genera. The rock is dense and gray, not unlike that of Floris- 

 sant, but with a more irregular fracture. It is presumed to be of 

 Miocene age and is reported to contain a flora including Quercus 

 platania Heer, Ginkgo adiantoides (Unger) Heer, T o xodiuTn disti- 

 chum (Linnaeus) Richard, Glyptostrobus europaeus (Brongniart) 

 Heer, Porana, new species, Cornus studeri Heer, Greiuia crenata 

 (Unger) Heer, Diospyros 'brachysepala Al. Braun, etc. This might 

 be as old as Lower Miocene, but additional information is much to be 

 desired. The flora is a warm temperate, not at all tropical, one ; the 

 insects give the same indication, but are remarkable for their rela- 

 tively large size as compared with their living representatives.'^ 



MECOPTERA. 

 Family PANORPIDAE. 



DINOPANORPA, new genus. 



Based on a hind wing, remarkable for its relatively gigantic size 

 and unusual breadth ; venation nearly as in Panorpa^ except that the 

 first cross- vein between the media and cubitus is very long and oblique, 

 a condition somewhat approached by Panorpa venosa Westwood. 

 The first division of the radius (R^) is remarkable for ending prac- 

 tically parallel with the costa, forming an extremely acute angle. 

 Scj leaves the radius only a very short distance beyond the termina- 

 tion of Sci, proceeding veiy obliquely to the costal margin. At the 

 base of the wing the media fuses with the cubitus for a short distance. 

 The wing is dark brown, with scattered light spots.

DINOPANORPA MEGARCHE, new species. 



Plate 1, fig. 1. 



Hind wing 30 mm. long and 11 wide in middle; dark brown, 

 with five rather narrow hyaline transverse bands represented in part 

 by series of spots ; the first by an elongate mark on lower half of wing 

 beginning at cubitus; the second by a longitudinally elongate stripe 

 below the costa, a larger one below the radial sector, and a vertical 

 series of four spots below the apical end of this; the third by two 

 large spots above, and two still larger below and beyond them; the 

 fourth by the upper two spots only, placed obliquely, the lower one 



' Kryslitofovlch has described the Ponina as P. sichota-alhiensis ; I have seen the type, 

 a very beautiful specimen. Last July my wife and I made collections in this Siberian 

 locality, which is on the Kudia River, a branch of the Amagu, about 4 miles from the 

 coast. The fossil insects of this collection are now being described ; the additional plants 

 will be described by Kryshtofovich. I also visited Nawa's Museum at Gifu, Japan, and 

 saw there a very fine series of Japanese fossil insects, apparently late Tertiary, but at 

 present unstudied.
