64 THE CANADIAN ENTOMOLOGIST. 



Tremex columba, Linn. In July, 1891, Mr. John Stewart, of this 

 city, informed me that he had a stick of firewood containing a great many 

 larvae of beetles. Some days later I called on him to examine it and 

 found that the insects had commenced to emerge, and that they were the 

 common Horntail. The log was gnarlly rock-maple, about 10 inches in 

 diameter, partly decayed, but still very hard, as was proved in sawing 

 out a section, which I took home. I secured a number of larvae and 

 pupa?, and from the section retained numerous flies emerged, of which 

 only one was a male. On leaving for Japan (July 22nd) I iocked the 

 block up in an old cabinet, and on my return found that several more 

 females had appeared, and of course died during my absence. The fact 

 of most interest concerning these is that one had endeavored to deposit 

 in the block, and had died with the ovipositor deeply inserted. 



NEW CHERNETID^ FROM THE UNITED STATES. 



BY NATHAN BANKS, SEA CLIFF, N. Y. 



Since my last article on this group (Can. Ent , Aug., 1891), I have 

 obtained quite a number of forms ; some of the new ones are described in 

 this article. Two genera, new to the U. S., are recorded, both of which 

 occur in South America. Chelifer alius, described by Leidy in Proc. 

 Phil. Acad. Sci., 1877, agrees, as far as description goes, with Chelanops 

 oblongus, Say, and with no other form known to me, therefore I consider 

 it a synonym of C. oblo7igus. 



Chelanops pallipes, n. sp. 



Length, 3 mm. Colour: cephalothorax, dark brown ; palpi, red-brown ; 

 dorsal scuta?, yellow-brown ; legs, yellow-brown. General appearance of 

 C. acuminatus, but the hand is not black as in that species. Structure 

 also similar to C. acuminatus, differs in being furnished with clavate 

 hairs ; the trochanter does not project/as much behind ; the femur is more 

 slender ; the tibia is not nearly as much gibbose on the inner side ; the 

 hand less broad and shorter ; the fingers much more slender, about as 

 long as the hand. 



California. A few specimens. 



Chelanops latus, n. sp. 



Length, 3.2 mm. Cephalothorax and palpi red-brown, the fingers 

 black, scuta? red-brown, legs brownish-yellow. Structure similar to C.
