150 MESSRS. GODMAN AND SALVIN ON [Feb. 18, 



series of prominent oblong tubercles. Heel without prominence. 

 Very dark-coloured, a more or less distinct small white spot on the 

 middle of the side ; each toe generally with a narrow white ring. 

 Two males, 10 inches long, the tail measuring exactly one half. 



3. Descriptions of new Species of Rhopalocera from Central 

 and South America. By F. DuCane GodmaNj F.Z.S., 

 and OsBERT Salvin, F.R.S. 



[Eeceived January 29, 1879.] 

 (Plate XIV.) 



The following descriptions are all taken from specimens in our col- 

 lection ; they relate to species many of which have long remained un- 

 named ; to these we have added descriptions of some recent acqui- 

 sitions. Figures of all the Central-American species will shortly be 

 published. 



EUTRESIS HYSPA. 



cJ . Exp. 3-9 in. Allied to E. hyperia, D. & H. (Gen. Diurn. Lep. 

 i. p. 112, Suppl. PI. f. 2) : but the primaries are diaphanous where in 

 E. hyperia they are fulvous ; the secondaries also are almost dia- 

 phanous, the inner edge of the dark margin, especially near the anal 

 angle, the spot at the end of the cell, and the nervules alone being 

 fulvous. To E. theope (nob. P. Z. S. 18/7, p. 60) it is more 

 nearly allied, differing chiefly in the broader margin of the second- 

 aries and the greater restriction of the fulvous on those wings. 



Hab. Ecuador, Jorge, Guadalquiza {Buckley). 



Athesis demylus. 



c? . Exp. 3 in. Nearly allied to Dircenna dercyllidas, Hew. 

 (Trans. Ent. Soc. ser. 3. ii. p. 248, pi. 1 6. f. 4), of which it is a more 

 southern race. The transverse markings of the primaries are very 

 narrow, the whole of the wing being diaphanous with the exception 

 of the dark margins, the remains of the transverse bands being re- 

 presented by the dark nervules. The transverse band of the secon- 

 daries is narrower, as well as the outer margin. 



Hab. Southern Ecuador. 



We have two male specimens of this species which were sent from 

 the confines of Ecuador and Peru some years ago. We have hesi- 

 tated to describe it before being convinced of the constancy of its 

 differential characters. 



Melin^a hxcetas. 



<S . Exp. 3-4 in. Allied to M. maelus (Hew. Ex. Lep., MecJia- 

 nites, t. 3. f. G), but differing in the absence of yellow in the cross 

 band of the primaries, this portion of the wing being of the same 

 colour as the base. The apex is black, enclosing three yellowish
