328 GROTE AND ROBINSON. 



The present species sustains a similar relation to A. Jipsaei, with 

 that borne by A. langtonii to A. octomaeulata. It is. however, larger 

 than any of the allied species. From A. dipsaci,it differ? prominently 

 by the single reduced spot of the secondaries. The condition of the 

 body parts in our material prevents any nice discriminations between 

 the two species, so fiir as the corporal coloration is concerned.

7. Alypia lorquinii, n. sp. (Plate 6, fig. 39, %.) 



■^ . — Allied to the Canadian A. macculloehii, and to A. ridinsrsii 

 from Colorado Territory. Black. Head black ; eyes prominently mar- 

 gined behind with sulphur yellow ; labial palpi roughly scaled, black, 

 prominently exceeding the front ; maxillae blackish ; antenn^ie black, 

 terminally enlarged, neatly and closely sub-annulate with .white along 

 their basal portion. Thorax, black ; tegulae sulphur yellow, fringed 

 with black hairs. Abdomen, black, with two approximate, dorsal, sul- 

 phur yellow dots at base. Legs, mostly closely scaled, blackish; an- 

 terior and middle tibiae fulvous; the middle femora are also somewhat 

 touched with fulvous inwardly. 



Win<:s black, somewhat lustrous. Anterior wings with the costa 

 swollen and slightly convex centrally, owing to the enlargement of 

 the interspace above sub-costal nervure. A^eius marked by lustrous 

 scales. At base, a large sulphur yellow patch, obliquely margined out- 

 wardly and straightly inferiorly, neatly divided by the black median 

 nervure into dissimilar portions. A rounded spot on the disc, and a 

 transverse, sulphur yellow, narrow elongate-oval spot beyond the disc, 

 neatly divided lour times by the black nervules. Secondaries with a 

 laroe whitish spot at base, the black median nervure separating a small 

 portion inferiorly. Beyond the discal cell, an elongate, narrow, whit- 

 ish spot, much as on primaries (but reversed, tapering inferiorly), and 

 divided three times by the black nervules. Fringes, on both wings, 

 black and lustrous. On both wings beneath, the ornamentation of the 

 upper surface is reproduced; the spots are very pale yellow ; on the 

 secondaries the extra discal spot has lost its inferior dot, is broader 

 and itrohinged above sub-costal nervure towards the base of the wing.

Compared with three % specimens of A. macculloehii, agreeing with 

 Kirby's figure, contained in the British Museum Collection, and so de- 

 termined in the B. M. Lists, the present species differs by the sub-ter-
