THE STATE ENTOMOLOGIST. 145 



This after-comer is of a yellowish or grayish-white color, often with dark 

 marks on the back, a light brown head, and a horny piece of the same 

 color on the first and last joints, and small hair-emitting dusky points over 

 the body (see Fig. 66, c, d, e). It is, withal, easily distinguished fi-om the 

 weevil larva by its full complement of six true and ten false legs. It 

 changes to the chrysalis within its borrowed domicile, and the chrysalis 

 gives forth the moth by first pushing partly through the silken door. 



The moth (Fig. 66,/, ?) is ash-gray in color, and characterized chiefly 

 by two distinct spots near the middle of the front wings and a transverse 

 pale stripe, well relieved behind, across their basal third. The male ditfers 

 from the female by the basal joint of his attenn® being much flattened and 

 articulating with the stalk by means of a nodule (Fig. 66, g). The moths 

 issue all along from the end of April till September. They vav}- 

 much in size and conspicuity of design. The following description of the 

 species was first published in the Canadian Entomologist (Yol. IV, pp. 18 — 19). 



HoLCOCERA GLANDULELLA, Riley, (Fig. 66,/, 5) — Imago. — Ahir expanse O-oO — ().80iuch. Front 

 wings silvery-gray, more or less distinctly suffused :ind marked with fuscous: two distinct dark discal 

 spots ; a pale transverse stripe across the basal third of wing, slightly elbowed outwardly at its middle; 

 this stripe is well relieved behindby a dark shade, and this shade generally extends from the elbow to 

 the costa above discal spots, forming a more or less distinct triangular shade in the anterior middle 

 portion of wing: three tolerably distinct dusky spots surround the discal dots on the outside; and a 

 series of minute vein-specks mark the posterior margin; fringes conoolorou^. Hind wings of a more 

 glossy, warmer, brownish-gi-ay, the reflection inclining to golden in certain.lights ; fringes con col - 

 oi-ous but not glossy. Under surface uniformly of same tint as hind wings. Head, thorax and legs 

 concolorous with front wings; abdomen with hind wings, the joints often ringed with a paler shade; 

 Apical joint tipped with yellowish or pale pnlvous hairs, the ovipositor of Q , which may be exserted 

 one-half the length of abdomen, of same color. The basal antennal joint of $ , the nodule on d" 

 attennffi, base of palpi, and sometimes tarsi, also tinged with fulvous. 



Described from 8 Qs, 20 c?s, all bred from acorns. The intensity of the dark shadings is quite 

 variable, and in some specimens the basal space shows decidedly paler than the rest of wing. 



Larva — Length 0.35 — 0.. 30 inch. Largest in middle of body. Translucent grayish-white, or yel- 

 lowish, with blue-black vesicular dorsal marks. A conspicuous light browai head and cervical 

 shield, and dusky anal plate. Head with the mouth parts darker, and the sutures and margins like- 

 wise darker and well defined. Piliferous spots small but quite noticeable from being brown, the 

 bail's springing from them pale and soft. The dorsal ones on ioints 2 and 3 are geminate and in a 

 transverse row (?". e. there are 4 pair. Fig. 66, c) ', while at the sides of these joints there are three tri- 

 angularly arranged, the front one sometimes double. Joints 4 — 12 with four, wliich are dorsal, nearly 

 in a square, the hind pair farthest apart (Fig. 66, e), two which are lateral in a transverse line with 

 stigmata (Fig. 66, d) , the lower sometimes double, and one which is subventral in middle of 

 joint, stigmata small and bright rufous. Legs same color as body, the thoracic tipped with brown, 

 the prolegs with a ring of minute brown hooks. 



Described from numerous specimens . 



Pupa — ^Light brown, smooth, with no characteristic marks.
