AMARIN/E 231 



ago are hitherto undescribed and the present opportunity is taken 

 to define them : 



Curtonotus labradorensis n. sp Body elongate, parallel, black, mod- 

 erately shining, not at all metallic, the elytra sometimes brownish; legs 

 piceo-rufous; head well developed, with prominent eyes and deep linear 

 strioles; antennae (o 71 ) as long as the head and prothorax, ferruginous; 

 prothorax two-fifths wider than long, the apex sinuate and with broadly 

 rounded angles, subequal to the base in width, widest at the middle, the 

 sides evenly rounded, becoming sinuate and subparallel for some dis- 

 tance before the angles, which are slightly more than right though sharp; 

 foveal region coarsely punctate, the punctures fine and obsolescent api- 

 cally and also medio-basally; foveae rather long, linear, never wholly 

 confluent, the carinae short and obtuse; elytra nearly two-thirds longer 

 than wide, not (cf ) or quite evidently (9 ) wider than the prothorax, the 

 striae moderately coarse to finer or less impressed, always distinctly 

 punctate, the lateral series very widely interrupted; surface (9 ) slightly 

 alutaceous. Length (cf 9) 9.8-10.8 mm.; width 3.65-4.0 mm. Labra- 

 dor (\V. St. Modest). Eight examples. 







There is some variation in the degree of impression of the elytral 

 striae, flatness of the intervals, coarseness of the punctures and length 

 of the scutellar stria. The middle tibiae of the male are very broadly 

 swollen on the inner posterior side, the two subapical denticles on 

 the inner side small. The species may be placed near hudsonicus 

 Hayw., but it is larger in size and not in the least metallic. The 

 basal joints of the hind tarsi are grooved externally. 



Curtonotus scrutatus n. sp. Elongate, rather more convex and smaller, 

 shining, black to piceous-brown, the legs piceous or paler; head smaller 

 than in the preceding but otherwise nearly similar, the eyes rather large 

 and prominent; prothorax nearly similar, the foveae rather longer and 

 still more linear; elytra nearly similar in outline, striation and punctu- 

 ation but more convex and, in the male, distinctly wider than the pro- 

 thorax. Length (c/ 1 ) 9.0-9.5 mm.; width 3.2-3.35 mm. Labrador (W. 

 St. Modest). Two examples. 



This species while allied rather closely to labradorensis, differs in 

 its narrower form, more convex surface, smaller head and espe- 

 cially in the conformation of the middle tibiae of the male, which, 

 from a posterior viewpoint, are not very broadly swollen within 

 but more slender and only very obtusely thickened just below the 

 middle; the tooth itself is more prominent and acute however; it 

 may be placed next to labradorensis. 



There are numerous species allied to brunnipennis Dej., from the 

 more southern localities of the continent; those at hand may be 

 differentiated among themselves as follows:
