REPORT OF THE ENTOMOLOGIST. 233 



fall, but rather that they Tvere the mines of an earlier brood. Hundreds 

 of mines have been opened durincj the months of January and February, 

 and the insect has never lieen found in any other than the pupa state, 

 and no hibernating motlis have l)eeu seen. 



Ir.asmucb, tlieu, as the insect hibernates in the pupa state within the 

 mines in the dead leaves, the remedy ia obviously the same as that 

 l)roposed for the ravages of L. liamadryadeUa. 



VVe here introduce detailed descriptions of the larva and pupa, as 

 those of Dr. Fitch were very incomplete, and quote Clemens's descrip- 

 tion of the adult, so that it will be possible for our readers to recognize 

 the insect in any of its stages. 



LlTlIOCOLLETIS FiTCHELLA Clem. 



Larra. — Length, wlien fiill-j^o-vrn, 4™™; ^idlli of first ilioracic segmcnf; .81"""; 

 6\ibcyliuclrical, flattened somewhat (lorso-ventrally ; head triangular, retractile; 1st 

 thoracic segraent largest, others suhequal, but tax)eriiig slightly to the end of the body. 

 When young the thoracic segments are much larger than abdominal segments. Color 

 creamy white, alimentary canal being dimly seen as a dark shade through the semi- 

 transparent in tegument ; tips of mandibles and thoracic tarsi brownish. 'J'horacic legs 

 strong and well developed ; 3 prop-legs, anal pair well developed, the first tliree jiairs 

 not w(;ll develoxied. Ko indicul ion of a horny prothoracic or anal plate. Whole upper 

 eni'face and sides of the body with sparse long white hairs. 



Pupa. — Average length 4.6"^'"; average breadth at stoutest part of body 1.09™"'. 

 General color pale yellow, with brownish tinge to wing covers and dorsum of thorax; 

 wing covers reaching to Ihe penultimate abdominal segment ; clypeus prolonged into 

 a strong but short forward-curved beak with smooth edges ; face with four short, 

 slender, excurved tentacles ; anal Eegment with four excurved hooks at tip. Eighth 

 adbominal segment with two semi-circular, incurved, longitudinal, homy ridges, ap- 

 proaching each other ventrally, and visible dorsally only as lateral prolongations of 

 the posterior border of the segment. From various x^arta of the abdomen issue long 

 white hairs, each hair arising from a definite tubercle. 



Imago. — "Head, face, and thorax silvery white. Labial palpi tipped with pale 

 ochreous. Antennae ])ale satfron; basal joint silvery white. Fore wiugs pale reddish 

 Baffron, with a sligin; brassy hue. Along the costsu are five silvery -white costal streaks, 

 all black-margined internally except the first, which is very oblique and continued 

 along the costa to the base f>f the wing. All the costal streaks are short except the 

 first. On the inner margin are two conspicuous silvo']; dorsal streaks, dark-margined in- 

 ternally, the first very large and placed near the middle of the inner margin, the sec- 

 ond opposite the third costal streak. At the tip is a small round black spot, placed 

 above the middle of the wing ; cilia silvery gray, tinted with saffron. Hind winga 

 grayish fuscous; cilia paler." 



EETINIA? COMSTOCKIAKA Fernald. 



Order LEriDOPTERA ; tamily Tortricidae. 



Boring into the twigs and small branches of the pitch-pine {Pinxis rigida), causing an 

 exudation of resin ; yellow-brown larvae, aboiit 10"™ (.39 inch) long, transforming 

 within the liurrow and giving forth small brown and gray moths. (Plate V, fig. 1.) 



An examination of the pitch-pines in the vicinity of Ithaca, IST. Y., in 

 the early part of the ]^ast summer, revealed the fact that they were in- 

 fested to a considerable extent by a heretofore undescribed pest. Upon 

 the smallest twigs and limbs and upon the terminal s])oots of the trees 

 were observed exiuling at intervals masses of pitch, mixed with the ex- 

 crementiil pellets of some larva. In most cases there were two distinct 

 layers of the resin to be seen, the lower dry, hard, whitish, weather- 

 beaten, having evidently been exposed during the winter, while the 

 upper mass was fresh, softer, and of a hoary, bluish color on the sur- 

 face, yellowi.sh beneath, having the appearance of a comi)ar.atively re- 

 cent exudation. These resinous laini>s, wlien occurring upon twigs or 

 limbs, were, in the great majority of cases, upon tlu) upper side, and
