66 THE CANADIAN ENTOMOLOGIST. 



Body above semi-transparentj dull brownish green, downy with fine whitish 

 hairs similar to those on head, with a dorsal line and many dots over the sur- 

 face of body of a darker shade ; second segment pale whitish with a line of 

 brownish black across the upper surface ; terminal segments paler than the 

 rest of body. Under surface slightly paler than upper with a semi-transpar- 

 ent glossiness ; feet and prolegs whitish. 



This larva was fed on grass, from a plant growing in a flower pot, only one 

 attained its full growth — the other died while young. The full grown speci- 

 men when about to enter the pupa state, attached itself to a piece of coarse 

 gauze with which the flower pot was enclosed to prevent the escape of the 

 larva — and here while undergoing its change it was attacked from the outside 

 by à large spider which completely emptied the fresh pupa case and destroyed 

 it. No description had been taken of the pupa up to the time of this un- 

 toward event. 



Eesperia hohomoJc, Harris— Several eggs were deposited in a pill box by a 

 female specimen about the 17th of June. Color pale green, nearly round, 

 flattened on the side that is attached to the box. Under a magnifying power 

 of twenty diameters they appeared plainly reticulated with fine sis sided 

 markings, strongly resembling the cornea of a fly's eye. Two specimens 

 hatched on the 2'7th — two more on the 28th. The young larva on finding 

 its way out commenced to eat the egg shell at the centre above. 



Appearance when fresh from the egg. Length one-tenth of an inch. 

 Head large and prominent, black and shining. Body above creamy white 

 with a yellowish tinge towards the posterior segments; second segment half 

 encircled above with a transverse line of black ; under surface, feet and 

 prolegs, similar in color to upper surface. 



This larva also feeds on grass, stationing itself about the inside of the 

 leaves near the joints, drawing portions of the leaves together with silken 

 threads, forming a rude case in which it secretes itself. When placed on a 

 strong ribbed blade, the edges of which it cannot bend, it spins a few threads 

 from rib to rib, and places itself behind the threads. Mt/stic and Wamsutta 

 have similar habits. 



On the 14th of July these specimens were unfortunately lost — at this time 

 they were about three-eighths of an inch long and very closely resembled 

 Mystic of the same age. 



Mesperia toamsutta, Harris — Several eggs were deposited by a beaten 

 female July 10th, Egg pale greenish yellow, strongly convex above, flattened 

 at the place of attachment ; flattened portion slightly concave. Surface 

 appears faintly reticulated under a magnifying power of forty-five diameters. 

 On the 21st and 22nd the eggs grew darker in color, the larva appearing on 

 the 24 th.
