164 Lord Walsingbam's revision of the 



palpi pale brown. Fore wings pale brown, rounded at the apex ; 

 the costa slightly arched, pale brown, sparsely sprinkled with dots 

 of darker brown, especially along the costal margin; the extreme 

 base of the costa dark brown ; there is but a slight indication of 

 the usual discal spot ; apical vein not forked. Hind wings darker 

 than the fore wings, brownish fuscous; fringes inclining to greyish; 

 on the under side the hind wings are paler than the fore wings. 

 Abdomen greyish fuscous. The peculiarity of this species consists 

 in the anal appendages: the lateral cbispers are narrow at the base, 

 dilated into a wide triangle posteriorly, having a distinct pro- 

 jecting point at their lower apex ; the uncus is much bent over, 

 consisting of two very long slender converging points, thickened 

 below their middle with irregular knobs on the outer side. Exp. 

 al. $ , 20 mm. ; ? ? , 23* mm. 



One male and one female in Zeller's cabinet, collected 

 by Baron von Nolcken at Bogota. The form of the 

 nncus distinguishes this species from all its known 

 congeners. 



The female, if I am right in believing it to belong to 

 this species, has the palpi projecting forward about 

 1^- mm., not recurved. The spot at the end of the cell 

 more apparent than in the male. 



Anaphora tenuis, n. s. (PI. VIII. , fig. 18). 



Palpi recurved, reaching as far as the posterior edge of the 

 thorax ; fuscous at the sides, tending to ochreous or brownish 

 ochreous beneath (the under side being turned upwards their paler 

 colour renders them conspicuous). Antennce brownish ochreous, 

 serrated, the end of each article fringed with slender hairs. Head 

 and thorax purplish fuscous. Fore wings purplish fuscous, with 

 scarcely any markings ; such as there are in some specimens 

 consist of a dark spot on the disc, and a larger one on the fold 

 preceded by a darkish patch ; in one variety collected by Boll in 

 Texas, which I believe to belong to this species, the dark spot on 

 the fold assumes the form of a rather conspicuous triangular 

 blotch. Hind icings brown, with scarcely paler fringes. Abdomen 

 the same ; much more slender than in the species allied to plumi- 

 frontclla ; lateral claspers somewhat attenuate near the base, 

 elongate-ovate beyond, evenly rounded at the ends ; the uncus is 

 curved over, not angulated, the two points very short, slightly 

 diverging, with a pair of small supplementary lateral processes at 

 its base. Exp. al. 24 mm.
