" Obion go-ovatus, convexus, rufo-ferrugineus, nitidus, glaber- 

 rimus; antennis extrorsum valde incrassatis pilosis, articulo 

 octavo prsecedente multo minore ; thorace lsevi, antrorsum ro- 

 tundato, angulis posticis supra elytra rotundato-productis ; 

 elytris disperse punctatis, subrugulosis.

I have not seen this species. M. Pippingskold collected it 

 in the island of Sitka under a stone. 



Mannerheim states that in form it comes very near the genus 

 Colon, but he rather referred it to Catops from the structure of 

 the antennse, although at the same time differing from both by 

 the polished smoothness of its body. From this indication it 

 should probably rank beside lucidus, Kraatz, and I have accord- 

 ingly placed it in this subdivision. 



2nd Subdivision. Body not polished and shining ; elytra trans- 

 versely strigose. 



51. C. strigosus, Kraatz. 

 Catops strigosus, Kraatz, Stett. Ent. Zeit. xiii. p. 441. 31. Fig. 46. 



Ovatus, rufo-ferrugineus ; antennis longioribus, 

 obsolete clavatis, ferrugineis; thorace trans- 

 verso, angulis posticis fere acuminatis; elytris 

 substriatis, evidenter transversim strigosis, apice 

 acuminatis. 



Long. \\ lin. 



The antenna? are slender, entirely reddish-brown ; first, second 

 and third equal in length ; fifth scarcely longer than those on 

 each side of it, half as large as the first joint ; seventh somewhat 

 longer and stouter than the foregoing, equal to the ninth and 

 tenth ; eighth scarcely half as long and a little thinner than the 

 seventh ; eleventh somewhat longer than the tenth, moderately 

 sharply acuminate. The head is red-brown, densely and finely 

 punctate. The thorax is nearly 2~ times as long as broad; at 

 the base it is of the same breadth as the elytra ; it is gradually 

 narrowed towards the front, gently rounded on the sides ; the 

 upper side is moderately densely clothed with golden-yellow 

 pubescence, coarsely granulated ; the anterior angles are obtuse,
