NOTES ON COCCID-INFESTING OHALCIDOIDEA — II. 



245 



toruli, and ventro-laterally nearly to the genae, the entire surface is much raised- 

 reticulate, the walls of the cells appreciably thickened, producing the effect described 

 in the colour notes. The pattern is fine, especially where the eyes approach one 

 another most nearly ; each little cell has, under a high power, an appreciable depth, 

 yet the surface cannot correctly be described as pitted or punctured. Where the 

 pattern is thus greatly raised there are no bristles, except for the usual row (minute) 

 on the orbits ; between the toruli and on the clypeus there are in all about 30 minute 

 bristles, 2 (1 : 1) longer, near the clyi)eal edge above, and 4 (?) from below ; there are 

 a few bristles on the genae, and upwards towards the occiput, on which the pattern 

 is long drawn out, but little raised.

 (b) C. cyanonotus, sp. n., $. 



Month-parts : mandibles (5 : 3) (fig. 6 b) elongate, with practically only 2 teeth, 

 the upper pair fused, with a single broad lobe ; trophi with a coarse raised pattern 

 on the stipes and mentum, which bears two central bristles ; maxillary palpus, 

 15 : 10 : 15 : 27 ; the fourth joint being relatively longer than in the next species 

 and a little narrower (3 : 1). 



Antennae (fig. 5 a) : length, -8 mm. Scape (19 : 10) enormously dilated, with 

 coarse reticulation ; bare on the outer aspect ; many regularly but rather sparsely 

 set bristles on the inside ; the last row standing somewhat above the ventral edge. 

 The scape is shorter (10 : 11) and a little broader than the club, and just equal to the 

 funicle. Pedicel (5 : 3) about one-third of the scape in length ; longer than any of 

 the funicular joints, which are all transverse. In the funicle, joints 1-4 are wider 

 ventraUy than dorsally, in the fifth the sides are about equal, and in the sLxth the 

 dorsal edge is longer, thus giving the antenna its characteristic medianly decurved 

 appearance. The bristles in the funicle are rather long ; joints 5 and 6 bear four 

 sensoria each ; the club is nearly twice (12 : 7) as broad as the sixth funicular, which 

 is twice as broad as the first, and bears a large ventral sense-organ and 10, 10, 7-8 

 sensoria.
