Harrisina australis. (^. Similar to 11. Americana, bui larger. Head blacli. 

 Antenna; black, wiih a melallic blue tinge. Abdrimen and legs black. Prothorax 

 orange, the color extending to the base of the pata;^ia, and underside of the head and 

 breast. Wings shaped as in americana, but more opaque, blacker and with a more 

 positive blackish-green reflection. 



E.xpanse of wings 1.15; length of botly 0.50 Indies. Hub. Florida, 

 Hy. Edwards. 



Out of the four American species this is the only one which has the 

 underside of the head yellow, and this character will instantly separate 

 it. In size, the range o'i americana is from 0.75 to i.oo inch, with an 

 average of about o. 90 inch, so there is a notable difference in size as well 

 as color. 



Harrisina metallica. Similar to americana but much larger. Entire insect 

 above and below, lustrous blueish-green, with the wings a shade yellower than the ab- 

 domen. Prothorax orange, the color not extending to the underside of the head. 

 The wings have the apices much rriore produced than in americana or australis. 



E.xpanse of wings 1.60 inches; length of body 0.50 inch. Hab. New 

 Mexico, Prof Snow. 



Very distinct from any of the other American forms. The types 

 were received from Prof Snow under the name 0^ H. americana, and it 

 may probably be in other collections under that label. 



Nola hyemalis. 9c:f- Head and palpi whitish, palpi darker beneath. Ab- 

 domen pale. Body beneath, and legs darker. Primaries very pale gray, resulting 

 from a sprinkling of minute brown dots on a white ground, somewhat darker towards 

 the outer margin and apex. Costa with a dark brown streak at the base, and' wings 

 crossed with three indistinct lines made up of dots. Basal line most distinct, at one 

 third from the base, oblique, straight, parallel with the outer margin, with a distinct 

 brown dot near the costa, made up of tufted scales. The second line is slightly beyond 

 the middle, parallel with outer margin for half its length, then rounding rapidly to 

 the costa. The third line originates near the anal angle, is parallel with the second, 

 and leaves the terminal space broadest on the costa. Each of these lines is followed 

 outwardly by a very narrow white shade, and the lip of the wing is faintly striped, 

 owing to the varying depth of color of the veins and interspaces. Fringes long, dark- 

 er than the wing, and distinctly separated therefrom by a very narrow pale line. 



Secondaries very pale, shaded with darker tints at the apex. Fringes very long, 

 concolorous. Beneath, immaculaie, primaries darkest. 



Expanse of wings o 80 inch. Hab. Crystal Springs, San Mateo 

 County, (Hy. Edwards); Alameda County, Calif (Behr). 



Does not appear to be uncommon in March and April on fences 

 and at light. 



Cisthene plumbea. Head and thorax lead color. Abdomen bright red above, 

 dusky beneath. Primaries lustrous drab or lead color, with a somewhat triangular 

 whitish spot on the inner margin, two thirds from the base. Secondaries clear pink, 

 with a broad costal lead colored margin, which is continued along the outer margin, 

 decreasing in width to the anal angle. Beneath as above, but somewhat j^aler.
