Female. — Body black with the following parts yellowish white: supra- 

 clypeal area, clypeus, labrum, mandibles, mouth-parts, genal orbits, extending 

 onto frontal orbits, vertical orbits, occipital orbits, collar, band on lateral mar- 

 gin of abdominal segments one to six, sometimes extending over all of their 

 terga and sterna, and caudal tergum ; trochanters, prothoracic and mesotho- 

 racic legs, beyond middle of femora, rufous ; clypeus narrowly, shallowly 

 emarginate ; median fovea longer than broad, deep, sides sloping; frontal 

 crest slightly broken, narrow, not elevated ; ocellar basin hardly distinguish- 

 able, lateral walls obsolete ; antennje with third, fourth, and fifth segments 

 subequal ; head and thorax not polished ; wings slightly infuscated ; costa, 

 stigma, and veins of distal half rufous, veins of proximal half black; saw- 

 guides robust, dorsal margin straight, ventral margin convex, distal portion 

 oblique, pointed. Length, 8 mm.

This species differs from gracilis Marl, in the length of the thirst 

 antenna] segment.

 thoracic and mesothoracic legs beyond proximal third of femora, metatho- 

 racic legs beyond tibiae, caudal aspect of femora more or less pale, and caudal 

 abdominal sternum; clypeus distinctly, roundly, deeply emarginate; median 

 fovea obsolete ; frontal crest almost obsolete : ocellar basin a narrow, elongate 

 depression extending from dorsad of median ocellus onto supraclypeal area, 

 lateral walls rounded, hardly elevated ; antennae with third segment slightly 

 shorter than fourth, fourth and fifth subequal ; mesoscutellum polished ; wings 

 hyaline; veins, stigma, and costa brownish; procidentia narrow, short, rounded, 

 convex. Length, 4.5 mm. 



Habitat: Orono, Maine. Sub. 27. 



This species runs in Marlat's tables to the species of Amauro- 

 nematus to horcalis. 



Pachnematus rarus new species. 



Female. — Body black with the following parts yellowish white : supra- 

 clypeal area, clypeus, labrum, mandibles, mouth-parts, genal orbits, pronotum, 

 tegulae, oblique mark on pleurae, legs, venter of abdomen, and caudal tergum ; 

 following parts rufous : occipital, vertical, and frontal orbits, margins of me- 

 dian lobe of mesonotum faintly, mesoscutellum faintly, and caudal abdominal 

 terga more or less ; yellowish white of abdominal sterna sometimes extending 

 onto lateral portions of terga ; clypeus distinctly but shallowly, roundly emar- 

 ginate ; median fovea rather indefinite, broad and shallow ; frontal crest not 

 distinct, broken, narrow ; ocellar basin flat, lateral limiting walls rounded, 

 identifiable but rather indefinite ; antennae with third, fourth, and fifth seg-
