INSECTS INJURING CHESTNUT LEAVES. 349 



Larva. — Body very thick, of the same diameter throughout. Head somewhat 

 notched, not so wide as the body, pearl colored, spotted with dark irregular oblong- 

 oval spots. Body striped with livid and bright flesh-colored bauds, edged with 

 black. Supra-anal plate large, triangular, with four black tubercles; legs rather 

 large aud broad. Across the prothoracic segment is a row of from four to six black 

 jiiliferous shining black tubercles, with long, large, black hairs, and on each of the 

 two succeeding segments is a row of ten such tubercles. On each abdominal seg- 

 ment are two rows of such tubercles, those of the hinder row the largest, aud four of 

 them arranged dorsally in a trapezoid. On each side of each segment is a clear car- 

 neous patch, bearing four black piliferous tubercles. Length, 36 to 38""™. 



14. Tortrix f sp. 



This leaf roller was beaten from the chestnut at Providence, and on 

 September 18 spun a slight cocoon in a web. 



Larva. — Body light chestnut-brown. Head broad, marked with black dots; no 

 thoracic shield. The body tapers a little from the thoracic segments to the tail. On 

 each side of the back is a distinct black dorsal stripe. On the side above and be- 

 low the spiracles is a faint very narrow dark line. The segments much wrinkled ; 

 a large median wrinkle divides the dorsal part of the segment into two areas, on each 

 of which is a small black tubercle, giving rise to a brown hair. Length, 20™™. 



15. BuccuJatrix trifasciella Clem. 



The cocoonet of this species was found on the leaf of a chestnut tree 

 early in July. The cocoon is elongated, ribbed externally, and dark 

 gray. The imago appeared in the latter part of July. (Clemens.) 



Moth. — Fore-wings ocherous, with three silvery equidistant costal streaks, the 

 tirst near the base, the last at the beginning of the apical cilia, with the spaces be- 

 tween them somewhat darker than the general hue. On the middle of the dorsal 

 margin is a spot of blackish brown, with a patch of dispersed scales of the same hue 

 exterior to it, limited externally by a silvery dorsal streak. At the extreme tip is a 

 small blackish-brown spot, with an intercilial line of the same hue exterior to it. 

 Cilia ocherous. Hind wings fuscous, cilia the same. Antennae fnscoas. Head 

 ocherous; eye-caps somewhat silvery white. (Clemens.) 



16. Nepticula latifasciella Clemens. 



Moth. — Face pale rusty-yellowish; vertex dark brown; palpi and basal joint of 

 antennae (eye-cap), thorax, a broad fascia about the middle of the fore-wings, and 

 the cilia silvery white, tinged with pale yellowish (except the cilia). The tuft is 

 rather small; the antennae are pale, grayish fuscous, tinged with silvery; the fascia 

 is very hard, nearly straight on its anterior and convex on its posterior margin; the 

 costal cilia are fuscous; upper surface of abdomen fuscous, lower pale grayish fus- 

 <;ous, aud the legs darker fuscous. Alar expansion, 2 lines. 



As will be evident on comparison of this description with that of N. 

 nigriserticella Chamb. in Cin. Quar. Jour. Sci., ii, 118, there are many 

 points of close resemblance between them, although they are very dis- 

 tinct species. It was taken resting on the trunks of chestnut trees 

 {Gastanea americana), the leaves of which were full of empty Nepticula 

 mines about the middle of August. Kentucky. (Chambers, Bull. 

 U. S. Geol. Surv., iv, i, p. 106.)
