50 Rev. F. D, Morice on male, terminal sc(jmcnts and 



with it. The $ sixth ventral plate resembles that of 

 caspicus, it has pretty long but not very thick penicilli at 

 its lateral angles, a scarious margin, and a smooth pale 

 longitudinal space in the middle of the disc. In both 

 sexes the thorax above has a close and very even (as 

 though shorn) pilosity, paler than in cas'picus, being rather 

 yellowish-brown than fulvous. Beneath, and on the face, 

 propodeum, and legs, the hairs are pure silvery-white. 

 Other characters are given in my Tables. 



The specimens examined, the only ones I have seen, 

 were taken in Algeria by the Rev. A. Eaton, after whom I 

 have named it. 



Radoszkowski's figure (in H. E. S. R., v) of his C. Jcirgi- 

 sicus much resembles the $ of eatoni ; but its wings look 

 very dark, Avhile they are quite clear with pale nervures 

 in eatoni. And his description is so inadequate, that I 

 cannot even be sure to what group even his species really 

 belongs. He described only the $.

A small species from South France kindly communicated 

 to me by its author; and the last known to me of the 

 section with " unnotched stipites." 



In the seventh segment the base reminds me most of 

 caspicus, the apex of ligatus. The armature seems very 

 distinct by the very broad, well-developed " fourreau," with 

 its appearance of a strong narrow (almost linear) chitiniz- 

 ing of its substance near the base of each exterior margin, 

 by the slighter triangular sub-chitinous dilatation which 

 overlies the fourreau, and by the apices of the stipites 

 which have neither the very elongate character of those in 

 hylieiformis and ligatus, nor the short, broad, triangular 

 form of those in caspicus and eatoni. 



Externally the structure of the head and antennee, 

 together with its small size, separate it easily from 

 anything known to me. 



Species with notched stipites 11-35.

This species also I have received from the author. 

 Both in the armature and the seventh ventral plate it 

 seems to have some affinity with the species following, and
