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

 which form this group. 



The adoption of Mr. Meyrick'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 all cases 

 where I ha\e 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, the 

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

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

 under the title ' Eules for regulating Xomenclatiu'e 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 Scoptonoma tipuloides, Wlsm. 

 (now regarded as belonging to the Pyralidina) ; PterojjJiorus fispiln- 

 dactylus, Wkr. (now regarded as a worn specimen of P. aijraphn- 

 dactyluSjWkr.) ; Ccenogenes pusilla (Z.), Wlsm. (wrongly identitied, 

 and described in the following pages as Hypoclojms parvus, sp.n.); 

 Psecadia adustella, Z. (= Tatnarrha gelidella,Wkr.) ; Psecadia iiujri- 

 cella, Mschl. {:=Ethmia confusella, Wkr.) ; Cosmoptery.v lespedezce, 

 Wlsm. (= C'osmopterijx attemiatella, Wkv. : Walker referred this 

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

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

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

 probably synonymous with attenuatella, Wkr.). These deductions 

 reduce my former list to llo 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 + 153). ]S^ineteen 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, 60; Trinidad, 8 ; Curagao, 1. — West Ij^dies, 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 AustraUa, 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
