their ends at the same level. Lobes ordinary, well apart, 

 median ones small, with nearly the outline of a half-circle ; 

 second twice as broad as first ; third fully three times as 

 broad as first, with the edge minutely serrulate ; beyond the 

 third lobe the margin is very minutely serrulate, and there 

 are three distinct notches marking the limits of four broad 

 rudimentary lobes. Anal orifice a long distance from hind 

 end. Mouth-parts very large. 



The specimens are infested by a fungus.

Ceroplastes minutus^ sp. n. 



?. — Scale ^\ millim. long, broad-oval, convex, pale 

 yellowish, the dorsum thickly covered with bright lemon- 

 yellow wax, forming a large protuberance; plates not defined. 

 Scales solitary on the twigs. 



? . — When denuded of wax yellowish brown, depressed, 

 with a dorsal protuberance, and a large and thick but short 

 terminal horn. Antennae very pale, segments obscure, but

 almost touching them ; mouth-parts large, brown, rostral 

 loop reaching to anal ring ; legs very pale, ordinary ; tibia 

 little longer than tarsus, claw long, digitules rather stout. 

 Dermis after boiling transparent, non-chitinous, with many

Very distinct by its small size and other characters. 



Ceroplastes angulataSj sp. u. 



$ .—Scale 5 millim. long, 4^ broad, 4 high; very convex, 

 wax snow-white, shining, not divided into plates ; dorsal 

 nucleus dark, more or less covered by secretion ; no lateral 

 nuclei visible, but anal plates exposed ; on each side the 

 margin is produced into two prominent angles, to the tips of 

 which, beneath, run lines of chalky secretion ; these angles 

 represent the rays of Vtnsoma, to which the species makes an 

 approach. 



A very young individual is elongate-oval, bright yellow, 

 covered with transparent wax ; dorsal knob of wax trans- 

 versely grooved-striate.
