tlian tlie typical Indian vlnosa, but another specimen f from 

 the same locality as loingatei is much nearer to vinosa in its 

 dimensions and coloration, which prevent me from regarding 

 wingatei as a northern subspecies of vinosa. Specimens from 

 Burma are also somewhat smaller than those from India, 

 but of tlie same coloration. 



Geographical distr'ihution. The type of vinosa is from 

 North Bengal. Other specimens in the British Museum are 

 from Mohanpar and Pakur, Bengal ; Maymyo, Burma ; 

 Aijal, Lushai Hills^ Assam ; Yang-tse-kiang, China.

 reclinate, prominent, and somewhat dilated between the an- 

 tennae, flat, punctured, impressed below the ocellum, lowered 

 and disappearing before the clypeus. Antennae reaching 

 beyond the base of the hind femora. Fastigium of the vertex 

 strongly sloping, forming a broad curve with the frontal 

 ridge, slightly impressed, not marginate. Distance between 

 the eyes slightly broader than the frontal ridge between the 

 antennae and distinctly narrower than the horizontal diameter 

 of an eye. Eyes strongly prominent sideways ; their height 

 less than twice the horizontal diameter, which is subequal 

 to the height of the subocular sulcus. Pronotum with 

 the prozona perfectly rounded and swollen on the lateral 

 lobes ; the metazona almost flat ; median keel fine, linear, 

 interrupted by feeble transverse sulci ; the whole surface 

 rugulose ; hind angle about 90°, rounded. Prosternal

 coriaceous, coarsely and iriegularly reticulated ; the apex

 distinctly serrate. Hind tibiae thick, armed with eight outer 

 and nine inner stout spines. Male cerci straight, compres.^ed,

 other by the above characters. Only one species is known,
