By Alex. D. MacGillivray, Urbana, Ills. 



The adults of the following new species were all bred from 

 larvae. The species from Maine were bred by the Maine Agri- 

 cultural Experiment Station of Orono, Maine, and the species 

 from New York were collected at Ithaca by Dr. Hachiro Yuasa. 



Blennocampa abjecta n. sp. 



Female — Body black with the following parts white : tro- 

 chanters, ring on proximal and distal ends of profemora and 

 mesofemora, protibi?e, mesotibias, and tarsi ; clypeus convex, 

 truncate ; antennae with third segment longer than fourth and 

 fourth slightly shorter than fifth ; front without V-shaped 

 furrow, depression surrounding median ocellus ; ocellar basin 

 wanting, also frontal crest and lateral walls of ocellar basin ; 

 median fovea wanting ; lateral f oveae distinct, broad, shallow ; 

 wings infuscated, particularly the pioximal two-thirds; -veins, 

 costa, and stigma blackish ; saw-guides broken. Length 4.5 

 mm. 



Habitat: — Ithaca, New York, No. 71-1. 



This species is related to ahnorma MacG. The form of the 

 clypeus will distinguish it. 



Blennocampa absona n. sp. 



Female — Body black with the following parts white: tro- 

 chanters, distal ends of profemora and mesofemora, protibise, 

 mesotibise, proximal one-fourth of metatibiae, and tarsi : clypeus 

 convex, apparently truncate ; antennae with third segment longer 

 than fourth, not as long as combined subequal fourth and fifth 

 segments ; front without V-shaped furrow, slight depression 

 surrounding median ocellus ; median fovea minute inconspicu- 

 ous puncture ; head uniformly convex, frontal crest, ocellar 

 basin and its lateral walls obsolete ; lateral fovea shallow, con- 

 nected with antacoriae ; wings infuscated, particularly the proxi- 

 mal two-thirds; veins, costa, and stigma blackish: saw-guides 

 with dorsal margin straight, ventral margin broadly rounded, 

 distal end bluntly rounded. Length 5 mm. 

 Habitat : — Orono, INIaine. Sub. 186. The lan^ae of this species 

 were collected bv the author on the leaves of the common Even-
