AMERICAN COLEOPTERA. 185 



hind angles roundecl; disk very strongly elevated and compressed posteriorly, 

 the anterior declivity lightly furrowed ; a strong lateral oblique impression 

 before the middle, the posterior limiting elevation terminating in a marginal 

 prominence. The antennas are of the usual form, the ninth joint as long as the 

 six ( % ) or five ( £ ) preceding. The fifth ventral segment is subequal to the first 

 and evidently shorter than the second ; the first suture broadly sinuous. In the 

 male the fifth ventral is slightly foveate at middle at the apex, a small promi- 

 nence each side. Length 3.5-6 mm. 



Pacific Coast from Vancouver to Southern California. 



MICROBREGH4 Seidlitz. 

 The above name was proposed by Seidlitz in his Fauna Transyl- 

 vaniea, 1891, for the European Anobium emarginatum Duft., a 

 species with which our foveatus Kirby is apparently identical. 

 Whether Microbregma should be regarded as a subgenus as origi- 

 nally proposed or as a genus, as I have chosen to do, is of course a 

 matter of individual opinion and one to which reference has already 

 been made under Anobium. The characters which separate it from 

 Had rob regimes are briefly as follows : Sides of prothorax straight 

 and parallel, hind angles sharply defined ; third ventral segment 

 nearly twice as long as either the first or fourth ; first and second 

 ventral sutures anteriorly arcuate ; fifth ventral densely granulate 

 posteriorly ; front and middle tibiae acutely produced externally at 

 apex. 



1. M. ("marginatum Duft.— Brown, prothorax not as wide as the elytra, 

 the sides parallel and a little sinuate between the angles which are almost right; 

 the base sinuate within the angles then broadly strongly rounded or lobed ; disk 

 with a very feeble median prominence before the hind margin, anterior to which 

 it is broadly excavated, and on each side tuberculate ; surface sparsely granulate. 

 The antennae are 11-jointed, the ninth joint shorter and more triangular than in 

 Hadrobregmus, being only as long as the three or four preceding joints. The only 

 other characters of importance are mentioned in the preceding generic diagnosis. 

 Length 4-5 mm. 



New Hampshire; Massachusetts; Canada; Michigan; Minne- 

 sota; Colorado; British Columbia. 



This species is not given in either the New Jersey, District of 

 Columbia, Southwestern Pennsylvania or Cincinnati lists, and is 

 evidently confined in America to the northern portion of the conti- 

 nent. It occurs in northern Europe. 



Var. granieollis n. var. — This name is proposed for a form occur- 

 ring in Washington, Oregon (Portland), and California (Lake
