AMERICAN COLEOPTERA. 243 



of Phoenixville, to whom we are indebted for the exploration of the 

 locality in which the fossil insects were discovered. 



V. (mi II or). 



Two fragmentary elytra of smaller size than the preceding, afford 

 the only groundwork for the name above suggested. The stride arc 

 fine and with fine punctures, the intervals feebly convex, evidently 

 slightly rugulose, and probably, also sparsely punctulate. An impres- 

 sion of the scutellum remains which is broadly triangular, and not 

 different in form from that of Andrewsii. 



Eh/ fra (restored'). — Length .54 inch; 13.5 mm. Width (actual) 

 .15 inch J 3.75 mm. 



The form is therefore, almost exactly that of Andrewsii. 



PTEROSTICHUS. 



P. sp. 



Fragments of two elytra. Elytra striate, strige impunctured, inter- 

 vals moderately convex, smooth. 



A species apparently of the size of coracinus or sti/gicus is indicated, 

 but without more material it seems unnecessary to name it, or guess 

 as to its affinities. 



P.? sp. 



The greater portion of two elytra with the basal and apical ends 

 wanting, indicate a form of larger size than any of our eastern species 

 of Pterostichus. The elytral substance is in extremely bad state, being 

 wrinkled and cracked in such a manner as to render a description of 

 its surface impossible. It may be a Loplioglossus. 



CYMIKDIS. 

 C. aurora. 



Elytra. Striae moderately deep, indistinctly punctured, intervals 

 irregularly, biseriately punctulate, and very finely alutaceous. Length 

 .30 inch ; 7.5 mm. 



The greater portion of both elytra remain, somewhat distorted by 

 pressure and retaining much of the chitinous substance. A species 

 is indicated closely related to C. americana, but somewhat larger. 

 The punctuation of the intervals and the arrangement of the striae 

 near the tip, resemble so closely those of C//mindis, that I place the 

 species in that genus.
