^2S2 NATURAL HISTORY OF NORTH AMERICA, 



like ours, and these are abundant. There are some very in- 

 teresting things alHed to Polypogon and Botii^. 



Diptera are not numerous, with the exception of some few 

 kinds ; I nowhere found the swarms of small Diptera which 

 we so frequently meet with in England : musquitoes rarely 

 came to the house, but there were many in the wet woods. 



In Hemiptera, the Cimicites and Cicadites were abundant; 

 but owing to so many of them being in the larva state, up to 

 the time of my leaving Trenton for the west, I did not get so 

 many of them as I could have wished ; there were also two 

 things which combined to lessen my collection in this and 

 some other classes : the abundance of nocturnal Lepidoptera, 

 and the scarcity of Coleoptera. At night I sometimes, with the 

 aid of my friends, obtained so many moths, that it took me four 

 or five hours the next morning to spread them. Then I had to 

 take others off the boards, ticket them, and p\it them away ; 

 this took much time : then the scarcity of Coleoptera often 

 made me spend the whole morning in searching for them, 

 most laboriously, and to very little purpose. 



Hymenoptera. These I collected very carefully. There 

 was by the side of one of Mr. Moore's fields a sloping bank, 

 covered with raspberry bushes ; when these were in flower 

 this was a grand place for bees, and the fossorial Hipnenoptera, 

 though I took but few of the finer kinds of the latter. Bees 

 were not nearly so numerous as R. Foster afterwards found 

 them in Ohio; however, there are among them some very inte- 

 resting things. Of Tenthredinites I rarely lost an individual. 

 I expected to have taken many Ichieumonites, but was dis- 

 appointed ; there are, nevertheless, some fine species about 

 Trenton. Of Chalcidites I found scarcely any. . fl 



You know I left Trenton towards the end of August, to 

 proceed towards tlie west. In one respect I erred; the main 

 body of butterflies had not appeared at Trenton, but when I 

 reached a warmer latitude many species were over. As 1 did 

 not intend to spend much time in any one place, I did not go 

 prepared to do much in collecting ; however, when 1 arrived 

 at Cincinnati, 1 could not help staying a day or two for this 

 purpose. My first excursion was to the Kentucky shore of \ 

 the Ohio. I crossed the ferry, and strolled along the shore 

 to where Mr. Bullock once lived ; then I turned oft' by a little 

 brook into the woods. The trees were large: one hundred feet
