White-horned Urocerus 



Urocci'iis albicornis Fabr. 



A conspicuous, bluish black horntail about 1% inches in length may be observed 

 upon spruce, or its thick, fleshy larvae may be found at work in the wood. 



This species is a close ally to the common pigeon tremex so frequently 

 observed on diseased or dying maples and elms, and has similar habits. 



Description. The adult may be easily recognized on account of its 



resemblance to the pigeon tremex, p. 61, in connection with the following 



description by Dr Harris : 



The white-horned Urocerus has white antennae, longer and more 

 tapering than those of the pigeon tremex, and black at each end. The 

 female is of a deep blue black color, with an oval white spot behind each 

 eye, and another on each side of the hinder part of the abdomen. The 

 horn on the tail is long, and shaped like the head of a lance. The wings 

 are smoky brown, and semitransparent. The legs are black, with white 

 joints. The body measures about an inch in length, and the wings expand 

 nearly two inches.
