Ovisac loDg, narrow, composed of the ordinary close white cottony 

 material. Long 5-7 mm., wide 2 mm. 



Larva normal, with 3rd joint of antenna longest; anal emavgina- 

 tion wide. 



All the females seen were located hehind the whorls of flowers of the 

 food-plant; none were found in exposed situations; in order to see 

 them it was necessary to remove the flowers, etc., from the stem, but 

 on doing this the sacs were much broken, and it was difficult to obtain 

 perfect examples.

$ Adult immediately prior to gestation (fig. 2, a. & h.), elongate ovate, 

 nnrrowed behind from the thoracic segment ; beneath olivaceous, above 

 paler, with the black viscera, etc., showing through the dermis ; there are 

 two very long white filaments at the anal extremity, but marginal 

 plates are entirely wanting; radiating from all parts of the body above 

 are numerous very long, delicate, waxy filaments; these latter in the 

 more advanced stage, and when egg-laying has taken place, become very 

 dense, and matted below, completely covering the insect; projecting 

 from the thick matted mass, are very numerous, and exceedingly long, 

 delicate filaments, varying in length from 5 to 10 mm. ; these superfici- 

 ally have much the appearance of sponge spicules, as many are perfectly 

 straight and cross each other in all directions; all the specimens received 

 were aggregated together in masses completely covering the under sides 

 of the leaves (fig. 2c.), Antenna (fig. Id.) of 8 joints, of wliich 3 and 

 8 are equal and longest, 2 shorter, 4 to 7 shortest and equal : all with 

 fine hairs. Legs long, hairy ; hairs at apex longest; tarsi a little less 

 than one-third the length of the tibise ; the latter with a short spine at 

 apex ; digitules of tarsi slender, those of the claw stouter and much 

 dilated at extremity (fig. le.). Rostrum biarticulate with many long 

 hairs ; unexpanded filaments about three times the length of the 

 rostrum, not quite reaching the insertion of the intermediate legs. 

 Anal ring with 6 short hairs, intervening spaces with clear circular 

 spaces, or slightly raised discs. Anal lobes normal, each with a very 

 long hair, and two or three strong spines. Dermis : ventral surface 

 between antennse in front with numerous long hairs and clear circular 

 spaces, or spinneretts, surrounded with from 3 to 5 hairs, tliese occur
