LoBOGO'iA AMBUSTA, sp. n. (Plate XXXI. fig. 21.) 



J . Fore wings pale yellowish ochreous, with a very few scattered 

 fuscous strigae; 2 transverse, straight, oHve-brown lines, at 5 

 and I respectively, each starting from a darker costal blotch ; 

 costa itself finely speckled with black ; subterminal line in- 

 dicated by a small blackish costal spot, another on the inner 

 margin, and a third opposite the cell ; an oblong brownish blotch 

 almost touching the 2nd line in the middle, just beyond it ; 

 fringes more reddish, edged with black from apex to elbow, and 

 with 2 black spots below it. Hind wings like fore wings, but with 

 a single dark line just in the centre, and the fringes less touched 

 with black. Head, thorax, and abdomen ochreous ; antennae the 

 same, but much dusted with darker. Underside fulvous-ochreous, 

 much irrorated with transverse grey strigse, which are massed into 

 a blotch towards the base of the fore wings ; both wings with 

 distinct dark cell-spot, and central broad dark line ; inner margin 

 of fore wings clear ochreous, quite without markings. 



Expanse of wings 30 millim.

Mtosto3Ia, gen. nov. 



Fore wings with costa nearly straight, slightly curved only at 

 base and before apex ; apex produced, blunt ; hind margin 

 subfalcate below apex, with an elbow in the middle ; the anal 

 angle rather square ; hind wings rather narrow, pear-shaped ; 

 antennae $ simple, S faintly pubescent ; forehead rounded, 

 smooth ; palpi very short indeed, hardly perceptible ; tongue 

 weak. Neuration : — Fore wing : 1st median uen-ule at | ; 2nd and 

 3rd from the end of cell ; lower radial from the centre of the 

 transverse vein ; upper from the upper angle of cell ; 1st sub- 

 costal free ; 2nd and 3rd out of 4th shortly before apex, 5th 

 out of 4th at ^ from cell. Hind wings, $ : costal and subcostal 

 nervures strongly convex towards each other, approaching, but 

 not touching, about middle of cell ; 1st subcostal nervule rising 

 just before end of cell ; discocellular bluntly angulated, radial 

 from the angulation ; 1st median nervule at |, 2nd and 3rd from 

 a point at lower end of cell. 



Hind wings, d ■ with the costal and subcostal running more or 

 less parallel to middle of cell ; subcostal nervules from end 

 of cell ; discocellular angulated ; the lower end of cell produced 

 and rounded; 1st median nervule at |, 2nd and 3rd near each 

 other from the rounded extremity of cell ; radial at the same dis- 

 tance just beyond the 3rd. 



Type, M. straminea. 



This difference in the neuration in the two sexes is repeated 

 in the next genus, where the abnormality of neuration in the S 

 is still more noticeable. In Myostoma the wings are longer and 

 narrower in proportion in the <S than in the 5 • I have described
