 Californian; in another, the ground-color of the wings is Scotch-snn If colored.

A peculiar, green female, received I'nun ('alitbrnia through .Mr. Jiehrens, 

 differed so much from the others that it was descrilx'd as distinct under the 

 name oi Hydrioinena viridnta. 1 appi'ud a description of this interesting 

 variation. It was in a perfect state of preservation, and closely allied structu- 

 rally and as regards size to the ordinary lln-ni, tlie palpi lieing long, and ex- 

 tended as far in front of the head as the latter is long; the outer edge much 

 as usual, Ix'ing less ol)lique than in some other species : the third subcostal 

 interspace is narrower than in the other specimens. Head, thorax, and 

 fore wings deep sea-green, mixed with dull, dark, smoky-ash, and some 

 yellowish-green and a few black scales. Palpi with no gretm scales, l)ut 

 black and pale asli, being darker below than above. Antenna' finely ringed 

 with white and blackish. Fore wings of a sea-green groniul-color, with 

 numerous fine, transverse strigte, crossed i»y live clear, smoky-ashen, sinuous 

 bands, finely edged with lilack ; the basal very short and narrow, close to the 

 base of the wing; the second lin(> is narrow, ends liiriiu>r from the base of 

 the wing on inner than on costal edge, and is angulaled outward conspicu- 

 ously on median vein. The third band is close to, and jtarallel with, the sec- 

 ond, and twice as wide ; it is bent outwaril on the median and submedian 

 veins. A fourth, faint, narrow band, close to third. The fifth, or submarginal 

 line, is twice as Ijroad as third, and very remote from the latter (which is 

 within the middle of the wing) ; it is nearly straight on the inner edge, 

 though curved outward just below the costa, while the outer edge is deeply
