above. Wings byjiline, the iieivures and stigma yellowish, the discoidal 

 uervures entirely wautiug; costal cell very wide; stigma semicircular, 

 the marginal cell as long as the stigma. Inner spur of posterior tibiie 

 fully two-thirds the length of the basal tarsal joint. Abdomen black, 

 l)olished, as long as the thorax, the ovipositor long, nearly half the 

 length of the abdomen. Antenme rather short, brownish-yellow, paler 

 beneath and toward base, filiform, the first and second funiclar joints 

 equal, the following shorter. 

 Habitat. — Ottawa, Canada. 



Specimens are in my collection, received from Mr. W. II. Harrington. 



The species is quite distinct from all others in our fauna in the size 

 of the marginal cell and the long tibial spur of posterior legs. It seems 

 to agree quite closely with the European P. calcar Haliday. c 



Proctotrypes clypeatus, sj). uov. 



9 . Length, 3.5""', to the tip of ovipositer 4.r>'""'. Tolished black ; 

 clypeus and mandibles i)ale rufous; legs, including coxa?, yellowish; 

 ovipositor longer than the abdomen, the basal two thirds reddish yel- 

 low. Antennje pale brownish-yellow, not longer than the thorax, the 

 first flagellar joint a little longer than the second, joints 2 and 3 about 

 equal, fourth slightly shorter, the following to the last about twice as 

 long as thick, the last one-half longer than the penultimate, ovate. 

 Metathorax rugose, with two smooth areas at base above. Wings hya- 

 line, the discoidal nervures wanting; stigma large, brown-black; mar- 

 ginal cell less than one-half the length of the stigma. Tibial spurs of 

 posterior legs about one-half the length of the basal tarsal joint. Ab- 

 domen polished black, about as long as the thorax, the petiole scarcely 

 apparent, second segment at extreme base with a long foveola on 

 either side. 



Habitat. — Ithaca, N. Y. 



Type in Coll. Ashmead. 



Described from a single specimen received from Mr. F. H. Chitten- 

 den, who informs me he reared it October 15, 1884, from a large yel- 

 low, rather woody, fast-growing tree fungus, from which Melandryid, 

 Mycetophagid, Staphylinid and Scaphidiid beetles were obtained.

9 . Length, 2.5 to 3""". Polished black ; mandibles black or piceous ; 

 legs reddish yellow, the coxje sometimes black or black toward base ; 

 ovipositor about ^ the length of the abdomen or very slightly longer 

 than the basal joint of hind tarsi. Antennae brown, not longer than 

 the thorax, slightly thickened toward base, the basal joint or some- 

 times the 3 or 4 basal joints, yellow; first flagellar joint about one-half 

 longer than the second, or the second joint is two-thii'ds the length of
