Graphisurus, Lacordaire. 



The Canadian records include G. /asciatus, DeG., and G. tri- 

 anguiifer, Hald., but it is quite likely that the latter reference is incorrect, 

 the species being more essentially southern, and occurring from Missouri 

 and Ohio to the Gulf States. 



Stouter, pubescence of upper surface mostly ochreous. Prothorax 

 pale at sides, this pale area enclosing a few small black spots ; 

 median stripe broad, dark, and in turn enclosing three (2 sub-apical, 

 I sub-basal) ochreous spots. Elytra with ochreous pubescence 

 marked by many very small black spots, esi)ecially towards the 

 sides, scutellar area black, as is also a sub-humeral blotch, a large 

 many-angled,intensely black post-median blotch, not extending quite 

 to the suture, and a sub-apical angulate mark. Tarsi equal in width 



in both sexes. •52-.54 in triangulifer, Hald. 



More elongate, pubesence of upper surface chiefly grayish, except 

 for dark markings, which consist of small, closely-placed spots and 

 blotches. These form a tolerably distinct line on each side of the 

 middle of the prothorax, and usually also an ante-median and 

 post-median irregular elytral fascia. Anterior and middle tarsi of 



male broader than in female. .32-56 in. (Fig. 



3.) f asciatus, DeG. 



G. f asciatus is common in the lake regions, and 

 is said to breed in oak and maple. G. triangulifer 

 was found in the larval state boring under bark of 

 injured hackberry trees (Celt is texana) by Mr. 

 Schwarz. 



Ceratographis, Gahan. 



Here belongs C. biguttata ( Liopus biguttatus, 

 Lee), which is unknown to me. Aside from the 

 generic characters, it is stated to be " elongate, 

 scarcely depressed, testaceous, pubescence brownish. Elytra indistinctly 

 mottled, each with an oblique black band behind the middle." Length, 

 .36 in. 



DORCASCHEMA, Lcc. 



Represented in Canada by D. nigrum, Say, which has been bred 

 from hickory limbs. It is easily recognized by the long antennas, entirely 

 black colour and cylindrical form, the prothorax tubularly narrowed 

 behind the middle, and with rugose disk. The elytral punctures are clear
