FOURTH ANNUAL REPORT OF 



Pempelia * Haaimondi, N. Sp. Imacjo (Fig. 21, d).— Average expanse 0.48 inch. Front wings 

 glossy purplish-brown with two silvery gray ti-ansverse bands dividing the wing on costa in about 

 three equal parts, the basal band sharply defined outwardly and always extending to inner margin, 

 the posterior band never extending more than half way across the wing, and generally not more than 

 one-third, illy defined. In some specimens the basal transverse band is quite narrow, with the 

 basal space a shade paler than the median: in others the band forms a double line. In some speci- 

 mens also, a narrow pale transverse line outside the second baud, and a pale terminal shade, are 

 visible. Hind wings uniformly paler gray. Under surface glossy gray, with no marks, the front 

 wings a shade darker than the hind, cf difi'ers from Q in the basal portion of the antennfe being 

 curved, and the curve filled with a tuft of scales. 



Described from numerous bred specimens. The species has the general fticies of the European 

 Cryptoblabes bistriga, which is a larger insect. 



Larva. — Length 0.45 — 0..50 inch. General color olive, or pale green, or brown, with a broad dark 

 stripe along each side of back. Tapers slightly both ways, joints 4-12 inclusive, divided into 

 two transverse folds. Freckled with numerous pale specks and with piliferous spots, the specks 

 often taking the form of two pale broken lines along the upper edge of dark stripe. The piliferous 

 spots are jjale with a central black dot,, and are best seen in the dark specimens. On joints 4-12 

 inclusive they are placed 4 in a square on the middle of the back, and four more each side, the two 

 upper lateral ones being on the anterior fold, the stigmata appearing as minute rufous specks between 

 them. Both these spots are often double. The third lateral spot is on the posterior fold and the 

 fourth ;is Isubveutral and anterior. The hairs proceeding from these spots are long and setaceous. 

 Head horizontal, freckled, pale behind, tinged with gi-een in front and with a few long hairs. Joint 1 

 also freckled and with a large black piliferous tubercle with a pale basal annulation and in range with 

 middle of dark stripe. Joint 2 with similar black tubercles with a white centre and replacing the 

 uppermost lateral pale spot. There are but two of the small pale dorsal piliferous spots on this joint 

 (between the tubercles) as well as on joint 3. Beneath immaculate, except that the thoracic legs have 

 sometimes a few dusky dots. 



In the very dark specimens the head, cervical shield and anal plate remain pale. The cervical 

 shield is then well defined with four small piliferous specks at anterior edgae, and the large shiny 

 tubercle forms the extreme anterior angle. 



In many siiecimens the subdorsal dark stripe is obsolete or sub-obsolete, but even then the four 

 black tubercles on joints 1 and 2 characterize the larva sufficiently. 



Described from numerous specmiens. 



Pupa.— 0.24: inch long; rather stout and short, with two minute diverging spines and a few stiff 

 bristles at tip. 



THE GEEEN APPLE LEAF-TYER.— Torfrfj- Cinderella, N. Sp. 



[Fig. ■:■>.] 



(Lepidoptera Tortricida? .) 



In company with the foregoing Leaf Skel- 

 ctonizer may almost always be found two or 

 three different species of small green worms 

 which aid materially in withering and denud- 

 ing the leaves from young ajjj^le trees. These 

 worms bear so close a resemblance to each 

 other that it is almost impossible to character- 

 ize them. The species under considei-ation is 

 of a uniform yellowish-green color, with the 

 head and neck horny and a shade more tawny, 

 the head being marked with a crescent-shaped 



* Genera and families, so-called, are often instituted on such trivial and even variable characters 

 amsng the smaller moths, that the proper placing of a species becomes very ditlicult, and ofttimes 

 impossible. As Mr. Walsh informed me in 18G9, specimens of this moth were that year sent to the 

 English microlepidopterist, Mr. H. T. Stainton, who refei-red it to the genus Acrobasis (See Am. Ent. 

 I p. 32) . Upon carefully examining my own specimens, I found that the anteunal characters of the 

 cf placed it in the genus Pempelia rather than Acrobasis, and I at once suspected that the specimens 

 sent by Mr. Walsh to Mr. Stainton were all Q . Upon communicating with Mr. Stainton on the sub- 

 ject, and sending him the cf, my .suiipdsition was verified. But, after all, as the late Dr. Clemens 

 tritely remarked, our system of classification is yet "one of convenience and not of nature."
