Thorax red with discoidal dark stripe (.35-. 40 in.) . . .gracilis, Newm. 



Thorax entirely greenish-black v. inoi-nata, Rand. 



We give figures of L. Mozardi in all stages (Fig. 58) 

 and the beetle of L. gracilis (Fig. 59). I have a specimen 

 of L. convexicollis, Horn, with the label " B. C." It may 

 be known from L. Mozardi by the larger size (.47 in.) 

 and the entirely black under surface. 



Dacne, Latr. 



A small, black insect {Dacne 4-rnaculata. Say,) .12 in. 

 long, the clypeus and a himieral and apical spot on each 

 fig- 59. elytron reddish or yellowish, represents this genus. At 

 times the apical spots may extend over the entire tip of the elytra. 



Megalodacne, Crotch. 

 Two very fine species of this genus are found in Canada. They are 

 large insects with black thorax, the elytra banded with black and orange- 

 red in a manner recalling certain carrion beetles {Necrophoriis), and are 

 found in fungi. The two Canadian species resemble 

 each other very closely, differing thus : —  



Smaller ( 50-. 60 in.). Elytra finely 

 seriately punctate, thorax shorter... 



./asciata, Fabr- 



Larger (.64-80 in.). Elytra not punc- 

 tate (Fig. 60) heros, Say. 



IscHVRUS, Lac. 



/. qiiadr ipjinct at us, OXw. (Fig. 61), 

 is about .30 in. long, black beneath, 

 the side margins of thorax and abdo- 

 men marked with yellow or reddish. Above it is fulvous, the head 

 black, the thorax with a series of four transverse spots across the middle, 

 the elytra with black bands and spots as shown in the figure. 



Mycotretus, Lac. 

 Small red and black insects found on fungi or dead wood. Two 

 species with one varietal form occur here and may be known thus : — 

 Thorax black,scutellum and elytra red (.16-. 18 \n.).sa?igui?iipen7iis, Say. 

 Thorax and scutellura black, elytra bicolored. 



Apical third of elytra obliquely black. (. 14 to .16 \x\.)..pulchra, Say. 

 Black mark on elytra, angulate anteriorly v. dimidiata, Lac.
