What the ZH. suturalis of Klug really is I do not know; the locality “ America 
borealis ”? is very vague. Whether the species Spinola figures under this name [Atlas, 
t. 39. f. 6], but which he described as H. limbata, is the same species is to me extremely 
doubtful; but however that may be, the insect found by Mr. Champion on the 
Volcan de Chiriqui at from 4000 to 6000 feet elevation is certainly distinct from 
H. marginata. ‘The head is narrower between the eyes, and entirely black, excepting 
the mouth. ‘The thorax is narrower, and is black with the front margin and three 
lines yellow. The elytra are narrow, serrate at their apex, with two small distinct 
teeth, the suture black, more widely so at the base, their margin blackish, but not so 
at the base; the shoulder is not tipped with black ; and they are more thickly and 
more coarsely punctate. The legs are yellow, the femora only just touched with 
fuscous. a 
About nine specimens from the Volcan de Chiriqui agree very closely with: the one 
previously recorded from Boquete. | 
14 (a). Hydnocera furcata. (Tab. XIII. fig. 14.) 
Fusco-cinerea, sat dense pubescens, eeneo-micans, creberrime punctata; elytris macula magna circa scutellum 
alteraque minore mediana albidis, dense cinereo-tomentosis ; antennis, geniculis, tibiis tarsisque, obscure 
testaceis. Long. 43-6 millim. 
Mas? Abdominis apice mucrone duplici exstante. 
Hab. Mexico, Northern Sonora (Morrison). 
Of the form and not unlike H. obscura, but with the puncturing of the elytra very 
much more close and intricate, resembling in this respect H. scabra and its allies; it is 
also nearly allied to H. rudis, but easily distinguished therefrom by the white markings ; 
these in this species nearly unite, and indeed appear united in fresh specimens owing 
to the extension of the ashy, shining hairs. The curious processes from the subapical 
segment of the abdomen are, I think, peculiar to this species; at all events nothing of 
the kind has been recorded in any other species. 
Ten or twelve examples sent us by the late Mr. Morrison. 
14 (8). Hydnocera rudis. 
Fusca, dense pubescens, zneo-micans ; antennis (apice excepto) testaceis, genibus tarsisque anticis rufis; elytris 
fasciculis duobus scutelloque albido-sericantibus. Long. 44-6 millim. 
Hab. Mexico, Northern Sonora (Morrison). 
Head wide; thorax narrower, quadrate, a little narrowed behind, without the sides 
being much swollen; both densely and granulosely punctate, grey, with a bright metallic 
lustre, clothed with black upright pile, and ashy depressed hairs, not regularly but 
“combed” in all directions; elytra similarly clothed, but the pile disappears towards 
their apex, the latter not crenulate. Underside brassy ; legs with long hairs, dark 
ashy-grey, except the front pair, of which the tibie and tarsi are rufous, but dark in
