REPORT OF THE ENTOMOLOGIST. 213 



unless through parasites, owing to the numerous food-plants of this in- 

 sect. Is'^o matter how the work of destruction is performed upon the 

 apple, the trees will be restocked from the wild cherrj' or some other 

 plant difficult to reach. 



We append a description of the larva and chrysalis, and quote Dr. 

 Clemens's description of the adult, to enable readers to recognize the 

 insect. 



ASPIDISCA SPLENDOKIFEKELLA Clem. 



Adult. — Head golden. Antennae fnsoous, tinged witli golden. Fore-wings, from 

 tlie base to the middle, leaden gray,* with a splendent lustre, and from the middle to 

 the tip golden, with a broad, nearly straight, metallic silvery streak extending from 

 the costa near the tip to the middle of the wing, and dark margined on both sides. 

 This is nearly joined by a dorsal streak of the same hue almost opposite to it, with con- 

 verging dark margins," and with a blotch of dark-brown scales adjoining it behind. 

 In the costo-apicai cilia is a short, blackish-brown streak parallel to the dark margin 

 of the silvery costal streak. At the tip is a black apical spot, with metallic silvery 

 scales in its center, and a few silvery scales in the cilia above and beneath it. A 

 blackish-brown hinder marginal line in the cilia, interrupted by a silvery streak in 

 the cilia beneath the apical spot, and the cilia yellowish-bro\vn. Hind-wings leaden 

 gray ; cilia yellowish-brown. 



Full-grown mining larva. — Length 3""" (.12 inch). Head small, short, oval, retrac- 

 tile. First thoracic segment twice as wide as head ; widest behind, rounding to base 

 of head. Second thoracic segment wider than first, but only two-thii"ds as broad. 

 Third thoracic segment narrower than second ; succeeding segments gradually dimin- 

 ishing in size. General color light yellowish-brown. Head dark ; first thoracic seg- 

 ment with a broad brownish disk, leaving a narrow yellowish band around border; 

 second and third thoracic segments each with a similar brown disk, with two large 

 transversely-oval yellow spots; abdominal segments 1 to 6 have each an irregular 

 brown spot in the middle. No true legs present. The oval yellow spots on the sec- 

 ond and third thoracic segments are cup-like depressions, dorsal and ventral, which aid 

 in locomotion. There are also strongly-marked integumental folds laterally and at the 

 anus, which act as prolegs. Projecting laterally from each of the thoracic segments 

 are four hairs, two on each side ; and from each abdominal segment except the last, 

 one projects on each side. Around the anus there are ten hairs, each springing from 

 a small tubercle. Joints of segments quite strongly marked. Upon the ventral side 

 of the prothoracic segment is a transverse slightly recurved row of from twenty to 

 twenty-five small pointed tubercles. 



Hibernating larva. — Length L7""» ; width .7""". Broad, stout, sides snbparallel ; ends 

 Bubequal. Head entirely retracted in prothoracic segment. Distinction between seg- 

 ments not nearly so marked as with mining foi-m. General color rich straw. The only 

 marking is a narrow brown curved line on the under side of the prothoracic segment. 

 No lateral hairs observable. 



Chrysalis. — Length 1.5""°. In profile the venter is straight and the dorsum con- 

 siderably arched. Wing-sheaths and posterior tarsal sheaths extending to end of 

 abdomen. Antennal sheaths short, ending nearly even with anterior tarsal sheaths. 

 Head more elongated and more strongly differentiated from thorax dorsally than is 

 usual. No spines of any kind observable. Color: Abdomen light-yellow, blackish at 

 anus; eyes large and black ; wing-covers, leg and antennal sheaths, dorsum of thorax, 

 and head smoky, darker on forehead than elsewhere. 



THE GRAPEYINE FLEA-BEETLE. 



Graptodera [Haltiea] cJialybea, Illiger. 

 Order Coleoptera; family Chrysomelidae. 



Eating into the buds in early spring, and, later, gnawing holes into the leaves, a small 

 steel-blue jumping beetle. In May and June the brown sluggish larvae upon the 

 upper surface, also eating irregular holes, and fi-equently skeletonizing the leaf. 



So much injury has been done by this celebrated pest during the past 

 season, and so little seems to be knov/n concerning its habits amongst 

 those of our correspondents who have been the worst afBicted by it, that 

 we feel constrained to give in brief a resume of its natural history, fig-
