markings of the elytra buffish ochraceons ; the pubescence between these markings 

 is duller green than in the pi-incijjfilU pn'ncij/al/n. This Angola form may 

 be called

A very distinct species, easily recognised by the jiattcrn of the elytra.

Drury's St. mirabilis is dichromatic, nymotypical mirabilis being the green 

 form and amabilis the tawny one. 



The base of the jjronotnm in nmubiiis is green, as iu S. iiD/n'rialis V. ; 

 the elytra bear a green sutnral spot as in .S'. rknjsopras, but the sntare is more 

 or less extended green also in front of and behind this spot ; sometimes the 

 ochraceons markings are separated by more or less green interspaces. The 

 structure by which the species can be most easily recognised is the basal tooth 

 of the mandible of the male. This tooth, as Kolbe has already explained of 

 submaculata, is curved inward, the tips of the two teeth pointing towards each 

 other. 



There appear to be several other species which have a tawny and a green 

 form. 



I add a note on another species of Sfrrnotomis, described by AVestwood : 



Sternotomis virescens.

The markings of worn specimens are much smaller and greener than those of 

 fresh ones, which are chalky white or but slightly greenish. In the examples 

 from Uganda the markings have sometimes an ochraceous tint. 



Sternotomis gama Coquerel, l.c. no. 4. t. 5. fig. 4 (1861) (Angola) is based on a 

 buffish individual of rircicens, and St. bohndorf Waterhouse, Ann. Mag. N. H. 

 (5) xvii. p. oOl (1886) (Niam-Niam), also does not seem to be specifically different 

 from rirescens.
