-As in stra\::;iila in markings. I'he thoracic parts arc a little 

 paler, i-'orc wings pale ocher yellow except along costa, the 

 costal half of median space, and the narrow terminal space, where 

 they are gray with tiie tint of sfroi^u/a, but paler. All the brown 

 markings are as in s/r(ii;///(7 ami the same color, 'ihe difference lies 

 in the jiale color of the region about internal margin, base, andT 

 sub-terminal line, which in strai:;ii/a is only partly ochraceous being 

 usually largely deep brown. Here the brown color is almost 

 entirely confined to the marks, the ground color being pale ochra- 

 ceous, and encroaching on the gray parts of the wing.

A NEW LITHOSID GENUS. 



\\\ r.. Xkumof.c.kx, Nkw York. 



Bruceia, nov. gen. Head small, eyes large. Taipi short ami thin. Thoia.x 

 moderate. I'.ody long and slender, with slight anal tuft e.xtending somewhat be- 

 yond wing. Antenniv j setose, nearly sub-serrate, O simple. Primaries well 

 drawn out, about 2'.j times as long as broad, slightly rounded at apices. Angle 

 produced ; inner margin somewhat cor.cave at centre ; I2 veins. \'ein i free from 

 base, slightly sinuate ; vein 2 arises from beyond centre of median ; vein 3 from 

 lower angle of cell ; 4 and 5 nearly contiguous at origin ; cell closed ; discal vein 

 angulate inwards ; vein 6 arises froiu cross-vein, a little below apex of cell ; veins, 

 7, 8 and 9 from a stalk at ape.\ ; veins 10 and 11 arise independently from sub- 

 costal, II beyond centre of cell, lo being interm diate ; vein 12 free from base. 



Secondaries nearly as bioad as long, well rounded at anal angle. Two inter- 

 nal veins ; veins 2, 3, 4 and 3 iiientical in position with those of primaries ; 6 and 

 7 emanating from a stalk at upper angle of cell : vein 8 springs from a little before 

 centie of subcostal. Legs long and slender ; two pair of tibial spurs.
