A distinct and interesting s[)e(;ies. The thorax is often silvery 

 sericeous, and the posterior tibiie sometimes have an obscure wliite

9. — Head black; face very closely and minutely punctulate, with here and 

 there a larger piinctation, shining, silvery sericeous; mandibles black, tipped 

 with rufous, punctate, polished; clypeus sinuate, rather strongly emargiiiate ; 

 second segment of flagelUim clavate; liead above minutely transverse-striolate. 

 behind the eyes elongate, posterior margin prominent, subreflexed. Neck 

 rather short, subfinely and irregularly rugulose. Thorax black; prothorax witli 

 an acute tooth on the lateral angles; dorsum finely and very weakly traiisverse- 

 rugulose, with a few indistinct punctations scattered over it, giving the whole a 

 finely shagreened ajjpearance, with a dull lustre; medially behind the groove 

 the punctures become larger and close; on the sides of the thorax they aie also 

 large and close, subreticulate; the propodeum is reticulate. Wings stained yel- 

 lowish fuscous, but slightly irridescent, without violaceous reflection ; veins 

 and stigma black. Legs black, base of tibite white; posterior coxse finely trans- 

 verse-striolate. Abdomen with a luxurious satiny lustre, petiole black, next two 

 segments rufo-ferrnginous, remaitider black. Length 16 mm. 



I have seen two specimens of this species, and they seem to be 

 sufficiently distinct from F. occidodalis by the shape and posterior 

 margin of the head, the punctation of the thorax and the (!olor of 

 abdomen, in one specimen the only white on the tibite is a ring 

 near the base of the posterior.
