except seven spots on eacli elytron, which have black pubescence. 

 These spots are placed — one on the shoulder and reaching to the scu- 

 tellum ; the second and third on the margin, conical, one near the 

 middle and the other sub-apical ; the fourth just below the scutellum ; 

 the fifth between this and the central lateral one ; the sixth next the 

 suture, round, rather below the middle ; the seventh round, apical. 

 Abdomen reddish-brown, thickly and finely punctured, and clothed 

 with fulvous pubescence. Pygidium light reddish-brown, clothed with 

 fulvous pubescence, and thickly punctured in the male, without pu- 

 bescence, and with a few small tubercles irregularly placed, in the 

 female. The sternum slightly tinged with seneous. Legs black, the 

 femora slightly seneous. 



The male specimen has the fourth and fifth spots on the elytra 

 confluent.

DESCRIPTION OP A NEW GENUS AND SPECIES OF SATYEIDIAN 

 BUTTERFLIES. 



BY AETHUB G. BUTLEE, F.L.S. 



Among the many highly interesting and remarkable insects 

 recently brought home from Chili by Mr. Edwyn C. Reed, is a very 

 beautiful new form belonging to the sub-family Satyrince, which, as it 

 differs considerably from all the genera of that sub-family in struc- 

 ture, I propose to make the type of a new genus, characterized as 

 follows : — 



STIBOMOEPHA, g. n. 

 Wings broad, coarsely scaled ; primaries of the same form and neu- 

 ration as in Tetraphlehia, but slightly broader, and the veins consequently 

 wider apart : secondaries, costa distinctly arched ; outer margin very 

 feebly arched and scalloped, with fringe very long ; inner margin undu- 

 lated, distinctly excavated above anal angle ; neuration somewhat similar 

 to that of Tetraplilebia, but the veins wider apart, the sub-costal nervules 

 emitted closer together, and the relative lengths of the discocellulars 

 reversed (the lower being about four times the length of the upper, 

 running sub-parallel to the discoidal nervure for half its length, and 

 then diverging very obliquely to the origin of the third median ner- 

 vule) ; palpi slender and long, longer than in TetrapMehia, and less 

 hairy ; eyes comparatively smaller ; antennae imperfect in the type.
