are sometimes faintly suffused, and the hind tarsi are blackish. 
The body beneath is bluish. The extraordinary structure of the 
head in the male is alone sufficient to distinguish this insect from 
any species described ; it resembles in colour and size an insect 
sent by Mr. G. A. K. Marshall from Salisbury, and which I 
doubtfully referred to H. variicornis Bohem., but as the latter 
Specimen was a male I am certain that it does not belong to the 
species I now describe. 
Obs.—Boheman does not in describing H. superciliosus give the 
diagnosis of the male head, but I have no doubt from his remarks 
it is a male he describes. His express assertion, repeated, that 
the scutellum is yellow precludes any of the specimens I have yet 
received from being referred to this species. A considerable series 
of this insect has been obtained by Dr. Brauns; four males and 
four females are before me.

One male and three females, in all respects agreeing with the 
types. They are interesting as corroborating the differences 
pointed out before and as being found in quite a new locality. 
PuiLHEDONUS Gorham. 
Phithedonus Gorham, Ann. & Mag. N. H. ser. 7, v. p. 82 (1900). 
PHILHEDONUS SERICEUS, Sp. n. 
Vigro-ceruleus, pube brevi sericea vestitus ; prothorace rufo, fere 
glabro, macula nigra in margine antico haud bene discreta ; 
elytris creberrime subtiliter punctatis, pube brevi pruinosis ; 
scutello, pedibus et corpore infra nigro-ceruleis. Long.

Hab. Bothaville, Orange R. Colony (Lrauns). 
This Philhedonus differs from the insect described by me as 
P. coronatus by its smaller size, by the wholly black antenne, 
and by the labrum not being red; the thorax is also differently 
marked, the single black spot is placed upon the front margin, and 
is wedge-shaped, pointing backwards. The head is blue-black and 
shining, not punctured, very sparingly golden pubescent; antenne, 
mouth, and palpi black, the former short and feebly serrate. The 
thorax is wider than long, the sides and base finely margined, 
the anterior margin raised, but only very finely so. 
The elytra are wide, and are widest a little before the apex, 
deep blue with a silky and shining pubescence ; the punctuation 
is fine, close, and confluent. They do not cover the apex of the 
abdomen. ‘The body and legs are entirely blue-black ; the vesicles, 
which can be protruded from the sides (and are so in the 
specimens sent), are blood-red. The pygidial segments beyond 
the elytra show a green tinge. The examples, two in number, are 
both, I think, females.
