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

 specimens are unmistakably the types of the other castes.

LIV. — New Species of the Genus Platamops, Beitt. 

 [=Spithobates, Champ.'] {Cohoptera), from Tropical 

 South America. By G. C!. CllAMPION, F.Z.S. 



The geiuis P/a^awjojt?.<f^includino; two sjiecies from Colombia, 

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

 have simple, 5-jointed tarsi, with a feebly lobed third joint. 

 There can be no doubt, however, from the otlier 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 Phitamops is synonymous with tlie 

 Pythid-genus Spilhobates, Champ, t (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 elj-tra 

 clotlied with intermixed long, erect, tactile setae and decum- 

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

 (yiicujid genera Telephanus and Cryptamorpha^ and this 

 doubtless deceived the Austrian author, who compared 

 Phitamops with Platatnus, Er., and Parahro7ites, Redt., 

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

 (Sphceriestes, Steph.), is obvious. The species here described 

 have six of the outer antennal joints widened, as in the 

 P, (^Spithobates) setosiis, Cliamp., from Chiriqui, the three 

 terminal joints only being thickened in the Central American
