This insect by the markings suggests E. subrotundus Casey, but 

 the great difference in size and the peculiar form of the claws seem to 

 indicate an undescribed species. 



Brumus septentrionis Weise. 



Broadly oval, convex, elytra explanate, shining ; body black above and beneath, 

 elytra orange-yellow with very variable black markings. Tibiae and claws entirely 

 simple in both sexes. Punctuation minute and sparse. The male is to be distin- 

 guished only by the truncate fifth segment and additional sixth segment. 



This species varies greatly in its markings as follows : 



Var. septentrionis Weise. 



Elytra yellow, each with narrow sutural black stripe connected with small apical 

 black space and two small black discal dots. Hogei is included as an absolute 

 synonym. 



Length. — 3.5 to 4.5 mm. = . 14 to . 18 inch. 



Habitat. — Manitoba, Montana, Washington, Colorado, Utah, N. Mex., Ariz., 

 El Paso, Texas. 



Var. nevadensis, new variety. 



Elytra yellow, each with broad black sutural stripe connected with broad black 

 apical space. No discal black dots in the type but in specimens collected with it one 

 or two small dots appear. 



Length. — 2.5 to 4.0 mm. = .10 to .16 inch. 



Habitat. — Reno, Nevada, collected by Professor Wickham, July 18. 



This is the only form thus far known from the coniferous forests of 

 the Sierra but it is possible that further collecting may disclose other 

 interesting forms from that region. 



Var. ovoideus Casey. 



Elytra yellow with broad sutural black stripe connected with black apical space 

 and two large discal black spots. The anterior spot is connected with the sutural 

 stripe in front, while the posterior spot is connected with the black apical space. 

 In some specirrens these black markings become so extended as to leave only basal 

 and lateral margin and subapical dot pale ; the resulting form so closely resembles E. 

 californicus in its markings as to require an examination of the claws for its identi- 

 fication. 



Length. — 3.8 to 4.0 mm. = .15 to . 16 inch. 



Habitat. — Colorado, Arizona. 



Var. davisi, new variety. 



Elytra yellow with broad black sutural stripe connected with broad black apical 

 space and two large black discal spots connected with the sutural stripe in the type 

 but disconnected in other specimens which I associate with it. The spots appear to 

 be all connected in the more northern specimens. 



Length. — 4.0 to 5.0 mm. =.16 to .20 inch. 



Habitat. — Lake Superior, Mich., Mass., N. J., Pa., D. C, Va., Ala.
