PiTHAURiOPSis, gen. nov. 



Male. — Closely allied to Fithauria, Moore, but di^ering, in the 

 forewing, in tlie distance between the origins of the second and third 

 median nervnles being greater, instead of less, than that between those 

 of the first and second, in the submedian nervure being strongly sinuated 

 w^here it comes into relation with, and the internal area expanded 

 opposite to, a prominent bilobed discal glandular organ, extending from 

 the root of the first median nervule for a short distance into the inter- 

 nal area, and consisting of two unequal slight depressions of the wing- 

 membrane, separated from one another by the interno-median fold, and 

 converted by over-arching stiff modified scales into pouches, which are 

 filled with a soft and fine and adhesive brown woolly substance : and, 

 in the hindwing, in the^first subcostal nervule being at its origin strongly 

 arched towards the costal, and the base of the second slightly bowed 

 into the cell and more acutely angled at its junction with the disco ^ 

 cellular nervule, in the subcostal, in fact, with its branches having the 

 shape rather of a tuning-fork than of the letter Y ; discoidal nervule 

 absent, and only one disco-cellular consequently present, as in Plthauria. 



The male genital somites and appendages, though at first sight 

 appearing very different, yet when carefully examined are seen to be built 

 on the same plan and to differ in characters of specific value only from 

 those of Fithauria.

233. PiTHAURiOPSis AiTCHisoNi, n. sp., PI. XY, Fig. 4, cT- 



^ . Upperside, both wings rich bronzy-brown. Forewing with a 

 basal streak on the costa, another in the cell, one in the submedian, and 

 a fourth, the longest of all, filling the interno-median interspace, all 

 composed of long yellowish-olivaceous hair-like scales ; two oblong spots 

 placed obliquely at the end of the cell, the anterior one the farther from the 

 base of the wing ; two subcostal spots, the anterior one a mere dot ; an oval 

 or heart-shaped spot in the second median interspace; and a romboidal one 

 in the space behind ; all semi-transparent ochreous. Hindwing with all 

 but the costal and outer margins clothed with very long yellowish oli- 

 vaceous hairs. Underside, /oreww^ blackish, with the costal and apical half 

 of the wing yellowish-brown. The spots as above save that those in the cell 

 are conjoined into an ill-shaped figure of 8, and that there is a sabmarginal 

 series of yellowish dots from the first median nervule to the costa. Hind- 

 iving with a minute yellow spot in the subcostal interspace, two larger 

 ones (the anterior the larger) in the median interspaces, a submarginal 

 series of small obscure yellowish spots, the two of which in the submedian 

 interspace are large and prominent, and a3^ellow streak on the abdominal
