XXxii, '21] ENTOMOLOGICAL NEV.S 49 



aspect of profemora in great part, distal ends of mesofemora and 

 metafemora, tibiae except fuscous distal one-fourth of metatibiae, tarsi 

 except fuscous metatarsi ; clypeus broadly roundly emarginate ; median 

 fovea small, oval, shallow depression ; frontal crest narrow, fairly 

 strong, unbroken ; ocellar basin flat, lateral walls linear and distinguish- 

 able in certain lights ; antennae with third segment longer than fourth 

 and fourth longer than fifth; head and thorax polished; wings in- 

 fuscated, distal one-third clearer than proximal two-thirds ; costa, veins 

 and stigma brownish ; saw-guides with dorsal margin straight, ventral 

 margin straight, distal portion convex and oblique. Length 5 mm. 



Habitat : Onekama, Michigan. Bred by the author from 

 larvae on Popnlns. 



This species can be separated from pacatns MacG. by the 

 form of the median fovea. 



Trichiocampus palliolatus n. sp. 



9 . Body black with the following parts white : trochanters, cephalic 

 aspect of profemora in great part, distal ends of mesofemora and 

 metafemora, tibiae except fuscous distal end of metatibiae, and tarsi 

 except fuscous metatarsi ; clypeus broadly shallowly emarginate, almost 

 truncate ; median fovea subquadrangular, broad, comparatively deep ; 

 frontal crest not strong, not decidedly thickened, unbroken ; ocellar 

 basin not strongly depressed below area bearing median fovea, lateral 

 walls inconspicuous, linear in certain lights ; antennae with third 

 segment longer than fourth and fourth longer than fifth; wings in- 

 fuscated, proximal two-thirds darker than distal one-third; saw-guides 

 with dorsal margin convex, ventral and distal margins convex and 

 oblique, blunt. Length 5 mm. 



Habitat: Ithaca, New York. No. 154-1-1. 



This species is similar to pacatus MacG. but can be separated 

 by the form of the frontal crest and the clypeus. 



Priophorus modestius n. sp. 



9. Body black with the following parts infuscated white: tro- 

 chanters, distal one-third of profemora, ring on distal end of meso- 

 femora and metafemora, tibiae except ring on distal end of mesotibiae 

 and metatibiae, and tarsi for the most part ; clypeus shallowly roundly 

 emarginate ; median fovea broad, round, shallow, inconspicuous ; frontal 

 crest narrow, hardly raised, linear, unbroken ; ocellar basin flat, lateral 

 -vails rounded, appearing linear in certain lights ; antennae with third 

 a. id fourth segments subequal, fourth longer than fifth; wings slightly 

 in 'uscated, not smoky; veins, costa and stigma brownish, spinulae 

 prominent ; saw-guides retracted. Length 5.5 mm. 



Habitat: Orono, Maine. Sub. 100. 



This species is readily distinguished from solitaris Oyar by 

 the form of the median fovea.
