endeavored to make out the genus by these works, but do not 

 find the insect in question to agree entirely with the generical 

 definitions taken together from both these works. I have 

 compared my insect, and find it comes nearest to Anacampsis 

 nivella and blattariella (which Mr. Curtis sent me) in generic 

 characters. The last joint of the palpi, however, is somewhat 

 longer in my insect than in the two species last named. You 

 will perceive that the form of the hinder wings of my insect is 

 peculiar, and resembles that of -these two species of Anacampsis. 

 I have tried my insect particularly for the genera Anacampsis, 

 Laverna, Cleodora, Acompsia, and Ostyages, as defined by West- 

 wood. These authors say of Anacampsis, "tongue shorter than 

 palpi " ; in my insect it is much longer. Of Laverna they say, 

 "palpi, second and third joints of equal length" ; in my insects 

 the third joint is., the longest. Of Cleodora they say " palpi 

 slightly recurved"; in my insect they are more than slightly 

 recurved. Of Anacampsis {Butalis in part) they say, " hind 

 wings broad, not attenuated at the outer angle " ; in my insect 

 the hind wings are narrow, and are suddenly attenuated at the 

 outer angle. Of Ostyages {Butalis in part) they say, " max- 

 illce very short," etc. ; the maxillae or tongue in my insects is 

 half the length of the antenna?. 



I have reason to believe that this insect under consideration 

 inhabits Europe ; that it was known and described there more 

 than eighty years ago, and that it was introduced thence into 

 America, where it has multiplied to an alarming extent.

To-day Cairtis called here, and on looking at Duponchel, 

 Supplement, 85, we find that your insect seems to be near, if 

 not identical with, the grain moth of France described by 

 Reaumur.- It is the CEcoplwra granella of some, the Butalis
