THE CANADIAN ENTOMOLOGIST. 



A. Elytra with a light spot before the middle of each. 



Elytral spot nearly circular, well defined, surface densely punc- 

 tate (,io-.i55 in.) bigiittatus, Say. 



Elytral spot ill-defined, irregular, surface lightly punctured (.10 



_ I 2 in.) fasciatus, Melsh . 



AA. Elytra uniformly ferruginous or testaceous or slightly darker at 

 tip, not spotted. 

 Body flattened above. 



Second antennal joint shorter than third (.07-09 in.) 



modestus, Say. 



Second antennal joint equal to third (.05-08 \n.)..tcstaceus, Fabr. 

 Body convex. 



Anterior thoracic angles toothed (.08-. 10 \n.)..co}ivexulus, Lee. 

 Anterior angles rounded (.056-.08 in.) adustus, Lee. 



Dendrophagus, Schonh. 



D. glaber, Lee. (Fig. 3), is a shining, nearly black 

 species (the elytra sometimes brown), varying from about 

 .25 to .28 in. in length, of depressed elongate form, the 

 head and thorax with deep coarse punctures, the wider 

 elytra being punctate-striate. The antennte are long, 

 the first joint about equal in length to the head. 



Brontes, Fabr. 



Body very flat, closely and coarsely 

 punctured, antennas nearly or quite as long 

 as the entire body, the first joint about 

 equal to the next three. The sides of the 

 thorax are minutely serrate and sinuate. But one species 

 {B. diibhis, Fabr., Fig. 4) is actually recorded from Canada, 

 but as another is probably common there, I give Capt. 

 Casey's table for their distinction : — 



Elytra of male angulate posteriorly, head and thorax 

 paler (.19-23 in.) dubius, Fabr.' 



Elytra evenly rounded behind in both sexes, body 

 above unicolorous (.19-. 21 in.) debilis, Lee.
