PARAGRYLLUS, Guer.-Men. 



Paragryllus, Guerin-Meneville, Icon, du Regn. Anim., Ins. p. 329 (1829-1838) ; Saussure, Miss. 

 Scient. Mex., Orthopt. pp. 430, 441 ; Melang. Orthopt. 6 e fasc. pp. 536, 551 (fig. xli., 1*). 



A very remarkable genus, on account of the complication of the tympanum of the 

 elytra of the males, and by the fact that the superior internal spur of the hind tibia 

 is tumid and enormously large in this sex (Tab. XII. fig. 5, c). Both sexes are 

 completely winged ; and the elytra of the males possess a well-developed unmodified 

 apical field. Their tambourine is characterized by numerous oblique veins and by a 

 rounded speculum divided by numerous arched nervures (Tab. XII. fig. 4). The 

 discoidal vein is fused at the base with the humeral vein (as in the genus Homceogryllus) ; 

 the medio-discoidal area is thus very fusiform, and also pointed at the tip. 



The Paragrylli were hitherto known only from the males. I here give the description 

 of the females of two species, showing that the enormous spur of the hind tibiae is 

 peculiar to the males, the females having normal spurs, the superior one being only 

 somewhat incrassated, but not abnormal. 



The genus is restricted to Tropical America. In addition to the two species 

 enumerated here, a third, P. martinii, Guer.-Menev., is known, from the island of 

 Guadeloupe.
