereas the affinity with the Pythid-genus Salpingus^ Gyll. 

 (Spkcerientes, Steph.), is obvious. Tlie species here described 

 have six of the outer antennal joints widened, as in tl»e 

 P. {Spithobates) setosus, Champ., from Chiriqui, the three 

 terminal joints only being thickened in the Central American
