short bristle, and near their basal margin have a transverse narrow 

 ridge ; each of the segments from 1 to 7 has a small tubercle at about 

 the basal third of the lateral margin on which is located an ab- 

 dominal spiracle (fig. ee) ; these spiracles are very similar to the 

 thoracic (fig. dd) but smaller; last segment about half as long as 

 broad: on the dorsum on each side of the longitudinal middle line 

 are three spines close together, the middle one much the longer; 

 and exterior to these is one large spine with a small one at its base; 

 viewed from behind, in the middle of the segment, is a depression 

 with two rounded tubercles on the upper edge, and on the ventral 

 part of the segment are two conical projections terminating in a 

 sharp point; on the ventral side of the segments from 1 to 7 are 

 rows of spines like those on the dorsum. 



Length, 7 mm. ; diameter of thorax, 1.85 mm. ; diameter of ab- 

 domen, 1.25 mm.

Plate 3 



Pupa {fg. 16). — Fairly large, brick red; thorax shining, slightly 

 wider than the abdomen; abdomen cylindrical. Head rounded, 

 slightly depressed in front; antennal capsules small; tapering to a 

 point, closel}^ attached to the head below ; on dorsum of head, widely 

 separated, are two small tubercles, each with a bristle on top at the 

 apex. Thorax about as wide as long; along the medianly dorso- 

 anterior suture are two pyriform raised surfaces, each with a small 

 bristle-bearing tubercle; near the anterior angle is a large rugose 

 tubercle, upon which is located the thoracic spiracle (fig. -ff) ; the 

 large sinuous entrance place contains a series of small, mostly par- 

 allel yellowish slits ; in the middle of the dorsum is a pair of short 

 yellow bristles; the small plate at the dorso-basal part of the thorax 

 has a bristle at each anterior angle. Abdomen has eight faintly 

 rugose segments of nearly equal size ; first segment, on the posterior 

 half of the dorsum, has six bristles in a transverse row; segments 

 from 2 to 7 have a transverse posterior row of short, closely set 

 spines; segments from 1 to 7 have a tubercle on the sides at about 

 the anterior third and upon the tubercle is located a spiracle (fig. 

 gg) ; these spiracles are like figure ^^ but smaller and not quite so 

 rugose; last segment has a median transverse row of large, pointed, 

 spine-like projections on each side; from the middle outward they 

 are arranged as 3, 1, and 1; viewed from the rear the posterior end 

 of the caudal segment is concave medianly with four rounded
