each lateral lobe of mesonotum, mesopostscutellum in part, abdominal terga 

 one to four irregularly on meson, ring on metatibise, and distal half of meta- 

 tarsi ; antennae with fourth segment longer than third and fifth segments ; 

 clypeus deeply, narrowly, roundly emarginate. median fovea shallow, broad, 

 not well defined ; frontal crest narrow, indefinite, broken ; ocellar basin flat, 

 depressed, lateral walls rounded, not sharply defined ; head and thorax pol- 

 ished ; wings infuscated or brownish ; veins brownish, stigma and costa luteous ; 

 saw-guides with dorsal margin straight, ventral margin straight, converging 

 caudad, distal portion convexly bluntly rounded, pointed above. Length, 8 mm. 

 Habitat: Orono, Maine. Sub. 252. 



This species belongs in the group with suadiis Cress., affinis Marl., 

 and riifocUictns MacG. Color, form of median fovea, and frontal 

 crest will distinguish them. 



Pachynematus remissus new species. 



Female. — Body black with the following parts whitish : margin of clypeus, 

 labrum, mandibles, collar, tegulse, coxae except at proximal end, trochanters, 

 proximari and distal ends of profemora more or less, protibise, mesotibiae, 

 proximal one-fourth of metatibiae, probasitarsi, mesobasitarsi, and venter of 

 abdomen except caudal sternum, extending onto lateral portions of terga ; 

 clypeus broadly shallowly emarginate, almost truncate ; median fovea deep, 

 broad ; frontal crest not prominent, distinct, linear, dorsal margin three-sided ; 

 ocellar basin depressed, distinct, lateral walls distinct, linear ; antennae with 

 third segment longer than fourth and fourth slightly longer than fifth ; head 

 and thorax setaceous ; wings hyaline : veins and stigma brownish, costa pale ; 

 saw-guides stout, dorsal margin straight, ventral margin straight, oblique, 

 distal end blunt. Length, 7 mm. 



Habitat: Ithaca, New York. Nos. 150-3, 150— i, 150— i-i. 



This species differs from paUiventris Cress, in the form of its 

 median fovea, frontal crest, and ocellar basin. 



Pontania dedecora new species. 



Female. — Body black with the following parts luteus : head except small 

 area around each ocellus, pronotum, tegulae, and legs except metacoxae in part, 

 fuscous ring on metatibise, and distal half of metatarsi ; clypeus deeply nar- 

 rowly emarginate ; antennae with third segment longer than fourth and fourth 

 longer than fifth ; median fovea shallow, broad, continuous with ocellar basin ; 

 frontal crest indefinite ; ocellar basin distinct, lateral walls linear, closed 

 caudad of median ocellus ; head and thorax not polished ; wings hyaline ; veins 

 and distal half of stigma brownish, proximal half and costa pale; saw-guides 

 with dorsal margin straight, oblique, ventral margin convex, distal portion 

 concave, pointed above. Length, 4.5 mm. 



Habitat: Ithaca, New York. Nos. 18532, 8.si(?)-i-i.
