Your 725 [= "Stenocorus quadrigeminatus Say," Hentz's 

 MSS. CataL] may very likely be Ihe quadrimaculatus of Linne" 

 and others, which species was found in Jamaica by Sloan. It is, 

 however, not a little remarkable, if your insect is identical with 

 the Linngean one, that the same species should be found both in 

 the warm regions and forests of South America, and in the 

 boreal forests of Maine, from whence a specimen belonging to 

 a friend of mine Avas lately brought.

My conclusion about my 740 [= " Cratacanthus pennsyl- 

 vanicus Dejean," Hentz's MSS. CataL] is that it cannot be 

 ranked as a Morio, of course ; that it is not an Ozcena because 

 the antennas are not sensibly larger at their extremity, and the 

 body is not flattened ; but that it must be related to both these 

 genei'a. Do you not think it must form a new genus, and that 

 it is the connecting link between the Scaritides and Harpalus, 

 or between the Bipartite and the Tkoracici ? 



I had, as you supposed, overlooked the beard depending from 

 the under lip of the Upis, because I could not see (and I con- 

 fess I cannot now see) any difference between those having a 

 beard and those having none. On receiving your letter, I 

 emptied the vial containing my duplicates, and was glad to find 

 as many as nine. I examined them all with great care, and 

 found six $ and three ? , but that which I had strongly 

 suspected before was realized. All the $ were bearded, and 

 the three 9 were destitute of that character. It would seem 

 by your letter that bearded ones are not found in Massachu- 

 setts ; that point ought to be ascertained ; it is certain that, 

 according to my observation here, Upis Icevis and larbatulus 

 must be the two sexes of the same species, if my specimens
