silvery streaks, one on the costal and one on the dorsal margin, the latter 

 a very little before the former, and both strongly dark margined before and 

 behind, their anterior dark margins meeting just behind the middle of the 

 wing, where they are somewhat posteriorly angulated. The silvery streaks 

 are not confluent, being separated by the anterior point of a dark brown 

 dorsal patch, placed behind the dorsal streak. This dark brown dorsal 

 patch is common to all species of the genus now known, and in all of 

 them it forms the posterior margin of dorsal silvery streak, and becomes 

 confluent with the posterior dark margin of the costal streak also ; the 

 anterior dark margins of both silvery streaks are margined faintly before 

 with pale golden, much less distinct and covering much less space than 

 in splendorifcrella ; behind the posterior dark margin of the costal streak 

 is a small golden patch, as in sphndoriferclla^ containing a small black 

 dorsal streak (or, perhaps more correctly, margined by it.) In perfect 

 fresh specimens of splendoriferella the extreme costa in this golden spot is 

 always more or less streaked longitudinally with dark brown scales ; these 

 dark brown streaks are absent in this species, and besides, in splendoriferella 

 the anterior dark margins of the costal and dorsal silvery streaks are not 

 confluent and posteriorly angulated as in this species, but are separated 

 by a narrow golden line, which is carried backwards between the silvery 

 streaks themselves, thus connecting the golden patch before the streaks 

 with the costal golden spot behind the streaks ; in this species they are 

 not so connected. Mr. Stainton,in a note on splendoriferella, in his edition 

 of the Clemens papers, states that the silvery costal and dorsal streaks 

 are confluent in that species, I have never found them so, but always 

 under a good lens I find them separated by the narrow golden line as 

 above stated. In splendoriferella the dark brown dorsal spot is separated 

 from the fan-shaped apical spot by a narrow projection of the costal golden 

 spot, which extends to a small spot of silvery scales on the dorsal edge 

 of the apical spot ; but in tliis species this golden projection is only 

 represented by a small golden spot, which is separated from the costal 

 golden one by a narrow blackish line, which extends from the brown 

 dorsal spot to a small silvery spot at the beginning of the fan-shaped 

 apical spot. As in all the other species, there is also a small silvery spot 

 on the costal side of the fan-shaped apical brown patch, as well as one 

 on the dorsal side, and the one at its beginning. The fan-shaped apical 

 brown patch is traversed across its middle (between the two silvery spots} 

 by a streak of paler brown, thus dividing it into two velvety black 

 (rather than brown) spots. As in splendoriferella, there is a narrow brown-
