316 THE CANADIAN ENTOMOLOGIST. 



Prof. Cockerell's characterization of this form is quoted to aid in 

 identifying the species. 



"(b). Race angustior, ^. — Face conspicuously longer than broad j 

 sides of clypeal yellow above, squarely notched, distance between the 

 yellow and eyes extremely small, pubescence somewhat paler. 9 smaller, 

 with pale pubescence, abdomen with the white bands on the fourth and 

 fifth (instead of third and fourth) segments, that on the fifth fuscous in the 

 middle, but brilliant white at tiie sides. Wings clearer."

Prof. Cockerell designated this as a race, but since it is found in th.e 

 same locality with the typical form it can rank only as a variety or form. 

 The description is as folluws : 



" (a). Race lattor, (^ . — Facial quadrangle not far from square; sides 

 of the clypeal yellow, gradually sloping above, distance between the yellow 

 and the eyes quite considerable."

$ 14 mm. Head dullish, sculpture of the face, cheeks and occipul 

 nearly or entirely hidden by rather long pale ochraceous pubescence ; 

 greater part of head finely roughened; clypeus with coarse shallow adjoin- 

 ing punctures ; labrum apparently rugulose, the sculpture obscured by 

 pubescence, the ocelli forming a low triangle nearly on the supraorbitat 

 line (/. ^ , an imaginary line connecting the upper posterior margin of the 

 eyes), the posterior ocelli as far from each other as the lateral ocellus is 

 from the nearest eye margin; first joint of the flagellum a trifle shorter than 

 the next two joints together, apical joint of antennoe as broad throughout 

 as the preceding joint, the apex obHquely flattened beneath ; mandibles 

 slightly emarginate at tip, the emargination making two very short sub- 

 equal teeth, the outermost tooth being longest.
