 Hub. — Lithosia Fab. — Palparia Haw. — Tinea Hub., Fab. 

 Antenna inserted on the crown of the head, near the eyes, 

 rather short, setaceous, scaly above, pubescent beneath, each 

 joint producing longish hairs at the apex (1), shorter and simple 

 in the female. 



MaxillcE very much shorter than the labial palpi, slightly spiral 

 (3). Palpi as long, porrected obliquely, densely clothed with 

 scales (7 a), 4-jointed (3 a), basal joint obovate, 2nd globose, 

 3rd stouter and obovate, 4th twice as large, stout and oval. 

 Labial palpi very scaly, as long as the head and thorax, por- 

 rected horizontally like a beak, the apex slightly drooping (4). 

 triarticulate, basal joint short, 2nd very long, slightly fusi£orm, 

 slenderest at the base, 3rd slender short and elliptical {a) . 

 Head small, transverse-ovate: eyes large, globose (7, the profile). 

 Thorax small and oval. Abdomen long and slender with a small 

 tuft at the apex in the male ; very much thickened towards the apex 

 in the female, and either rounded or pointed, with a dense bundle of 

 hairs. Wings generally broader in the males and truncated ob- 

 liquely ; narrow, lanceolate and slightly falcated in the females : 

 inferior ample and folded, most ovate and pointed in the female : 

 cilia moderate. Legs slender, hinder very long : coxse, anterior 

 long : thighs tolerably equal : tibiae, anterior very short, with n 

 short internal spine, intej-mediate with a pair of spurs at the apex : 

 hinder very long, spurred at the apex, with a longer but unequal pair 

 also at the middle : tarsi very long and 5-joinied, basal joint very 

 long, terminal the shortest : claws very minute (8 f, hind leg).

The form of the palpi will distinguish this group from 

 Harpypterix, pi. 535, to which it is closely allied. The larvae 

 live in the stems of reeds and grasses, feeding upon the pith ; 

 and a species discovered by the late Mr. L. Guilding, which 

 he named Diatrea Saccharic is injurious to the Sugar-cane.
