surface near tip, 4 on the under surface near the side margin, 8 on 

 the upper surface near tip, 1 on under surface near tip and 2 on the

Recently Hatched Larva. — Length 2.2 mm. Width of head 0.15 

 mm. Uniformly white, tinged with yellow save legs, which are red- 

 dish and head which is uniformly black with mouth parts lighter. 

 Head bears several fine long hairs. Thoracic shield brown. Each 

 body segment bears eight fine hairs, four on dorsal surface and two 

 on either side, two of the dorsal hairs and four of the lateral forming 

 a transverse row. Hooks of prolegs elongate. Longitudinal lines 

 of developing larva absent. 



Full Grown Larva. — The following description is by Busck : " The 

 larva is rather large when full grown in proportion to the imago, 

 being 22-23 mm - ^ on S an d with greatest width 2.2 mm. It is cylin- 

 drical, only slightly tapering fore and back. Head rounded, shorter 

 than wide, black, with reddish brown vertex; width 1.3 mm. First 

 thoracic segment somewhat narrower than the following joint, red- 

 dish, thoracic shield black, width 1.6 mm.; length 0.7 mm.; straight 

 in front and nearly straight posteriorly. Second thoracic segment 

 dark reddish, with anterior part white above. Third thoracic seg- 

 ment and the rest of the body white; on the posterior half of this 

 joint begin six wavy, narrow interrupted longitudinal dark reddish 

 dorsal lines, which run through on all the rest of the segments. 

 These lines are darker in the young larvae, which otherwise are like 

 the full grown larvae. Tubercles shining deep black, bearing short 

 black hairs; they are arranged conspicuously on the white part be- 

 tween the dark lines. Ventral part of abdominal segments white. 

 Thoracic feet black; abdominal prolegs normal, white, with a com- 

 plete circlet of brownish hooks." 



Pupa. — Length 6-7 mm. Greatest width 2 mm. 



Adult. — Gelechia hibiscella. Busck's description is as follows: 

 "Antennae dark brown, not annulated, slightly serrate toward the 

 tip. Labial palpi with well-developed spreading brush, yellowish 

 white; second joint with a few black scales on the outside; terminal 

 joint with tip and one annulation near base black. 



" Face, head and thorax shining ocherous white ; shoulders pur- 

 plish black. Costal half of forewings dark brown, in some specimens 

 nearly black; dorsal half including apex light ocherous brown, in
