rounded; the keels sire roundly (•urvc<l; in the centre of the area is a 

 narrow keel, which reaches to the narrowed apical part; on either side 

 of it, near the middle, are two small irregular striae; the sides of the 

 metanotum are closely rugosely punctured and more or less obliquely 

 striated; the apex behind the keel is depressed and stoutly striated, the 

 striae clearly separated. The area is longer than its width at the base. 

 Centre of pronotum stoutly punctured. There is a row of punctures 

 along the base of the niesonotum; the sides bear large irregularly scat- 

 tered punctures. In the centre of the scutellum are three large punctures 

 in a line; the sides are irregularly punctured. Propleurae closely, strong- 

 ly punctured, the upper half of the apex smooth, the lower striated. 

 Mesopleurae strongly and closely punctured. Metapleurae closely striat- 

 ed except at the base below. Abdominal segments, except the last, close- 

 ly punctured. Wings hyaline, the nervures and stigma black; the basal 

 abscissa of the radius, if anything, longer than the second. Middle 

 of mandibles rufous. Female. Length 9 mm. Ormsby county, Nevada. 



Legs thickly covered with white hair; the apices of the tarsal joints 

 incline to rufous; on the hind tibiae are eight spines, stomt, all longer 

 than thick and becoming longer towards the apex; they are dark rufous. 

 Cak-aria white. 



.3440 Paratiphia fuscinerva sp. nov. 



Black, not very thickly covered with silvery pubescencea the apices 

 of the clypeus and mandibles are rufous; wings hyaline, the stigma 

 black, the nervures fuscous — almost testaceous, the basal abscissa of the 

 radius shorter than the second. Metanotal area distinctly longer than 

 its width at the base; the apex not separated, transverse; the central 

 keel narrow; the sides near the keel irregularly punctured. Head strong- 

 ly punctured, the ocellar region smooth. Basal half of pronotum closely 

 punctured, the apical smooth. Mesonotum rather strongly punctured, the 

 sides smooth. Scutellum punctured laterally and at the apex, and with 

 two punctures in the middle. Upper half of propleurae punctured, the 

 lower covered with roundly curved striae. Mesopleurae punctured, the 

 metapleurae obliquely striated. Legs thickly covered with white hair; 

 the apices of the tarsi and their spines rufous; the tibiae with seven 

 teeth, the basal short, blunt, indistinct, the last (and outer) much thin- 

 ner than the others and slightly longer than the penultimate. Length -i 

 mm. Ormsby county, Nevada. 



This is a smaller and more slenderly built species than van. 

 punctata; it may be easily separated from it by the metanotal area 

 being narrower and clearly longer than wide.
