120 NORTH AMERICAN NYSSONIDAE (hYMENOPTERa) 



fifth and sixth dorsal segments, four anterior eoxae in front, hind coxae except 

 at base, four anterior trochanters except behind, hind trochanters at tip in 

 front, four anterior femora except basal line above, hind femora except hne 

 above, four anterior tibiae except apical spot behind, hind tibiae except line 

 behind, narrowed basally, front tarsi, middle metatarsi and hind metatarsi 

 beneath; the following are ferruginous, flagellum beneath, apical segments of 

 middle tarsi, and posterior tarsi except basal segment beneath. More or 

 less shining, slightly punctate species, with inconspicuous pile. Wings 

 stained brown, most deeply so in the region of the marginal cell; stigma and 

 costa ferruginous. Length, 9 mm. 



Eyes not emarginate, convergent below but tlie face not strongly narrowed; 

 clypeus broad, convex, its margin broadly and shallowly emarginate, its 

 surface and that of front with minute punctulation and sparse larger but 

 small and inconsi)icuous punctures. Antennae long and slender, the third 

 segment as long as the distance between the ocelli, the ninth widened beneath 

 at apex, the tenth, eleventh, twelfth and thirteenth with inferior cicatrices, 

 the twelfth with an acute inferior tooth. 



Mesonotum with sjiarse inconspicuous punctures, scutcllum and meso- 

 pleura polished and with few punctures; epicnemial areas rounding into the 

 mesopleura and mesosternum, separated from the former by a carina which 

 curves backward sei)arating the mesopleura from the mesosternum. Tri- 

 angular area of ])ropodeum striate, posterior surface with a median longi- 

 tudinal rugulose sulcus, area covered by yellow spots smooth and almost 

 impunctate, cephalad of this, on sides, an oblique rugulose fiuTOW, cephalad 

 of which the surface is polished and impunctate. 



Anterior femora widened medially. 



First segment of the abdomen, while not ]:)etiolate, is slender, only slightly 

 widened posteriorly; sixth dorsal .segment short, broadly and obtusely rounded 

 at apex, ex[)osing the seventh, not at all coarsely punctate; the second ventral 

 not prominent, the seventh ventral projecting as a deeply bifid process, the 

 tynes acute; surface of the basal dorsal segments polished and impunctate, 

 the apical segments and the ventral sparsely and shallowly punctate. 



Habitat. — California: Claremont, one male, (C. F, Baker). 



Type. — Cornell University no. 144.1. 



This species is closely related only to mirandus and to lamin- 

 iferus. The anterior femora of laminifenis have an enormous 

 lamina beneath, in viirandus a deep fossa filled with white hairs; 

 while the front femora of femoratus are swollen, they are much 

 less so, and without a fossa beneath. In color, shape and sculp- 

 ture femoratus resembles mirandus.
