Described from two male specimens from Austin, Texas, and 

 one male from Rochester, Wisconsin. 



One of the Texas specimens was found under a stone, entan- 

 gled in the web of the southwestern variety of Agelena navia 

 Bosc., apparently just after issuing from the body of the spi- 

 der. The shrivelled spider was lying close by, with a round 

 perforation near the base of the under side of the abdomen. 



Were it not for the great variability in the neuration of the 

 members of this family, this species might be thought out of 

 place in Opsebius. As it, however, presents the characteristic 

 habitus, the discrepancies in the costal tooth and widely open 

 anal cell are insufficient to exclude it from the genus. More- 

 over, we may recall that in sulphuripes the anal cell is narrowly 

 open, showing a trend in the direction of agclenfe, while in 

 Pterodontia the costal projection is quite variable in size, and 

 even in Opsebius diligens the costa shows a thickening beyond 

 the first vein. 



9. Ealonchus smaragdinus Gerstaecker. 



Two green females, measuring 8 and 10 mm., were taken in 

 Marion Co., Calif. 



10. Eulonchus sapphirinus Osten Sacken. 

 One male from Marion Co., Calif. 



11. Ealonchus tristis Loew. 



As this species seems to be relatively common in Idaho, ac- 

 cording to Prof. Aldrich, Eulonchus can no longer be regarded 

 as exclusively a Californian genus. The males have the third 

 joint of the antennae sharp at the apex ; in the female it is 

 scarcely attenuate and rather blunt. One female from Marion 

 Co., California, has the abdomen brassy green; a pair from 

 Idaho (Juliaetta and Craig's Mt.) are blue-black. There is a 

 great inconstancy in the juncture of the veins beyond the tip 

 of the discal cell. In the California specimen the vein separa- 

 ting off the second submarginal cell is angulated near its base, 

 and bears a short spur at the angulation ; while in the Idaho 

 specimens this vein is evenly bisinuate, although it bears a 

 similarly-placed short spur. The males have the second sub- 

 marginal cell petiolate at the base ; in the female it is pointed
