MYRMECOPHILOUS INSECTS FROM CUBA. 
By Wiuuiam M. Mann, 
Bureau of Entomology, Washington, D. C. 
A collection of myrmecophilous insects that I made in Cuba the 
past winter, though very small, includes several genera new to the 
fauna of that island. In addition to records of these, I have de- 
scribed a Clavigerid beetle, Fustiger schwarzi, sp. nov., from a 
specimen in the U. S. National Museum. . 
ORTHOPTERA. 
Myrmecophila americana Sauss. 
Guantanamo; Cienfuegos. 
I am following Schimmer (Zeitschr. wiss. Zool. Bd. xci. Heft. 3, 
p. 432) in considering this to be the same as M. prenolepidis Wasm. 
My specimens were taken with Prenolepis longicornis Latr., the 
usual host. Besides its wide-spread distribution M. americana is 
interesting in that it lives only with this one species of ant, instead 
of taking up with almost any species, like our North American 
forms do. Assmuth (Zeitschr. f. wiss. Insektenbiol. 1907, Bd. iii, 
p. 363-364) has given an interesting account of the moving of a 
colony of the host ant to a new nesting site. The crickets and the 
beetle, Coluocera madere Woll. accompanied the ant column and 
entered the new nest with it. Myrmecophila does not always 
leave a nest when the hosts do, for specimens are frequently found 
in formicaries that have been deserted by the ants. In connection 
with the local distribution of Myrmecophila the following note is 
of interest. 
On Plummer’s Island, Maryland, in an open-air insectary, 
several cigar boxes used as breeding cages had been left for some 
time on a high shelf. When I looked into these I found them 
tenanted by populous colonies of Crematogaster lineolata Say, and 
with these, several adults of Myrmecophila pergande: Scud. The 
-crickets had either climbed the five feet of po'e that held the 
shelves, or they had been transported by the ants, perhaps as im- 
mature phases. I think the latter more probable, chiefly because 
of some observations made on a related species of cricket on various 
islands in the Southwest Pacific. I found the cricket abundant,
