there are in addition one or two shorter spines on segments 3 and 4, at 

 a very short distance from the supra-lateral row. The legs are very 

 long, the femora spineless ; the upper groove of the intermediate 

 tibiae has two small inner spines (juv.), or the spines are quite 

 obliterated in the adult. In two adults the coriaceous pronotum is 

 very pale, and has a few small black dots between the second lateral 

 and the discoidal spines, three between the two of the postero-lateral 

 part, and two between the two discoidal spines. In a juvenile example 

 the discoidal part of the prouotum is fuscous, and the posterior closely 

 spotted with black granules. 



Length of body (adult) 33-41 mm. ; of pronotum 18 mm. ; of hind 

 femur 28 mm. ; of hind tibiae 32 mm.

Schaum described in 1853 as Hetrodes petersi a species for which 

 Karsch founded the present genus ulteriorly. In spite of the excellent 

 figure given in Peters' Reis. u. Mossamb. Insekten. pi. vii, fig. 7, there 

 is some doubt still as to the identity of H. petersi ; Gerstaeker 

 described E. epliippiatus in 1869, and figured it in Decken's Reis. in 

 Ost. Afric. v, 1873, p. 119, pi. 7, fig. 7. Lucas in 1885 described a 

 species from the Zambesi, E. durandi ; and E. bloyeti from Kondoa, 

 Equatorial Africa. Senor J. Bolivar in 1881 added a fifth species, 

 E. obuncus from Angola. 



In 1913 Dr. T. Sjostedt made known two other species, E. matabe- 

 lensis from Southern Rhodesia, and E. carolinus from German East 

 Africa, between Tanganyika and Lake Albert Edward. I am adding 

 three South African kinds to the total number, making it ten. 



All these species are much alike in general appearance as well as in 

 coloration, and the great difference in the size of adults makes 

 it somewhat difficult to attach much importance to the sculpture 

 of the prouotum. The number of spines in the fore and intermediate 

 tibiae is, however, a good guide, if care be taken to eliminate certain 

 aberrations, i. e. an additional, not always rudimentary spine in one of. 

 the tibiae, occasionally in the intermediate and posterior; but it is easy 

 to notice the aberration by its asymmetrical position. In the fore legs, 

 however, the number of spines is constant, and I found the two rows 

 to be always symmetrical in the forty-three examples of this genus 

 examined by me.
