as to the form of the apical spot in his species ; and the legs 

 appear very short in his figure in consequence of their being 

 very much retracted. Should, however, these differences actu- 

 ally exist, I can scarcely consider them otherwise than as indi- 

 cative of a variety, and not of a distinct species ; since in form, 

 colour, and indeed in all other essential specific characters, 

 Dr. Horsfield's insect certainly appears to agree with that of 

 Swederus. If, on the contrary, it should ultimately be ascer- 

 tained that this insect is specifically distinct from the C. latipes, 

 I propose that a specific name should be given to it commemo- 

 rative of its learned capturer, by whose researches so many 

 interesting novelties have been added to our zoological trea- 

 sures, designating it consequently Cerapt. Horsfieldii, Westw.
