beneath, and the mesosternum is porrected, conical, and acute, but 
rather broader at the base than in the male. 
The differences between this genus and the true Goliathi consist 
in the sides, and not the centre, of the clypeus being comuted; 
the armature of the fore tibiae in the males, the different form 
of the mentum, maxillae, and pronotum, and the cornuted head of 
the female. 
It is to the genus Narycius, but forming a subgenus distinct 
from the type, that I refer a new and beautiful unique insect 
which has been communicated to me by that assiduous entomolo¬ 
gist G. H. K. Thwaites, Esq., of Bristol, whilst this sheet is pass¬ 
ing through the press (14th June, 1842), on which account the 
figures in illustration of it will not appear until the following num¬ 
ber is published. 
NARYCIUS, subgenus CYPHONOCEP1IALUS, I Vestw. 
CHARACTERES EX IND1VIDUO MASCULINO DESUMPTI. 
Corpus suhlatum, caput breve, transversum, supra semicirculariter excavatum, clypeo piano 
valde deflexo, capitis lateribus in cornua duo elongata elevata apice curvata et postice 
furcata, productis (plate 33, fig. 2 a , caput supra, 2 b 9 e latere, 2 c, antice visum); anten¬ 
na™ 111 clava subelongata. Maxillae (fig. 2*/) lobo intemo ad apicem in dentem acutuni 
producto; lobo externo curvato, apice 3-dentato. Mentum (fig. 2e) latum amice 
angustatum, margine antico valde inciso. Pronotum latum, valde gibbosum, margine 
antico supra caput rotundato, angulis anticis rotundatis; lateribus pone medium fere 
ad angulos posticos parallels ; elytra vix pronoto latiora, versus apicem parum angustata. 
Pedes antici subelotlgati, tibiis inermibus, tarsis tibiis brevioribus ; nnguibus maximis, 
onychiis distinctis (fig. 2/s); tibiae 4 postiem medio inermes; mesosternum subconicum 
porrectum (fig. 2f 2 g) ; abdomen valde canaliculatum. 
In the more important of these characters the insect approaches 
the typical Narycius, differing chiefly in the form of the liorns of the 
head and fore legs; whilst in the sub-elongated fore legs, and especially 
in the form of the horns of the head, it bears a nearer resemblance 
to Dicronoceplialus; from which, however, the structure of the 
maxillae, mesosternum, and anterior tibiae, and its beautiful emerald 
colour, remove it.
