white pubescence. There is a stout longitudinal keel on the upper half of 

 the face; the oral region is striated; there is a fine blackish keel on the 

 malar space. Thorax covered with white glistening pubescence; the pro- 

 thorax smooth; the mesonotum and scutellum closely distinctly punctu- 

 red; the middle lobe of the mesonotum does not reach to the scutellum, 

 is raised and at the apex is gradually narrowed to a point. The pleurae 

 are more shining and less strongly punctured; there is a distinct longi- 

 tudinal furrow on the apical two-thirds of the meso-pleurae close to the 

 sternum. The scutellum is more strongly punctured than the mesonotum, 

 the furrows bounding it are distinct and deep. Ovipositor very short, 

 broad and white. 



Cryptinae. 



Erythrocryptus gen. nov. 



Areolet large, 5 — angled. Radial cellule short. Disco-cubital nervure 

 broken by a stump of a nervure. Transverse median nervure received 

 shortly behind the transverse basal. Transverse median nervure in hind 

 wings broken below the middle. Metathoracie spiracles small, oval, about 

 twice longer than wide; there is a distinct basal keel and an apical one 

 indicated only at the sides. First abdominal segment longer than the se- 

 cond; it becomes gradually widened towards the apex. Parapsidal furrows 

 narrow, not extending much lioyond the apex. Clypeus rounded at 

 apex. 



Labrum large, rounded, the sides and apex forming a broad rim, the 

 depressed center smooth and shining. Metathorax as long as wide. An- 

 tennae long, the first joint of flagellum longer than the second, ringed 

 with white. Colour uniformly rufous. Ovipositor short. Legs slender, the 

 fore tarsi twice the length of the tibiae. The middle segments of the 

 abdomen are punctured, the apices of the second and third are raised. 

 Metapleural carina complett. Temples obliquely narrowed. The apex of 

 the metathorax is not quite transverse, being depressed in the middle. 

 Spiracles of the first segment placed near the base of the apical third. 



In Dr. Ashmead's arrangment (Bull. U. S. Nat. Mus. XXIII, 41-42) 

 this genus comes in near Ilabrocryptus and Iciiolispn. 



3964 Erythrocryptus rufus sp. nov. 



Ferruginous, the inner orbits narrowly and clj-peus yellow; the flage- 

 llum of antennae black, the scape brownish below, joints 7-9 white. Wings 

 hyaline, the stigma testaceous, the nervures blackish. Female. Length 7 

 mm., terebra 1.5 mm. Taken in the mountains near Claremont, California. 



Vertex weakly punctured in the center; the front closely irregularly 

 transversely striated. Face closely wrinkled-punctured. Pro-and meso- 

 thorax closely, distinctly punctured; the propleurae striated in the mid- 

 dle; the mesopleurae finely striated in the center; the upper side of the 

 metapleurae beyond the spiracles somewhat strongly obliquely striated. 

 The second and third segments of the abdomen are closely distinctly
