BWRMECOPHILOUS INSECTS FROM CUBA.
BY WILLIAM M. &NN?
Bureau of Entomology, Washington, D. C.
A colection of myrmecophilous insects that I made in Cuba the past winter? though very small, indudes several genera new to the 'fauna of that island. In addition to records of these? I have de- :scribed a Clavigerid beetle? Fustiger schwar& sp. nov., from a -specimen in the U. S, National Museum.
Hyrmecophila amerkana Sauss.

1 am foIlowing Sdimmer (Zeitschr. wiss. Zool. Bd. xciii. Heft. 3? p. 432) in considering this to be the same as H. prenolepdis Wasm. My specimens were taken with Prenolepis longicornw 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 lbeetle, ~o~u~cera madem 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 Sn 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 i3me on a high shelf. When I looked into these I found them ananted by populous colonies of Crematogaster lineolata Say, and with these, severa? adults of Myrmecophila pergandei Scud. The .crickets had either climbed the five feet of pole 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 >af some observations made on a related species of cricket on various %lands in the Southwest Pacific. I found the cricket abundant,

HEMIPTERA.
Rhitidoporus indentatus Uh'er.
Mina Carlota, Trinidad Mts.
Two specimens taken in a flourishing colony of Solenopsis gemin- ata Fabr. indicate that this species resembles some of our North American species of Thyrecoris in having rnyrmecophilous tend- encies.
COLEOPTERA.
Fustiger schwarzi sp. nov.
Length, 1.50 mm. Color reddish brown, the elytra somewhat lighter than the rest. Head nearly three times as long as broad; as broad in front as behind; sides subparallel; front transversely impressed between the eyes; occipital corners obtusely angulate, border feebly concave. Eyes small and convex, located at middle *
of sides of head.
Antennz one and one-fourth times as long as head; terminal joint slightly concave at middle, thickened at apical half, the end broadly rounded. Prothorax as broad as long? with a large median fovea along basal half; sides evenly convex- Elytra taken together about as long as broad, broadest behind,, with narrowly rounded humeral angles and convex sides. Abdo- men very deeply impressed transversely at base, tuberculate on either side and with a rather scant brush of yellow hairs. First segment margined at sides for entire length. Propygidium nearly four times as broad as long.
Shining. Head, antenne and basal third of elytra foveolately punctate. Abdomen minutely punctate above, the ventral sur- face with abundant rather coarse punctures, fine recumbent white hairs moderately abundant everywhere except on abdomen. Described from a unique female taken at Cayamas, Cuba, January 2, 1904, by E. A. Schwarz. It was in the nest of an ant of which no specimens were preserved.

Several specimens from one nest of Prenolepis longicornis Latr.
