HETEROMERA. 541 
PHALERIA (p. 217). 
Phaleria guatemalensis (p. 218). 
To the locality given, add :—Mexico, Mazatlan (Héqe). 
Sent in abundance from Mazatlan on the Pacific coast. Mexican specimens differ 
from those from Guatemala in having the elytral markings entirely obliterated, or, at 
most, represented by a post-median sutural streak and a small discoidal spot. 
Phaleria dytiscoides (p. 218). 
To the localities given, add :—Mexico, Mazatlan (Hége). 
Also sent in abundance from Mazatlan. P. panamensis is perhaps a variety of this 
species; but it is duller and comparatively less elongate, the elytra are much more 
variable in colour, the thorax is more transverse, a little less narrowed in front, and 
usually testaceous, or, at most, with the base infuscate. 
Phaleria pilatei (p. 220). 
Three specimens of a Phaleria from Vera Cruz (Hoge, Flohr) agree with Chevrolat’s 
description of P. pilatei, except that they have not the head ‘inter oculos dense 
sulcato, dein arcuatim costato.” 
Phaleria insularis (p. 221). 
To the Mexican locality given, add :—Mazatlan (Hége). 
Many specimens from the Pacific coast, agreeing with those from the adjacent 
islands. 
BYCREA (p. 221). 
Bycrea villosa (p. 222). 
To the Mexican localities given, add :—Atlixco in Puebla (F. D. G.), Santo Domingo 
Tehuantepec (Richardson). 
Found in numbers by Mr. Godman in the nests of Gcodoma cephalotes. 
apparently with brown patches ; the elytra with irregular rows of very distinct, rather coarse punctures, 
which extend outwards to the lateral margin but not to the apex. 
Length 43 millim. 
Hab. Cotomsta, Bogota (coll. F. Bates). 
Two examples. Readily separable from E. marmoratus by the very distinct irregular series of rather 
coarse punctures on the basal two thirds of the elytra, the pubescence on the latter not forming angulated 
fasclce.
