THE CANADIAN ENTOMOLOGIST. 77 



SIX NEW OTTAWA PROC TOTRYPID./E. 



BY W. HAGUE HARRINGTON, F. R. S. C, OTTAWA. 



The following descriptions of species which appear to be additions 

 to our fauna were prepared more than a year ago, but were withheld in 

 the hope that more material might be obtained last season. That hope 

 was, however, not fulfilled ; largely, perhaps, be it confessed, through 

 lack of sufficient perseverance on the part of the writer in collecting : 



1. Lygocerus pallipes, n. sp. 



$ . — Length 15-2 mm. Black, finely punctulate and sparsely pubes- 

 cent. Mandibles and palpi yellowish ; antennae black, except the scape 

 at base and beneath ; scape stout, first joint of flagellum about half as 

 long as scape, second as long as pedicel, remaining joints subequal. 

 Legs, including cox?e, yellow. Wings subhyaline, stigma large, yellow. 

 Abdomen stout, pointed at tip. 



^ . — Antennae with joints three to seven dentate; joints eight and 

 nine broadened, two terminal joints slender. 



Described from two females and one male captured near Hull, Que., 

 on 2nd, 7th and 14th August, 1897. 



2. Ceraphron crassicornis, n. sp. 



$ . — Length 2 mm. Honey-yellow, finely pubescent and closely 

 finely punctate. Head large, transverse ; face not deeply excavated ; 

 vertex with impressed line ; ocelli black, in very small triangle ; antennae 

 much incrassated, black, except base of scape, which is honey-yellow ; 

 scape stout, reaching above ocelli, tapering from base to about middle ; 

 pedicel short, first joint of flagellum twice as long and much stouter, 

 second joint less than one-half as long as first, joints three to seven sub- 

 equal, slightly larger than thick, last obconic not much larger than pre- 

 ceding. Thorax with distinct median furrov/ j the sutures at base of 

 scutellum with large punctures ; posterior margin of scutellum and the 

 postscutellum black, the latter with a strong truncated spine ; pleura 

 transversely striated. Legs rather siout, entirely honey-yellow. Wings 

 narrow, abbreviated, reaching only to middle of first abdominal segment. 

 Abdomen stout, acuminate at tip, which is brownish dorsally ; first seg- 

 ment with deep and long striae, black on anterior margin. 



This is a large and very distinct species, of which only one female 

 has as yet been taken.
