anterioiij' and inclining to yellow under the anal segment. 

 Prolegs and feet of the same color. It has a few short bristles 

 on tiie anterior and lateral segments. 



"The head is light brown, with a dark brown spot on each 

 side and dark brown above, leaving the inverted Y mark in the 

 middle light brown, and having much the appearance of s 

 goblet, as one looks from tail to head. The cervical shield is 

 dark brown, except a stripe above and on each side. There 

 are sparse, short, white bristles laterally and posteriorly. 

 The A'enter and legs are of a glaucous glassy color, and the 

 feet are light brown." 



"The moth in its general appearance bears a great resem- 

 blance to Hadena chenopodii, but the two are found to differ 

 essentially when compared. From specimens of H. chenopodii, 

 kindl}' furnished me by INIr. Walsh, and named by Grote, I am 

 enabled to give the essential differences, which are: 1. In 

 A. Cochrani, as already stated, the middle area exceeds some- 

 what in width either of the other two, while in II. chenopodii 

 it is but half as wide as cither ; 2. In the Agrotis the space 

 between the spots and between the reniform and transverse 

 posterior is dark, relieving the spots and giving them a 

 light appearance, whilst in the Hadena this space is of the 

 same color as the wing, and the reniform spot is dark. The 

 claviform spot in the Hadena is also quite prominent, and one 

 of its distinctive features ; while in the Agrotis it is just about 

 obsolete. 



Another larva is called b}' Mr. Riley the AV-marked cut- 

 worm. "It measures one and an eighth inches, and its gen- 

 eral color is ash gray, inclining on the back and upper sides 

 to dirty yellow : it is finely speckled all over with black 

 and brown spots. Along the back there is a fine line of a 

 lighter color shaded on each side at the ring joints with 

 a darker color. Subdorsal line light sulphur yellow, with a 

 band of dirty brownish yellow underneath. Aloug the stig- 

 matal region is a wavy line of a dark shade with flesh colored 

 markings underneath it ; but the distinguishing feature is r 

 row of black velvety marks along each side of the back, on al 

 but the thoracic segments, and bearing a general resemblance 

 (looking from tail to head), to the letter W. The ventral regiou
