Psyche 
[June 
Zoology, no. 19532) from Cayamas, Sta. Clara, Cuba, Jan. 
17, Mar. 8 & 9., E. A. Schwarz. 
The lack of plagiation and the narrower form distinguish 
this species from the two described above; the striation of 
the elytra is intermediate; the form of the prothorax and 
presence of anterior dorsal puncture of elytra are as in 
plagiata. Of other described species this is apparently 
close only to unicolor Chd. of Mexico, which is described as 
having the antennae brown with pale bases and the legs 
brown with reddish articulations. Antennse and legs are 
clear testaceous in the Cuban species. 
101. Coptodera f estiva Dej. 
102. Coptodera unicolor Chd. 
103. Microlestes poeyi (J.-Duv.) 
104. Apristus sericeus n. sp. 
Piceous, silvery aeneous above, appendages piceous ; up- 
per surface very heavily alutaceous, lower surface less so. 
Prothorax about a third wider than long (by measurement) , 
much narrowed behind; sides sinuate before the almost 
right but only slightly prominent basal angles. Elytra with 
striae almost entire but very broad and shallow, faintly ir- 
regular but not punctate; third stria with two large and 
conspicuous impressions, just before middle and near apical 
fourth. Length -+- 3^2 mm. 
Holotype (Museum of Comparative Zoology no. 19533) 
and 7 paratypes from Soledad (near Cienfuegos) Cuba, 
Oct. 19, Dec. 3; all taken running on dry sand in the sun 
on the banks of the Arimao River. 
This species may be distinguished from all other Amer- 
ican Apristus by its shallow elytral striae combined with 
very heavily alutaceous surface. The species is apparently 
unique also in the large size of the dorsal punctures of the 
elytra. The genus has not been known before from the 
West Indies.
