PSYCHE. 



[June 1S93. 



with the costa of the primaries heavily lav'ed 

 with light pink and the margins of the sec- 

 ondaries slightly tinged with the same color- 

 Expanse, 30 mm. 



Argila, Walk. 



132. A. affinis, sp. nov. J. Closely related 

 to A. basalts, Walk., from which species it 

 differs in having the dark sub-basal band, 

 which separates the yellow area at the base of 

 the wing from the rest of the wing, incom- 

 plete, and the entire costal half of the wing 

 uniformly brown, the dark sub-basal band 

 being represented simply by a subquadrate 

 spot upon the inner margin near the base. 

 The marginal and sub-marginal markings 

 also differ from those of A. basalts, being 

 more distinct and darker towards the outer 

 angle. Expanse, 27 mm. 



133. A. basalts, Walk. ?. The female 

 differs from the male in the much lighter 

 color of the wings, and in having the prim- 

 aries very greatly produced and strongly 

 arcuate on the costa before the apex. The 

 abdomen also, in the gravid specimens 

 before me, is one-half longer than the poste- 

 rior margin of the secondaries. The expanse 

 of wings is, further, very much greater than 

 that of the male. Expanse, J , 27 mm.; $? , 

 38 mm. 



Terphothrix, gen. nov.* 



J. Palpi small, compressed, third joint 

 very minute. Antennae about one-third as 

 long as the costa of the primaries, heavily 

 pectinated the whole of their length, the pec- 

 tinations compressed laterally and the ex- 

 tremity of the culmen curved downwardly. 

 Legs moderately hairy, the last pair armed 

 with a double pair of spurs, one at the ex 

 tremity of the tibia, and the other pair about 

 the middle. The second pair of legs have the 

 tibiae enormously swollen at the extremity,

the enlargement being densely covered with 

 scales. This feature is especially noticeable 

 in the female. The upper part of the abdo- 

 men is adorned with long tufts of hair, which 

 are parted and spread out laterally in the 

 case of the first four immediately succeeding 

 the thorax. The two nearest the anal extrem- 

 ity are compressed and directed upwardly. 

 The peculiar arrangement of these bunches 

 of hair on the dorsal line of the abdomen 

 presents somewhat the appearance of the 

 tufts which are found on the backs of some 

 cochliopod larvae. The primaries are sub- 

 triangular with the costa slightly rounded 

 before the apex: the outer margin nearly 

 straight; the outer angle obtuse; and the 

 inner margin straight. The secondaries are 

 subpyriform. 



5 • The female is very like the male but 

 larger and with a much stouter body, and has 

 not, in any of the specimens before me, any 

 trace of the very peculiar tufts, which are 

 found on the back of the male. Type, 

 T. lanaria, Holland. 



It is worthy of remark that the peculiar 

 tufts are very liable to be abraded in dried 

 specimens, and it is possible that these tufts 

 maybe found also in the female, though four 

 very well preserved specimens do not reveal 

 any trace of them, except one in which two 

 minute tufts appear toward the anal angle. 



134. T. lanaria, sp. nov. $ . Front and 

 upper side of abdomen creamy-white. Ante- 

 rior wings creamy-white, with the middle 

 area clouded with warm brown. There are a 

 series of dark dots upon the costa, one be- 

 yond the end of the cell, and two before the 

 apex, the innermost of which is the smallest. 

 There is a narrow light sub-basal transverse 

 line and a transverse submarginal line pro- 

 duced on the second median nervule toward 

 the margin, both of which lines are pale, 

 shaded on the side toward the base with 

 darker brown markings. At the point where 

 the submarginal line is produced outwardly, 

 there are a series of blackish spots defined in-
