coarsely punctate. Length (cf) 8.5 mm.; width 2.8 mm. Labra- 

 dor (W. St. Modest), Sherman laeviceps n. sp. 



Form rather slender, not quite so parallel, shining, rufous, the head and 

 prothorax somewhat darker; legs rufous; head three-fourths as wide 

 as the prothorax, with rather large and moderately prominent eyes; 

 nuchal constriction deep, punctate; anterior sulci very short, feeble 

 and irregular; epistoma with a transverse ridge, feebler and straighter 

 than in the preceding; antenna much shorter and thicker, rufous, 

 much less than half as long as the body; prothorax a fourth to two- 

 fifths wider than long, the sides broadly, evenly rounded and finely 

 reflexed, becoming parallel in basal fifth or sixth, the angles right 

 and sharp; anterior impression obsolete, with a very few punctures, 

 the apical beading subobsolete medially; median stria only a little 

 coarser but very deep basally; foveae smaller than usual, rather deep, 

 punctate and distinctly binary, the carina distinct, very close to the 

 edge; elytra three-fourths longer to nearly twice as long as wide, two- 

 fifths wider than the prothorax, very gradually arcuately narrowing 

 behind; striae fine, slightly impressed suturally, the discal obsolete 

 at apex; punctures very fine and slightly uneven, close-set; outer 

 striae very feeble; third interval remotely tripunctate. Length 

 (cf 9 ) 8.0-9.0 mm.; width 2.7-3.0 mm. Alaska (St. Paul Island). 

 A large series. insularis n. sp. 



The species labradorinus, minuens and tennis have been united 

 with septentrionis Dej., in our collections and lists, but they are 

 apparently not the same; septentrionis has been traced from north- 

 ern Europe to Kamchatka, but probably does not cross the Rocky 

 Mountain divide, the species of eastern North America being almost 

 invariably distinct from the Pacific species even in comparatively 

 northern latitudes. The multiplicity of species, as shown above, 

 they sometimes being abundantly distinct among themselves, as 

 in the case of tennis and labradorinus, tends to prove that all are 

 distinct from septentrionis. Septentrionis is usually compared with 

 excavatus Payk. (rufipes Duft.) and was for a long time considered 

 identical, but a specimen of the latter now before me, differs much 

 from the three species mentioned, in its more abbreviated form, evi- 

 dent subapical sinus of the elytra and in having th'e median stria of 

 the pronotum but little coarser basally, differing in this way from 

 labradorinus and minuens but resembling tenuis; this, however, has 

 a larger head, with very much larger and more prominent eyes. 

 Rufipes Lee., may or may not be still another species; I have not 

 been able to view the type, which seems to be larger in size than any 

 of the above 10 mm., according to the record. Insularis may be 

 allied to fulvus Mann., from Kodiak Island, but there is nothing to
