1. Catalexis tapinota, sp. n. (Tab. I. fig. 18.) 
Antennae silvery whitish, shaded with pale fawn-brown towards the base. Palpi whitish ochreous, whiter 
on their inner sides, unspotted. Head shining whitish ochreous, with some iridescent steely bluish 
scales above. Thorax steely grey, the tegulae ochreous. Forewings fawn-brownish, shaded with dark 
fuscous (almost black), a very narrow streak of this along the base of the costa to one-fifth, an elongate 
patch from the base of the dorsum below the fold, extending nearly to the dorsal cilia; above it a 
shorter cloud-like patch on the cell commencing before and extending a little beyond the middle of the 
wing; the whole apical fourth is overlaid with dark fuscous, the anterior margin of this dark patch 
lying almost parallel to the termen, but somewhat attenuated to the apex, a few fawn-brown scales in 
this patch opposite to the termen ; cilia pale brownish ochreous, shaded with fuscous about the tornus. 
Exp. al. 12mm. Hindwings dark fuscous, with some brownish ochreous scales intermixed along the 
costa and dorsum; cilia dark fuscous. Abdomen fawn-brownish, shaded with fuscous. Legs whitish 
ochreous, unspotted; anterior and median legs somewhat shaded above with fuscous.

J. H. Durrant, del. 
6. Logists achroea Wlsm. 9. 
Antennae (?) %, simple, slightly dentate towards apex ; basal joint without pecten. Labial Palpi as long 
as the head and thorax, projecting; median joint straight, with long upstanding scales above, these 
higher towards the base, but combining with others at the apex, from the lower side, to form a 
projection beyond the base of the smooth, slender, upstanding terminal joint. Mawillary Palpi very 
short. Haustellum scaled. Head and Thorax smooth, with a metathoracic tuft on either side 
posteriorly. orewings slightly convex on their basal half, straightened beyond, the apex moderately 
depressed, termen oblique, not sinuate: neuration 12 veins; 9 out of stalk of 7 and 8, 7 to costa ; 
2-6 separate, 2 remote from 3. Hindwings somewLat narrowed towards base, widening outwardly, 
trepezoidal ; costa straight, apex obtuse, termen subsinuate, thence rounded, dorsum receding ; with a 
strong tuft of hairs above at the base of vein 1*; cilia very long, almost as long as width ‘of wing 
towards base: newration 8 veins; 3 and 4 remote; 5 straight, approximate to 6; 6 aud 7 separate, 
but approximating; radius connected to subcosta by cross-vein. Abdomen long, smooth. Legs (hind 
legs missing, probably long). 
The genera Logisis and Catalewis have a peculiar form, and are perhaps charac- 
teristic of tropical America. Their true affinities in the absence of described con
