with a short spine before the anus (read female genital aperture), 

 and another with 2 basal knobs on the claw, without that tactile 

 hair, and without the short spine. 



As I already pointed out above (p. 122). \ cons^ki-^v the other iovm 

 as the real Cheletes eruditus (Schrank), whilst the first , on which 

 is based the whole paper of Fumouze and Robin is a quite different 

 species. After scrupulous comparison of this species with my 

 preparation of Cheletes schnelderi I do not hesitate more a moment 

 to declare them identic, notwithstanding the numerous inaccuracies 

 of Robin's drawing, even in the number and situation of the hairs 

 of the ventral side. (N. B. The so-called minute pin before the 

 anal aperture is nothing but the semicircular chitinous beginning 

 of the genital split, distinctly observable in every ? Cheletes!). 



And what to say of Troupeau'?, mite ? I think I have well done 

 to remove it from the real eruditus and to consider it ^.schneideri, 

 on account of his mite is provided with 3 inner protuberances on 

 the base of the palpal claw, and with a long tactile hair in the 

 middle of the dorsal side of the tarsus 1 ; admitting that the trans- 

 parent «olfactoric» hair is not observed by Troupeau.

Male. Length 464 ,,. — Colour pale. — Shape like that of 

 Ch. eruditus (Schrank), but with formidable maxillar palps. — Texture 

 smooth in the shields, finely wrinkled in the unprotected parts. 



Dorsal side (fig. 47) protected by two large and two smaller 

 shields. Anterior dorsal shield very wide, occupying the whole width 

 of the body and more than the half of its length, almost quadran- 

 gular, with rounded anterior angles and rounded edges. The 

 posterior shield much smaller, almost triangular, with rounded 

 anterior angles. Two minute lateral shields. On the anterior shield
