EEPORT UPON COTTON INSECTS. 



nous and quite numerous at and near the lateral edge ; antennae short, 2-jointed, 1st 

 joint yery short and thick, the 2d scarcely one-half the diameter of the 1st, slightly 

 conical and rounded at tip ; the 1st thoracic segment bears 6 quite long, pointed 

 tubercles, arranged in a curve around its lateral and front margin ; the stigmata are 

 upon short processes, and, are placed close together near the middle of the segment ; 

 all other segments, except the two last, have on each side one quite long, slender 

 tubercle, somewhat posterior to the middle, and, in a transverse row dorsally, 4 short, 

 fleshy, conical tubercles and a somewhat longer one ventrally near the lateral edge, 



a little in front of the lateral 

 one ; the 12th segment has its 

 spiracles, which are situated 

 near its center, prolonged into 

 rather long, fleshy tubercles; 

 this segment bears on each side 

 two tubercles, one at the ante- 

 rior and the other at the pos- 

 terior angle ; the last segment 

 is furnished with 4 tubercles, 

 one on each of the posterior 

 angles and two near the center 

 of its posterior margin, the two 

 lateral ones longest. 



PUPA. Length 2.8 mm ; color 

 light brown ; the whole surface 

 FIG. 49. Phora aletiae. is covered with small roundish 



granules, which are the remnants of the tooth-like processes which were noticed 

 on the larva ; from the 1st abdominal segment the body tapers rapidly to the head ; 

 the 1st abdominal segment bears dorsally, near its front margin, two very conspicuous 

 black horns, slightly directed backward ; the lower two-thirds of each horn is 

 nearly straight, and the last third is curved gently outward; it is thickest at its 

 base, and becomes slightly thinner towards its apex; all the lateral tubercles and the 

 last pair of spiracles are very much reduced in size in comparison with the correspond- 

 ing ones in the larva, the tubercles of the last segment, however, remaining of nearly 

 the same size; the dorsal portion, between the horns and the last pair of spiracles, is 

 greatly convex, the lateral margin being flattened; it is traversed in nearly equal dis- 

 tances by 4 prominent, rounded, double ridges : each of the 2 posterior ridges, which 

 are somewhat broader and higher than the front ones, bear 4 round warts, which are 

 the remnants of the dorsal tubercles of the larva, and the last pair of spiracles is situ- 

 ated on a rounded elevation; the ventral portion is slightly rounded and without any 

 particular markings. 



IMAGO. Female: Length of body, 2.3 mro ; front of head dark yellow, beset with 

 16 stiff, black, spine-like hairs; eyes black, coarsely faceted, covered with minute 

 black hairs, and edged posteriorly with some longer spines; antennae 5-jointed; 1st 

 joint very much swollen, almost globular, and very hairy; the next 3 joints are very 

 small, all three together not longer than the 1st, having only about one-fifteenth of the 

 diameter of the 1st ; the 2d and 3d are about equal in length ; the 4th is a little shorter ; 

 all; are slightly thinner towards the base, beset with fine hair; the 2d joint is inserted 

 on the upper side at about the middle of the outer margin of the 1st segment; the 5th 

 joint, or bristle, is very long and delicate, and is closely beset with short, spine-like- 

 hairs; the labium, when extended, is quite long and fleshy, and seems to be composed 

 of 4 pieces or iobes ; the basal piece is somewhat narrower than the 2d, which broadens 

 at its middle ; the 3d piece is somewhat smaller than the 2d, straight posteriorly and 

 gently rounding towards the apex ; the last piece is very minute and knob-like ; the 

 labium is sparsely beset with quite long hairs ; the maxillary palpi are 2-jointed, the 1st 

 very short, scarcely noticeable, the 2d very long, petiolated, with its apical half broadened
