Conchaspincs. 2 1 



merely by a thin whitish fihri adhering to the plant {fig. 9). 

 Diameter of mature scale about 5 mm. 



Male puparium {fig. 7, a) white, oblong, flattened, closely 

 felted, completely enveloping the pupa. The hinder extremity 

 has a valvular opening. Length 1*50 mm. Breadth, at widest 

 part, about 075 mm. The male puparia do not occur separately, 

 but are always collected together, in groups of ten or more, 

 beneath the parent scale {fig. 7) which they completely fill. 



Adult female reddish brown {fig. 9). Surface chitinous and 

 shining, minutely rugose with lines of irregular raised spots. 

 Form oblong {figs. 11, 12), rounded in front, abruptly narrowed 

 behind the thorax: segments well defined. Eyes {fig. 13) large, 

 situated dorsally each in a conspicuous circumscribed oval space 

 of a paler and clearer colour than the surrounding area. Body 

 terminating in a blunt point ; the extremity fringed dorsally with 

 eight short pointed processes {fig. 18), the margin thickened and 

 strongly chitinised {fig. 19). On the lateral margins of each of 

 the three last segments is a small broadly rounded chitinous 

 transparent lobe {fig. 19). Each segment of the body bears a 

 lateral tuft or group of three or four stout hairs, those on the 

 anterior parts longest, the others diminishing as they approach 

 the extremity. The abdominal segments are strengthened by 

 broad bands of firmer texture, especially towards the extremity, 

 where they are interrupted in the centre, and take the form of 

 distinct circumscribed plates. The last dorsal pair of these 

 plates simulate the anal lobes of the Lecaniinae, but they are 

 continuous with the general surface of the tegument, and have 

 no free extremity. Antennae situated within the margin on the 

 ventral surface {fig. 12), consisting of three distinct joints only 

 {fig. 20), though there are sometimes traces of an indistinct sub- 

 division of either the terminal or second joint : first joint short, 

 constricted at the base ; second joint longest ; extremity of third 

 joint truncate, bearing a crown of short stout hairs, of which one 

 is considerably thicker than the others ; the first and second joints 

 have each a single longish stout hair on the side. Rostrum large 

 and conspicuous ; mentum biarticulate.* Legs stout and well 

 developed {fig. 14), extending considerably beyond the margin 



* By a slight error of the lithographic artist the mentum [171 fig. 12, pi. IIIa) 

 is made to appear triarticulate. An extra joint has also been added to the 

 antennjE in the same figure, making them 4- instead of 3-jointed.
