dirty brown colour; some species of the same family make white 

 shells, and the shell fabricated b}' one species resembles that of a

One of the figures in Dr. Dobsons paper, previously noted, 

 appears to represent the lerp of this Psyllid.

COMETOPSYLLA KUFA, ll.sp. 



(Plates xii., tigs. 6 and 21; xiv., fig. 18). 



Lerp crystalline white; 1J lines in diameter, clustering together 

 in such numbers as to completely encrust and quite whiten the 

 smaller branches of E. melliodora. Circular, convex, closely 

 attached to the bark, and fitting close to the imprisoned larva; 

 when freshly formed showing a transverse ribbed structure, but 

 as they are enlarged becoming irregularly rounded brittle 

 crystalline lumps that break very easily. 



Larva dark brownish-yellow; antennae, legs, blotches on head, 

 marks and spots on thorax, the interrupted bars on upper surface, 

 and the whole of apical portion of abdomen black. Slightly 

 hirsute on front of head; apex of abdomen thickly fringed with
