NO. 1376. LEPIDOPTERA OF THE KOOTENAI DISTRICT— DYAR. 797 



Family NOCTUIDJ:. 



APATELA DACTYLINA Grote, var. HESPERIDA Smith. 



Eleven specimens, June 13, IG, 23, 25, 3(», July 2. Tiic specimens 

 are generally darker and more smoothly colored than eastern dactijlina^ 

 but Professor Smith's type of hesjxrUla is not so, and I scarcely see 

 wh}^ he should have separated it. Still, he.sjJerida is a good racial form, 

 representing dactylina in the northwest. The larva is essentially the 

 same, though the hairs are of a decidedly brighter brown, and are less 

 markedly keeled on the dorsal line. 



Egg. — Flat, circular, low domed; ribs about 80 at the margin, 

 smoothly waved, diminishing ])y alternation toward apex, which is 

 irregularly lumpy; no reticulations. Dark green, later with little red 

 dots, sparsely scattered. Diameter, 1.4 mm. ; height, 0.4 nun. Hatched 

 in eight days. 



Stage I. — Head bilobcd, cordate, w^hite, checkered with a more 

 sordid shade, ocelli and coarse setas black, jaws brown. Hairs single, 

 the dorsal ones black, long, the lateral ones white and shorter; no sub-

 ous; hair of joint 11 all pale; shields undifferentiated. 



Stage II. — Head bilobed, a little higher than wide, white with l)lack 

 marks; triangular mark in clypeus, median suture at apex, curved 

 band each side of clypeus and a mark on side; width, 0.8 mm. Body 

 normal with large round warts, Avhite, with white hairs, joints 5, 7, 

 and 12 dorsally with a small dusky patch and a few dark hairs. Hairs 

 soft, long and short mixed. 



Stage III. — Head sharply bilobed, with stiff white seta^ shining- 

 black, a dash from vertex of lobe, clypeus and epistoma white; width, 

 1 uun. Body uniform, warts round, projecting, all covered by tine 

 long flutl'y white hairs; a long dorsal black pencil on joints 5, 7, and 

 12; sides ])roadly powdered with ))lack, iiu-losing wart iii. Thoracic

 the ])road white dorsal space.

 shining black; Avidth, 1.8 nun. Body black, obscured by the dense 

 secondary hairs, warts ii and iii showing white. Dorsal hairs dense 

 in banded segmentary tuftings, ereamy brown; subdorsal and lateral 

 hair long, white, sparse, showing the black ground; erect black pen- 

 cils on joints 5, 7, and 12. Feet ])lack, except the claspers of the 

 abdominal ones. 



StageV. Head shining black; width, 3 nmi. Body black, the warts 

 obscured, except sul)ventrally by l)road l)ands of dens(\ s(>condary
