of the Group Cerambycine. 21 
The species is evidently very nearly allied to //. bitus, 
Linn. The colour of the elytra is almost the same, but the 
pubescence has a slight greenish or yellowish tinge. The 
ridges of the prothorax are more numerous and a little less 
regularly transverse. ‘The fifth joint of the male antenna is 
without a distinct spine. ‘The head is more distinctly carinate 
between the upper lobes of the eyes. 
Hammaticherus punctulatus, sp. n. 
Nigro-fuscus, cinereo-pubescens ; prothorace supra transversim sat 
regulariterque plicato, plicis prope medium sinuatis, lateribus 
utrisque tuberculis duobus—uno medio, altero obtusiore paullo 
pone marginem anticam ; elytris elongatis, rufo-brunneis, cinereo 
leviter pubescentibus, subtiliter punctulatis, apicibus truncatis 
utrisque valde bispinosis; antennis (dg) quam corpore duplo 
longioribus, articulis tertio ad quintum spinosis, spinis valde 
recurvis, articulo quinto tertio equal. 
Long. 37-41, lat. 10-12 mm. 
Hab. Brazil. 
Blackish brown, with a pale greyish pubescence, with the 
emargination of the eyes covered with a bright golden pubes- 
cence. Prothorax crossed above by about eleven transverse 
ridges in addition to the raised anterior and posterior borders ; 
the sides each with two tubercles—one at the middle, the 
other, distinct though obtuse, a little behind the anterior 
margin. Elytra elongate, feebly and somewhat sparsely 
punctulate, reddish brown, with a faint greyish pubescence, 
each truncate and bispinose at the apex. 
This species may be distinguished from H. batus, Linn., 
and its allies by the punctuation of its elytra, by the second 
distinct tubercle on each side of the prothorax, and by having 
the fifth joint of its antenne equal in length to the third. 
In H. batus and H. mexicanus the fifth jot of the antennze 
is a little shorter than the third; the prothorax has a slight 
thickening of the ridges, or callosity, on each side near the 
anterior margin; the elytra are almost destitute of punctua- 
tion beyond the excessively minute pits from which the hairs 
of the pubescence spring. 
In H. punctulatus the stridulating surface of the meso- 
notum is less finely striated than in allied species; but I do 
not yet know whether this character may be relied on as a 
specific distinction. 
I. carthagene (Guér., MS.), a variety of /7Z. batus, Linn., 
with brown or reddish-brown elytra, which is found in 
Colombia and Panama, has a strong resemblance to the 
present species.
