330 FIRST ANNUAL REPORT OF THE STATE ENTOMOLOGIST. 



(Canad. Entomol., x, p. 169). It is the presence of a long and thick tuft of hairs 

 on the posterior tibiae. This is not found in N. Brizo Boisd.-Lec. — a species so 

 closely allied to N. Icelus that some writers have questioned their specific dif- 

 ference. It has been observed in but one other species of Nisoniades, viz., N. 

 Persius Scudd. It also characterizes the Hesperidean genus Daimia of Murray, 

 of which the European D. Tethys Men. is the type and sole species, and Scelo- 

 thrix of Ramb. — united with Pyrgus H. by Dr. Speyer in his last Revision of 

 the European Hesperid^ (1878), as Group II, having maculatus Brem, as the 

 type of the group. This tuft or hair-pencil differs in the several species. In N. 

 Iceltis it is produced from the femoral joint of the tibia, and is widely spread 

 apart in the examples before me. la length it exceeds the tibia by nearly one- 

 half. Like the costal-fold, it is probably confined to the $ sex. 



A revision of the proof of this paper has enabled me to add the following : 

 Since the above was written, an examination of the Nisoniades in my collection 

 has shown the presence of the tibial hair-pencil also in the males of N. funeralis 

 Boisd., N. Ncsvius Lintn., and N. LuciJius Lintn. I cannot detect it in any 

 other than the above-mentioned five species. In the genus Pyrgus, I find it in 

 P. centaurecB Ramb., P. scriptura Boisd., P. Xanthus Edw., P. Petreius Edw., 

 and P. ericetorum Boisd. It is not present in P. tessellata Scudd. Of P. Oceanus 

 Edw., P. Ricara Edw., P. Philetas Edw., and P. cm2ntalis* Boisd., I possess 

 no examples for examination. It exists also in Aclilyodes Thraso Hiibn. 



Nisoniades Somncs n. sp. 



Belongs to the N. Icelus and N. Brizo group ; size of the former — its wings 

 somewhat narrower and more extended apically, 



Male, dark brown in color, approaching N. Persius. Primaries, without the 

 ante-apical white spot above, and the large patch of bluish-white scales resting 

 on the discal cross-vein of N. Icelus. The black transverse bands are of the posi- 

 tion and character of those of N. Icelus, but are almost lost in the ground color. 

 Secondaries, nearly as dark as the primaries, showing indistinctly the two rows 

 of pale brown spots. 



Beneath, wings bronze by reflection. The primaries have a short costo-apical 

 white streak in cell 8, and a minute white dot in cell 9 (iV. Icelus has usually a 

 subquadrangular white spot in cells 6, 7 and 8 each, and occasionally the spots 

 form a continuous line nearly across the wing, from 2 to 8 inclusive) ; an in- 

 tranervular series of pale streaks, and on the secondaries, the two rows of yel- 

 low-brown spots are distinct. 



Female, paler brown than the male. The two transverse bands of primaries 

 are quite distinct, and between them, on the discal cross-vein, is a conspicuous 

 patch of whitish scales ; no white ante-apical spots; upon the margin, a row of 

 rounded brown spots, separated from the contiguous band, by whitish scales. 

 The bands are broader than in iV. Icelus, and are almost drawn together on vein 

 2 ; the connected series of spots composing each, are shaped much as in If. Icelus, 

 are heavily bordered with black, and bear bluish scales. Secondaries, with a 

 eeminate discal mark, a submarginal row of yellowish spots much bent inwardly 

 opposite the cell, and a marginal row of small, linear, whitish spots. 



Beneath, wings with a strong bronze reflection. The secondaries have the 

 two rows of spots of the upper surface repeated ; the primaries have a marginal
