NO. 2210. A REVISION OF THE CREMASTINI—CVSJIMAN. 545 



and clypeus at sides yellow; and the propodoum more strongly con- 

 vex, with the areola relatively longer and narrower, and not reaching 

 so far over the coxae. The eyes are slightly divergent helow, al)ou't 

 as long as width of face. The ocell-ocular Imo is about half as long 

 as postocellar line and the ocelli slightly less in diameter than the 

 former, unusually small ocelU for a male of this genus. 



CREMASTUS (ZALEPTOPYGUS) BILINEATUS, new species. 



Female. — Length 9 mm., antennae 5.5 mm., ovipositor 7 mm 

 Head sparsely, weakly punctate, more densely on face, more than 

 twice as wide as long, temples weakly rounded; eyes parallel, shorter 

 than width of face; face elevated medially; malar space about as 

 long as basal width of mandible; clypeus as long as foveo-ocular lino, 

 which is about two-thirds as long as interfoveal hne; mandibles pro- 

 truding. Thorax rather stout, propodeum strongly rounded and 

 extending only a short distance over coxae; upper hind angle of 

 pronotum punctate, rest subpolished; mesoscutum finely punc- 

 tate, notauh weak; scutellum laterally carinate, flattened, punctate; 

 pleura and sternum finely punctate, mesopleura polished above, 

 sternauli weak; areola about two-thirds as long as petiolar area, elon- 

 gate pentagonal; petiolar area but little wider than areola, weakly 

 rugulose; other areas weakly punctate, except basal areas, which are 

 smooth; stigma half as long as wide, radius at apical third; second 

 recurrent interstitial; second abscissa of radius curving outward to 

 near apex then forward to costa; second discoidal cell a third as wide 

 at base as at apex; legs slender, hind basitarsus little more than half 

 as long as tibia and about as long as next tliree joints united. Abdo- 

 men twice as long as head and thorax, slender, rather strongly com- 

 pressed beyond third tergite, tergites 1 and 2 together shorter than 

 remainder of abdomen; first tergite distinctly longer than second, 

 petiole with carinae obsolete toward base, ventral edges of tergite 

 curving toward each other below and partly covering the tergite, 

 postpetiole elevated above level of petiole, nearly three times as 

 broad as narrowest part of petiole; second tergite nearly four times 

 as long as basal width, much wider at apex, striate; ovipositor 

 slightly longer than abdomen. 



Black with tergites beyond second largely redtlish; head black 

 with orbits broadly and completely, cheeks, clypeus, and mandibles 

 yellow; antennae black, scape and pedicel piceous below; thorax 

 black, notauli, scutellum, tegidae, and wing bases yellow; wings hya- 

 line, veins and stigma brown, latter pale at base; all coxae whitish 

 at apex and above, the amount of white increasing toward the front, 

 black at extreme base, especially hind coxae, otherwise testaceous; 

 front and middle trochanters and front femora whitish in front, other- 

 wise front and middle legs testaceous; both joints of liind Irochantor
