\ 



Possibly identical with the preceding ; it comes better with Pachygonia than with Peri- 

 gonia, although it may eventually have to be placed with P. coffcece in a new genus. 



Genus 11. Ehodosoma, n. gen. 



Allied to Perigonia. Primaries elongate, triangular. Secondaries subtriangular, 

 rounded at apex, subangulated at anal angle. Discocellulars of all the wings convex. 

 Discoidal cell of secondaries very short. Head small. Palpi obtuse, conical in front. An- 

 tenna? long and slender. Thorax and abdomen very robust ; the latter compressed, trun- 

 cate behind, with small lateral and terminal tufts. Tibiae of second and third pairs of 

 legs terminating in two strong diverging spines. 



Type R. triopus. 



Rhodosoma teiopus.
