NO. 2210. A REVISION OF THE CREMASTINI—CUSHMAN. 507 



scarcely twice as long as wide at base, distinctly wider at apex, it 

 and the postpetiolo longitudinally nigulose; ovipositor about a half 

 longer than fii-st tergito. 



Black; a small spot between insertion of antenna and eye brown; 

 clypeus at apex, mandibles, palpi, and legs (largely) rufo-tcstaceous; 

 antennae black, paler below; hind trochanters, last tarsal joints, and 

 apices of hind tibiae (faintly) infuscated; tergites, 1 to 5, black at 

 base, reddish at apex, third largely reddish, remaining tergites black. 



Male. — Very like female, but with eyes scarcely divergent, malar 

 space slightly wider, ocelli slightly larger, and black color of tergites 

 more extensive. 



Type-locality. — Hanover, New Hampshire. 



Other locality. — Canada. 



TyjJe.— Cat. No. 20251, U.S.N.M. 



Described from one female and one male, the former captured by 

 C. M. Weed and the latter by C. F. Baker. 



Distinct from the other two species in its short ovipositor, short 

 areola, short second tergite, and abdominal coloration. 



PSEUDERIPTERNUS GRACILIPES, new species. 



Female. — Length 10 mm., antennae 7.5 mm., ovipositor 5 mm. 

 Head finely, densely granular; face scarcely elevated in middle, more 

 evenly convex throughout, with minute median tubercle above; 

 malar space about half as long as basal width of mandible; inter- 

 foveal line twice as long as foveo-ocular line; inner line of eye concave 

 for most of its length; postoccllar and ocell-ocular lines equal and 

 about a half longer than diameter of a lateral ocellus. Thorax 

 densely, minutely punctured, mesonotum subpolished; mesopleural 

 suture sharp, foveolate only at its upper extremity; propodcal 

 carinae strong, the areola more than three times as long as petiolar 

 area, all areas granularly punctuate, petiolar with a few short longi- 

 tudinal rugae apically; wings with radial cell obtusely pointed, base 

 of second discoidal cell about two-thirds as long as second recur- 

 rent vein, nervcllus slightly postf ureal and broken slightly below 

 middle; hind legs slender, the femur hardly one-fourth as wide as 

 long; hind basitarsus nearly half as long as tibia, fifth joint nearly as 

 long as third. Abdomen one-third longer than head and thorax 

 united, sculpture granular, subpolished toward apex, postpctiole 

 weakly aciculate; first tergite about two-fifths as wide at apex as 

 long, sides of petiole concavely and of postpetiole convexly arcuate, 

 spiracle at middle, carinae and foveae of petiole strong; second tergito 

 about two and one-half times as long as wide at base, its sides nearly 

 parallel; ovipositor about three times as long as first tergite. 



Black; a small spot between antenna and eye brown; mouth parts, 

 antennae, and legs colored as in hrevicauda except a little darker
