similarly shaped aedeagus but with a less complex orificial 
plate. I am unable to separate a series of specimens taken on 
St. Croix by H. A. Beatty and another series taken on St. 
Thomas, V. I. collected in January, 1937, in the Stuart T. Dan- 
forth collection, from this Puerto Rico species-. 
Homoschema fraternum n. sp. 
Fig. 4 
About 2.5 mm. in length, 1.3 mm. in width, not very convex, 
finely punctate, reddish yellow with violaceous elytra and dark 
breast and abdomen. Head with a slight narrow elevation be- 
tween antennal sockets and a line running down the lower front, 
lower front flat. 
Type.— Male, U. S. N. M. Cat. No. 59196. 
Type locality. — San Juan, Puerto Rico, collected Oct. 13.
