80 TERTIARY COLEOPTERA OF NORTH AMERICA. 



COCCINEI.LA sp. 



Coccinella sp. Chu^n.. Nat. Csuiad., XXII. loi (is'.5). 

 Vancouver Island, British Columbia. 



AD ALIA Mulsant 



A cosmopolitan genus, with a considerable number of species, of which 

 only three belong to the United States. In the earlier Tertiaries a single 

 species is found in Alsatia and another in Colorado. 



ADALIA SUBVERSA sp. nov. 

 PL IX. tio-. ;. 



A single specimen of a beetle is preserved, showing, indeed, verv 

 few structural features, but in its form, size, and in its markings reminding 

 us of the common "lady-bird" which crawls up our window panes in the 

 spring. It is preserved on a dorsal view and shows head, thorax, and 

 elytra in tolerably good preservation, together with one of the front tibiae. 

 The form and proportions of the prothorax and elytra are exactly as in 

 Adftliti l>ijii/ft(ita (Linn.), but they are more coarsely punctate, though there 

 is the same distinction between the thorax and elytra in the shallowness of 

 the thoracic puncta. The insect appears to have been uniformly light 

 colored, with only two submarginal lateral dark spots on the prothorax (in 

 which it agrees better with Adttl'ui frit/idtt Sclm. than with other species 

 of Adalia I and a rather large central spot on each elytron. In the general! \ 

 uniform light color of the thorax it differs from auv of the living species in 

 the I'nited States. It is also rather larger. 



Length, f>.3 mm.; breadth, 3.65 mm. 



Florissant, Colorado; one specimen, No. 4704. 



CHILOCORTS Leach. 



A cosmopolitan genus with a considerable number of species, of which 

 a large part are tropical or subtropical, and only t\vo occur in the I'nited 

 States and two others in Europe. Wt three species have been found in 

 the carlv Tertiaries of these countries, two in Alsatia and one in Colorado.
