power magnification) with indications of faint striae and 
appearing as if covered with fine scales giving them a silky 
appearance, possibly granulate punctate, submargin with 
setigerous punctures, apical angles rounded. Front tibiae 
with two elongate spines at upper end of the emargination 
(the outer one apparently bifid for about two-thirds its 
length), apical spine somewhat long; joints of the front 
tarsi shorter than those on the other legs, first joint slightly 
longer than the next two taken together and about as long 
as the apical joint, joints two, three and four gradually 
shorter, hind tarsi with the first joint slightly longer than 
the apical joint, other joints shorter, claws distinctly but 
shortly pectinate; hind tibiae, with spines similar to those 
on the middle tibiae, on the outer side. Length 4.5 mm. 
Type. Ensenada, Puerto Rico, June 17 to 19, collected 
by Dr. F. E. Lutz, on the side hill back of Canary Cottage, 
under stones, in a field containing numerous cacti. In 
American Museum of Natural History. One paratype. — 
Soledad, Cienfuegos, Cuba, October 26, collected by P. J. 
Darlington. In Museum of Comparative Zoology. Two 
paratypes.— Cayamas, Cuba, June 6, collected by E. A. 
Schwarz and Porto Rico, with no definite locality, collected 
by George N. Wolcott. In United States National Museum. 
Remarks . This new species resembles Aephnidius 
(= Masoreus) piceolus Chaudoir, and believing that it 
might possibly be that species I failed to describe it in the 
recent paper on “New Species of Carabidae from Puerto 
Rico” Amer. Mus. Novitates. No. 686. Since these descrip- 
tions appeared a specimen of this species from Cuba was 
submitted by Dr. P. J. Darlington to Mr. Rene Oberthur 
for comparison with the Chaudoir type. 
The reply from Mr. Oberthur stated the Cuban specimen 
was not Chaudoir’s species. The West Indian species dif- 
fers in having the antennae and legs stouter than the true 
piceolus (although still slender) and probably differs in 
other ways. 
The paratype from Cayamas, Cuba, is somewhat brown- 
ish black in color, possibly due to being collected before the 
coloring had fully developed.
