abbreviated submarginal transverse line, as in the variety of 

 limbalis. I should not be surprised if individuals of your splen- 

 dida should occur with the intermediate band, as in limbalis. 



Dr. Zimmerman coincides with me in thinking that pur- 

 purea, splendida and Umbalis are three true species, and not 

 varieties of one or two species. 



Your Anchomenus collega proves, on comparison with speci- 

 mens from Pennsylvania, where it is quite common, to be the 

 true extensicottis of Say and of Dejean. The Massachusetts 

 species, which heretofore I have supposed might perhaps be the 

 extensicolliS) is not found in Pennsylvania, and must bear the 

 name of proximus, which I proposed for it in the New England 

 Farmer of November 14, 1828. I am told that it is the "J.. 

 Lecontei nov. sp." of the third edition of Dejean's Catalogue. 



A careful comparison of our Northern insects with species 

 from Pennsylvania, will enable me to identify with certainty 

 many of Say's species, respecting which heretofore I have had 

 doubts, and will probably show that in Massachusetts and New 

 Hampshire there are many species closely allied to, but distinct 

 from, their co-species of the Middle and Southern States. This 

 comparison will also enable us to clear up several errors into 

 which Dejean has fallen, from not being sufficiently acquainted 

 with English to read Say's description. For example, ffarpalus 

 agricolus Say, turns out to be the Anisodactylus luctuosus of 

 Dejean ; ffarpalus carbonarius of Say is the Anisodactylus 

 agricolus of Dejean ; and Anisodactylus nigritus of Dejean is a 

 Northern species which Say does not seem to have known.
