gillettei this band is narrower, nearer apices of clavi and slopes obliquely back- 

 ward, not forward. 



One 9 specimen, Digby Co., N.S., Aug. 18, 1918. 

 Typhlocyba querci ^ ar. grata, new variety. 



Scutellum dusky; elytra with a large dusky saddle-spot, occupying most of 

 the clavi, and a portion of each adjoining corium; no posterior band or clouding. 



One 9 specimen, Digby Co., N.S., Aug. 14, 1918. 



Typhlocyba querci a ar. scripta, new variety. 



Scutellum chiefly dusky; elytra with dusky bands at middle and on cross- 

 veins, as in var. gillettei, apical cells smoky, and with a longitudinal dusky stripe 

 on clavus and overlying claval suture connected with band over cross-veins. 

 These markings leave the margin anteriorly and the tip posteriorly, of the clavus, 

 of the ground colour.

V DESCRIPTIONS OF FOUR CATOCALA LARV^. 



BY R. R. ROWLEY, LOUISIANA, MO. 



Among a number of mature Catocala larvae, taken under the bark of hickory 

 trees in the early part of last summer, a dozen or more proved of unusual in- 

 terest, one a lachrymosa, previously undescribed, another a typical obscura, a 

 third and fourth showing the slight differences between the closely related 

 species retecta and flebilis, while still another gave jndith, but the description 

 was misplaced. 



Other larvae were of angusi and its variety lucetta, hardly distinguishable 

 from habilis. Of six angusi moths, five were var. lucetta, only one being a typical 

 angusi; a like ratio existing in the woods here between the variety and present 

 form. The species, however, is usually rare. 



Catocala flebilis. — Mature larva 2}/^ inches long, leaden gray with lighter 

 tubercles. The mid-dorsal band lighter than the general body colour, con- 

 stricted at the segment edges, forming a series of spots of chain-link appearance. 

 The spots on the first, second and fifth abdominal segments bordered by a black 

 encircling line (on three sides). A dark cross-band covers the back half of the 

 fifth abdominal segment. A black-cross line behind the eighth abdominal seg- 

 ment. The sublateral line or narrow band is dark or quite black above the 

 spiracles. True and pro-legs general body colour. The lateral line of setae 

 composed of so few and short bristles as to be hardly noticeable. Head gray, 

 round, with short lateral mouth dash of black. 



Ventral colour soiled white with faint red blotches about the row of mid- 

 ventral black spots. Larva taken under bark of Carya alba (shag-bark hickory). 

 Cocooned June 15th, and gave imago July 20th. 



Catocala retecta. — Mature larva 2'/4 inches long, dark leaden brown. A 

 mid-dorsal longitudinal "chain link" like narrow band, a little lighter than the 

 general body colour. Still narrower bands of darker hue bound the mid-dorsal 

 band and, beginning with the second abdominal segment, these bounding bands
