African Micro-Lcpidoptera. 101 



258261 (1877) ) had the effect of supplanting his 

 original descriptions, and served rather to obscure the 

 classification than to render it more correct or more easy 

 of comprehension. Cryptolechia straminella having been 

 described originally as the type of the genus (Hand. 

 Kongl. Svensk. Vet.-Ak., 1852, 107), he subsequently 

 recharacterised the same genus in an expanded form, 

 making Depresmria (Volucra) flava, from South America, 

 the typical species (Lin. Ent., IX., 3535 (1854) ), in- 

 correctly using the expression " venae simplices," whereas 

 veins 7 and 8 of the fore wings in that species are from 

 a common stem, and, in fact, the species agrees in all 

 points with straminella. 



In the Horse Soc. Ent. Boss., XIII., 259 (1877), he 

 removed C. straminella to MacJiimia, retaining^a^a in 

 Cryptolechia in defiance of the fact that their characters 

 are identical, and differ from tentoriferella, Clem., the 

 type of Machimia, in the remoteness, at its origin, of 

 vein 2 from vein 3, which arises at the lower angle of 

 the cell of the fore wings. 



With regard to Stenoma, which was described by 

 Zeller (Isis, 1839, 195), and included griseanum, litura, 

 and bicolor, alike in structure and neuration ; in the 

 Lin. Ent., IX., 391 3 (1854), he identified griseanum as 

 walchiana, Cram., and founded the genus Antceotricha 

 for its reception, together with some allied species. He 

 then removed litura and bicolor to Cryptolechia (pre- 

 sumably Cryptolechia No. 2), from which they differ, as 

 from No. 1, in having veins 7 and 8 of the fore wings, 

 as also 6 and 7 of the hind wings, separate, corre- 

 sponding therefore to his statement "vena simplices" 

 but not to his selected type. In the Horse Soc. Ent. 

 Boss., XIII., 258-261 (1877), he still further extended 

 his genus Cryptolechia, including many modified forms 

 as subgenera. He here resuscitated Stenoma (of which, 

 as I have shown, the original type was griseanum = 

 walchiana), and, having got rid of the other species 

 placed in it in the first instance, he left litura as the type 

 at the head of his list, placing bicolor in a different sub- 

 section, and omitting griseanum altogether, although the 

 three are identical in structure. 



In pointing out these inconsistencies I have had the 



freat advantage of possessing nearly the whole series of 

 eller's generic types, in many cases the actual speci-
