98 THE CANADIAN ENTOMOLOGIST. 



CANADIAN HYMENOPTERA.— No. i. 



BY W. HAGUE HARRINGTON, OTTAWA. 



Under this heading, I propose to give from time to time descriptions 

 of new species in my collection, and such notes on other species as may 

 seem of value to students of our fauna. 



NoTOPYGUS AMERICANA, n. sp. — Female, length lo mm. ; head, 

 antennfB, thorax, coxsb and first segment of abdomen, black ; remainder of 

 abdomen and legs red ; antennae as long as head and thorax, filiform, 

 joints short and subequal ; thorax elongate, shining ; metathorax, rounded 

 and obliquely truncate ; wings, slightly infumated, with black nervures ; 

 abdomen shining, as long as thorax, triangularly clavate, truncate at apex, 

 with the ovipositor curved upward ; sheaths black. 



Described from one ? captured on i6th June, 1891. This fine 

 species is the first of the genus to be recorded from Canada, and may be 

 readily recognized by the conspicuous, erect ovipositor. 



Prionopoda CANADENSIS, n. sp. — Female, length 9 mm.; head above 

 antennae, thorax, coxae and trochanters, posterior tibiae and tarsi, base 

 and apex of abdomen, black ; face below antennae, the cheeks, anterior 

 and middle legs, posterior femora and base of tibiae, abdominal segments 

 two, three and base of four, and venter, red ; head very large, wider than 

 the thorax, cheeks much swollen ; antennae very long, brownish above, 

 pale beneath ; third joint globose, smaller than second, fourth nearly as 

 long as five and six ; thorax short and robust ; metathorax rounded ; 

 scutellum rather prominent, rounded ; wing without areolet ; posterior 

 legs long, femora slightly clavate, coxae large, globose ; claws strongly 

 pectinate ; abdomen fusiform, somewhat compressed at apex. 



Described from one $ captured on 20th June, 1891. This is a very 

 handsome species, owing to its coloration and highly polished appearance 

 (no punctures are visible under a strong hand lens). It should perhaps 

 form the type of a new genus, as it differs greatly in structure of thorax, 

 etc., and in wing venation from P. scutellata, Ashm. 



IscHYROCNEMis oTTAWAENSis, n. sp. — Female, length 7 mm.; black 

 with the legs, scutellum, mouth parts and orbits of eyes honey-yellow ; 

 head slightly swollen so that the face is feebly carinate ; antennae long, 

 pubescent, with longer erect hairs at apices of joints ; thorax shining ;
