3. A MIOCENE EARWIG. 



LABIDUROMMA EXSULATUM Scudder. 



Plate 1, fig. 6. 



Scudder only figured the female of this Florissant species ; oppor- 

 tunity is taken to figure the male (U.S.G.S., 1607, with reverse, 

 1606). Except for the large eyes, typical of Lahiduromma.^ one 

 might take the insect for a Forficula. It is possible to see the first 

 two joints of the anterior tarsi, and the second joint is heart-shaped, 

 as in Forficula. The first joint, however, is stout and swollen, pyri- 

 form in outline as seen from above. The last dorsal segment is ob- 

 tusely subangulate in the middle. The very stout forceps are broad 

 and contiguous basally, as in certain species of Forficula. 



In the very large collections from the Green River Eocene, no 

 Earwig has been found.

4. A FOSSIL BEETLE FROM WASHINGTON STATE. 



I am greatly indebted to Dr. F. H. Knowlton for the opportunity 

 to study a fossil elytron from a new locality, Deep Creek Canon, 

 near Spokane, Washington. It was found " in clay beds interbedded 

 with volcanic flows of Upper Miocene age, associated with a large 

 and beautifully preserved flora." At Doctor Knowlton's suggestion, 

 I am very glad to name it after C. O. Fernquist, of Spokane, who 

 collected it and has given much aid in collecting and forwarding 

 fossil plants. The species belongs to a well-known modern genus of 

 Carabidae. 



CALOSOMA FERNQUISTI, new species. 



Plate 2, fig. 8. 



Elytron 20.5 mm. long, 7 broad, the apex more produced and 

 pointed than in G. scrutator Fabricius; 18 longitudinal striae, which 

 are strongly punctured, or 19, counting the short inner basal one 

 which is about 4 mm. long; punctures connected transversely by 

 shallow sulci, as in living species; in middle of elytron about 11 

 punctures in 3 mm. longitudinally ; f oveae in fourth and eighth inter- 

 spaces (counting from inner margin) not very distinct, but essen- 

 tially as in C. scrutator. 



The G. scrutator compared is from Geneva, Ohio (Mrs. Nellie B. 

 Henderson). In the form of the elytron, with comparatively acute 

 apex, this is much more like G. externum Say, of the eastern United 

 States; it was on account of this feature that Dejean named Say's 

 species longiperune. Doctor Knowlton showed the fossil to Dr. E.
