segment, which is dark brown, as is also the tuft at the end of the 

 second segment. Antennae grayish beneath, blackish above and 

 dotted with white. Thorax brown, much lighter posteriorly. 

 Abdomen dark brown, with diverging white lines on some of the 

 segments. Legs striped with dark brown and white, with a tuft 

 of dark scales at each pair of spurs ; tarsal segments white at the 

 base and brown at the outer end. 



Fore wings with the fissure extending in one-half of the length 

 of the wing, dark cinnamon brown'. An oblique stripe of pale 

 yellow or white crosses the basal third of the first lobe, cutting the 

 brown fringe on each side of the lobe. Traces of this stripe are 

 sometimes seen on the second lobe, especially in the fringe on the 

 hind margin. There are also indications of a second stripe on 

 the outer third of the lobes, as shown by a few light scales and 

 the white in the fringes, which are dark elsewhere except on the 

 apical end of the costa. Hind wings and fringes dark brown, 

 with a cluster of black scales in the hind fringe a little beyond the 

 middle, preceded by white, and the fringe at the apex is also 

 white. 



I have carefully compared four examples of californicus, given 

 me by Lord Walsingham, with seven eastern examples of lobidac- 

 tylus Fitch, and can see no difference except in the ground color, 

 which is considerably lighter in the former ; but, as the geuitalia 

 are absolutely alike in both, I must consider californicus only as a 

 variety. Lord Walsingham doubtfully referred this species to the 

 genus Aciptilus, but it seems to me to agree better with the char- 

 acters of Triclioptilus. 



Habitat. Massachusetts, Connecticut, New York, Colorado, 

 California. Food, Solidago canadensis. 



I have been informed by Mr. Fish that Mr. N. Coleman of Ber- 

 lin, Conn., has bred this insect from this plant.

Fron.t smooth, without projection ; labial palpi longer than the 

 head, ascending, the second segment with appressecl or projecting 

 scales beneath, sometimes forming a short tuft at the apex, ter- 

 minal segment filiform. Legs long and slim, the anterior and 

 middle tibiae thickened with scales at the middle and end. Fore 

 wings fissured nearly to the middle, the first lobe narrow, curved 

 somewhat at the end and terminating in a point without a defined 

 anal angle. Second lobe with the apex somewhat produced, and
