74 Major F. J. S. Parry on 



other characters, renders it amply distinct. It differs from 

 8. Lindenii as follows : — The mandibles are more robust 

 and arcuate, considerably more elevated on the upper 

 surface ; the prothorax much wider, with its punctuation 

 considerably stronger, the posterior angles more rounded ; 

 the elytra are wider at the base, consequently more 

 parallel. The character of the sculpture, especially near 

 the apex, is more strongly vermiculate ; the legs consider- 

 ably more robust, with the denticulation of the tibiae, 

 infinitely more pronounced than in any other species of 

 the genus with which I am at present acquainted. In 

 reference to S. Lindenii, the armature of the four 

 posterior tibiae is entirely wanting. The sparse and 

 irregular character of the pubescence exhibited on the 

 upper surface, in comparison with that existing under- 

 neath, may show, perhaps, only an abnormal condition, 

 caused by friction. The upper surface, when the insect 

 is in its normal state, may probably prove to be villose, 

 perhaps only on the prothorax and mandibles, a condi- 

 tion sometimes to be met with, but rarely, in other allied 

 species. I am indebted to W. Wilson Saunders, Esq. for 

 the opportunity of describing this new insect, as well as 

 others hereafter mentioned.
