transversely on the dorsal surface from the edges of which pro- 

 ject a few short whitish hairs, and from the central portions a few 

 stout, short black hairs. There are two similar tufts on the anal 

 segment. The remaining tufts are composed of long whitish 

 hairs, very thickly set on the anterior segments and projecting 

 forwards over head on seg. i. Form stout, shape much as in the 

 preceding species. L.4om. m. Cocoon between leaves or in rotten 

 bark. Found in September on apple, cherry, walnut, oak, linden 

 and ash. Easily recognized by the peculiar tufts. Rests by day 

 on the trunk of its food plant. 

 Apatela afflicta. Grote. 



Mature larva. Light yellow-brown, tinged with green, darker 

 superiorly. A few lateral whitish hairs. Stigmata white, ringed 

 with black. A whitish stigmatal line ; a distinct, continuous 

 black dorsal line. A sub-dorsal row of stiff club-shaped hairs, 

 such as are found in the larva of A. funeralis, but much smaller 

 and not noticeable. These are easily broken and in the speci- 

 men before me are present only on segs. 4, 5, 6 and 11, though in 

 more perfect specimens they may occur on all the segments. 

 One specimen found was rich yellow-green, and all vary consider- 

 ably in shade. Head yellow-brown, lighter externally, sparsely 

 clotlied with whitish hairs. Form stout, flattened posteriorly. 

 Rests with head touching the posterior segments, selecting a 

 withered or discolored leaf on which it is well concealed. Co- 

 coon stout, elongated, spun among bark. Several specimens on 

 red oak. Cocoon also under walnut. Spun September 17-25.
