It is highly probable that this description was intended to de- 

 signate an insect very similar to the C. puactulata, perhaps the 

 same, or only a variety of it, for it is as characteristic of that 

 species as it can be of any other. 



[From Transactions of the American Philosophical Society, New Series, 

 Vol. 2, No. 1, 1823.] 



Descriptions of Insects of the Families of CARABICI and HYDEOCAN- 

 THARI of Latreille, inhabiting North America.* 



Read August 26tb, 1819. 



In the first volume of the New Series of the Transactions of 

 this Society, I commenced the regular description of our North 

 American insects, by a Monograph of the indigenous Clcindeletsc ; 

 a Linnaean genus which occupies the first station in the improved 

 classification of Latreille. 



I now proceed to lay before the Society descriptions of such 

 of our native insects, as were included by Linne, in his three 

 genera, Carahus, Di/tiscus, and Gyrinus. The two former of 

 these, but more particularly the first, are now considered as great 

 families, constituting numerous genera, and agreeably to the or> 

 der in which I have enumerated them, immediately succeeding 

 the Cicindeletse., in the system which I have adopted. 



■»The title page of the 2d vol. of the New Series of these Transactions 

 bears date 1825, which was the time of completion of the volume, but 

 the late Dr. T. W. Harris informed me in a letter, that he received from 

 Mr. Say a copy of this paper, with the following addition to the title : — 

 "Printed and published by Abraham Small, 1823." This, of course, 

 gives Say's names precedence of those published by Germar in his Sp. 

 Ins. Nov. in 1825.— Lec. 

 1823.]
