 making this part convex on the outside and concave on the side towards the base. 

 • The ajjical portion of the wing is dark red, changing to bright ocher-yellow inwardly, 

 and tov-ards the aual angle divided by a subtemiinal geminate broken line of silvery 

 scales, extending from the costa to the anal angle. 



Fringe roddish-purple. The costa from the basal patch to the terminal band is 

 marked with geminate -white spots, altercating with gray. 



Posterior femora and tibiae very light siikygray : fore and middle femora and tibiae

One Iclmeumonid parasite belougiug to the genus Cremastus has been 

 bred by us from this species. It was referred to Mr. E. T. Cresson, -who 

 characterizes it as follows : 



Cremastus eetiniae Cresson (u. sp.)- 



Male. — Head brown; face, orbits, clypeus, mandibles, and palju yellow ; middle of 

 face clouded with fulvous ; antennae long and slender, black, scape beneath dull ful- 

 vous; thorax dull yellowish-brov/n ; lobes of mesothorax darker medially ; pro thorax 

 yellow ; scutellum dull yellowish ; metathorax black, .the flanks shatling into brown, 

 .the elevated lines well developed ; tegulae yellow ; wings hyaline, iridiscent; stigma 

 large, and with the nervures fuscous ; legs yellowish, varied with brown, especially 

 the posterior pair, tho tips of whose tibiae are blackish ; abdomen, with the two basal 

 segments, black above, yellow beneath, tho remaining segments reddish, with a black 

 spot at base abdve. Length .25 inch. 



Hah. — Ithaca, N. Y. Parasitic upon Eeiinla rigidana Fernald, a Tortricid. 



THE PINE LEAF MINEE. 



(GelecMa j)inifoliella Ch£(mbers [new species].) 

 Order Lepidoptera ; family Tineidae. 



Mining the leaves of difterent species of pine, a, minute, brown, narrow, cyUndrioal 



larva. (Plate V, fig. 6.-) 



For several years the leaves of the common x)itch pine {Finus-rigida) 

 in the vicinity of Ithaca, N. Y., have been seen to be extensively mined 

 by the larvae of a Tineid, the life history of which we have first studied 

 the present season. The end of the leaf, and in many cases the entire 

 leaf above its base, becomes dead and brown, and when opened it is 

 found to be entirely eaten out, and to contain, in the proper season, the 

 larva or pupa of the above-mentioned insect. 



What are in all probability the eggs of this insect have been found 

 deposited singly near the base of the leaves. They are nearly round, 

 flattened on the side of attachment, and slightly so on the opposite side. 

 Their average diameter is .14""° (.05 inch). The general color is red- 

 dish brown, differing in intensity with the stage of development. The 

 surface of each egg is marked with numerous delicate carinae, which 

 meet at the center, somewhat resembling those of the cotton and boll 

 worms figured in the article on cotton insects. AVe have not proof posi- 

 tive thatr these are the eggs of this leaf miner, but their size, appearance, 

 and place of deposit .^eer;is to indicate that they are. 



The work of the growing larvae is well shown in the plate, and also 

 the larva itself, highly magnified. From a study of the mines the larva 

 appears to burrow towards the end of the leaf first. Should it arrive 

 at the end of the leaf (and it almost invariably does) before attaining
