ance. The black cross-bands are either entire or broken into four 

 parts, following the yellow bands as shades to each. Some larva- 

 have the yellow without the black bands, while a few have the 

 black without the yellow. The pupa is three-fourths of an inch 

 long, plain green, with a pale lateral line. A row of small, dark 

 dots along each side, on the back, and a submarginal row on the 

 wing-cases. Length of pupal period in August is from four to 

 six days. Later in the year it is much longer. Wing-sheaths of 

 pupa humped. Two days before the pupa gives the imago the 

 wings show plainly in miniature, and the dark border of the ma- 

 ture butterfly is here represented by a bright red band, the male 

 being readily distinguished from the female. 



I doubt if this species feeds on any other plant than Ainorpha. 

 as I have never observed the female depositing her eggs on any- 

 thing else, though many other Leguminous herbs, shrubs and 

 trees grow here. 



Even the larger and older shrubs of Amorpha do not seem to 

 be inviting to the female, and she frequents fields where the brush 

 has been newly cut away from the banks of brooks, and fresh, 

 tender shoots offer a supply of suitable food for young larva-. 

 Here she deposits her eggs in great numbers, and here the col- 

 lector finds a supply of larvae. Besides ctzsonia< the caterpillars 

 of Eudamus tityrus, Hyperchiria io; an undetermined Limacodes 

 and another moth feed on Amorpha fruticosa, a very abundant 

 shrub along the prairie branches near Curryville.

Lachnosterna insperata and fraterna. 



By JOHN HAMILTON, Allegheny, Pa. 



Lachnosterna insperata Smith. The distribution of this 

 species is widely extended; examples are in my collection from 

 Sudbury, Ontario; Buffalo, N. Y. ; and from here, as likewise- 

 from various places in western Pennsylvania and eastern Ohio. 

 Prof. Smith has it from New Jersey and from Illinois. The ven- 

 tral characters of the male are variable; the form of the ridge on 

 the penultimate ventral segment of Mr. Smith's type seems to be 

 an extreme in one direction, varying in a large majority of the 

 individuals to that of dubia, and an example occasionally occurs 

 which inosculates so closely with some fuscte as not to be sepa-
