of any representative of the Diaspinae, which is all the more remarkable seeing that 

 the members of this sub-family are well represented in other parts of the continent. 

 That this group of coccids should be entirely absent from this region is, however, 

 highly improbable, all the more so seeing that such a universally distributed species 

 as Saissetia (Lecanium) oleae was found there. 



The African representatives of the genus MonopJileb-us in addition to the species 

 recorded in this work are M. fortis CKLL. and M. fuUeri CKLL., both from Natal; of 

 the former a single female was found under bark of Eucalyptus, and the latter, of 

 which females only were obtained, is said to be uncommon on grass heads. M. raddotti 

 WEST, (cf only) was discovered on the Gold Coast, in Western Africa. 



The remarkable and somewhat variable genus Walkeriana has hitherto been 

 represented in Africa by W. andreae GREEN, from the Congo; and W. pertinax NEWST., 

 from Central Africa. 



It is important to note that the hitherto monotypic genus Stictococcus was 

 founded by COCKERELL, in 1903, from material discovered by Dr. SJOSTEDT in Western 

 Afrika. That the same authority should have also discovered the second known 

 species of this genus, on the eastern side of the great continent, is of much interest. 



Saissetia oleae is not only a very widely distributed insect throughout the world, 

 but it is also practically omniverous, and has proved a great pest to the orange and 

 coffee and various other cultivated fruits and plants. 



A catalogue together with the descriptions of the new coccidae is herewith 

 appended.

Fig. A, 1 4. Female adult. (Fig. 1.) Slightly farinaceous: scantily pubescent 

 on the dorsum, but more so on the venter. Colour pale terra-cotta with a dull 

 orange tinge, when dry; when placed in alcohol dull red with a dull orange tinge. 

 Antennae and legs dark piceous, hairs greyish yellow. Form very elongate, highly 

 convex dorsally so much so as to appear almost cylindrical; segments strongly 

 defined ; margin forming a distinct keel or ridge. Antennae (Fig. 2) of eight seg- 

 ments, the first four shortest and in length about equal; fifth, sixth and seventh 

 much longer, equal in length; eighth very long, nearly as long as the three preceding 

 ones; all the segments with many fine hairs. Legs not reaching nearly to the margin ; 

 tibia (anterior) with numerous stout spines at the apex beneath; anterior tarsi 1 (Fig. 3) 

 furnished beneath with a double series of spines some of which are dilated apically 

 and suddenly truncate (Fig. 3c), this character being strongly pronounced in the apical 

 spine; claw (Fig. 3) with the tip bidentate, the larger upper tooth being paler than 

 the remaining portion of the claw; digitules (Fig. 3b) unequal, the shortest with a
