in the Dictionnaire classique d'histoire naturelle, article Mo- 

 rion, that I think it probable that it was taken from my insect. 

 The antennae are considerably flattened in the middle, so as to 

 appear larger in one direction ; and the tarsi of the third pair 

 of legs are much more robust, and thicker than the rest in both 

 sexes, characters which, with the preceding one, have escaped 

 the notice of Mr. Say, and yet. are important ; for the last, if 

 common to all the species of this genus, ought to be considered 

 generic, as it is not a common one. 



March 8th. 



No. 814 [814 Hentz's MSS. Catal. = = Modes ? fragilis] I 

 agree with you in thinking nearer Dascillus than Elodes, as the 

 mandibles are not much concealed under the labrum, but the 

 last joint of the palpi is not what could be called "tronque ou 

 tres obtus." 



I have now no less than six distinct species congeneric with 

 No. 807. [807 Hentz's MSS. Catal. = = Mycetopliayus punctatus 

 Say.] When you see them all I think you will be convinced 

 that they are distinct from Mycetopliayus Fabr. By the by, 

 what genus of Latreille do you mean ? Is it Eustrophus ? If 

 that be the case, I think I have three species to which the name 

 applies better. One of them you marked JEustrophus bicolor? 

 To thsse the characters given in the Dictionnaire classique 

 d'histoire naturelle "tetc tres pcncliee" applies very well. I 

 have two more species to which all the characters of Eustrof>lius 

 apply except this, " et dont aucun des articles" (speaking of 

 the antennae) cl partir du 3 me n'est lenticulaire*'; they having 

 slightly perforate and moniliform antennae. These five species 

 have the body more or less attenuated behind. But besides 

 these I have two species, one of which, No. 448 [448 Hentz's 

 MSS. Catal.=D%?em bicolor ? Fabr.] you have. I had marked 

 that one M. bicolor Fabr., and the other M. flavipcs. They are 

 both nearer Diaperis than any of those mentioned above.
