Head narrowly rounded behind the eyes. Hind ocelli slightly nearer 

 to each other than to the eyes. First and second articles of flagellum of 

 about the same length, with extreme base of the first testaceous, the re- 

 mainder of the flagellum nearly concolorous with the body. Mesonotum 

 with shallow remote i)unctures. Scutellum medially almost smooth, rugo- 

 so-punctate around the sides. 



Pro-and metapleurae rugoso-puuctate, the mesopleurae anteriorly 

 remotely punctured, posteriorly smooth. Metanotum with a strong reti- 

 culum, but with meshes very irregular in size and shape, the surface 

 within the meshes minutely wrinkled. Wings with three submarginal 

 cells, the second about half the size of the first, sub-ovate, and receiving 

 the two recurrent nervures, one near the base and one near the apex; the 

 third submarginal cell is subrectangular, a little wider above, and not 

 half the length of second; apical half of wings smoky, this area traversed 

 by four radiating bands of hyaline. 



Petiole not quite as long as the nodose portion of the first abdominal 

 segment. First tergite and anterior portion of second, coarsely ' ' spatter- 

 punctured ", remotely so posteriorly on the second tergite; above on pe- 

 tiole and base of nodose portion, the punctures are arranged tranversely, 

 forming distinct ridges. 



Taken at Claremont California. Apparently related to n'lbecnliis of 

 Colorado in general characters, but it lacks entirely the ventral tufts 

 said to be most strikingly characteristic of that species. 



4347 Chyphotes nevadensis u. sp. 



Length 11 mm. Rather dark ferruginous, thickly clothed especially on 

 the abdomen with ochraceous pubescence; legs pale testaceous; anten- 

 nae honey-yellow; abdomen slightly darkened apically; head concolorous. 



Head narrowly rounded behind the eyes. Hind ocelli about equally dis- 

 tant from each other and the eyes. First and second articles of the fla- 

 gellum of about the same length. Mesonotum with shallow, remote, large, 

 and ill-defined punctures. Scutellum uniformly covered with large, thickly 

 placed, but rather shallow punctures. Propleurae nearly smooth, meso- 

 pleurae anteriorly coarsely, evenly, rugoso-punctate. Metanotum with a 

 very strong, sharply defined reticulum which is quite uniform except in 

 a small area on the anterior border where it is finer and more dense; the 

 meshes are large, but very irregular in shape owing to the wavy nature 

 of the bounding ridges; the surface within the meshes is apparently 

 nearly smooth. 



Wings with three submarginal cells, the second scarcely half the size 

 of the first, subtriaugular and receiving the two recurrent nervures, one 

 just behind the middle, the other near the outer border; the third 

 submarginal cell subrectangular, a little wider above and more than half 

 the length of the second. Apical half of wings smoky, unusually dense in 

 front of the marginal cell, and with the smoky area traversed by four 

 radiating bands of hyaline.
