and often on small isolated and deserted coral islands where one 
wondered how even the host ant could have reached and estab- 
lished itself. 
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 myrmecophilous tend- 
encies. 
COLEOPTERA. 
Fustiger schwarzi sp. nov.

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.

face with abundant rather coarse punctures, fine recumbent white 
hairs moderately abundant everywhere except on abdomen.

of which no specimens were preserved.
