36G THE CANADIAN ENTOMOLOGIST. 



Euura maculata, n. sp. 



Body black, with the head except a quadrangular spot about 

 the ocelli and extending to the eyes, prothorax, margin of the lobes 

 of the mesonotum narrowly, upper half of the pleune, tegula^, legs, 

 abdomen, except above at base, and saw-guides, except at apex, 

 resinous; frontal crest indefinite and apparently wanting; median 

 fovea a minute pit; saw-guides large, upper and lower margins 

 slightly converging, and broadly rounded at apex. Length 7 mm. 



Habitat — Collected by Professor J. S. Hine at Columbus, 

 Ohio, and bears the number 169. 



The form of the frontal crest distinguishes this species from 

 all of the described eastern species. 



Euura minuta, n. sp.

 median fovea indefinite, represented only by a shallow depression 

 in the frontal crest. Length 4 mm. 



Habitat — Ames, Iowa. Professor E. D. Ball, collector. 



This species is related to nigra Prow, from which it is separated 

 by the colour of orbits and to nodus Walsh, from which it is 

 separated by the indefinite median fovea. 



Metallus bethunei, n. sp.

 or less infuscated ; the ocellar furrow adjacent to the median ocellus; 

 the interocellar furrow wanting; depressed area behind the median 

 ocellus broad; median fovea a broad, deep pit; lateral fovea distinct 

 from lateral fovea; body polished with spare setigerous punctures;

 twice as long as broad; front wings with the free part of IVL+Cui 

 joining the cell M4 at middle; the saw-guides straight above, some-
