80 TERTIARY COLEOPTERA OF NORTH AMERICA. 



COCCINELLA sp. 

 Coccindla .?/?. Chagn., Nat. Canad., XXII, 109 (1895). 

 Vancouver Island, British Columbia. 



ADALIA 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. 

 PI. IX. lig. 6. 



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

 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 

 Adalia hipunctata (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 uniforml}^ light 

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

 which it agrees better with Adalia frigida Schn. than with other species 

 of Adalia) and a rather large central spot on each elytron. In the generally 

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

 the United States. It is also rather larger. 



Length, 5.3 mm.; breadth, 3.65 mm. 



Florissant, Colorado; one specimen. No. 4704. 



CHILOCORUS Leach. 



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

 a large part are tropical or subtropical, and only two occur in the United 

 States and two others in Europe. Yet three species have been fomid in 

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