West Virginia, Illinois, Ontario, Colorado, California. Food, 

 blackberry. This species has been bred from blackberry by Prof. 

 William Saunders and also by Prof. S. A. Forbes. 



'< About the middle of June the larva reaches full growth, when 

 it is about four-tenths of an inch long, of a pale greenish-yellow 

 color, streaked with pale yellow, and with transverse rows of 

 shining tubercles, from each of which arise from two to six 

 spreading hairs of a yellowish-green color. The head is small, 

 pale green, with a faint brown dot on each side. 



" When the larva is about to change to a chrysalis, it spins a 

 loose web of silk on a leaf or other suitable spot, to which the 

 chrysalis is attached. This is less than three-tenths of an inch 

 long, pointed behind, enlarging gradually towards the front, 

 where, near the end, it slopes abruptly to the tip. Its color is 

 pale green, with a line along the back of a deeper shade, margined 

 on each side with a whitish ridge ; it is also more or less hairy. 

 In about a week or ten days the chrysalis changes to a darker 

 color, shortly after which the perfect insect escapes." (Saunders.) 



GENUS PLATYPTILIA Hiib., Verz. bek. Schm., p. 429 (1826). 



Front with a conical projection, covered by a longer or shorter 

 tuft of scales. Labial palpi long, slim, porrect or slightly ascend- 

 ing, closely scaled, the third segment filiform and shorter than the 

 second. Legs long and slim, the tibia? with darker scales and 

 sometimes thickened at the end and also in the middle of the hind 

 tibiae. 



Fore wings fissured about one-third of their length, the lobes, 

 especially the second, wider at the outer end than at the base, 

 each with a distinct anal angle, the first falcate and the second 

 convex on the outer margin. The cell is nearly rectangular at the 

 outer end, and veins 5 and 6, as well as the cross vein, are very 

 weak. Two internal veins are present. Vein 2 arises from the 

 outer third of the median vein and ends in or near the anal angle 

 of the second lobe, while vein 3 ends in the middle and 4 in the 

 apex of the same lobe. Vein 7 arises a little below the anterior 

 angle of the cell and ends in or near the anal angle of the first 

 lobe; 8 and 9 are from a stalk which arises from the anterior 

 angle of the cell, and 8 ends in the apex, while 9 ends in the 

 costa; 10 and 11 are somewhat remote from each other and from 

 the stalk of 8 and 9. The first feather of the hind wings has a 

 blunt apex, and is wider towards the outer end than at the base. 

 Veins 7 and 8 arise separately from the base of the wing, approach
