3. Macrocephalus panamensis, n. sp. (Tab. IV. figg. 12, ¢; 13, 9.) 
Macrocephalus panamensis, Champ., Handl. Ann. k. k. naturhist. Hofmus. xii. p. 200, fig. 25 
(scutellum), t. 9. fig. 40 (antenna) '. 
¢. Moderately elongate, attenuate behind ; head black, with an ochraceous stripe on each side behind the eyes ; 
pronotum brownish-black, rather broadly bordered with ochraceous at the sides from the lateral angles 
to the apex; corium and scutellum black, the latter with the median callus, a narrow curved fascia a 
little before the apex, and the apex of the median carina, flavous; the connexivum ochraceous, with a 
transverse black fascia before the middle; the antenne black, the second and third joints, and the base 
and apex of the fourth, obscure ferruginous; the body beneath ochraceous ; the anterior femora and tibis 
nigro-fuscous, the intermediate and hind legs fusco-testaceous; above and beneath, the basal joints of the 
antenne, the coxe and femora, and the two hinder tibie, sparsely studded with smooth minute granules ; 
the basal half of the pronotum and the basal third of the scutellum closely and somewhat coarsely, the 
corium and the rest of the scutellum more finely, punctured, the median callus with a few coarse scattered 
punctures only. Antenne moderately stout, joint 4 a little longer than the others united, 3 longer 
than 2, Pronotum with the lateral angles obliquely truncate; the two dorsal carine converging 
anteriorly and reaching the anterior lobe. Scutellum slightly narrowing from the middle forwards, and 
also narrowing behind, with a raised subpiriform median callus and a smooth median carina, the callus 
extending to a little beyond the basal third and pointed behind. Abdomen oval, the connexivum rather 
narrow and rounded externally. 
Length 64, breadth 23 millim. 
. Broader, less attenuate behind; ochraceous, the head and the basal half of the pronotum mottled with 
fuscous; the scutellum fuscous or brownish, with a faint curved fascia towards the apex, an indistinct 
apical spot, the median callus, and the granules, flavous; the legs slightly suffused with green; the 
apical joint of the antenne shorter and more pointed, scarcely as long as joints 1-3 united; the abdomen 
cordate, with the connexivum much broader; the lateral angles of the pronotum obliquely truncate or very 
feebly emarginate at the tip. 
Length 8, breadth 34-32 millim. 
Hab. Panama, Bugaba, Volcan de Chiriqui (Champion '). 
One male and two females. Differs from Jf. notatus in all its varieties in the truncate 
or very feebly emarginate lateral angles of the pronotum, the much finer puncturing of 
the basal half of the latter, the larger apical joint of the antenne, the relatively shorter 
median callus of the scutellum, and the rounded sides of the connexivum. 
From the allied M. leucographus, Westw., from Haiti, and from MM. westwoodi, Guér., 
from Cuba, it may be known by the pale scutellar callus, and from JZ. westwoodi, in 
addition, by the lateral angles of the pronotum not being raised (fide Handlirsch).

é. Moderately elongate; head black, ochraceous at the sides, the eyes and ocelli ochraceous; pronotum, 
scutellum, and corium nigro-fuscous, the pronotum with the margins (except at the apex of the lateral 
angles) and a narrow median vitta on tbe posterior portion, and the scutellum with a rather broad 
median vitta (including the median carina), ovhraceous; the body beneath, connexiyum, and legs 
ochraceous ; the antenne fusco-ferruginous, the apical joint in great part fuscous; above and beneath, the 
basal joints of the antennw, the coxew and femora, and the two hinder tibize, studded with small smooth 
granules, these being very minute and widely scattered on the pronotum, scutellum, and corium; the 
posterior portion of the pronotum, scutellum, and corium rather closely punctured. Antenna moderately 
stout, joint 4 about twice as long as 2 and 3 united, 3 longer than 2. Pronotum with the lateral angles 
obliquely truncate; the two dorsal carine short and not very distinct, converging in front, and reaching
