Oxydrepanus rufus (Putz.) : Of this common Cuban 
species I took a small series at Homestead, near the south- 
ern tip of the mainland of Florida, in June, 1929. They 
were in floating vegetation in pools, the usual habitat of 
species of this genus. O. rufus is plain rufous, shaped like 
a Clivina but small as a Dyschirius, 3 mm. or less in length. 
From both the genera mentioned it differs in having the 
tips of the apical segments of both pairs of palpi finely 
produced. 
Pseudaptinus ( Thalpius ) cubanus (Chd.) : one specimen, 
also from Homestead, June, 1929, was taken in trash be- 
side a flooded pool. It has been compared with a series 
from Cuba one of which in turn has been compared with 
Chaudoir’s type by Mr. Rene Oberthlir, in whose collection 
the type now is. The species is easily known by the very 
dull surface, caused by the fine, very dense punctuation. 
Selenophorus discopunctatus Dej. ( chokoloskei Leng) : 
I have several specimens of this species from Dunedin, 
Florida, from Mr. W. S. Blatchley. Leng’s types were 
from Chokoloskee and Everglade, Florida. My specimens 
answer Leng’s description perfectly, and at the same time 
are indistinguishable from our large series of the common 
discopunctatus , which ranges over all the West Indies and 
much of South America. 
MEGACEPHALA (TETRACHA) AFFINIS ANGUSTATA CHEV. 
( COLEOPTERA : ClCINDELID^] ) 
North of Mexico 
Of this species, not before recorded from the United 
States, I took four specimens at Brownsville, Texas, June 
II to 16, 1933. They were under street lights at night 
along the river just above the town, running with numer-
