much like that of Semiothisa, the costal region being narrow ; the subcostal 

 veins are longer and more parallel to the costa than in Semiotfma ; the outer 

 end of the subcostal areole is open, being closed in Semiothisa and Dias- 

 tictis. In this respect it resembles Eubolia, in which it is also open. The 

 costal vein joins the subcostal areole opposite the anterior discal venule. 

 Abdomen long and slender, rather square at the tip. Hind tibiae swollen ; 

 tarsi a little over half as long as the tibia-. The markings of this genus are 

 usually very characteristic, the front wings being crossed by three well- 

 marked lines, the outer and inner often bright ochreous, the yellowish por- 

 tion sometimes suddenly disappearing near the costa; the yellowish lines are 

 sometimes replaced by distinct, black, straight or sinuous lines. There is 

 usually a single line on the hind wings, either entire or obsolete before reach- 

 ing the middle of the wing. Four indistinct discal dots usually present. 

 The females scarcely differ from the males in the shape of the wings and 

 markings. 



This genus may be known by the usually slightly subfalcate fore wings, 

 the straight costa, bent outer edge, square hind wings, with the apex well 

 rounded, by the long slender abdomen, and the swollen hind tibiae Eubolia, 

 which is represented in this country by an undescribed species, differs from it 

 in the fore wings being much more rounded at the apex, the costa straighter, 

 being slightly curved in, and by the fuller outer edge, whilethe costal edge of 

 the hind wings is shorter. {Eubolia murinaria is the only named species I 

 have for comparison.) Dlastictls is remarkably near Phasiane, and at first I 

 was inclined to regard the differences as not generic; it differs from Phasiane 

 simply in the longer pectinations of the antenna? and the more rectangular 

 apex of the fore wings and the more decided bend in the outer edge of the 

 wing, but especially in the much longer, slenderer hind legs, the tibiae not 

 being swollen. The venation differs more decidedly, the subcostal areole 

 being wider, the whole costal region in fact wider, and the cell being closed. 



The species van in the antenna? and shape of the fore wings; in P. 

 atrofasciata and P. subminiata, (he costa and outer edge being very straight, 

 especially the outer edge. 



P. atrofasciata and subminiata in their venation are almost identical with 

 the lower division of Semiothisa, the subcostal areole being open externally, 

 and, except in the style of markings, it seems impossible to separate the two 

 genera ; and the separation as regards G. ocellinata, californiata, and P. atro-
