Light cinnaniou bvowii. Palpi, prothorax, femora and tibiae and 

 secondaries a little darker. On the primaries the costo-median region is 

 filled in with a large dark tan colored triangular spot, its apex sometimes 

 rounded, terminating a little beyond the submedian nervure. It is 

 continued along the costa to the base of the wing, and terminates 

 sharply upon the apex. Externally it is lined with silver. A discoi- 

 dal dark discoloration. Beneath concolorous with the upper side of 

 the secondaries, a little darker at the apex. The body is stouter than 

 in the other species, while the head is hardly so prominent. The costa 

 of the primaries, which is straight, becomes a little convex towards the 

 apex, hence the apical interspace is a little broader and shorter than 

 usual. The internal angle is not so well marked as in the other spe- 

 cies. 



Mr. ShurtleflF has reared this species from the larva which he found 

 under a maple tree, and has thus enabled me to identify it with Harris' 

 species. According to his description the larva is green, spotted above 

 with brown ; pale beneath. The sides were raised and the dorsal sur- 

 face flattened. It constructed a dense obtusely cylindrical ovate cocoon 

 on the surface of the ground, Oct. 17. It was surrounded by an outer 

 thin envelop, covered with grains of sand. The moth appeared June 15. 



Limacodes biguttata n. sp. 



Of a soft velvety buff-brown. A whitish line reaches from the mid- 

 dle of the internal margin across and outward on to the middle line. 

 A short corresponding one from near the costa goes to the middle of 

 the outer margin, thus making an inverted broad ^ (y) inclosing at 

 the internal angle a roundish red spot. Apex red. Secondaries and 

 beneath uniform obscure buff-brown. It is a soft, woolly, velvety spe- 

 cies, thickly scaled, covering over the nervures.

9 . Testaceous yellow. Primaries with brown lines reaching from 

 the inner third of the internal margin to just beyond the middle of the 

 costa, with a second one parallel to it, but interrupted in the middle of 

 the wing by a third line which arises half way on the costa between
