me. The egg is noctuid and the larva a true 

 semi-looping noctuid in primitive first stage, 

 the single setae stiff, bulbous at tip, per- 

 fectly normal and the subprimaries absent. 

 The larva is e.^ckided from both Arctians 

 and Lithosians bv the bulbous setae, as Dr. 

 Packard has shown that no Arctian has glan- 

 dular hairs. Further the thoracic tubercles 

 remove it from the Lithosians. Again the 

 shortening of the first two pair of abdominal 

 feet never occurs in the Arctian phvlum, 

 but is characteristic of the semilooping 

 Noctuids. 



It seems evident that tlie Cvdosiinae are 

 Noctuids, the character of vein S of second- 

 aries being here deceptive, but paralleled 

 in some species of Acontia in the Noctuidae, 

 as I have had occasion to notice.

 Nonquitt, Mass., si.'i larvae of Smei-int/iiis 



as/y/iis on Andromeda ligusttiua. We had 

 never been able to make them eat anything 

 except Vacciiiittm corymbosiini and Gaylus- 

 sncia Jrondosa. We found also Samia cecro- 

 fia on Gaylnssacia froudosa ; Eacles imferi- 

 alis on Prufiiis serotiiia ; Smerini/ius myops 

 on birch, willow, and poplar; Dataiia drex-

 foUa\ H. lo on Trifolium refens ; E. clioe- 

 riliis. on Kalmia augu$tifolia. 



We found one laiva of Smerintlius myops 

 having the spots of a clear mauve color 

 instead of red or brown; and a larva of H. 

 thifhe all red except the dorsal area and first 

 segment. 



We found on elder a large sphinx larva of a 

 chocolate brown with obliques and face lines 

 of paler brown, like 5. chersis except in
