128 MEMOIRS ON THE COLEOPTERA 



It is said to have somewhat the appearance of funestus, which 

 however has black legs and is otherwise quite different, it may be 

 placed just after junestus in the table. 



H. obesulus Lee. Oblong-oval, slightly convex, black, shining; 

 prothorax almost twice as wide as long, narrowed at apex, the margin 

 not depressed; hind angles right, the base obsoletely bi-impressed 

 [" utrinque obsolete biimpresso " in the original], slightly rugoso-punctu- 

 late; elytra a little wider than the prothorax, the apices obliquely sinu- 

 ate, the striae deeper posteriorly; intervals slightly convex, the third 

 unipunctate; antennae testaceous at base. Length 8.7 mm. Oregon. 

 A single female example. 



This species is now considered a synonym of basilaris Kirby, 

 but how justly I have no way of knowing in the absence of authen- 

 tically identified examples of Kirby's species, which comes from 

 the far north, Lat. 54, and has the elytra chestnut-black and the 

 trochanters dark yellow characters said by LeConte to be at 

 variance with obesulus. I am thoroughly disposed to doubt the 

 present synonymy and also doubt the synonymy of desertus Lee., 

 with ochropus Kirby, as at present maintained; desertus is from a 

 far more southern habitat. 



H. varicornis Lee. Oblong-oval, subdepressed, black, shining; 

 head smooth, the foveae punctiform, the frontal suture fine, scarcely 

 distinct; palpi not truncate but subacute at apex; antennae black, the 

 first joint ferruginous; prothorax quadrate, rather short, twice as wide as 

 the head, fully one-half wider than long, slightly narrowed anteriorly, 

 the sides moderately rounded, the base rectilinearly truncate, the hind 

 angles right, not rounded, feebly explanate; transverse impressions almost 

 obsolete, the stria extremely fine, abbreviated anteriorly, the foveae short 

 and broad, almost contiguous medially, sharply separated from the 

 explanate angles, not deep, very finely and sparsely punctate; elytra 

 slightly sinuate near the apices, finely striate, the intervals feebly convex, 

 the third posteriorly unipunctate, the scutellar stria long; legs black. 

 Length 8.8 mm.; width 3.8 mm. Lake Superior. 



Allied possibly to sejunctus and renoicus of the above table, in 

 both of which species, however, the first two antennal joints are 

 pale; it seems to differ conspicuously from either of them in the 

 transversely and internally extended thoracic foveae. 



Group VIII (spadiceus] . 



There is but little to be said concerning this small group of 

 two species, except that in general habitus it departs from any of
