ROLAND IIAYWARD. 29 



It is knowu to me i'roni Labrador, Xewfouiidlaud, the ^lairdulen 

 Islands, AVinnipeg, Manitoba, Slave Lake, Hudson Bay and from 

 altitudes of 8,000-10,000 feet in the Rocky Mountains of Colorado. 



12. A. hudwoiiica n. sp. — Nearly parallel, elongate, feebly convex. I'ioeous 

 or nearly blaek, feebly feueoua, the elytra very finely aliitaceous. Head srareely 

 narrower than the thorax at apex ; frontal grooves short, not extending ffirward 

 on to the epistoma ; antennae slender, nearly as long as the head and thorax, rufo- 

 testaceous; palpi rufotestaeeons. Prothorax subquadrate, about one-half wider 

 than long, as wide at base as apex, with a few scattered punctures each side at 

 apex, distinctly punctate at base; apex slightly emarginate; sides arcuate, dis- 

 tinctly but not strongly sinuate in front of base, which is nearly truncate; ante- 

 rior transverse impression distinct, the posterior nearly obsolete; median line 

 abbreviated in front; basal impressions deep, punctate, very distinctly bifoveate, 

 the inner fovea longer tlian the outer; liiud angles rectangular, obtusely cari- 

 nate. Elytra together not wider than the thorax and about twice as long as 

 wide, flattened on the disk, striate; humeri rounded; stria' entire, punctate 

 nearly to apex, the scutellar stria moderately long, the eightli with llie row of 

 ocellate punctures broadly interrupted at middle; intervals flat. Body beneath 

 piceous, sides of metasternum and meso- and metasternal episterna sparsely 

 punctate. Legs rufous; middle and jjosterior femora with two setigerous punc- 

 tures along the inner margin ; hind tarsi with the two basal joints feebly grooved 

 on the outer side. Length .3.3-. 35 inch ; 8.25-8.75 mm. 



In the males the teeth of the middle tibise are much nearer the 

 apex than usual, the upper being situated about two-thirds from 

 the base, the lower about midway between it and the apex. 



The form somewhat recalls that of rtifanana, but the hind angles 

 of the thorax are obtusely carinate, the posterior tarsi grooved ex- 

 ternally and the size smaller, while the position of the teeth of the 

 middle tibite is also different. 



Described from three males from Ungava Bay, Hudson Bay 

 Territory (Collection U. S. National Museum). 



13. A. es<*li«««"lioltzi C'haud. — Nearly oblong, moderately elongate, slightly

 males, aliitaceous in the females. Head nearly as wide as tlie thorax at aj)ex ; 

 frontal grooves short, deep, not prolonged on to the epistoma; antennae slender, 

 shorter than the head and thorax, the first two joints rufous, tlie outer ones 

 darker; palpi rufous. Prothorax about one-half wider than long, as wide at base 

 as apex, subquadrate, punctate at base and ai)ex ; apex slightly emarginate, the 

 anterior angles rounded; transverse impressions feeble; median line distinct, 

 abln-eviated in front; basal impressions broad, deep, bifoveate, the foveae slightly 

 oblique, the inner longer than the outer; base truncate; sides with the margin
