9. METEORUS POLITUS (Provancher). 



Perilitus politua Provancher, Addit. faun. Canad. Ilymen., 1886, p. 126. 

 Meteorus politus Provancher, Cresson, Synops. Hymen. N. Amer., 1887, p. 229. 



Type. — In the Museum of Public Instruction in Quebec, Canada. 



Distinguished at once by the somewhat infumated wings and the 

 unusually long petiole of the first discoidal cell. Usually the thorax 

 is black, and the abdomen practically entirely reddish, although the 

 latter is sometimes more or less blackish at base or apex; antennae of 

 the female specimens I have seen have 25 segments, with the apical 

 segment unusually large; the male antennae have 29 to 30 segments; 

 radial cell narrow and short; nervulus interstitial with basal vein, or 

 nearly; the nervellus is shorter than lower abscissa of basella, which is 

 usually subequal with upper abscissa or a little shorter; first tergite 

 rather coarsely striate, the ventral margins widely separated. 



Distribution. — Canada; northeastern United States. 



Host. — Unknown. 



The National Collection has a homotype labeled as such by Mr. 

 Gahan; this specimen has no locality label, but it is a Harrington 

 specimen, and is probably from Ottawa. There is one other specimen, 

 from Ottawa, Canada, in the United States National Museum. In the 

 Cornell University collection there is a female of this species, from 

 Coniston, Ontario; and in Doctor Brues's collection there are several 

 specimens from Truro, Nova Scotia; and Petersham, and Barnstable, 

 Massachusetts.

I have seen no specimens of this species; but have given it its place 

 in the key on the basis of the original description and notes made by 

 Mr. Gahan upon an examination of the type. It has been placed with 

 politus, angustipennis, and fumipennis because Provancher mentioned 

 slightly infumated wings. It is evidently an exceedingly small 

 species. Following are Mr. Gahan's notes in part: 



This is the smallest species known to me. Petiole apparently has very indistinct 

 fossae above. Head full beliind eyes; ocelli A'ery small, postocellar line shorter than 

 ocell-ocular line; antennae broken; first flagellar segment fully three times as long as 

 thick, longer than scape and pedicel combined, and about equal to second flagellar 

 segment; malar space less than base of mandible; face shining, faintly rugulose, vertex 

 polished; mesonotum polished, the parapsidal grooves defined and faintly crenulate; 

 propodeum with a median carina, two sublateral and two transverse carinae, one near
