13 1 THIRD ANNUAL REPORT OF 



the Peach than on any other tree, and as it appears very early in the- 

 season and commences to feed on the young leaves before they are 

 fully expanded, it does considerable damage when numerous. 1 have 

 been acquainted with the worm for several years past but its natural 

 history was unknown till last summer when Dr. LeBaron and myself 

 simultaneously bred the moth from peach-leaf fe< ding larvse, so that 

 its history is now given for the first time. Figures of the larva were 

 given in the Prairie Farmer last summer by Dr. LeBaron who was; 

 misled by Dr. Hull into the belief that they were the Tent-caterpillar 

 of the Forest already described. Two years ago I found this Blue- 

 spangled worm tolerably common in the peach orchard of Mr. E. J. 

 Ayres of Villa Ridge, Ills., and he says that he destroyed over a thou- 

 sand of them last spring. In this State I have frequently met with 

 it but it is by no means common. Hand picking will easily keep it 

 in check. 



CALLnroRPHA fulvicosta, Clem.— Larva (Fig. 56, a)— Color velvety-Black above, rale bluisli- 

 gray speckled with black below. A deep orange medio-dorsaf line (usually obsolete towards each 

 end) and a more distinct, wavy, broken, yellow stigmatal line, with a less distinct coincident pale- 

 line below it. Covered with large highly polished, roughened, deep steel-blue warts, the irregu- 

 larities of which as they catch and reflect the light, look like pale blue diamonds. Closely ex- 

 amined these warts are found to be covered with small elevations each of which furnishes a short 

 stiff yellow hair, these hairs radiating in all directions around the warts, which are placed as fol- 

 lows : —Joint 1 with an anterior transverse row of 3 and a posterior dorsal row of 4 ;. joints 2 and 

 3 each with a transverse row of 8 across the middle ;. joints 4 — 11 inclusive, each with 4 circular 

 ones anteriorly, and 2 irregular ones posteriorly on dorsum (Fig. 56 d, each of the last evidently 

 formed by the blending of two), and 2 on each side near the middle of joint (Fig. 56 e). Joint 12" 

 with 2 that are irregular, on the back, and 1 that is circular, on each side. Anal shield formed of 

 one large irregular wart. In addition to these there is a narrow subventral wart each side, and 2 

 small ventral ones on the legless joints. Head polished black with a few black hairs. Thoracic- 

 legs polished black, but pale at the joints inside : prolegs black outside, flesh-colored within and' 

 at extremities. Stigmata not perceptible. Largest in the middle of body. Average length 0.90,.. 

 greatest diameter 0.15 inch. 



Described from 6 peach-feeding specimens. Alcoholic specimens do not reflect the pale blue- 

 points. 



The larvse of our different CalHmorphas seem to bear a very closeresemblance to each other. I 

 have bred C. chjinene, Ilubner, from a larva. found full grown on eak (tho' whether it fed on oak I 

 did not ascertain) which so resembled that of fulvico&ta that I fully expected it would produce 

 nothing else. The only difference noticeable was that it was very bright colored, with the medio- 

 dbrsal line very clear and distinct. Mr. W"m. Saunders lias reared C. LcC'ontci from larva 1 feeding 

 on Horse Gentian {Triosteum prrfoliatum), and from his description of the larva* it differs prin 

 cipally from the above in lacking the blue reflections and in having a pale dotted subdorsal line. 



THE ASH-GRAY PINION— Xylina cinerea, K. sp, 



(Lepidoprera, Xyliuid;v). 



There is a pale green worm with cream-colored spots and a broad! 

 cream-colored lateral band, which I have for several years known to
