 Mr. Matthews, having now dissected the organs of the 

 mouth of the insect to which the above quotations refer, and 

 finding them exactly similar to the corresponding parts in 

 undoubted members of the genus Trichopteryx, save certain 

 slight (and, in his opinion, only specific) differences in the 

 labrum and maxillary palpi, comes to the conclusion that 

 Thomson's genus JBoeocrara must fall to the ground. The 

 anatomy of the underside and shape and neuration of the 

 wing appear to be alike in this insect and the most typical 

 Trichopteryx ; in which genus Thomson's character of the 

 margined sides of the thorax seems almost to be universal. 



Mr. Matthews rejects the name Thomsoni proposed for the 

 species above referred to by Dr. Sharp^ as Mulsant had long 

 before the publication of the 2nd vol. of the Ent. Mo. Mag. 

 described it under the name of Ptillum variolosum ; a fact 

 detected by Dr. Sharp soon after he had proposed to give 

 Thomson's name to the insect which that author had origi- 

 ginally described under the name littoralis, already occupied 

 by Motschulsky for another allied species. 



Mr. Matthews suggests the possibility of a doubt as to 

 whether the British examples be really referable to th& 

 J5. littoralis of Thomson, on account of his not having yet 

 obtained from the latter a type of his insect. 



I have deferred noticing the second specie? of Eros men»
