posterior margin laterally and the lateral margination is as distinct as the 

 sutural ; the base is a little broken, but it is otherwise perfect. Length, 

 T^, breadth, 1-25"™. 



One specimen: No. 16873, Scarborough. 



G. variegata is only known from Michigan. 



Quedius deperditus sp. nov. 

 PI. XI., Fig. 2. 



A single left elytron, perfect but flattened so as to expose the whole of 

 the lateral face, appears to represent a species of Quedius, not far removed 

 from Q. capucinus Grav. It enlarges slightly from the base, the distal 

 half of the sutural border is minutely margined, the lateral fold is sharply 

 carinate and not blunt as in Q. capucinus, and the posterior margin squarely 

 truncate but laterally strongly rounded ; the surface is black with only a 

 trace of castaneous and has a rather more abundant though still sparse 

 punctuation as compared with the modern species. Length, 2°™; breadth 

 of dorsal surface, O-Q"" 



One specimen: No. 16874, Scarborough. 



Q. capucinus is reported from Alaska, Canada, Pennsylvania, Indiana 

 and Missouri. 



Fhilonthus claudus sp. nov. 



PI. XII., Fig. 1. 



A species of Philonthus appears to be represented by a pair of elytra 

 which are twice as long as broad, broaden slightly posteriorly, are pro- 

 fusely and deeply punctate, have the lateral plication sharp and slight, 

 while the oblique truncation of the inner base indicates a rather large 

 and long scutellum. They are of ths same size and shape as in P. aeneus 

 Rossi, which they approach more nearly than the other species, but the 

 punctuation is distinctly coarser and deeper, and if anything more profuse. 

 It is also dead black, instead of having a steely lustre. Length, 2-5°™ ; 

 breadth, 1-25"". 



Two specimens : Nos. 16875, 16876, Scarborough. 



P. aeneus is a cosmopolitan species, and in this country has been re- 

 ported from the Hudson Bay Territories, Canada and Lake Superior and 

 the Morthern United States from Massachusetts to Colorado and Missouri.
