Vol. xxii] EXTOMOLOGICAL XEWS 195 



Since then I have been interested in listing articles on this sub- 

 ject, and the titles, with comment, are herewith presented, rec- 

 ognizing, of course, that the list is not complete.

 mass, and then deposits its eggs therein. 



Mottlton^ J. T. — Flies riding on a tumble-bug. Amer. Entom.. vol. Ill,

 Noticed in ^Missouri, a small fly (possibly Limosina. from 

 the brief description), riding on a tumble bug.

Exhibited a specimen of one of the bird flies. Ornithomyia 

 avicularia, to which were attached by their mandibles several 

 specimens of IMallophaga.

Gives account of Limosina sacra on specimens of Atcuchns 



laticollis; also notes that larvae of Antherophagus (Crypto-

proposes the term "phorcsie' for this transportation of one 



insect by another.
