the next season. Most of the insects come forth soon after the four- 

 teenth day, but some are delayed and appear during the ensuing months. 

 Several hundred specimens bred by myself in Farmington, Conn., came 

 forth mostly in August. If there is a second brood in September, tlie 

 numbers must be comparitively small, for I have not seen them nor anv 

 fresh cocoons late in the season. Dr. Harris states that the cocoons 

 are mostly formed on the ground among the roots of plants. But in 

 the above instances very few were found except upon the branches of 

 trees. When the insect comes forth from the cocoon it cuts a circular 

 piece from on one end as cleanly as with a knife. This eometimes re- 

 mains as a sort of lid. This larva is very destructive, remaining fin- 

 several years in a region and causing the foliage of the fir trees to ap- 

 pear brown as if burnt by fire. 



From the cocoons of L. ahiefis, I have bred the following parasitical 

 insects, viz : 



1. Ichneumon riihictnirfiia, Cresson. 



2. Ichnc avion fungor, Norton. 



3. Cri/ptus Lophj/ri. n. sp. '

5. Jlemiteles titilis, n. sp. ~ 



1. Cryptus Lophyri, n. sp. — Length 0.30, with ovip. 0.35. Br. wings 0.50 inch. 

 9 — Color black, part of abdomen rufous. Antennae three-fourths the length 



of body, about 30-jointed; color dark rufous, palest on 3rd and 4th joints, and

 of 11th joints (the annulus is almost complete). Head and thorax black, punc- 

 tate: a pale narrow line, partly or wholly interrupted in middle down each in- 

 ner orbit; tegulte and points at the two sharp augulats corners of metathorax, 

 sometimes also the scutel and post-scutel yellow; abdomen rufous upon the 

 petiole, the 2nd and basal half of 3rd and sometimes all of 3rd segments and 

 the apical edge of the following segments; the remaining segments black, except 

 the apex, which is white; legs rufous, the hinder pair darkest; the apex of hind- 

 er femora, tibiae and tarsi black, with a band at base of their tibiae and base of 

 first tarsal joint; wings hyaline. 



'^ — Antennae black, without annulus, 2nd basal joint rufous beneath ; the in- 

 ner orbital line unbroken; nasus and mandibles yellow; tegulae, edge of collar, 

 scutel and post-scutel, the basin of metathorax, except a spot at reception of pe- 

 tiole, yellow; abdomen rufous, but darker or blackish toward the apex, with a 

 more or less distinct whitish spot on the apical segment; hinder tarsi all yel- 

 low except a spot near the base of 1st joint and the claw-joint, which are black. 



Connecticut. Fourteen 9 and seven % bred. 



2. Hemiteles utilis, n. sp.— Length 0.15, Br. wings 0.25 inch. 



9 — Color honey-yellow, apex of abdomen black, wings with two brown bauds. 

 Antennse nearly aS long as body, about 21 -jointed, color of body, darker toward 

 apex, base of each joint blackish: eyes slightly diverging below; head and 

 body of one color as far as middle of 3rd abdominal segment, beyond which it
