New West Indian Carabidx 
87 
Nov. 24, Dec. 1, taken in gravel bars beside woodland 
brooks. 
For comparative remarks see under the following species. 
Perileptus (s. s.) jeannel! n. sp. 
Form closely similar to that of the preceding species; 
depressed; piceous; mouth, bases of antennae, palpi, legs, 
and feet rufescent to testaceous. Head: antennae very 
slender, median joints about four times as long as wide; 
head otherwise about as, in columbus. Prothorax cordate, 
strongly constricted at base, which is very slightly less than 
two thirds as wide as widest part ; basal angles right. Elytra 
with sutural stria very lightly impressed, obsolete at base; 
other striae barely or not at all suggested by irregularities 
of the elytral surface ; three dorsal punctures on position of 
(obsolete) third stria. Length 3 mm. or slightly less. Male 
not known. 
Holotype $ (Museum of Comparative Zoology no. 19508) 
and 6 paratypes (2 in collection Jeannel) from Kingston, 
Jamaica, Feb. 14, 1928; taken in gravel bars of a large 
stream in the outskirts of the city during half a day of col- 
lecting, all that I have ever done on the island. 
This- species is close to the preceding, but is perfectly 
distinct by the much darker color, more slender antennae, 
relatively narrower prothoracic base, and slightly larger 
size. Both species belong to the areolatus group of Perilep- 
tus. Dr. Jeannel, who has very kindly examined specimens 
sent to him and confirmed my identification of them as Peri- 
leptus, writes that the two West Indian species differ from 
previously known species of the areolatus group only in 
being more depressed, more closely punctate, and with 
the elytral striae more effaced. They are especially closely 
related to P, nigritulus Woll. of Madeira. 
No species of Perileptus, and indeed none of the Perilep- 
tini, has been known before from the New World. The 
West Indian species are especially interesting in that the 
well characterized areolatus group to which they belong is 
known otherwise (according to Dr. JeanneFs fine mono-
