knowledge his indebtedness to the authorities of the Museum of 
Comparative Zoology at Cambridge for the opportunity of 
examining specimens of all the European species mentioned in 
this paper, and of referring to the invaluable collections of Leconte 
and Hayward. 
The following species, as already indicated, seems completely 
congeneric with the European Bembidion (Actedium) kusteri 
Schaum and B. (Act.) pallidipenne Illig. 
Bembidion (Actedium) lachmophoroides n. sp. 
Convex, posterior parts robust; head and thorax viridiaeneus; elytra 
smoky-yellow, with apex and a slightly post-median transverse fascia blackish, 
the latter slanting slightly forward from the suture. Head as wide as thorax 
at widest part, strongly alutaceous, rather sparsely punctured with very dis- 
tinct punctures; frontal striae broad, shallow, and parallel, the floor longi- 
tudinally rugose; antennae stout, piceus with the basal joint paler, interme- 
diate joints about twice as long as wide. Prothorax scarcely wider than an 
elytron, about one eighth wider than long, subcordate, narrower at base than 
apex, strongly alutaceous; median line well impressed, transverse impressions 
indistinct; disk impunctate at middle, slightly wrinkled transversely; sides 
with sparse, large punctures; base and apex strongly and longitudinally 
rugose; lateral margins narrow; hind angles not striate, slightly obtuse but 
not rounded, not prominent; basal impressions entirely obsolete except for 
the slightly broadened margin where the tactile seta arises. Elytra, alutaceous, 
together one half longer than wide, sides straight and subparallel in median 
third; humeri not prominent; striae moderately impressed, modertely punc- 
tured on basal two thirds; first, second, and seventh distinct at apex, others 
slightly abbreviated; seventh slightly less impressed on disk than sixth; third 
with two moderate foveae. Head and thorax piceous or reddish beneath; 
abdomen entirely flavo-testaceous ; Legs entirely pale. Length (cT 9) 4.25 
mm. Width (cf 9) 1.8-1. 9 mm. 
This species is most closely related to B. kusteri Schaum of 
Europe, but is distinct by the more complete elytral striation, 
the dark antennae, the posterior rather than anterior elytral 
markings, and the pale abdomen. The last character, however, 
may be due to the immaturity of the types. 
Both the c? holytope and 9 allotype were collected by Mr. 
F. S. Carr at Medicine Hat, Alberta, Sept. 8, 1923. By arran- 
gement with Mr. Carr the holotype will be deposited in the 
Canadian National Museum; the allotype is in my own col- 
lection. 
The occurence of European groups, or even species, in North 
America is a common phenomenon of which Actedium is only 
an additional example (2, 3). The subgenus should be looked for
