PSYCHE. 



535 



The under side of the body and the legs are 

 mouse color. The primaries and the secon- 

 daries on the upper side are mouse color, 

 shading slightly on the inner margin into 

 brownish. The inner margin from the base 

 to the middle below vein one is dark, black- 

 ish-brown. The wings are crossed by a num- 

 ber of brownish transverse striae and marked 

 on the outer third by a straight transverse 

 brown line running from the costa two-thirds 

 of the distance from the base to the outer 

 angle, where it unites with a similarly colored 

 curved submarginal brown line. The secon- 

 daries are marked on their inner two-thirds by 

 numerous, narrow, transverse brown striae. 

 On the under side, both wings are paler than 

 on the upper side and the markings of the 

 upper surface faintly reappear. Expanse, 50 

 mm. 



Metarbela, gen. nov. 



Allied to Arbela, Moore, but differing in 

 the following particulars : The antennae are 

 relatively shorter than in the genus Arbela; 

 the primaries have a bar between veins nine 

 and ten a little beyond the origin of vein 

 seven, which together with vein eight are 

 emitted from vein nine. The existence of 

 this bar results in the formation of a secon- 

 dary cell beyond the true cell. In the secon. 

 daries, vein one has two branches, whereas in 

 Arbela there are three; and veins six and 

 seven are stalked, whereas in Arbela 

 they spring directly from the cell. Type 

 Metarbela stivafer, Holland. 



183. M. stivafer* sp. nov. $. The 

 palpi brown; front very light brown ; collar 

 and patagia darker brown; upper side of 

 thorax and abdomen clothed with golden . 

 ochraceous hairs ; the lower side of thorax 

 and abdomen covered with long silky pale 

 ochraceous scales. The primaries on the 

 upper side are pale ochraceous with the outer 

 margin fading into pale cinereous. The 

 fringes are a trifle darker than the marginal 

 portion of the wing. The body of the wing 

 below the cell and beyond it toward the 

 outer margin is clouded with brownish 

 irregular markings. On the lower margin 

 a well defined silvery line runs from the base 

 to the outer angle. This line is curved 

 strongly beyond the base forming almost a 

 semi-circle from the base to the origin of the 

 first median nervule, and then runs along this 

 nervule as a straight line to the outer angle. 

 Midway between the outer angle and the 

 origin of the median nervule a white silvery 

 spot appears and is confluent with the silvery 

 line on its lower side. The lower margin of 

 this silvery line is sharply defined by dark 

 brown. The secondaries are uniformly very 

 pale fuscous. On the underside, both wings 

 are pale fuscous. Expanse, 25 to 30 mm. 

 I have a series of sixteen males of this 

 species, but no females. I give it its specific 

 name from a fancied resemblance to the out- 

 line of a plough-tail which the silvery marks 

 upon the primaries present when viewed 

 from in front.
