VOL- 68 TERTIARY INSECTS FROM SIBERIA COCKERELL 5 



spotted; costal margin narrowly suffused with dusky to apex; ve- 

 nation so far as visible agreeing with Liinnephilus gravidus Hagen, 

 except that the tip of the longer enclosed anal cell is at the same 

 level (distance from base) as the fork of radial sector, indeed slightly 

 more apicad, the wing evidently being shorter. The broad apical 

 portion resembles that of the Limneyhilus. End of discoidal cell 

 from tip of wing 7 nun. ; length of discoidal cell 5.5 mm. ; length of 

 cellula thyridii about 5.3 mm., not going far basad of discoidal; 

 veins delicate, pale-brown ; discoidal cell on first fork no longer than 

 breadth of its squarely truncate apex. 



Tertiary of Kudia River, Siberia.

This seems a very convincing Limne'philus., but it must be ad- 

 mitted that the fossil Phryganea longirostris Hagen has a similarly 

 broad wing, while P. duhla Pictet (which Pictet 

 took for a Limnephilus) has the first fork going 

 no great distance basad of apex of discoidal cell. 

 P. duhia has a fourth fork, which our fossil lacks. 

 All things considered, this surely must be a Limne- pio. 3.— end of 

 philiis; a matter of interest since Limnephilidae are discoidal cell 

 absent from Baltic amber. Assuming that the kecultds 

 family invaded the Palaearctic region at a later 

 date than the amber, we may get some light on the age of the 

 Siberian deposit. Limnephilidae are found (two species) in the 

 Miocene of Florissant. 



A second specimen referred to LiTiinephilus recuUus is less perfect, 

 but shows the base, with both inclosed anal cells as usual, and the 

 characteristic curve in the radius above end of discoidal cell. The 

 apical area is not so conspicuously pale as in the type. The apex 

 of the cellula thyridii is seen to be extremely oblique, a character 

 favoring Phryganea rather than Limnephilus.

PATROBUS(?) KUDIENSIS, new species 



Plate 1, fig. 10. 



Elytron 7.8 mm. long, 2.9 wide, nearly parallel-sided except at 

 ends; humeral angle rounded, without tooth or prominence; apex 

 broad, not acute, but not truncate; surface as preserved dull, ap- 

 parently minutely granular, but not punctate, the color coffee- 

 brown; eight well-defined but delicate striae, not counting two fine 

 closely adjacent lines on shelflike outer margin; striae not punctate, 

 and no punctures between striae on disk; submarginal punctures 

 feebly indicated.
