claws a little more elongate and less curved than in the female and barely per- 

 ceptibly sinuate beneath. Length 6.5 to 8 mm. 



Labrador; Ungava Bay; Hudson Bay R. R., Manitoba (Wallis). 

 The identity of this species is based on typical specimens sent to 

 Mr. Sherman by Oberthiir. 



A. arcticus Payk. Fauna Suecica, 1798, p. 201. 



reticulatus Kby. Faun. Bor. Amer. Ins. 1837, p. 71. 

 subfasciatus Lee. Smithson, Misc. Coll. VI (1863-1866), p. 17. 



Narrowly oval, or a little obovate ; above fuscous, head in front, thorax with sides 

 and transverse median fascia (often interrupted at middle) and side margins of 

 elytra, yellow. Elytra rather coarsely and deeply irregularly reticulate in both 

 sexes, the lustre rather dull. The pro- and mesotarsi of the male are strongly 

 incrassate, with very large nearly circular palettes beneath ; the anterior protarsal 

 claw angularly dilated before the base, the posterior one just perceptibly sinuate. 

 The flat, slightly longitudinally concave prosternal process, and the sinuate front 

 angles of the thorax in the female are characteristic. Length 6 to 7.5 mm. 



This species is very abundant in Labrador. It is widely dispersed 

 in northern Europe and Arctic Siberia, and may perhaps occur else- 

 where in Boreal America. 



A. ontarionis new species. 



Size large, oval, outline in profile slightly gibbous, the highest point of the con- 

 vexity being a little in advance of the middle. Head and thorax piceous, the 

 latter with the sides narrowly rufescent; elytra dark brown or brownish piceous 

 with sides diffusely paler; surface very finely irregularly reticulate basomedially, 

 the areolae becoming nearly equal at sides and apex; dorsal series of punctures 

 fine and inconspicuous; minute punctulation wanting. Prosternal process nar- 

 row, angulate in cross section; post-coxal length of metasternum less than half 

 that of the coxal plates; hind tibiae with a row of punctures along the inner 

 margin. Antennae and legs rufous, femora a little darker. Pro- and mesotarsi 

 of male widely dilated, glandular hairs with moderate oval palettes; protarsal 

 claws elongate and similarly sinuate beneath. Length 10 to 10.2 mm. 



Bellville, Ontario (type) ; Makinak, Manitoba. 



Described from three examples, all males, submitted by Mr. Sherman. 

 Type in my own collection. 



This is one of our largest species. In. general aspect it resembles 

 erythropterus, but is larger, very much more finely reticulate and with 

 different male claws. 



A. ajax new species. 



Broadly oval, testaceous or brownish testaceous; head, prothorax and body be- 

 neath usually somewhat more rufous; head darker posteriorly, disk of prothorax 

 with rather vague transverse median darker fascia. Antennae testaceous with at 

 most the tips lightly infuscate; terminal joints of palpi infuscate apically. Head 

 and thorax moderately irregularly reticulate ; elytra strongly minutely reticulate, 

 the meshes nearly equal ; minute punctulation lacking ; the usual coarser irregular 

 serial punctures not very well defined. Prosternal process small, acutely com-
