No. 407.] A NEW MYRMECOPHILE. 857 
exhibited by the Thysanuran Lepismina and the mite Anten- 
nophorus. In these cases, as Janet has shown in an excellent 
paper,! the guest steals some of the liquid food while it is pass- 
ing from the mouth of one ant (Lasius umbratus mixtus Nyl.) 
to that of another. 
Before passing to a more detailed description of Attaphila, 
attention may be called to a few of its structural and taxo- 
nomic peculiarities : 
1. Up to the present time a genus of diminutive crickets 
(Myrmecophila) has comprised the only known myrmecophiles

Fic. 5. — Attaphila fungicola n. sp., female, ventral aspect. 
in the great Orthopteran order.? With Attaphila a genus belong- 
ing to a very different family, the Blattidæ, must be added to 
the long list of insect myrmecophiles. Considering that there 
is no family of Orthoptera apparently so well fitted to enter into 
symbiotic relations with ants, it is rather surprising to find that 
other myrmecophilous Blattidae have not been discovered, espe- 
cially in the tropics, where the family is rich in species.

the reader may be referred to an article in Psyche (1 900).
