New West Indian Carabidx 
127 
but appearing longer, widest near the front ; posterior an- 
gles not prominent ; lateral margins distinct, narrowly 
raised; disk alutaceous, punctate like head, with distinct 
median impressed line abbreviated at base and apex. Elytra 
deeply, nearly evenly striate; strise impunctate; intervals 
convex, alutaceous. Length 5-6 mm. 
Holotype (Museum of Comparative Zoology no. 19543) 
and 9. paratypes from Soledad (near Cienfuegos) Cuba, 
Sept. 2 (B. B. Leavitt), June, Oct. 21, Nov. 7 & 9, most of 
the specimens from flood debris ; 1 paratype from Baragua, 
Cuba, Oct. 28, at light, L. C. Scaramuzza (United States 
National Museum). 
This and the following species must be near Pseudaptinus 
elegans (Chd.) of Brazil, but are said by M. Oberthiir, to 
whom I am indebted for comparisons of West Indian speci- 
mens with Chaudoir’s type, to be distinct. I hope in my 
next paper to be able to publish the distinguishing charac- 
ters. Both West Indian species, especially the one from 
Grenada (below) are near Ps. lecontei Dej. of the United 
States, too, but lecontei , of which I have seen several speci- 
mens, has the prothorax more dilated anteriorly and is more 
shining. 
Pseudaptinus (s. s.) thaxteri n. sp. 
Exceedingly similar to marginicollis. The preceding de- 
scription may stand for the present species except that the 
side margins of the prothorax are obsolete and the color 
less contrasting. Length about 5 mm. 
Holotype (Museum of Comparative Zoology no. 19544) 
and 1 paratype from Grand Etang, Grenada, R. Thaxter. 
This species is, of course, named in honor of the collector, 
the late Professor Roland Thaxter. 
126. Pseudaptinus (Thalpius) cubanus (Chd.) 
127. Pseudaptinus (Thalpius) insularis Mutchler. 
This species is described in the American Museum (New 
York) Novitates no. 686, 1934, p. 4.
