NOTES ON TROPICAL AMERICAN LAGRIIDAE, WITH DESCRIPTIONS 

 OF NEW SPECIES. 



BY G. C. CHAMPION, F.Z.S. 



(Plate II.) 



These " Notes " are the result of a critical examination of various 

 species of the genera CoJparthrum, Disema, Jfeniscophonts, Uropl«- 

 topsis, etc., contained in the British Museum, mainly derived from the 

 Fry and Bates collections, supplemented by a few insects belonging to 

 the Oxford Museum. The great genus Statira, 89 species of which from 

 Central America were enumerated in the ' Biologia ' in 1889-1893, has 

 been similarly dealt with in a paper recently communicated to the Ento- 

 mological Society of London.* The identification of the sexes, to which 

 especial attention has been paid, has resulted in the discovery of important 

 specific chai'acters in not a few of these insects.

Fourteen species are added to this Tropical American genus, two of 

 these having been described by Maklin under Statira. Kii-sch's Colombian 

 type, C. gerstdcJceri, is still iinknown to me. Five have been recorded 

 from Central America. Amongst those here emuuerated, the tridentate 

 mandibles have been examined in C. decoratum (figured in the 

 *JMo\og\a,''^, fasciatinn, apicale, reedi, JJavosellatum, and nigricauda ; 

 the apical joint of the labial palpi is sublunate or triangular in all of 

 them. In C. spinicauda the elytra are mucronate at the tip, as in 

 C calearatum Champ. C. suhsignatiim has a faint opaque patch towards 

 the sides of the elytra beyond the middle, and, therefore, may have to 

 be removed from Colparthrtim when more specimens are available for 

 examination.
