the middle. Legs simple, rather short and tolerably robust, the poste- 

 rior pair the longest and stoutest ; posterior coxfe elongate, almost as 

 lono- as the femora, which are short and somewhat thickened ; tibial 

 spurs moderate ; tarsi slender, claws very robust, curved and acute at 

 tip, pulvuli large. Abdomen ($. Fig. 1, c) petiolated, very long, 

 slender, strongly arcuated beyond the basal segment which is one-third 

 the length of the abdomen, slender, linear, recurved towards the tip, 

 with a subobsolete tubercle on each side of the middle, tip slightly di- 

 lated ; 2nd and following segments gradually shorter and broader, the 

 apex faintly subcompressed, truncate in the % ; beneath, the tip is sUt 

 longitudinally in the $ , the ovipositor about as long as the 1st segment 

 of the abdomen. 



This singular genus may be easily recognized by the elongate, flat- 

 tened thorax being unusually produced before the wings; the long and 

 narrow wings, the situation of the stigma and areolet unusually near the 

 tip of the wings, and the long, slender, arcuated abdomen, and its long, 

 cylindrical, recurved basal segment. 



It gives me pleasure to dedicate this interesting genus to my friend 

 and fellow student, Mr. Augustus R. Grote, the distinguished American 

 lepidopterist, by whose zealous endeavors the Collection of the Entomo- 

 logical Society is being constantly increased.

 distinct, longitudinal, central, yellowish lines, the lateral sutures black- 

 ish; scutellum yellow, as well as the postscutellum ; metathorax highly
