rather in the middle than at either end of the series of families 

 which form this group. 



The adoption of Mr. Meyriek's system, of course, involved 

 great changes in generic nomenclature, for which he had given no 

 reasons. In some cases where his alterations have been accepted, 

 the reasons for such acceptance are here set forth : in ail cases 

 where I have been unable to accept his generic names I have 

 fully discussed and explained how the names here adopted have 

 been arrived at. For any further explanation on this point, rlie 

 reader may now refer to the code of rules compiled by Mr. Durranc 

 and myself, which has lately been published by Messrs. Longmans 

 under the title 'Rules for regulating Nomenclature with a view 

 to secure a strict application of the Law of Priority in Entomo- 

 logical Work.' 



In my previous paper 132 species were enumerated as occurring 

 in the West Indies : of these 10 were simply mentioned as " sp." ; 

 these are now deducted, as are also Scoptotioma tipuloides, AVlsm. 

 (now regarded as belonging to the Pyralidina) ; Pterophorus asj>ih>- 

 dactylus, Wkr. (now regarded as a worn specimen of P. ac/rapho- 

 d«ctylus,Wkv.); Ccmogenes pusilla (Z.), AVlsm. (wrongly identified, 

 and described in the following pages as Hypoclopus parvus, sp.u.); 

 Psecadia adustella, Z. ( = Tamarrha gelidella,~Wls.r.) ; P&ecadia ingri- 

 cella, Mschl. ( = Ethmia confusella, Wkr.) ; Cosmopteryx lespedezce, 

 AVlsm. (= Cosmopteryx attenuatella, Wkr. : Walker referred this 

 species to Gelechia, which must be my excuse for the creation 

 of the synonym) ; Cosmopteryx gemmiferella (Clem. ?), Mschl. 

 (recorded with doubt by Moschler, and here omitted as being 

 probably synonymous with attenuatella, Wkr.). These deductions 

 reduce my former list to 115 species (132 — 10 — 7). To this total 

 is now added 34 species already described, and these, together 

 with 153 new species, raise the total of the West-Indian Micro- 

 Lepidoptera to 302 species (115 + 34-1-153). Nineteen genera 

 are characterized as new. 



The species recorded from each of the islands are as follows : — 

 Cuba, 23; Jamaica, 31 : Haiti (or San Domingo), 50 ; Portorico, 37 ; 

 St. Croix, 57 ; St. Thomas, 114 ; St. Jan, 3 ; St. Martin, 1 ; Guade- 

 loupe, 1 ; Dominica, 7 ; Martinique, 1 ; St. Lucia, 2 ; St. Vincent, 

 43; Grenada, 00; Trinidad, 8; Curacao, 1. — West Indies, 302. 



Of these species, 27 occur in the United States, 4 in Central 

 America, and 28 in South America ; 5 are found also in Europe, 

 3 in India and also in other parts of Asia, while one extends to 

 Malaysia; 5 occur in Australia, and 4 in Africa. The larvae of 

 49 species are known, of which number 34 have been bred in the 

 West Indies. 



What is now specially wanted is some knowledge of the Micros 

 of the more northern islands stretching towards the coast of 

 Florida, as well as from the peninsula of Florida itself. There is 

 strong reason to believe that very beautiful and distinct forms of 

 these insects are to be found in Cuba, Portorico, and Haiti, and 

 also in Florida — such as have been already received include some
