HICKORY CATERPILLARS. 309 



broad greenish-yellow median band, ending before reaching mesothoracic or posteri- 

 orly the eighth abdominal segment. The ninth and tenth segments greenish yellow, 

 including the anal legs. Prothoracic segment yellowish above, interrupted by a 

 median short, broad, black band. Prothoracic and mesothoracic segments with ob- 

 lique yellowish-brown bands extending to the feet. Length, 25™"*. 



70. Noctuid^ caterpillar. 

 (PI, XXV, Fig. 2.) 



For several-years I have noticed a greenish . semi-looping caterpillar 

 on the hickory eating large holes in the leaves. In one year they 

 were very abundant. They appear as soon as the leaves begin to 

 unfold, and ^et their growth by June 15 to 20, when they fall to the 

 ground and pupate. The year in which so many were observed, large 

 numbers were ichneumoned, many caterpillars having an egg aflBxed to 

 the head. (Fig. 2.) Whether from generally being ichneumoned, or 

 sickly in confinement, after repeated attempts we have failed to rear 

 this common caterpillar. 



Larva. — Body of moderate thickness ; head smooth, not lobed, not quite so wide as 

 the prothoracic segment. Pea-green, of the hue of the under side of a leaf. Spiracles 

 dark. Two subdorsal white lines and below two narrower ones on each side, six in 

 all, one above and one below the spiracles. Length 19™™. 



71. Pbycis rubrifaseiella (Packard). 



Family Pyralid^ ; order Lepidoptera. 



This insect mines the recently expanded leaves and partially 

 expanded large buds of Carya glabra and another species with seven 

 leaflets, probably amara, making a mass of "frass" under the revolute 

 outer bracts, also boring into and hiding in the base of the leaf stalks. 

 It occurs in abundance on Carya amara ? in Providence May 25, or 

 before the trees are wholly leaved out. It pupated June 1, 2. In one 

 case the caterpillar pupated June 8 and the moth appeared early in 

 July. June 14 other larvte were found mining in the stems of the 

 leaves, building out the mouths of the mines with tubes formed of ex- 

 crement, and making a tent of the leaflets. 



Larva. — A reddish-brown caterpillar, with the body thick and fleshy, tapering sud- 

 denly toward the head and tail ; head and prothoracic shield chestnut-brown. Head 

 narrow, much narrower than the prothoracic shield. Thoracic feet dark brown. In 

 the abdominal segments the posterior half of the back is separated from the rest by 

 a deep distinct suture. Piliferous dots minute, with sparse, rather long hairs. 

 Supr%-anal plate small, rounded. Length 12™™. 



Pupa. — Of the usual brown color, the end of the abdomen much rounded, pro- 

 jecting from a transverse supra-anal projecting ridge, with the usual stift' curved setae 

 unusually small and short, from six to ten placed irregularly ; in one pupa only six 

 large and well marked, in another eight large ones and two small ones, and scattered 

 in position ; in size and situation very different from the pupa of P. contatella and 

 that of another species, on Gleditschia. 



Moth. — Antennie of male with the usual tuft on basal joint; the palpi slender, 

 pointed, ascending vertically. Body and fore-wings slate-ash, glistening; thorax
