Psyche 
[June-Sept. 
sides slightly, almost evenly arcuate; base and apex as 
usual; disk very convex, not distinctly impressed, incon- 
spicuously punctate. Scutellum not distinctly punctate. 
Elytra about 1/8 wider than prothorax; sides subparallel 
basally, broadly rounded posteriorly to near apex, where 
strongly sinuate (as usual) ; disk relatively closely and 
coarsely punctate, secondary punctation very fine, scarcely 
detectable; surface rather shining. Lower surface dull and 
pubescent (as usual). Length between 2 1/5 & 2%; width 
1 mm. 
Haiti: holotype (M. C. Z. no. 21,790) from Trou Caiman 
(a large fresh lake in the Cul-de-Sae about 25 km. northeast 
of Port-au-Prince), Nov. 15-20, 1934, in floating aquatic 
vegetation; 2 paratypes from vicinity Port-au-Prince, fur- 
ther data accidentally omitted. 
As compared with T. schwarzi, sethiops is much more 
shining, with coarser primary and much finer and less obvi- 
ous secondary elytral punctuation and longer and more 
matted pubescence. The antennae are similar, with 7-jointed 
clubs, which distinguish the species from crotchi Lee. (type 
seen) and politus Casey (paratype seen, borrowed from the 
U. S. N. M.) of the United States, which have 6-jointed 
antennal clubs. 
Pelonomus Er. 
The following material constitutes an informal revision 
of all the species of this genus found north of South Amer- 
ica.

Not Antillean (Texas and probably neighboring regions) : 
Leconte’s types (examined by me) are from the “southern 
and western states.” All are $ $ without more definite 
locality. They belong to the Texan form, of which we pos- 
sess also 10 $ , 10 ? labeled “Tex.” This typical form is 
characterized by a relatively broad (but somewhat vari- 
able) prosternal fissure behind the eye and by having the 
claw joint of the $ front tarsus very broad, widest near the 
base.
