in Switzerland they built on piles, while in Ireland and Scotland they 

 built on low islands ; on the other hand, in Venice they built on both piles 

 and islands. The tracings of the philologist of this Celtic people by means 

 of their language and their stories from Asia, as a wave of the great Aryan 

 race, have received additional confirmation by the discovery of bones of 

 the domesticated animals from Asia among their remains. This brief 

 sketch, only intended to embrace a few points, I hope will fee accepted by 

 you as such. 



NOTES ON COLEOPTERA, WITH ADDITIONS TO THE LIST 

 OF THE COLEOPTERA OF CINCINNATI.

Adranes Le Contei. 



While searching for rare beetles near Avondale recently, I turned over 

 a small beech log, partly decayed, that was honey-combed by a medium- 

 sized pale brown species of ant. On being disturbed, the ants rushed 

 about in great confusion ; among them I recognized several Adranes Le 

 Contei, 2l small beetle belonging to the family Pslaphidce. Adranes is one 

 of the most remarkable beetles known, both in habits and structure; it has 

 a minimum number of joints in the antennae — there being but two, the 

 usual number in the Coleoptera being about eleven, while in some of the 

 Longicorns there are twenty-seven. The eyes are entirely wanting, as in 

 some of the beetles found in caves; the abdominal segments are connate. 

 The species is quite rare in collections, and has never been recorded before 

 from this locality. 



On each side of the body and just back of the elytra is a tuft of brown 

 hair, and from it springs a tube from which the beetle exudes a fluid that 

 the ants are supposed to eat, and this will explaiu why the ants permit 

 these beetles to live in their nests. What Adranes eats is a mystery ; but 

 it is certain that the ants get more than they give in the association. T 

 was convinced that the ants were friendly to the Adranes, as I placed other 

 insects in the nest, which the ants immediately attacked with great fury 

 and soon tore them to pieces. 



"LADY-BIRDS." 



The terminal shoots of a cherry-tree were covered thicklv with Aphidas, 

 or plant lice; the leaves shriveled and turned brown; I thought the tree
