Report on a Collection of African Locustidas. 113 



indistinct transverse subliyaline markings ; costal and apical third 

 hyaline ; anal area probably green in life. Wings hyaline. Hind 

 femora glaucous on the outer side, the carin;© and transverse curves 

 rufous ; upper carinae serrated. Inner surface black, with a yellow- 

 ish space before and around the deep black crescent on the terminal 

 lobe ; a black line extends from it for a short distance on the outer 

 side below the lower median carina. Tibise and tarsi yellowish (red- 

 dish during life ?) with black-tipped spines, six or seven on the outer, 

 and seven on the inner carina. Prosternal tubercle transverse, not 

 narrowed at the extremity. Terminal spines on the inside of the 

 hind tibioe long, hairy, the second considerably longer than the first. 



Hcdi. Transvaal : Pretoria {Distant). 



Described from three males and one female. 



Closely allied to C.fratcrcula, but apparently distinct.

Genus Heteracris. 



Heicracris, Walker, Cat. Derm. Salt., iv, p. 655 (1870), 

 II Democlocus, Stal {nee Gu(^rin, 1842), Bihang Vet. Akad. 

 Handl., V (4), p. 75 (1878). 

 Walker's genus Heteracris is very heterogeneous; but as 

 Stal's name Democlocus is preoccupied, it will be convenient 

 to retain Walker's name in this restricted sense, rather than 

 to impose a new one, as twelve out of Walker's forty-three 

 species appear to belong to it. Aeridium herhac^um, Serville, 

 may conveniently be regarded as the type. 



122. Heteracris cognata. 



Heteracris cognata, Walker, Cat. Derm. Salt., B. M., iv, p. 

 658, n. 6 (1870). 



Hob. Transvaal : Barberton ; Nyasaland : Fort 

 Johnston {Rendall); Natal {G-ueinzius ; B. M. types). 



The disc of the hind femora is infuscated on both sides 

 in the specimen from Barberton, but this is not the case 

 in the types, with which it otherwise agrees very well. 

 Walker's types are rather larger than Mr. Kendall's speci- 

 mens, and the colour of the hind tibiae is indeterminate 

 (probably faded) ; in the latter they are blue, with a broad 

 pale band near the base.
