Tertiary of Kudia River, Siberia. 



Holotype.— Cat. No. 69597, U.S.N.M. 



The general shape of the elytron might suggest Pterostichus or 

 Morio, but there is no humeral projection or point, and the inner 

 basal striae do not conform. As between Patrohus and Scarites I 

 have found it hard to decide, but the elytron agrees better with 

 Patrobus in that the submarginal sulcus fails to reach or approach 

 the apex, and has at its end a row of small punctures. Also, the 

 oblique groove mesad of this is indicated, though feebly. In the 

 genus Patrobus^ the species falls near P. calif orTdcus Motschulsky, 

 and is quite different from such species of P. longicornis Say, in 

 which the striae are punctured. In Leng's catalogue, P. calif ornicus 

 and its allies are referred to a distinct genus, Platidius^ and our 

 fossil should perhaps stand as Platidius kudieiisis. 



On the same stone, but on the other side, is a case of Indusia 

 comminuta. It may be added that Patrobus proper is essentially 

 a subarctic genus (Greenland, Alaska, Labrador, etc.), whereas 

 Platidius has its maximum development in more southern regions. 

 This tends to reinforce the suggested reference of the fossil to 

 Platidius. 



Family CURCULIONIDAE 



CLEONUS SHAREIPOFFI, new species 



Plate 1, fig. 11 



Elytron 8 mm. long and 2.6 wide, parallel-sided, as preserved 

 rather dilute brown; base truncate, apex broad but pointed; nine 

 rows of strong punctures, evanescent (apparently abraded) apically, 

 three or four punctures in one mm. ; between the roAvs of punctures 

 are very delicate longitudinal brown lines, not impressed; at the 

 beginning of outer third of apical half is an obtuse longitudinal 

 elevation or shoulder. The punctures are circular, not elongated. 



Tertiary of Kudia River, Siberia. 



Holotype.—C2Li. No. 69598, U.S.N.M. 



Numerous Tertiary species have been referred to Cleonus, but 

 few are as convincing as this, which has quite the aspect of the 

 modern genus. I have given it a name ro?nmemorating Mr. 

 Shareipoff, head man of the village of Amagu, who gave us much 

 assistance in our undertaking. 



ANTHONOMUS AMAGUENSIS. new species 



Plate 1, fig. 7 



Elytra brown, 4 mm. long and 1.3 wide, base broadly truncate, 

 humeral angles rounded, apex rather acute. Seven longitudinal 

 striae, consisting of rows of shallow punctures as in living species.
