596 Pieter C. T. Snellen on d 



orm a new one. Labial palpi porrected, rostriform, pointed; 

 their base snow-white, the remainder bright ochreous brown as the 

 distinct maxillary palpi and the white-edged front. Antennae 

 setaceous, almost bare, their length three-fom'ths of the costa of 

 fore wings. Shape of wings as in Botys, especially hyalinalis, 

 flavalis ; the fore wings dark fuscous brown, with a violaceous 

 tinge, and glossy ; they are margined with ochreous yellow, 

 narrowly along the costa, broader and suffused round the apex, 

 and again narrow along hind margin ; fringes also yellow ; costa 

 of fore wings marked at two -thirds with a brown spot, indicating 

 the origin of the second line, which is slender, blackish grey, and 

 continued on hind wings, where it is nearly straight till vein 5, and 

 subsequently runs closely to hind margin ; a blackish first trans- 

 verse line on fore wings and a discal dot are indistinct. Hind 

 wings greyer, also with a narrow yellow hind margin, the marginal 

 line brown, with minute spots. Under side of wings paler and greyer, 

 marked as on upper side, the yellow border also paler, narrower, 

 also continued along the costa of hind wings. Legs and under side 

 of body pale yellow ; upper side of abdomen fuscous ; anal tuft 

 long, pale. The fore wings have a very short discoidal cell, and a 

 circular depression beyond it on the bases of veins 6 and 7, which 

 is also visible on the upper side ; besides, the crest which retains 

 the frenulum on the under side near the base of the wings is 

 unusually strongly developed.

115. Crocidophora? Jiavicilialis, now. sipec. (PL XX., 

 figs. 5, 5 a). 



A male of 23 mm. expanse. 



This species very much resembles the preceding, but the most 

 striking difference is indicated by the name ; besides, and this, as 

 a structural character, is more important, it has no groove or 

 depression on the base of the veins 6 and 7 of fore wings, and their 

 discoidal cell is of normal length ; at the base of the discoidal cell 

 a small groove is visible, and the crest at the under side is as large 

 as in flavicvnctalis. Palpi porrected, rostriform, pointed, fully 

 twice as long as the head, bicolorous, pure white and bright 

 ochreous brown. Antennae fully two-thirds of fore wings, setaceous, 

 fuscous. Head, upper side of thorax, and fore wings bright 

 ochreous brown, rather dull, uniform, a little violaceous on outer 

 third ; markings dark grey, very faint, consisting in two undulated 

 lines and a reniform discal spot ; the second line is retracted behind 

 this spot ; extremity of hind margin bright ochreous yellow, the
