oration ; along ventral side two rows of small orange spots corresponding 

 to the small basal tubercles of the larva ; the wing case shows a large 

 black patch on disk, also irregularly serrated marginal black spots, and 

 submarginal spots, rounded and sub-lanceolate ; head case largely black ; 

 on anterior part of mesonotum a large black sub-rectangular patch, below 

 which is an arched stripe of black, and under this, at summit, two spots ; 

 on the posterior part two curved demi-bands meeting at the carina. 



From this chrysalis came a female butterfly 23rd May. Duration of 

 this stage 10 days. 



Another larva went to pupa and imago in Philadelphia, in Mrs. Peart's 

 care. The other larvae from the first eat little, and some became lethargic, 

 and some of them died. But one seemed healthy and asleep, and 23rd 

 May I returned it to the ice box. From time to time I looked at it ; on 

 6th July brought it to my room and laid it on Chelone leaf. But as by 

 8th it had eaten nothing, though it had moved a little in the glass, I re- 

 placed it on the ice. As I write, 20th Aug., it is sweetly sleeping. It 

 seems odd that a larva in this climate should go over the second season, 

 as this bids fair to do. 



Rubiainda belongs to the Anicia sub-group, flies from North California 

 at least to Vancouver Island. I have had mature larvcc of Anicia and 

 of Bar 0711 (another of this sub-group), and the three species are distinctly 

 different in this stage. They all have similar habits as far as I know 

 them, and probably all will eat the plant of Fhaeto?i, Chelone glabra, as 

 Chalcedon also does.

A special interest attaches to the question of the mode of life in insects 

 in relation to their surroundings in high Northern latitudes. Knowing, 

 as we do, that the time available for the development of an insect in the 

 extreme North is limited to from 4 to 6 weeks in the year, one has felt
