 species was taken by the useful, worthy and honest Esquimaux Ooligbuk, 

 1 trust I may be excused for giving to it his name. [Previously described

 p. 554. —He gives the State of Maine as its habitat; it was taken on 

 the north shore of Lake Superior by Agassiz's Expedition, and is now

Body black, underneath banded and clouded v.ith paie chestnut. 

 Head smooth; nose, upperlip, and palpi, reddish-yellow; the latter with 

 the la.st joint dusky ; between the eyes is an obscure, roundish, red spot ; 

 prothorax smooth, except an anterior transverse series of punctures which 

 does not reach tiie sides ; as in the preceding specie?; it is surrounded 

 by a broad reddish-yellow marten: sculpture of the elytra like that of 

 D. Ooligbukii^ etc., but not so grossly punctured at the apex ; side 

 reddish-yellow,, the yellow stripe terminating in a fork or tv.-o branches, 

 the upper one not consisting of dots as in D. Margina/is, etc., but entire

 and the base of the abdomen is of the same colour; amis and thighs, 

 pale chestnut, tibiae and tarsi of the four posterio" legs black : the lobes 

 of the metasternum are remarkably obtuse. I have named this insect 

 after a very eminent American Entomologist, Dr. T. W. Harris, who well 

 merits such distinction. [One of our commonest Canadian species of

 in my cabinet flew in at an open window attracted by light, July i, 1864.
