anal segment with a dorsal jet black tuft, covered on each side by a longer, 

 incurved, black pencil ; no lateral pencils. 



The short dorsal tufts are jet black. The pencils are of a black color, 

 not nearly so intense. 



Lophocampa carysB Harr. 



Caterpillar found on the nut tree {Carya porcina), Oct. 1, 1827. 

 Body above white, beneath cinereous, head and corneous feet polished 

 black ; fourth to eleventh dorsal segments, with transverse series of fan- 

 shaped tufts of black and white hairs, the central being black (so that the 

 insect appears to have eight black spots in a series on the back) ; sides and 

 anterior and posterior segments tuberculate, and with Avhite fascicles; 

 tburth segment with two elongated black tufts or pencils, eleventh * with 

 lour pencils of black hairs. Rolls up when touched. Cocoon sirajily formed 

 of hairs. Shape oblong oval. Moth came out June 1, 1828. 



Aug. 28, 1838. On fences, fully grown. Body satin white above, dusky 

 beneath, head and true feet black, prolegs dusky; sides of the body spotted 

 with black, and with black tubercles emitting stellated or divaricating, 

 white hairs, the two dorsal series short, truncated, and converging, and of a 

 black color from the fourth to the eleventh segments inclusive ; two black 

 pencils on the fourth and tenth segments and a dorsal series of black 

 spots from the fourth to the eleventh segments ; on all these segments the 

 dorsal tubercles are In a double series, viz., two before, nearer together than 

 the others — one half of the hairs from Avhich are black, and converge in a 

 tuft on the back, and the other hairs are white ; two others more distant, 

 and furnishing only divaricating, white hairs. These four dorsal tubercles 

 are transverse, or very elongated (almost linear) oval; the tubercles on the 

 sides are hemispherical. The white hairs on the first three segments, and 

 on the two last, are longer than the rest; and those on the sides of the body 

 are longer than those on the back. The black pencils on the fourth and 

 tenth (not eleventh) segments, are longest of all. Ptolls up when touched. 



Sept. 18, 1840. Larva white, covered with white hairs in short spread- 

 ing tufts, a row of eight black tufts on the back, beginning on the fourth 

 segment; two long, black, pencil-like tufts on the fourth and tenth segments; 

 four white pencils on the second and third, and two on the eleventh and 

 twelfth segments. Head and prolegs black; the surface of the body with 

 minute black tubercles, and a transverse black line between each segment. 

 It varies in having the tufts of hairs each side of the dorsal black series 

 dusky. 



July 15, 1842. On the last leaf of a branch of Tilia americana, found 



* This is probably a mistake for tenth segment.
