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

 Mss.' Catal.] may very likely be the quadrimaculatus of Linn^ 

 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 on^, 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 was lately brought. 



HENTZ TO HARRIS.

My conclusion about my 740 [= '•'■ CratacantJius pennsyl- 

 vanieus Dejean," Hentz's mss. Catal.] is that it cannot be 

 ranked as a 3Iorio, of course ; that it is not an Ozcena because 

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

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

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

 it is the connecting link between the Searitides and Harpalus^ 

 or between the Bipartiti and the Thoracici ? 



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

 the under lip of the Upls^ 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 9 , 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 harbatidus 

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