amongst them are shorter hairs tipped with a white knob, flattened and 

 nearly oval. The sides of the body, or rather the lateral edges, are fringed 

 with many of these shorter, clubbed hairs, which lie flat on the plane of po- 

 sition. On the penultimate segment is a dorsal, short, conical tubercle, des- 

 titute of hairs, as is the greater part of the upper surface. Upon the edges 

 of the under side, particularly in the wrinkles, are numerous short hairs, 

 like scales, which lie very thick together and are of a yellow, satiny lustre. 



Gastropacha velleda Stoll. 



Aug. 24, 1841. Found on cherry tree. Length when at rest one inch 

 and three fourths, in motion two inches. Gray above (in consequence of 

 the fine, close, blackish dots with which the surface is covered), and with 

 slender, wrinkled, longitudinal, white lines. A whitish band across the fourth 

 ring, immediately behind a concealed, velvet, black band on the top of 

 the third ring; and a whitish spot on the eighth and on the tenth rings. 

 Sides of each segment with a long horizontal tubercle just above the legs; the 

 tubercles furnishing spreading tufts of horizontal black hairs, intermingled 

 with a few white ones which end with a little flattened knob; the hairs 

 forming a fringe on each side of the body. First segment with a shorter tu- 

 bercle just above the long one on each side. Each of the following rings 

 with two dorsal warts, those on the top of the third ring, before the 

 transverse opening, very prominent, and of a dark rust color. Body be- 

 neath naked, orange colored, with a black spot in the middle of each i-ing. 

 First six legs pale rust colored, the others ashen. 



N. B. The prominent single tubercle found on the top of the eleventh 

 riu"- in some other lappet caterpillars is wanting in the above, there being 

 only two small warts, as on the other rings.
