Coekerell has apparently shown that his genus was published a 

 few hours earlier and his name is accordingly used here. 



Hypomiscophus aenescens n. sp. 



Male : Length 4.25 mm. ; wing 3 mm. 



Black; face, front, and vertex, and thora.x witli dull bronzy re- 

 flections ; mandibles rufopiceous apically, flavotestaceous basally as is 

 the anterior margin of the clypeus ; legs with the incisures and the 

 hind tarsi obscurely testaceous; wings subhyaline, iridescent, apically 

 infuscated ; the nervures brownish except costa which is blackish. 

 Face to front, occiput, and margins of tergites with conspicuous ap- 

 pressed pubescence appearing silvery in certain lights, elsewhere there 

 generally lies conspicuous fine appressed pubescence. Clypeus with 

 the middle lobe truncate apically, convex on the disk, not carinate ; 

 front with a feeble impressed line reaching two-thirds the distance 

 from the antennal sockets to the anterior ocelli. Eyes convergent 

 above ; ocelli in an acute triangle, anterior ocellus larger, posterior 

 ocelli a little nearer the eye-margin than to each other. 



Pronotum about as long as the mesoscutum, its sculpture micro- 

 .scopically wrinkled longitudinally in front, transversely behind ; the 

 mesonotal sculpture is granulo-punctate ; mesopleura similar ; scutel- 

 lum and metanotum similar; propodeum finely transversely striolate, 

 the median longitudinal raised line distinct ; sides of propodeurn 

 longitudinally striolate ; the posterior face with a triangular fovea 

 above, on either side of which are three or four strong short parallel 

 transverse ridges. 



Abdomen with the tergites tessellate ; apices of sternites 2-6 with 

 a few erect spines. 



Hind and middle tibiae with a few black spinules ; nervulus in- 

 serted nearly its length before the basal nervure. 



Described from a single male with the antennae missing 

 taken at Pamelia Lake on Mt, Jefferson, Oregon, July 16, 

 1917 (Bridwell). Type in author's collection. 



Evidently related to nigrescens Rohwer, but the pro- 

 podeum appears from the description to be much more strong- 

 ly striolate in aenescens as well as the head and thorax being 

 bronzy in aenescens and black in nigrescens. 



Hypomiscophus timberlakei n. sp. 



Female : Length 6.75 mm. ; wing, 4 mm. 



Black ; scape piceous apically ; tegulae black, piceous apically ; mandi- 

 bles obscurely flavotestaceous, rufopiceous at apex; abdomen ferru- 

 ginous apically and the ba.sal segment more blackish; tarsi dull reddish;
