liant insects I ever saw ; it is very common now, and I will 

 send you specimens. In other respects it has the habitus of C. 

 marginalis, and in its form differs from it only in having its 

 thorax narrow and slender. 



Can you furnish me with the descriptions of two species of 

 a new subgenus of Aranea^ published by Rafinesque in Ken- 

 tucky? I have not his paper, but you may possibly find it 

 in Boston; I forget even its title. He blundered into the 

 truth in that instance, and I ought to quote him. Insects 

 begin to swarm here, and few hours pass without making 

 some discovery. I have now five or six species of Clytus not 

 determined yet ; one is beautiful. Dipterous insects are nu- 

 merous, and I have beautiful specimens which I can hardly 

 place in any genus, but it may be owing to my want of knowl- 

 edge of that class, which I have but just begun to study. But 

 what will you say when I tell you I have found three individu- 

 als of a fourth species of Ghremastocheilus. It may prove to be 

 the 0. castanece, however, as it is entirely black, and the thorax 

 somewhat narrower before. I will send you a design if you 

 wish, and would have done so were it not that it would be too 

 late for your paper. 



I found to-day a fine Nbtoxus, a large immaculate species, 

 with a yellow horn, but I lost it ; I have no doubt I may find 

 many to-morrow ; it seems that insects of this genus, as of 

 Lijtta^ feed on vegetables. 



IIARRIS TO HENTZ. 



Milton, April 9, 1827, 



Many thanks, my dear sir, for your prompt reply to my last. 

 Your history of the habits of Lamia amputafor was new and 

 interesting to me ; it differs from all others of the Capricorn 

 tribe with which I am as yet acquainted, and will probably 

 serve as a clue to others of the genus.
