488 SUPPLEMENT. 
GEREUS (p. 261). 
Mr. Wickham has been kind enough to send us the Barids obtained during his 
recent expedition to Mexico, and amongst. them are various additional species of this 
genus. The following were also sent, in addition to those specially mentioned below, 
from Cuernavaca or Puente de Ixtla, Morelos :—G. gracilis (3 2), G. picumnus, 
G. bicruciatus, G. tonsilis, G. baripes ( g)e and G. pallidicornis (@ ). 
Geraus rectispinis ( p. 265). 
To the localities given, add: :—MExtco, Cordova (Knab, in U.S. Nat. Mus.). 
A fully-developed male from Cordova, evidently conspecific with the Jalapa 
specimens here included under G. rectispinis, has the prosternal spines fully as long 
as the elytra and bent downwards at the tip, and the smooth, circular prosternal 
cavity very large and deep. 
32 (a). Gereus squamirostris, sp.n. (Tab. XXIII figg. 15, 15a, 3; 16, 2.) 
Oblong, rhomboid-ovate, black ; somewhat thickly clothed with narrow ochraceous or whitish scales, those on 
the elytra arranged in two rows along each interstice (sometimes increasing to three at the base), the 
vestiture of the under surface coarser and closer. Head sparsely punctate ; rostrum (¢ ) a little longer 
than the head and prothorax, strongly arcuate, rather stout, much thickened towards the base, densely 
punctate, squamose above and beneath, (@) abruptly flattened, widened, bare, and almost smooth from 
about one-third from the base, the basal portion stout, arcuate, squamose above, and closely punctate, 
the antennee inserted near the middle inthe ¢ and at the basal third in the 9. Prothorax not much 
broader than long, rounded at the sides anteriorly, constricted in front; densely punctate, with indications 
of a smooth incomplete median line. Scutellum small, almost bare. Elytra a little wider than the 
prothorax, rounded-triangular, narrowly punctate-striate, the interstices rugose. Beneath densely 
punctate ; first ventral segment slightly depressed down the middle in the d. Anterior coxw widely 
separated. Tibi feely unguiculate. , 
3g. Prosternum. armed with a small conical tubercle in front of each coxa. 
Length 33-4, breadth 13-13 millim. (¢ 2.) 
Hab. Muxico, Cuernavaca in Morelos (Wickham). 
Two males and four females. Near G. finitimus (Casey), but with a less transverse 
prothorax, the rostrum of the male squamose above and beneath and less evenly 
arcuate, much thickened at the base in both sexes, the anterior tibiz of the male 
feebly unguiculate, the prosternum armed with small conical tubercles as in G. bituber- 
culatus *. The sexual differences in the form of the rostrum are almost as strongly 
marked as they are in G. hospes. 
32 (s). Gerwus subinermis, sp.n. (Tab. XXIII. figg. 17, 17a, 3.) 
Rhomboid-ovate, black, somewhat thickly clothed with narrow whitish scales, “thoes on the elytral interstices 
biseriately arranged. Head finely punctate; rostrum (¢) regularly arcuate, gradually thickened 
towards the base, a little longer than the head and prothorax, and closely punctate, (9) flattened, 
widened, and almost smooth from about the basal third, the basal portion stout and closely punctate. 
* J have seen two specimens only of G@. finitimus, from Texas, both males, one with the prosternal spines 
reduced to small tubercles as in the present species.
