724 SUPPLEMENT. 
coxal process of 1 triangular ; legs very short, rather stout, hairy, the femora unarmed, the tibie with a 
short claw arising from the outer apical angle, the third tarsal joint bilobed, the tarsal claws short, 
divergent, simple ; body oblong-ovate, winged, clothed with long hairs and pectinate scales. 
The minute species from which the above characters are taken is very like a Ptinus. 
The prothorax and elytra are as hairy as in Ketyrsus. The scales (fig. 256) are 
pectinate, as in a few species of Otidocephalus. 
1. Ptinopsis floccosus, sp.n. (Tab. XX XV. fige. 25, 25a, 0.) 
Shining, nigro-piceous, the prothorax and elytra fusco-castaneous, the antenne and tarsi rufo-testaceous ; 
above clothed with radiato-pectinate, pure white scales intermixed with very fine, long, erect, white and 
fuscous hairs, the scales on the prothorax mostly clustered along the sides and base and those ou the 
elytra condensed into three irregular transverse fascie, separated by barer interspaces, the fuscous hairs 
clustered into a dense patch on the disc of the prothorax and occupying a transverse space across the 
middle of the elytra; the sternal side-pieces densely clothed with pectinate white scales, the legs albo- 
pilose. Head very finely punctate, depressed around the eyes. Prothorax swollen at the middle, sparsely, 
irregularly punctate. Elytra very finely punctate-striate, the strie more deeply impressed towards the 
base and shallow at the sides, the interstices almost flat. Beneath very sparsely, finely punctate. 
Length 23, breadth 1,4, millim. 
Hab. Guatemata, Cerro Zunil (Champion). 
One specimen. 
CHOLINA. 
CHOLUS * (p. 291). 
Cholus discolor (p. 294). 
To the localities given, add:—Costa Rica, Pozo Azul, Savanillas de Pirris 
(Underwood). 
Cholus calvescens (p. 296). 
To the localities given, add :—Costa Rica, Miravalles, Savanillas de Pirris, Azahar 
de Cartago (Underwood). 
Five more specimens of the var. costaricensis have now been received, one of them 
with the scales ochreous (instead of pure white) and one with the subapical fascia 
reduced to a few spots. 
Cholus xanthospilus (p. 297). 
To the localities given, add:—Costa Rica, Cariblanco, Sarapiqui (Lankester), 
Savanillas de Pirris (Underwood). 
Two abraded specimens. It is possible that C. xanthospilus will prove to be yet 
another form of the variable C. calvescens when sufficient material is available for 
examination.
