THE CANADIAN ENTOMOLOGIST. 153 



, 



Larger, pronotum compressed, prominent along the middle, basal 

 elevation of elytra strong. Third antennal joint strongly spinose. 

 .24-.40 in verrucosus, Oliv. 



Smaller, less convex, pronotum not compressed, basal elevation of 

 elytra feeble, third antennal joint briefly spinoso - dentate within 

 at apex. .24 in insinuans, Cas. 



These bear considerable resemblance in form to Euderces, but 

 are without the ivory-like band of the elytra. In colour the former is 

 blackish ; legs, in part, and basal three-fifths of elytra sometimes rufous, 

 pubescence white or cinereous, arranged anteriorly in narrow oblique 

 bands which follow the course of the basal elytral gibbosities. Behind 

 these oblique bands is a very narrow cinereous one, nearly transverse in 

 direction. Tip broadly covered with cinereous pubescence. I have not 

 seen C. insinuafis, which is described from a single male. Wild cherry 

 is known to be a food-plant of C. verrucosus. 



MiCROCLYTUS, Lee. 



M. gazellula, Hald., is found in the adult state on oaks. The genus 

 differs from Cyrtophorus in not having the third antennal joint spinose at 

 tip.* It is " a small insect, piceous or reddish-brown with the thorax 

 above and the elytra, except about the middle of the suture, black and 

 rather closely punctured, the legs and antennae always paler. Elytral 

 markings composed of long white hairs arranged as follows : An oblique 

 line from the scutellum, a very short transverse or slightly arcuate line 

 about the middle entirely distinct from the next, a broader band 

 immediately behind and nearly transverse, a blotch covering the entire 

 apical eighth of the length of the elytra." (Leng.) In the male the 

 antennae equal, in the female reach two-thirds the length of the body. In 

 the former sex the elytral tips are very slightly truncate, in the latter 

 separately rounded. 



*Since publication of the table of genera I have come across the following note by 

 Dr. Hamilton (Can. Ent., XXIII., p. 63) : — "The characters separating Cyrtophorus 

 and Alii roclyt IIS were originally feeble, and have recently become more so by some one 

 discovering that the relative lengths of the antennal joints in the male of the latter are 

 the same as in the former, thus leaving in the males only the presence or absence of a 

 small spine at the end of the third joint of the antenna? as diagnostic," By a clerical 

 error the legend Ci'rambycoides is [jlaced one line too high up on p. S6 of my table ; it 

 should be on line 2, and embraces all the genera from Chioii to Microtlytiis, inclusive.
