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 Uhler. 

 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. 



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. Antennae 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, antennae 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.
