Mr. Curtis's opinion as to the genus, without any information 

 whether the species was known. Is not the Angoumois moth 

 in the British Cabinets ? You state that Mr. Curtis refers 

 my insect to " a section of Anacampsis formed by Curtis into 

 his genus Lucerna, and refer me to his figure of L. ocliraceella^ 

 a species allied," etc., in plate 735 of Curtis's British Entomol- 

 ogy. This work is not to be found here ; and moreover the 

 genus Lucerna and the species ocliraceella are not contained in 

 Curtis's Catalogue, of which he sent a copy to the Library. 

 Have you not made a mistake in the name ? In Westwood's 

 Synopsis of Genera, annexed to his Introduction, p. 110, I 

 find the genus Laverna Curt, characterized ; and in Hum- 

 phrey and Westwood's British Moths, Vol. II, p. 188, under 

 Anacampsis sarcitel/a, I find this note. "Mr. Curtis forms 

 this, marmorea, air a and ocJiracella (ocliraceella ? ) into the 

 genus Laverna" Westvvood and Humphrey do not give any 

 description of their so-called ocfiracella ; and as to the notori- 

 ous Angoumois moth (or by whatever name entomologists 

 please to call it), it does not figure, and is not noticed in the 

 " British Moths." Well, I suppose Duponchel will have it in 

 due time ; but I do not want to see what he may say, before 

 the opinion of the English Entomologists comes to hand. He 

 alludes to it as a species not yet before him in good state under 

 the name of " Alucite des grains." Le"p. de France, T. xi, p. 

 450, putting it in the genus CEcopJiora. 



The habits of our "Fly-weevil " agree exactly with those of 

 the Angoumois moth as described by Reaumur, Duhamel and 

 Tillet. As you may not have my old letter at hand, and as the 

 references in my treatise were not full enough, allow me again 

 to disentangle the synonymy of the European moth in question.
