Here come more than lialf the number of the !-i)ecies of Aijoristidae, and most 

 of the ^^l)ec•ie!^ seem structurally so closely allied that it is very ditiieult to give a 

 di-limitatiou of the genera.

Hainpson, Moths of India II. \>. 149 (1894), diflferentiates A&jocero, Latr, and 

 Mimeusemia Butl. from the other Indian Agaristido.e by the absence of vein 5 from 

 I he hindwings. This .'■tatement, I think, is eiToneous. In all our sj)ecimens of 

 Aeijocera and Mimeusemia that vein is jjresent. Karsch's Aetiiiopian genus 

 Aegocerophis, Ent. Xachr. 1895. j). 348, said to be distinguishable from Aefjocera 

 Latr. by the presence of vein 5 on the hindwings, must accordingly sink as a synonym. 



Aegocera norma Karsch, I.e., is, as the author has already suggested, the same 

 i\9 A. affi-nis Druce, Ent. M. Mag. XX. p. 1.9.5 (1883), according to the dpscrii>tion 

 and figure of norma and the type-specimen of afhnis Druce. The middle and hinder 

 tibiae of affinia Uruce and fervida Wlk. are on the upperside clothed with long hairs. 



In the Tring Museum is a male of Misa memnonia Karsch, I.e., from Katiiurst, 

 ^^'est Africa, which agrees perfectly with Karsch's description and figure of the 

 female, but has the white baud on the forewings above of even width. 



Of Miaa deliela (Butl.), described as a Massaga and .standing under tiiis genus 

 in Kirby's Catalogue, we have four males and thi-ee females from Accra, (jold 

 Coast. lihe^K females, which structurally differ from i\\e males in the slender and 

 long terminal joint of the palpi, agree well with those desci-ibed (as (piery fem/des of 

 delicia) by Aurivillius in Ent. Tidskr. 1892. p. 186, and confirm the statement of 

 the learned author that in the female of delicia the outer edge of the band on the 

 forewings is not strongly augulate, and that the band on the hindwings is wider than 

 in the other sex. 



Karsch, I.e., p. 348, says of his new genus Mitophrys : " N'ein 2 of the hindwings 

 originating very close to vein 3." This statement, I think, is incorrect, as it does not 

 apply to the type of the genus, .1/. 'ineuete (Cram.), tbe second ])artition of median 

 nervure being longer than the lower discocellnlar veinlet in this insect, while in all 

 the other .-species refen-ed to Mitophrys bv the author, as far as 1 could examine them, 

 that partition is much shorter than the veinlet [trimeai (Keld.), tricolor (Druce), 

 tigrina (Druce), halans Karsch] ; M. rvhidu (Feld.) agi-ees in this re.spect with 

 nienete (Cram.). The forehead of the males of Mitophrys Karscli is said by Kar-sch 

 to be narrowed behind. This, again, is not correct, as it does not apply to the tvpe 

 of the genus, M. menete (Cram.). .Moreover, the narrowed forehead is met with in 

 the males of several species which are referred by Karsch to Aegoceropsis Karsch = 

 Aegoeei-a l.,atr., namely in A. norma Karsch (tyi)e of Aegocfropsis Karsch, and = 

 iiffvivis Druce_), fervida Wlk., ohliqua Mab., and also in the Indian Aegocera 

 bimacida Wlk., not in A. venulia (Cram.) and rectilinea Boisd. The third and last 

 character by which Mitophrys is differentiated by the author from the allied genera 

 is the slenderness of the antennae. As, however, the antennae of Aegocera venidia 

 (Cram.) iiml rectilinea, Boisd. are in either .<ex decidedly thicker llian in A.ferviila 

 Wlk. and oliiif/iia Mab., it is very difficult to draw a parting line between sections 

 13 and 18 of Karsch's key to the Aethiopian genera, and we are, in fact, i|uite at 

 a loss to say whether the new sj)ecies described below stands better in Mitophrys 

 Karscli or in Aegocera Latr. There may be generic differences between the type-
