in my preceding letter. I have one species considerably larger, 

 and closely related to it, which is distinguished from it chiefly 

 by the form of its thorax, which is more convex and is narrower 

 at base. It is from Newbern. I have in all, five species 

 which you have not, if one of them (No. 1004) is not T. badius 

 Say, with the description of which it does not well agree. 

 Besides these I have a Toxicum? [Boros unicolor Say]. I 

 should have no doubt about Its belonging to that genus, were it 

 not that the antenna have a club of only three joints. The 

 other characters, except its elongated form, are those of Tcnc- 

 Irio, or rather those of Upis, as the thorax is narrower than 

 the elytra.

This fall I captured Lamia Ufidator Fabr. It is a beautiful 

 insect. I am inclined to think that his L. nodosa is the same 

 insect, although it is the fourth joint of the antennas which is 

 incrassate. I collected five or six (to me) new species of 

 Clivina, the largest of which, and the most beautiful, seems to 

 be new, certainly not described by Say. Among the Adcpliagi 

 there is an accession in my cabinet of perhaps fifty species, a 

 few among the intermediate families, scarcely one of the Lam- 

 ellicornes, but many heteromerous insects, and a good number 

 of RhyncliopJiora and Longicornes. 



HARRIS TO HENTZ. 



MILTON, September 5, 1829. 



The Carolinian species (of Chremastoclieilus) allied to Hentzii, 

 upon careful examination and comparison with that insect, ap- 

 peared to present characters sufficiently distinct. There is a 

 small white spot on one elytron, which is situated as in Hentzii. 

 The other is effaced. I have mislaid my notes on this species ; 

 but what struck me as the most distinctive character was this:
