most part distad of pedicel, pronotuni broadly, tegulse, margins of lobes of 

 mesonotum, cephalic portion of mesoscutellum, dorsal half of pleurae, legs ex- 

 cept fuscous ring on metatibiae and fuscous metatarsi, and abdomen for most 

 part; clypeus, labrum, collar, tegulse, and proximal portions of legs paler, other 

 parts more reddish ; clypeus slightly roundly emarginate ; median fovea incon- 

 spicuous, broad slightly depressed area ; frontal crest broad, short, transverse, 

 not elevated; ocellar basin not sharply defined, extending around median 

 ocellus ; antennae with third and fourth segments subequal, fifth slightly 

 shorter; head and thorax dull; wings hyaline; veins, costa, and stigma yel- 

 lowish ; saw-guides with dorsal margin concave, ventral margin convex, distal 

 portion convexly rounded, oblique, bluntly pointed. Length, 6 mm. 

 Habitat: Orono, Maine. Sub. T33. 



This species belongs near fiilvipcs Nort.. but is differently colored. 



Amauronematus visendus new species. 



Female. — Body black with the following parts white : clypeus, labrum, 

 mandibles, genal orbits, extending onto adjacent orbits, supraclypeal area, 

 pronotum on each side with a central black area, and trochanters ; following 

 parts rufous : occipital and vertical orbits, prothoracic and mesothoracic legs 

 beyond middle of femora, basal plates except at middle, and abdomen except 

 caudal segment and saw-guides : clypeus narrowly shallowly emarginate ; me- 

 dian fovea an elongate pit ; frontal crest not definite, slightly broken by exten- 

 sion from median fovea ; ocellar basin a general depression ventrad of median 

 ocellus, lateral walls obsolete ; antennae with third segment distinctly shorter 

 than fourth, fourth slightly longer than fifth ; head and thorax not polished ; 

 metapostscutellum polished ; wings slightly infuscated ; veins and costa black- 

 ish, stigma reddish ; saw-guides with dorsal margin straight, ventral margin 

 straight, and converging, distal end oblique. Length, 7 mm. 



Male. — Body black with following parts white : clypeus, labrum, genal 

 orbits, mandibles, distal portion of profemora and mesofemora, and protibiae 

 and mesotibiae in great part ; small rufous spot on vertical orbits ; procidentia 

 minute, convex, rounded. Length, 6 mm. 



Habitat: Orono, Maine. Subs. 16, 29. 



This species runs to lutcotcrgum Nort. The form of the clypeus 

 and frontal crest will differentiate it from this species. 



Amauronematus vacivus new species. 



Male. — Body black with the following parts yellowish white, inclining to 

 white : head entirely except area included between antennal furrows, extending 

 to frontal crest and expanded upon occiput, pronotum, tegulae, spot on each 

 side of median lobe of mesonotum, pleurae, margins of mesoscutellum, legs ex- 

 cept slightly infuscated metatarsi, venter of abdomen, spots on sides of terga, 

 inclining to reddish, larger on caudal segments ; clypeus slightly narrowly 

 emarginate, almost truncate ; median fovea a minute pit ; frontal crest not
