OBSERVATIONS ON SCALE-INSECTS (COCCIDAE) — IV. 15 



Propupa. Turned to dull crimson in cold KOH. Very robust. Frons with one 

 pair of bristles. Genital sheath short, obtuse. Abdominal segments with a few 

 stiff hairs. Length, 0*8 mm. 



S. Nigeria : Agege, on pigeon-pea stems, 1914 (Dr. W. A. Lamborn). 



Male (imperfect). Head slightly longer than broad ; ventral surface (fig. 9, b) 

 with two divergent narrow sclerites, and four pairs of bristles, which are separated 

 by a median longitudinal suture, the distal pair on the frontal margin. One pair 

 of ocelli near the apex formed by the sclerites. Thoracic apodeme normal. Legs 

 long, sparsely clothed with bristles ; claws rather strongly falcate ; lower digitules 

 with slightly longer knobs than those of the tarsi. Abdomen very elongate ; the 

 segments with submedian and lateral bristles, the terminal segment with a pair of 

 very long marginal bristles. Genital armature (fig. 9, a) with three pairs of long 

 bristles ; stylus in two parts, with the tip of one bluntly rounded, the other truncate. 

 Length, 1*3 nun. 



Larva. Marginal spines (fig. 9, c) of two forms ; minute club shaped ones, alter- 

 nating with immensely long, stout, curved and barbed ones. 



Uganda : Kampala, on Markhamia platycalyx, 2.ix.l5 (C. C. Gowdey). 



Asterolecanium spectabile sp. nov. 



Femah puparium. Lanceolate and convex dorso-ventrally ; margins broadly 

 flattened, with slight constrictions opposite the stigmata ; slightly narrowed and 

 produced posteriorly. Surface strongly punctate ; a definite narrow median suture 

 extending nearly the whole length of the puparium, the suture faintly interrupted 

 at legular intervals along the abdominal region, suggesting segmentation. Colour 

 brilliant orange-crimson, with black suffused markings anteriorly, the latter due to 

 the under-lying shrivelled body of the female ; the narrowed posterior end opaque, 

 glassy and colourless ; the cephalic margin narrowly orange- crimson. Fringe com- 

 posed of closely adjacent, straight, glossy filaments of a pinkish colour ; in very 

 young individuals this lies flat upon the surface of the leaf, but as the ventral portion 

 of the test gets more and more convex (exteriorly), the fringe drops and becomes 

 vertical ; as a rule, it is either entirely wanting or can be traced only in isolated and 

 abraded patches. Length, 1*3-2 mm. 



Female, adult. Form somewhat doubtful, but clearly very elongate and probably 

 filling the test at gestation. Rostrum approximately central. Paired or 8-shaped 

 pores disposed in a single row, not extending to the posterior extremity or the extreme 

 cephalic margin. A short series of small circular glands on the ventra margin 

 opposite the thoracic stigmata only. Tubular glands geniculated, with the proximal 

 end attenuated ; these are distributed over the whole of the dorsal area ; their 

 length equal to the greatest diameter of the rudimentary antennae, approximately. 

 Abdominal extremity with two minute setiferous lobes ; setae short and with their 

 tips broken away in all the preparations (eleven). Anal ring hairless, its diameter 

 not much greater than the basal attachments of the setae of the lobes. Genital 

 orifice relatively very large, transverse, and placed well away from the anal orifice. 

 Rudimentary antennae with three to four extremely minute spines.
