mandibles, head and prothorax assimilating very closely to 

 it, but the sculpture is somewhat coarser, with the posterior 

 angles of the prothorax rounded, slightly reflexed, and not 

 bidentate as in S.pubescens, whilst both the sculpture and 

 colour of the elytra differ conspicuously ; the pubescence 

 of the insect is moreover of a more golden hue. I have 

 named this new species in honour of Dr. Taschenbero-, 

 Professor of Natural History at the University of Halle', 

 to whom, upon the present occasion, I am indebted for 

 much valuable information.

This interesting new species was recently described by 

 Mr. C. Waterhouse, who justly characterizes it as being 

 distinguished fi-om other allied species of the genus by its 

 depressed form and dense pubescence. I have thought it 

 advisable to add a figure of the insect in the present pub- 

 lication, as well as Mr. C. Waterhouse's diagnosis of the 

 species.

Mr. C. Waterhouse's species has been again described, 

 loc. cit.y with other interesting novelties, by Dr. Taschen- 

 berg, to whom I am indebted for the specimen ( ^ ) in my 

 collection. This insect Avas found somewhat profusely at 

 Loja, in Ecuador, by the well-known traveller and botanist 

 Herr Gustav Wallis, of Detmold, who traversed South 

 America during 1860 to 1867, commencing his travels 

 from the mouths of the Amazons, and proceeding through 

 Ecuador and Columbia to Panama, whence he returned 

 to his native country. 



S. Wallisii must therefore yield to the law of priority, 

 as its identity with the type specimen of C. Peruvianus in 

 the British Museum does not admit of the slightest doubt.
