V-shaped fine white line. Antennae three-jointed: first joint 

 very large, broadly conical; second thick oval, with a very long, 

 stout hair at outer side of tip ; the third minute. Ocelli five, 

 black, placed behind the antennae, in a curve opening down- 

 ward. 



Labrum broadly emarginate, with rounded lobes. Maxillae 

 and labium pale beneath, with dark sutures, strongly contrasting 

 with adjacent parts of head. Mala and palpi brown. Labial 

 palpi minute. Maxillary palpi three-jointed, large; first joint 

 nearly as thick as the palpiger, and about as broad as long; 

 second joint cylindrical, width two-thirds the length; third joint 

 tapering, about two-thirds as long as the second. 



Body with six conspicuous rows of long, pale hairs, longest on 

 the posterior segments, one hair of each row to each segment, 

 each borne on a minute black pilif erous tubercle scarcely as large 

 as the spiracle. One row above spiracles, another equally dis- 

 tant below, and two subdorsal rows. Other smaller hairs irreg- 

 ularly distributed. 



Cervical shield yellow, smooth, with a few scattered hairs and 

 two curved brown blotches, one on each side, separated by a 

 yellow median spot. Anal plate coriaceous, brown, heart-shaped, 

 with six long stout hairs at its posterior margin. Posterior seg- 

 ments without spines or tubercles at hinder margin, differing 

 here from the peach borer. Spiracles black, nearly circular, 

 anterior pair but little larger than the remaining eight, last pair 

 not exceeding the eighth in size. 



Thoracic legs pale reddish brown externally, paler within, 

 with dusky tips. Each proleg except the last pair with a com- 

 plete close circlet of large hooks, and several smaller ones be- 

 sides, and also a horny black central disk or tubercle within the 

 ring. Last pair with a single half circlet of very strong, close- 

 set hooks. 



Imago — Expanse 20 to 25 mm. Head and thorax dusky gray, 

 with bright bronze reflections. Abdomen similar, and also 

 brightly bronzed, but with edges of segments pale. Fore wings 

 light gray with brownish red and black markings. Posterior two- 

 thirds of basil field brownish red with scattered reddish scales 

 along the costa also, the reddish tint deepest along the middle of 

 the wing. Basal line near the middle of the wing, white, some- 

 times obsolete posteriorly, making, when complete, two external, 

 and three internal angles. Middle field black mixed with gray, 

 except at posterior margin, where it is largely suffused with red- 

 dish orown. White scales usually forming distinct discal spot, 

 in one case broadly ringed with black. Outer line variable, wnen 

 distinct with two internal and one external angles. Commonly 

 distinctly bordered with black within, and followed without by a 

 reddish shade (except near costa, where this merges in black) 

 which is broadly bordered by light gray. A marginal black line,
