(Druce). and the new species deseribod helow, the antennae are also not tliickened 

 towards apex, and these species differ, moreover, from typical I'haluenoides in the 

 middle and hinder tibiae, though not naked, bearing no tuftlike clothing of long 

 hairs in the middle. Phalaenoiiles roeheri (Kibbe), milete (Cram.), nnUalvs (Wlk.), 

 conferhis (^^'lk.), all under Phalaenoidcs in Kirby's Catalogue, and Episteme parjeji- 

 stecherl (Rub.) of Kirby's Cat., must be referred to Ophthalmis Hb. on account of 

 the slender and naked midille and hinder legs which they have in common with 

 0. lincea (Cram.). 



Phalaenoidea ajjinis Boisd. will in I'ntnre come into another (new) genns : tlie 

 antennae are in the S feebly, but visibly, biserially .serrate ; those of the ? appear to 

 be simple and setiform, as in PA. fiunebris ]\Ioore. 



The male of Phala&noides albamedia (Luc), Proc. Linn. Soc. X S. HVi/ra (2). 

 VI. p. 301 (1891) (Brisbane), has a peculiar striilulating organ which reminds one 

 of that of Hecatesia Boisd., but is situate on the hindwings. Within and before the 

 cell of the hindwings, along the subcostal nervure, the membrane of the wing is 

 dilated, denuded on the underside, where it forms a deep furrow, covered with one 

 layer of scales only on the upperside, and transversely ribbed like the vitreou.s mark 

 in Hecatesiii 6 ; on the forewing there is before and behind the median nervure 

 a similar, but much less developed, organ. By examining the legs of this species 

 I found that the first joint of the hinder tarsi is much thicker in the cJ than in 

 the ?, and is provided above, a little towards the inner side, with a row of obviously 

 raised transverse ridges, which I did not meet with in the ? , nor anywhere else 

 amongst Agaristidas, and which, when pressed during flight against the ribbed 

 membrane of the viti-eous mark, might very well serve to produce a buzzing sound 

 similar to that observed by Meyrick in Hecatesia fenestrata Boisd. (see Hampson, 

 P. Z. S. 1892. p. 190). In consequence of the development of that stridulating 

 organ the anterior part of the cell to the hindwings (between longitudinal fold and 

 subco.stal nervure) is broader than in other Agaristidae, and hence the u[)per disco- 

 cellular veinlet longer than the lower one. Notwithstanding that in the other sex the 

 stridulating organ is entirely absent, the lower discocellular veinlet to the hindwings 

 is also here visibly shorter than the upper one. a character which one might suppose 

 to be inherited from the male, or, as iu the d of Ph. glycinae (Don.) without stridu- 

 lating organ the lower discocellular veinlet is likewise, though almo.st imperceptibly, 

 shorter than the upper one, at least to be influenced by the presence, in J, of that 

 vitreous mark. 



Vein 5 of the hindwings of albamedia (Luc.) is parallel to vein 4; it is rather 

 cur\'ed at two-thirds of its length from the outer margin, and thence becomes 

 straight. The hindtibiae are without long hairs in the middle. The ba.sal third 

 of the co.stal margin of the forewings is in either sex more dilated than in any other 

 species of Phalaeaoides Lewin. The spines of the fir.st joint of the hinder tarsi are 

 less developed in the 6 than in the ?. K. .1.

Differs from P. golJu-: (Drucej, An,,. Mag. N. H. (G). X\\. p. 21 (1894), in 

 the following characters: — 



It is somewhat larger; the apices of both fore- and hindwings are black, not 

 white. The oblique white patch on forewings is broader and has a .strong projection 

 at lower angle of cell ; the small white spot in the cell is wanting, as are also the blue
