niann, and tliose who follow his system. As a division of any rank 

 it is now dropped hy all students, and considered merely a group of 

 Celia. In fact, it is not easy to separate it from the musculus group, 

 as the nientum tooth is by no means easy to see at all times. 

 The only species is 



A. bruniiea Gyll. — Piceous or brown, with faint bronze lustre, obloug. 

 parallel. Head smooth, anteuiife entirely pale. Thorax about one-third wider 

 at base than lonji. slightly narrowed in front, sides feebly arcuate, hind angles 

 rectangular, apex slightly emarginate, disc moderately convex, smooth, coarsely 

 punctured along the base and with two basal depressions, the outer deeper and 

 limited externally by an obtuse carina. Elytra striate, strise finely and distantly 

 punctured, intervals slightly convex. Body beneath smooth and shining; legs 

 rufo-testaceous. Length .24 — .28 inch.; 6 — 7 mm. 



In this species the scutellar stria is moderately long, but usually 

 free at tip. The form is rather more parallel than in any of our 

 Celia. 



Botb sexes are equally shining. The male has one and the female 

 two anal setfe each side. 



Occurs from Alaska southward to Washington, and also to Colo- 

 rado. It is not rare in northern Europe.
