Apical black area enclosing 

 yellow patch. 

 Black areas fail to reach mar- 

 gin, which remains yellow 



throughout holosericea, Klug. 



At least the two post-median 

 black areas reach the 

 margin farquharsoni, nov. 



.1/. (Goryna) hermarmiae, F., a series of 72 specimens sent 

 by Mr. Farquharson and Mr. Lamborn, shows some variation 

 in size, but is remarkably constant in markings (see Plate B, 

 figs. 7, 8). One specimen from Northern Nigeria in the 

 British Museum Collection has both the transverse yellow 

 bands broadly interrupted towards the margin. 



M. (Decapotoma) affinis, Oliv. The series of 59 specimens 

 represents the largest of the species from Ibadan, ranging 

 from 12 mm. to 20 mm. with the head extended. It, again, 

 is very constant in colouring, the yellow markings varying 

 but little in size (see Plate B, figs. 1-6). The var. caller nauti, 

 Mars., in which the yellow colour occupies the whole of the 

 anterior half of the elytra to the exclusion of the sub-basal 

 black area, is not represented in Mr. Farquharson's species, 

 though the British Museum possesses specimens from Sierra 

 Leone received together with the typical form. 



Mylabris temporalis, Wellm., described from Angola, is not 

 represented among the Ibadan series, but it is to this species 

 that I refer a single specimen in the British Museum collec- 

 tion from Yapi, Gold Coast. Though described by Dr. 

 Wellman as a Decapotoma, two co-types in the British Museum 

 received from the author have distinctly 11-jointed antennae.
