Complete Writings vol. i, page 330. 



Head, anterior lobe of the pronotum 

 and scutellum black; posterior lobe of the 

 pronotum sometimes tinged with testaceous 

 or ferruginous. Antennae and legs ferrug- 

 inous; third and fourth antennal joints 

 black, the extreme base and apex of the 

 second sometimes infuscated ; tibiae, except 

 at base and apex, whitish; tip of the tarsi 

 infuscated; rostrum, coxae and edges of 

 their sockets dark ferruginous ; metapleura 

 with a large opaque rastrate area about 

 the orifices ; posterior flap broadly whitish. 



Abdomen piceous brown, polished. Elytra soiled white, with 

 sparse large, mostly fuscous punctures; the corium very ob- 

 scurely infuscated from near the base, darker on the nervures ; 

 large disk of the membrane infuscated or almost black as seen 

 against the tergum, its nervures darker. Length 3-3 3/4 mm. 



In its structural characters this species is considered typical 

 and does not vary from the generic diagnosis given above. 



Type locality Missouri. I have taken this species in New 

 York and Pennsylvania, Mr. G. M.. Moore has found it at Mon- 

 treal and Mr. Heidemann has specimens from Washington, D. C. , 

 and Banff Springs, Alabama. Dr. Uhler records it from Utah, 

 California and Lower California. 



2- Crophius Schwarzi n. 



Basal joint of the antennae surpass- 

 ing the tip of the tylus by about one 

 third its length; fourth a little shorter 

 than the second. Metasternum some- 

 what depressed at base but hardly sulcate ; 

 callousities quite strongly elevated, al- 

 most impunctate, together forming a 

 sinuated ridge across the middle of the 

 pronotum. Claval lines of punctures 

 somewhat confused. Membrane very 

 large ; its inner nervure almost obsolete. 

 Length 3 1/2-4 mm.
