elevated and conical ; tlie metathorax has at its base, near 

 the post-scutellura, a small shining tubercle, from which, 

 on each side, two divergent carinre run to the lateral mar- 

 gins, which are also edged with an elevated carina ; all the 

 coxa3, the intermediate femora beneath, and the posterior 

 pair, black, tip of the latter yellow ; abdomen black, smooth 

 and slightly shining. 



This species resembles Tragus pepsoides, from North 

 China, described by myself in the Transactions of the 

 Entomological Society of London, vol. ii. (1852); it is, 

 I consider, on a careful comparison of the two insects, 

 distinct ; the areolet of the anterior wing is much larger, 

 the metathorax longer, and the basal segment of the 

 abdomen narrower, and differently sculptured ; its abdomen 

 is not variegated with ferruginous colour.
