PSYCHE. 



I August 1S92. 



[DRAFT OF REPLY BY THOMAS SAY.] 



October 12th, 1S25. 



I thank you much for the specimens 

 of ins. you were so good as to send me, 

 as well as for the agreeable letter which 

 accompanied them ; in the care of Mr. 

 Robinson they all arrived in excellent 

 order. 



The Pollyxenus you met w. is ["per- 

 haps" erased] the P. fasciculatus Nob. 

 if so the species has a wide range. 



Pieris, I have not met w. this sp. 

 before & do not know it, have you both 

 sexes ? 



Limenitis arthemis, Drury, the But- 

 terfly w. a broad white band across ea. 

 wing. 



Lycaena phlceas, var. 



Cicindela formosa. I am surprised 

 to learn that this is f'd in y'r region; 

 I've never met w. it here. I think you 

 will find the green Cicindela to be a 

 variety of C. 6-guttata, I have some 



specimens on which the punctures are 

 very large so as to give the surface a 

 very rough appearance. 



The Craspedosoma must be interest- 

 ing, I have not yet found a sp'n in this 

 country. 



The black Leptura is my L. pubera. 



"The Tipula found in ditches &c" 

 is Ptychoptera clavipes of authors. 



The brown butterfly is my Hip- 

 parchia semidea. I received a mutil- 

 lated specimen from Mr. Nuttall, but 

 yours is in good order. I propose to 

 figure it. in my 3rd or 4th vol. (the 

 marbling of the under sides of hind 

 wing is much as in H. semele, but the 

 dark lines are broader.) 



The Leucospis is a small sp'n of my 

 L. affinis. 



The Prince of Musignano will deliver 

 you this letter if he goes so far as Sa- 

 lem, if not he will put it in the Boston 

 post office. 



Melandrya labiata Nob. 



DESCRIPTIONS OF OESTRID LARVAE TAKEN FROM THE JACK 

 RABBIT AND COTTON-TAIL. 



Our jack-rabbits and cotton-tails are 

 frequently badly infested with bots, but 

 the former are usually the worse in- 

 fested. The jack-rabbit of this region 

 is the Lepus callotis of Wagler ; while, 

 if I am not mistaken, our cotton-tail is 

 the sage hare, Lepus a?'temisia of Bach- 

 man (or possibly L. bachmani Waterh. ) 



Jack-rabbits are sometimes seen with 

 immense, unshapely lumps on their 

 shoulders, sides or backs. Whether 

 or not these are due to bots, I can not

say positively, as I never succeeded in 

 securing a rabbit in this condition. I 

 have been told that when these lumps 

 are cut open, they reveal simply a col- 

 lection of sacs filled with a watery sub- 

 stance, but without bots. 



It may seem strange to record that 

 the jack- rabbit bot is a Dermatobia, 

 while the bot of the cotton-tail is, as a 

 rule a Cuterebra. Such, however, is 

 the case. While I have not observed 

 any instance as yet of the Cuterebra in-
