a. Adult. Kordofan. 



h. Adult. Africa. From Mr. Frank's Collection as E. guhieense (?). 

 c. Adult : not good state. Africa. From the stomach of a Lepfo- 

 deira riifescem. 



The separation of this species from the Indian Diplopelma and 

 the American Engystoma appears to be the more justified, as, besides 

 the different structure of the ear, it diifers in ha^dng a perfect cla- 

 v-icula, entirely wanting in the genera mentioned. 



To this genus perhaps belongs Engystoma marmoratum, Peters, 

 Wiegm. Arch, 1855, p. 58. Mozambique.
