The eighteen examples obtained by Mr. Betton show the usual 

 uniformity of pattern characteristic of the Northern species of this 

 group, and are all readily separable from the Southern, East- 

 Central, and Western species, which Mr. Marshall proposed to 

 unite under one name : only one example of the yellow female (to 

 which I gave the name of T. abyssinicus) was obtained ; indeed 

 yellow females of the T. eris group seem to be rare.

The wet form of the male and the yellow form of the female of 

 this species are new to the Museum series. Most of the specimens 

 are of wet or intermediate types, but one female combines a 

 wet-season upper surface with an extreme dry form of under 

 surface.
