two species of Stibadmni the front is much as in Basilodes ; in 

 Aureoluni Hy. Edw., an exquisite species, the excavation is a very 

 little deeper and smaller than in Spiiniosum, in both partly con- 

 cealed. In Stiria the patagia are prominently deflected. I find 

 the labial palpi much longer in Basilodes, as compared with Stiba- 

 diiim. What Mr. Smith says as to the relationship of these genera 

 is partly correct ; I have overlooked the resemblance which Basilo- 

 des bears to them, but I should not unite them ; each has some dis- 

 tinguishing points and Stiria, especially, somewhat strongly de- 

 parts. Basilodes, Stibadiiun, Stiria, Plagioniimicus and Polenta 

 belong to a group, oscillating between Calpe and HcliotJiis, which 

 I have called ^itiriinoi in the New Check List. 



But, contrary to Mr. Morrison and Mr. Smith, I demonstrate 

 the presence of a tibial claw in Polenta Tepperi, from an Arizonian 

 specimen in coll. B. Neumoegen, Esq. The difference between 

 Polenta and Plagiorni>niciis is thus confined to a modification of 

 clypeal structure. It is not more distinct from Basilodes than the 

 other genera. Mr. Smith accuses me of '' resurrecting " Trigono- 

 phora; if he will look in Lederer, he will see that I took the 

 genus from Lederer, and that I have followed this most distin- 

 guished authority in using Hubner's genus. In two very import- 

 ant statements I find Mr. Smith thus quite wrong. I shall allude 

 to others. Mr. Morrison's statement that Polenta had unarmed 

 tibise always seemed to me doubtful from the great resemblance 

 between Polenta Tepperi and Plagioniimicus Pityochromus {Media 

 Morr.) in shape and ornamentation. The genera are not suf- 

 ficiently distinct. Consult Bull. B. S. N. S. Vol. 3, pp. 75-76, 

 1875. 



Plagiomimicus Expallidus. n. S. 



Wings pale olive ochrey with the s. t. line white-edged on costal 

 region, margining outwardly the costal, dark triangular shade. 

 T. p. line oblique, even, edged with white inferiorly. Median 

 space somewhat yellowish and darker inferiorly. Stigmata lost in 

 the pale shading of the discal cell, which shows a dark dot in the 

 middle. Hind wings whitish. Smallerand differently colored, of 

 a faded hue compared with the dark Pityochromus. Montana, 

 Coll. B. Neumoegen, Esq. Expanse 26 mil. 



Genus Capis, Grote. 



A Deltoid genus with broader and squarer wings compared 

 with Sisyrhypena. Antennae ( $ ) simple, ciliate. Vestiture flat- 

 tened, hairy, very silky. Eyes naked, tibiae unarmed as usual in 

 this group. Ocelli ; eyes unlashed. Body slender, untufted. 

 Abdomen not exceeding secondaries. Labial palpi loosely held, 

 exceeding the front, third article short, second with longer and 

 thicker scales. Tongue rather weak. 



Capis Curvata, Grote. 



A rather small species, deep brown on primaries to the 

 curved s. t. line running from apices downward somewhat obliquely
