After moulting on the I7th, the larvae were three-fourths of an inch 

 long. Very dark brown, almost black, striped longitudinally with 

 light and black lines. Head round and colored as body. True and 

 prolegs light or flesh color. A mid-dorsal row of triangular whitish 

 spots. No dorsal hump. 



After the moult on the 2ist, the larvae were over an inch long, 

 dark brownish gray with large round head, slightly lighter, not dish- 

 ed in front as in aholibah, and the cara group. A line of small light 

 reddish brown mid-dorsal triangles w_ith the vertical angle toward 

 the head. True legs cream color. No apparent row of lateral setae. 



After moulting the last time, the larva was gray-brown with large 

 round head, white and brown mottled. True and prolegs flesh color. 

 Tubercles light reddish brown. Tubercular bristles rather strong. 

 No lateral setae. 



The grown larva of residua is from 2 l / 2 to 2^4 inches long, light 

 grayish brown, streaked longitudinally with black and cream color. 

 Whole surface with black dots and broken black lines. No dorsal 

 hump or lateral setae. Tubercles light straw color. True legs faint- 

 ly pinkish. Prolegs flesh or straw color. Head round, not lobed, and 

 with pale red brown linear mottling. The top of the crest over the 

 8th abdominal segment straw color. Under side of body white with 

 the usual row of mid-ventral round black spots with hardly a sur- 

 rounding tinge of red. The tubercular bristles strong. 



The colony was fed on pecan. The first larvae began spinning June 

 6th. The first imagoes appeared July 5th, twenty-nine days from the 

 time the larvae began spinning. A larva of residua taken under 

 hickory bark in the woods was over two inches long, very light gray 

 with a mid-dorsal row of light triangles surrounded by dark brown, 

 almost black. A dark brown, almost black spiracular band. Head 

 light gray with pale reddish brown mottling. Stiff tubercular bris- 

 tles but no lateral setae. Under side of body whitish-green with the 

 mid-ventral row of smoky black spots. No humps. Prolegs faintly 

 greenish. True legs pale. No facial dash but with a black splotch 

 either side of the mouth. This larva was much lighter in color than 

 the brood of larvae bred from the egg but the imago differed little 

 from other residua. 



Supposed Diseased Eggs of Thyridopteryx ephemeraeformis 

 Haworth and Record of Parasites (Hym.) 



Among a number of eggs of this species obtained during the winter 

 of 1900-1901 there were some which appeared to be diseased in other- 

 wise healthy masses. These were coffee-colored with irregular black- 

 ish markings, and afterward no evidences of eggparasitism by insects 

 were obtained. From many of the overwintered bags Catolaccns thyri- 

 dopterygis Ashmead was obtained and a few Smicra manac Riley. 

 The latter seemed to be the host of the Catulaccus. A. A. GIRAULT.
