also unarmed, and the anterior tarsi are much shorter than in the 
male *; the anterior tibie are externally tridentate, as in the 
Spaastte sex. 
As M. rhinophyllus is the only species hitherto described be- 
longing to the group Mycteristes, I consider my vself very fortunate 
in being epauledl by the ieee of H. Cuming, Esq., to commence 
the present work with a description and figures of both sexes of a 
new species brought by him from the Prahapine Islands. <A pair 
only of this beautiful species were taken, and they are destined for 
the cabinet of the British Museum. From rhinophyllus, however, 
they differ in several respects. The body in the male (fig. 1 and 1 a) 
is shorter, broader at the base of the elytra, which are more flat- 
tened and triangular behind, and destitute of the scales which orna- 
ment rhinophyllus ; the thorax is exceedingly brilliant and polished, 
and the horn at its fore part is much deflexed and strongly notched 
at the tip, with a tubercle within; the horn of the clypeus is also 
furnished with a tubercle in front. The female (fig. 2) is smaller, 
and has the head and thorax unarmed, the elytra flatter, and not so 
triangular. The mesosternum (fig. 1 f) is slightly porrected in 
front. and does not extend lower than the front of the metasternum. 
The parts of the mouth (fig. 1 b, mandible of the female, 1 c, max- 
illa, 1 d, instrumenta labialia of the male, 1 e,-ditte of the female) 
scarcely differ from those of rhinophyllus; the horny, lanceolate 
part of the mandibles is, however, shorter; there appears to me no 
difference between the palpi of the two sexes. The legs of the 
male are larger than those of the female, but the anterior pair are 
not so long as in rhinophyllus, and the fore tarsi are not so long as 
the tibie. All the tibiz in the male are clothed for about half 
their apical portion on the inside with fine hairs. They are all un- 
armed with teeth ; a very slight angular prominence on the outside 
of the four posterior tibiee obscurely indicates the place of the ordi- 
nary teeth. The ungues are particularly large, and between them 
at the base is a very eal plantula, with two very short pseud- 
onychie. The anterior tibize of the female are armed with three teeth, 
and the four posterior with one on the middle, and two at the tip, 
with two ealearia. 
As it has been thought convenient to name the divisions of 
Goliathus proper, which differ in the toothing of the fore legs, the 
present insect may be regarded as a division of Mycteristes, and 
I am indebted to my friend G. R. Waterhouse, Esq., who first 
* In both figures 3 and 4 the fore tarsi are represented scarcely long enough.
