with central black murks; disc of tlie thorax, a little darker, with scat- 

 tered black scales.

 it is somewhat rubbed. Legs, colored like the body; inward surface of 

 anterior femora, distinctly ochraceous. Exp. % , 2.50 inches. Length

It is possible, that among the species of HaUsidota described by Mr. 

 Walker in the British Museum Lists, more material belonging to this 

 genus will be found. From the descriptions, the species cannot be re- 

 ferred to any of these. 



PARETJCILffiTES, nov. gen. 



The Cuban species ditl'er from Euclisetes ecjle, in the closer, more 

 sparse squammation, which becomes sub-diaphanous on the secondaries. 

 The ueuration very nearly agrees; the secondaries are hardly so full, 

 the internal nervures more propinquitous. The head and thoracic 

 parts are more finely scaled. Head wider behind, more prominent; 

 palpi smaller, not exceeding the front. The fringes on the wings are 

 shorter than in E. egle. The distinctional characters that I have ob- 

 served seem to warrant the erection of the new genus. 



Pareuchsetes cada-verosa. nov. sp. 



Pale dull yellow. Primaries, pale dull yellow, immaculate above and 

 beneath. Secondaries, paler than the primaries, immaculate above and 

 beneath, sub-diaphanous. Body, closely scaled. Head, with a more 

 ochreous shade. Prothoracic pieces, tegulas and thorax, concolorous 

 with primaries. Abdomen of a deeper, more ochreous yellow; a dorsal 

 segmentary series of dark brownish spots. A single reduced lateral 

 series of spots. Beneath much paler. T/nder thoracic surface and 

 legs, yellowish. Tarsi and anterior and middle tibiai, brownish. An- 

 tennte brown, with stout, short pectinations, produced from the under 

 surface. In the female the pectinations are shorter, but quite distinct. 

 Four specimens ( S S 9 ? ). Exp. S, 1.30 to 140, 9 1.40 inch. 

 Length of body, S and $ , 0.(50 inch.
