8 Mr. A. G. Butler on Heteroceroiis Lepidoptera 



fringe rufous-brown ; thorax smoky brown, reddish 

 beneath the surface- scales ; a few greyish scales towards 

 the front ; head whitish ; antennae blackish ; abdomen 

 foxy red ; wings below foxy red, shading into piceous 

 towards the apices (this colom- extending over the apical 

 half of the primaries) ; body below sandy brownish, 

 slightly fuliginous in front. Expanse of wings, 1 inch 

 7 lines. 



PSYCHIDiE. 



ACOUSMATICUS, n. g. 



Aspect of Psyche, but the antennae formed as in 

 Pentlwplicra, although considerably larger and of about 

 three-fourths the length of the primaries, broadly 

 pectinated on both sides, the pectinations deflexed ; a 

 woolly projecting tuft between the eyes ; palpi long, 

 slender, angulated, and deflexed; wings semitransparent, 

 the cells (especially that of the secondaries) short ; veins 

 radiating ; primaries elongate-triangular, the angles 

 rounded off; cell of primaries enclosing two smaller 

 cells formed by recurrent veins from the disco-cellulars, 

 which are united behind ; submedian not looped, but 

 dividing at basal third into two closely-approximated 

 branches which run to external angle ; secondaries 

 rather small, oval, the costal border convex to beyond 

 the middle and thence slightly concave to apex ; no true 

 costal vein, its place being occupied by the subcostal 

 which terminates in three parallel approximated 

 branches ; disco-cellulars acutely inangled with re- 

 current veins nearly as in the primaries ; median vein 

 four-branched ; legs long and rather slender. 



13. Acousmaticus magnicornis, n. s. 



Fuliginous-brown, thorax and wing- veins darker ; 

 primaries and dorsal surface of abdomen darker than 

 the secondaries and the sides of the abdomen ; antennae 

 black ; wings below greyish, sericeous ; primaries with 

 a pale spot at the extremity of the discoidal cell ; body 

 below whity-brown, the tarsi slcnderl}^ banded with grej^; 

 the pectus clothed with fuliginous hairs. Expanse of 

 wings, 10 lines. 



This very remarkable little species must certainly 

 belong to the PsijcJiicUe, with which it agrees in the 

 general plan of its neuration.
