nent. The inverted "V" space is lined and centered with an upright 

 black dash. Beyond this space is a perfect "Y" mark of the same 

 color ; between this mark and the crest band is a very conspicuous 

 upright line. There are no tubercles below the crest. Body: Color 

 light-ashen, sprinkled with black ; tapering m both directions from 

 the eighth segment. There is a mid-dorsal whitish line most conpicu- 

 ous posteriorly from the elevation on the eighth segment ; this elevation 

 has a white center with a black ring at base. All tubercles are black, 

 set in a ring of the ground color of the body; the true legs are con- 

 colorous, the prolegs are pinkish with a black oval band, centered with 

 violet. Fringes short, reddish white. The ventral surface is whitish 

 green with the usual blotches black.

 at the sides than in front. Body gray, with numerous blackish irrora- 

 tions. Longitudinal lines very narrow and much broken, sometimes 

 hardly traceable, with the intervening space somewhat paler. Eighth 

 segment with the summit of the elevation whitish. Posterior half of 

 seventh and anterior half of eighth segments at the sides pale gray. 

 Fringes at sides fleshy white. Warts black. Underside white, with 

 a black patch on each segment, between the abdominal legs. Thoracic 

 feet translucent white, with black marks on the outside. Abdominal 

 legs with an inverted, black loop on the outside of each. Length 25 mm. 



Stage V. Mature larva. — Head semitranslucent, lilac gray, with 

 whitish dots ; sides and top of head black. Body sordid gray, densely 

 covered with minute black dots, giving it a gray appearance. Warts 

 small, with the summit orange. Eighth segment with a rather prom- 

 inent elevation, black, summit pale. Dorsal warts on the last three 

 segments larger than on the others. Fringes at sides pink. Posterior 

 parts of the segments between the longitudinal lines darker than the 

 anterior half. Underside white, with a large black patch on each seg-

 Length 40 mm. Food plant — Honey locust. (Gleditsia triacanthos.) 



The descriptions of stages IV and V, as recorded by Beuten- 

 mueller for alcoholic specimens, are in every way as I have

Biological Notes. The eggs of C. minuta are deposited sin- 

 gly or in clusters, in crevices of bark on large trees, as well as 

 openly on small shrubs of the honey locust. The eggs of this 

 species are not covered with a fibrous substance as are those 

 of C. titania and C. illecta. The eggs of the latter species are 

 covered with a glossy silken mass. The habits of the larva of
