their apex prolonged into a process, bent downwards and clothed with short hairs ; 

 from their lower surface is given off a reflexed expanded membrane, convexo- 

 concave, and somewhat fan shaped. A small portion of these membranes appears on 

 either side of the stipites in a dorsal view of the armature, 



May be distinguished at once from H. pnnctatissimus by the colour 

 of the tarsi which are not at all yellow, and the very different form of 

 the genital armature. The ? , which I have never found, would 

 probably be very similar to that sex of the above-mentioned species.

PRE-OCCUPIED NAMES and GENEEA in the MICRO-LEPIDOPTERA. 

 BY THE RIGHT HON. LORD WALSINGHAM, M.A., LL.D., F.R.S., &c. 



Eeferring to Mr. Meyrick's note (Ent. Mo. Mag., XXX, 230 

 [1894)]), I had not overlooked the fact that in profuqella and others of 

 the genus veins 6 and 7 of the hind-wings are from a point or stalked ; 

 indeed, it was pointed out that this was the case by Heinemann 

 (Schm. Deutsch. Tin., 405 [1877]) in silerinella and profuffella, but for 

 the separation of my genus Cataplectica, as stated at the time, I pre- 

 ferred to rely especially upon the difference in the neuration of the 

 fore-wing, in which veins 7 and 8 arise from a common stem, not 

 wishing to express an opinion as to the value of the character 

 presented in the hind-wings. 



I am obliged to Mr. Meyrick for reminding me that the name 

 Seydenia is pre-occupied ; I had a note to that effect, but purposely 

 postponed drawing attention to this until I could send up for execu- 

 tion a very considerable number of its companions among the genera 

 of Micro-Lepidoptera. 



To make the list more complete, I have included those to which 

 Mr. Meyrick has drawn attention. 



The list is in three columns, of which the first contains names 

 pre-occupied, or habitually ascribed to wrong authorship ; the second 

 and third giving the reasons in each case why such names should not 

 be used. 



Where a name is found in the third column, this name should 

 replace that used in the first. 



Where no name appears in the third column it does not 

 necessarily follow that a new name should be given— some hetero-
