112 ENTOMOLOGICAL NEWS. [April, 



[Here follows a list of 231 species indicated by number] 



Of the several Genera that are included within these numbers 

 your father sent to me all such are are not here enumerated 

 which were all that I sent for at that time, so that all 1 now 

 want are here enumerated, the remaining families I will trou- 

 ble 3'ou for at a future time 



But you must allow me to recompense you for them, I know 

 well the trouble & expense of collecting, and how precious they 

 are when obtained, particularly new species 



I have already commenced describing & my desire to pre- 

 serve the names as given by your Father & yourself, renders 

 me the more anxious to receive these numbers ^ 



I shall be very happy to receive any observations you may 

 favor me with upon these very interesting little animals, either 

 with respect to their arrangement, manners & habits, their life 

 & conversation &c 



I remain very respectfully 



Your Ob,dt Servt

Rev'.^ Jn? Melsheimer 



I had the honor to write you under date of when 

 I acknowledged with thanks the receipt of the insects you were 

 so good as to send me ; & mentioned the mistake that had oc- 

 curred, the blame for which, I am mj^self subject to 1 wrote 



at the same time for other Insects which were particularly 

 enumerated in the letter all of them you would oblige me by 

 by sending as early as convenient to yourself to the Care of 

 "Mr. James Griffiths 

 at Peale's Museum 



Baltimore for Tho? Say

 By this Gentleman who has kindly offered himself, we can 

 at any time transmit to each other Insects &c with the most 



perfect safety as far as his attention can secure them 



I had the pleasure to find a very fine & remarkable new in- 

 sect the other day on the banks of the Wissahickon a few 

 miles from Philad? it is of that singular genus Diopsis of which 



Say's first entomological paper appeared in June, 1817. — W. J. F.
