THE CANADIAN ENTOMOLOGIST 191 



in samples of bulbs purchased shows that it has to be dealt with 

 just as much as the larger maggot." 



MacDougalF describes the larva of Eumerns strigatus as 

 measuring "half an inch and over when full grown. It is greyish 

 yellow in colour and has a distinctly wrinkled appearance. The 

 mouth hooks are brown and the respiratory processes at the front 

 end are brownish-red. The rounded hind end is brown at the tip 

 and has a projection on each side with a process which ends in 

 the breathing pores between the projections." 



TWO NEW SAWFLIES (HYMEN.). 



BY E. P. FELT, ALBANY, N. Y. 



The peculiar Xylids with the remarkably developed third 

 antennal segment, are comparatively rare and unusually interest- 

 ing. It, therefore, seems desirable to publish the description of a 

 recently discovered species in this group, and also one of a related 

 Pamphilid. 



Pleroneura borealis, n. sp. The sawflies described herein 

 were collected at Lake Clear, N. Y., June 7, 1907, and in the key 

 given by Rohwer, would run to P. fulvicornis Roh., a larger Cali- 

 fornian species exhibiting some differences in colour from this 

 species. 



Male. — Length 4 mm. Anterior margin of clypeus broadly 

 rounded; narrow, deep furrows extend from the base of the 

 antenna? and unite above the median ocellus, median fovea?, forked 

 ventrally, extending to the base of the ocellus; terminal anterior 

 segment shorter than the preceding. Head and thorax opaque 

 with close, fine punctures; maxillary palpae large, probably 7- 

 jointed, the second segment distinctly shorter than the anterior 

 femora, the first joint about one-half as long as the second. Claws 

 with a minute tooth basally. Hypopygium roundly truncate, 

 first recurrent vein free from the first transverse cubital. Head 

 black. Thorax brownish black. Abdomen reddish brown. The 

 antennae, clypeus, labrum, tegulae, the dorsum of the abdomen
