78 ME. A. MURRAY ON THE GEOGRAPHICAL RELATIONS OF 



Note 21. — Eipporliinus. Similar remarks apply to this. 

 Note 22. — Acalles. Largely represented both in itself and by 

 allied genera in the Atlantic Islands. 

 Note 23. — Cossonus. Ditto. 



Note 24. — Lamia. The genus Lamia is too large to know 

 what type of it Heer referred his fossil to. I am in doubt and 

 have had to leave this blank. 



Note 25. — Lorcadion. I include the Mexican form Monilema 

 as part of Lorcadion in this inquiry, not as otherwise a bad 

 genus. 



Note 26. — Donacia. Lacordaire, in speaking of the Indian 

 and African species of Donacia, cites, as an interesting fact in re- 

 gard to their distribution, that they have more analogy with the 

 species of North America than with those of Europe. I cannot, 

 however, see it. 



Note 27. — Coccinella. The special genus or subgenus of a 

 fossil Coccinella can scarcely be distinguished. I have therefore 

 included several allied genera besides Coccinella, which makes it 

 cosmopolitan. Strictly confined to the modern subgenus, it has 

 been met with everywhere but in Polynesia and Madagascar. 

 The vast numbers in which it has often been met with, and the 

 appearance of flights of them migrating to other quarters, have 

 probably something to do with its wide distribution.

Note 1.— Gomplwcerus. This genus is divided into two sections, 

 of which the first is confined to Europe.
