 longest, second last the shortest. Bach segment with a trans- 

 verse series of hairs, varying from two to four in number, 

 the external one of each series on segments three to six being very 

 long; there are also several hairs in the posterior lateral angles, 

 increasing in length posteriorly. Each segment with a transverse 

 band extending the full length of segments one to six inclusive, 

 and partially divided on the meson, the division being most 

 complete forward and diminishing in extent posteriorly ; in the 

 seventh and eighth segments the bands are narrowed and completely 

 divided. Last segment rounded, entire, with numerous marginal,

Nirmus rufus, Nitzsch. 



A single male from Corvus sharpi (Yarkand, Chinese Tur-

This specimen shows such differences from the description of 

 the type of the species that it should probably be given a 

 varietal name.

 This species belongs with Piaget's crow-infesting group, among 

 which are several species with curiously deformed abdominal 

 segments, and with two prominent groups of three or four short 

 spines on the lower side of the first or second abdominal segments. 

 Several of these species are: M. trinoton, Piaget, M. anathorax, 

 Nitzsch, and M. mesoleucuni , Nitzsch. The present species differs 

 from these in the form of the metathorax, the posterior margin of 

 which is strongly convex, as well as in the shape of the abdominal
