The Yapi specimen does not quite agree with these in that 

 it has the first transverse yellow band only very narrowly 

 interrupted before the lateral margin. 



Mylabris hermannioides, sp. nov. (see Plate B, fig. 9 and 

 the left-hand specimens of figs. 10, 11). Of the size and 

 facies of Coryna hermanniae, F., from which it may readily 

 be separated by its black antennae; these are rather indis- 

 tinctly 11-jointed, the last two joints fitting closely together, 

 but not so completely fused as in the subgenus Decapotoma. 



The intrahumeral basal patch is more elongate than in 

 hermanniae, extending well beyond halfway to the first trans- 

 verse band ; both these bands are broader towards the suture, 

 though almost or quite interrupted at the suture itself, and 

 both are again almost interrupted near the margin by a 

 process from the black area behind them. 



From small specimens of Decapotoma ajffinis, Oliv., it may 

 be distinguished by the intrahumeral patches being sub- 

 parallel, not becoming wider behind and not tending to come 

 together on the suture ; in affinis they are subtriangular, some- 

 what oblique and tending to coalesce on the suture. In the 

 latter species too the transverse bands are broader and of 

 roughly even width throughout. 



Var. lambomi, nov., is a striking variety (see Plate B, 

 figs. 12-15, and the right-hand specimens of figs. 10, 11) 

 analogous to D. affinis, var. caltemauti, with which it was at 

 first confused. The black has disappeared from the anterior 

 half of the elytra except for a small humeral patch and a 

 long narrow wedge running back along the suture almost as 

 far as the post-median black band. The apical half of the 

 elytra remains unaltered. It may be distinguished from var. 

 caltemauti by its yellower, less tawny colour, its less silky 

 pubescence, and by the shape of the scutellar black area. 

 In caltemauti this forms almost an equilateral triangle, with 

 sometimes an extremely narrow prolongation along the 

 suture. The variety would seem considerably to outnumber 

 the typical form, 40 specimens in all having been received 

 against only 5 of hermannioides, but of these 21 were sent in 

 the two previous years by Mr. Lamborn as a distinct species. 

 The hermannioides form has doubtless been largely over-
