120 COLEOPTERA. 



mixed up in Mr. Stephens's cabinet under the same specific 

 title, it results, that Mr. Waterhouse's catalogue conveys 

 a very imperfect notion of Mr. Stephens's views and of the 

 species contained in his Collection. The fact that a species 

 is unaccompanied by any reference whatsoever to Stephens 

 does not, as one would surmise, necessarily imply either 

 that it was not known to and described by Mr. Stephens or 

 that it is not to be found in his Collection, e. g. Achenium 

 depressum, which is well described by Stephens, Illustr., 

 Mand. V., 265, 1, excluding the last paragraph of the de- 

 scription, which refers to A. humile, which he considered to 

 be a variety, and with which it will be found mixed up in 

 his cabinet. Again, in the genus Oligota, Mr. Waterhouse 

 enumerates four species, to none of which does he make the 

 remotest allusion either to the Stephensian works or Collection, 

 and which would naturally induce the belief that the genus 

 was totally unknown to Mr. Stephens and unrepresented in 

 his Collection, an inference scarcely reconcilable with the 

 fact that in the Manual he describes no fewer than six species 

 under that genus, to not one of which is prefixed the sign 

 that he did not possess it, and of all of which exponents 

 exist, therefore, in his Collection. 



Under these circumstances it is obvious that in my sum- 

 mary of the new species of Brachelytra noticed in 1858, 

 faults both of commission and omission are not unlikely to 

 occur. 



Furthermore, I have been under the necessity of passing 

 over two Lists published by Mr. Waterhouse, Proc. Ent. 

 Soc. Lond. 7 Dec. 1857, 96, of the genera Rhizophagus and
