foothills of the Massif de la Hotte, southwestern peninsula, 
2-4,000 ft., Oct. 10-24, 1934, taken in the same situations 
as the preceding. 
The relatively weak convolutions of the prothorax dif- 
ferentiate this from clavicornis, hubbardi, and congener , 
and give it a slightly Helmis-like aspect.

Grouvelle, Bull., Soc. Ent. France 1896, p. 17. 
Cuba and Haiti : described from the former without more 
definite locality. I have before me a specimen (over 4 mm. 
long) supposed to be from Cuba and one (3!/2 mm.) from 
the northeastern foothills of the Massif de la Hotte, Haiti, 
about 3,000 ft., Oct. 12, 1929. These specimens differ from 
luteus Lee. of the United States just as described in Grou- 
velle’s key ( l . c .) . The Haitian specimen was secured from 
the same fallen sappling which yielded the allotype of Pse- 
phenops haitianus. Another specimen was seen at the cross- 
ing of the auto road and Riviere Glace a few miles away, 
but flew from the edge of my net before I could reach it.

Journ., New York Ent. Soc. 12, 1904, p. 204. 
Jamaica (and Texas) : described from the latter, from 
Brownsville. I have specimens from Brazoria Co., Texas, 
and one from Kingston, Jamaica, Aug. 27-29, 1934, taken in 
vegetation in the edge of a small pond. The Kingston speci- 
men is not quite so roughened above as the Texan ones, but 
agrees well otherwise. 
11. Throscinus aethiops n. sp. (PI. Ill, fig. 7) 
Elongate oval, convex; rather shining black above, lower 
surface and appendages reddish except antennal club black ; 
pubescence moderate, longer than in schwarzi, tending to 
mat as in crotchi Lee. Head with front pubescent, not 
very closely punctate, somewhat shining (when pubescence 
removed) ; antennae with club 7- jointed (i. e. 5th joint 
stouter than 4th and distinctly triangular), 3rd joint some- 
what longer than 4th. Prothorax just over 1/2 wider than 
long, much narrowed anteriorly practically from the base ;
