108 Dr. B. P. Uvarov’s Notes on the 
Choroedocus, one of them being identical with G. capensis 
Thunb. Thus, the number of species of Choroedocus known 
to date is four, three of them, being represented in the 
Museum collection. The genus is truly Oriental in its 
distribution, since Thunberg’s capensis, in spite of its 
name, has proved to be an Indian ‘insect.

I have established the identity of G. capensis Thunb., 
and H. insignis Walk., by comparison of Walker’s types 
with one of Stil’s specimens, which has been also com- 
pared by Prof. Y. Sjéstedt with Thunberg’s actual types. 
As one of Walker’s types is from India, and there is a 
series in the Museum collection from the island of Hainan, 
with one specimen from China, it is evident that the 
species is an. Oriental one. Stil’s specimen of the male 
is also from India. It is, therefore, very strange that 
Thunberg should have described the species as a South 
African one, ‘‘in campis Africae frequentissimus”’; the 
only explanation (suggested by Prof. Sjéstedt) is that 
Thunberg went to India after his stay in Cape Town, 
and the data on the specimens became mixed; the above- 
mentioned note of this author concerning the frequent 
occurrence of Gryllus capensis in Africa might be possibly 
referred to any species of Heteracris, the females of which 
somewhat resemble Choroedocus. 
This particular species is separable from the very closely 
related C. dlustris by more numerous and larger black 
spots on the elytra; the males also possess quite a good 
character in the shape of the subgenital plate which is
