I think it ought to be placed near the G-eometridce. Boisduval's 

 American (?) Colias Edusa is not found here. 



DOUBL^DAY TO HARRIS. 



EPPING, May 27, 1840. 



I have cursorily examined Abbot's drawings in the British 

 Museum. They are in seventeen large, thick, quarto vol- 

 umes. Of these, three are Lepidoptera without larvae, two 

 with larvae, etc. They contain, too, a vast number of Ab- 

 bot's manuscripts. These five volumes I have examined. I 

 may mention a few things. Melitcea Ismeria larva. " Feeds on 

 crosswort. Frequents the oak woods of Burke County, but is 

 not common. Caterpillar suspended itself May 16th, changed 

 to chrysalid May 17th. Butterfly appeared May 26th." Do you 

 know this species ? The name I think is Boisduval's. The draw- 

 ing has no name to it. Polyommatus Tarquinius. " Larva on 

 arrow- wood and alder. Frequents swamps, but rare ; most com- 

 mon in Big Ogeechee Swamp. Larva suspended itself on the 

 12th of April ; became a chrysalis on the 14th. Butterfly ap- 

 peared Apr. 25th." There is a species of Pygcera closely allied 

 to, but yet distinct from, what I have called ministra ; this is also 

 figured with a different larva. Probably mine (taken at Tren- 

 ton Falls) is the more Northern species. Of the genus Lima- 

 codes there are some most interesting species quite new to me. 

 A few I have of Abbot's own collecting. The Oiketicus I am 

 now engraving from Raddon's drawings, and have its history 

 at length. I shall print this as soon as the plate is ready. I 

 observe a drawing of C. Philodice, but he mentions that it is 

 very rare. I did not know it occurred so far south in the low 

 grounds. There is a large and beautiful Polyommatus allied 

 apparently to our European species, P. Ads W. V., Pap. 

 Cymon of Lewin. P. Protodice and A. Crenutia are drawn also 

 without larvae. The former marked very rare ; the latter "oak
