faintl3' produced but not distinctly tuberculate; these are also furnished with one or two rather long 

 hairs. Tip of genital armature wideh' rounded and faintly emarginate ; base scarcely wider than the apex, 

 sides parallel. Wings faintly infuscated. Antennae brownish-black and furnished with very long hairs; 

 apical Segments wanting. 



Length frotn point of head to tip of the closed wings 2,50 mm. 



The anal tubercles of the male, in life, would no doubt be furnished, each with a single long 

 filamentous appendage, but these had entirely disappeared in the alcohol. I assume that there would be 

 three pairs of these filaments present, in life : one long median pair and two short lateral ones. 



These insects (the females; give off a pale dull orange stain in alcohol; which permanently stained 

 the white paper labels a dull pale red. It is very rarely that coccids produce such an effect in alcohol and 

 may, therefore, be taken as a ver}- marked character. 



In form and colour the female looks like a ver}- small form of Monophlebus sjöstedii Newst. 

 M. africanus differs in being much smaller, has a much shorter terminal segment to the antenna, and has simple 

 tarsal spines. The male may also be distinguished by its pale infuscated wings; a character which is 

 apparently unusual in the males of this genus.

Lophococcus mirabilis var. tricornis n. var. (Newstead). 



Female, adult Dark castaneous, in alcohol; extemal surface faintly polished. Form roughly 

 hemispherical with three enormous hom-like projections on the dorsum, arranged transversely in the form 

 of a trident; the middle one, the longest, measures 7 mm from base to tip and is equal to the width of the 

 body at the margin ; lateral homs 3,5 mm long, project considerably beyond the sides of the body ; all the 

 homs are rather flat at the base but have rounded ends; margin strongl}- and irregularly crenulated the 

 prominences being bluntly spinöse; posterior margin deeply emarginate. Ventral orifice covered with a 

 secretionary Aap. Derm of venter densely clothed with strong, narrow, lanceolate spines in the mid 

 region between and surrounding the legs ; beyond this the spines are few in number and smaller. Spinnerets 

 at the margin of the large ventral orifice packed closely together; these present a large quatrefoil pore. 

 Antennae of 10 segments, the last in length equal to the three preceding ones; all the segments with 

 fine hairs. Legs well developed and stout, resembling those of other Monophlebids. Length at base 

 7 mm; width 7,50; height from base to tip of middle spine (longest axis) 10 mm; expanse of lateral 

 spines 11 mm. 



I am under the impression that this insect will prove, eventually, to be quite distinct from Cockerell's 

 L. mirabilis-), as the difference in the externa! form is very marked indeed, mirabiiis having but one "stout 

 erect spine about 3 mm. long, like a spike on a military helmet" (Cockerell 1. c). It is true that an 

 additional pair of spines are also present, but the author says that one of these does not amount "to more 

 than a nodule'', whereas in the var. tricornis the lateral spikes or homs are nearly as long as the central 

 one. Otherwise the two insects agree.
