clearly, such as I notice in the British Central African specimens ; 
the thorax also shows two median parallel pale lines and two 
lateral ones on the posterior half of the mesonotum, and I 
noticed in this specimen three very distinct lines of dark bristles, 
the lateral ones ending in a clump of bristles at the scutellum. 
This I take to be only a local variety, var. a, Mombasaensis 
(Fig. 165). 
It is a very annoying species. Two 5’ s sent by Mr. Marshall 
from Mashonaland were at first taken to be a distinct species, 
but as there are no structural differences, I include them here as 
varieties of C. maculicrura. The two spots on the first abdominal 
segment are deep black only, there being no creamy scales, and

they present rather a dusky brown appearance, and seem more 
stoutly built, and the white basal lateral patches are very 
distinct. They are also somewhat smaller in size, but the 
venation, the spotted legs, the apical banding and spotting of 
the abdomen and the scale structure, agree so closely with the 
type that they cannot be separated even as a distinct variety. 
Dr. Bancroft has sent me a series from Queensland, which 
exactly agree with the types from Africa. 
A specimen received from Freetown, Sierra Leone, presents 
a marked difference in regard to the abdominal ornamentation, 
and I have therefore separated it from C. maculicrura as another 
variety. 
Yar. b, Sierraleonis. 
Thorax dark brown, with two parallel pale lines running 
from the front to the scutellum and a pale line on each side 
from the middle to the scutellum, with scattered pale scales 
laterally; very much like var. A, Mombasaensis.
