visible at all. The form and position of this streak are almost exactly 

 as in Haicorthana but it is more slender and pointed. In impigritella 

 the fore wings are said to be dark bronzy brown slightly touched with 

 golden brown between the costal streaks ; in this specimen the basal 

 part of the wing and the thorax and head are dull leaden brown, with 

 faint bronzy reflections in some lights, and passing about the middle 

 mto golden brown which covers the apical half of the wing though in 

 some lights portions of it appear dark brown. There are five costal 

 streaks placed as in imjngritella and equitella 2, 1, 2 and (as in im- 

 ingritella) all these streaks are decidedly dark margined internally ; 

 but these dark margins do not extend across the wing as in impigritella, 

 nor do the dark margins of the first and second streaks meet; the ex- 

 treme costal margin is dark brown from the base to the tip, except where 

 it is in tempted by the costal streaks. Dr. Clemens says that the ' costal 

 and dorsal streaks in imjngritella are silvery white, and that the violet- 

 silvery' spots are absent. In this insect the costal streaks are all white 

 but are tipped Avith violaceous metallic scales, and the second and 

 third are especially so; the first is oblique decidedly, the second less 

 so, and the others are perpendicular to the margin ; opposite the points 

 of the first and second costal streaks is a dorsal white streak placed as 

 in impigritella, but ending in a violet metallic spot ; the second costal 

 streak— metallic violet, as in equitella— yioints towards but does not quite 

 attain a violet metallic spot within the dorsal margin, which is not 

 mentioned in the account of impigritella, but which in Haworthana is 

 represented by the second of the metallic spots; and in equitella 

 by the first one that is the longitudinal or oblique dash, (not 

 by the spots which in those species the second costal streak nearly or 

 quite touches,) it is immediately opposite the third costal streak ; with 

 careful manipulation there may be observed a minute violet metallic 

 point opposite to the fourth costal streak and just within the dorsal 

 margin ; the last dorsal and last costal streaks are opposite and both 

 are white tipped with violet metallic scales and are slightly curved and 

 almost meet so as to form a fascia concave towards the apex. The 

 apical patch is velvety dark brown, the cilia of the dorsal margin and 

 apex are greyish silvery with a wide fuscus band covering their base. 

 Unfortunately though the insect is perfect in every other respect, the 

 costal cilia are injured so that I can not tell whether the costal ciliary 

 dark line of the other species is present or not. The palpi are white 

 with a dark brown line beneath as in Haworthana Antennae dark 

 brown, legs and tarsi dark brown, the tarsi annulate with white, and 

 the middle pair yellowish within; venter silvery white, the anal 

 tuft a little tinged with yellow. Al ex. f inch. Kentucky.
