CORNUTED CETONIIDA, 9) 
directed my attention to this interesting novelty, for the following 
description and name :— 
MYCTERISTES (PHAEDIMUS) CUMINGII. 
M. viridis, nitore resplendens, elytris pedibus et corpore subtus flavesceite 
lavatis, corpore subtus paullo pubescente ; capite cornu erectum exhibente (hoc 
quoad caput longitudinem equante) ad apicem latum et paullo emarginatum, 
postice concavum, antice tuberculo uno ohsitum ; thorace convexo postice augus- 
tiore quam ad mediam, marginibus lateralibus pone mediam fere rectis, antice con- 
stricto, margine posteriore in medio paullo producto, antice porrecto in cornu validum 
ad apicem bifidum super caput impendente ; scutello mediocri triangulari, elytris 
longioribus quam latis, postice attenuatis, disco plano, apice subtruncato ; pedibus 
validis, tibiis scopula pilorum subtus instructis et externe haud denticulatis, tarsis 
quam tibiez paullo brevioribus, unguibus permagnis. ¢ Long. corp. lin 12}, 
Differt foemina corpore minore capite thoraceque haud cornutis, pedibus medio- 
cribus, tibiis anticis externe tridentatis, reliquis denticulo externo parvo infra 
medium instructis, unguibus mediocribus. Elytra in foemina quasi flavescentia 
aureo-viridi lavata apparent, sutura et linea longitudinali prope marginem intense 
viridibus. 
In the two species above described, the middle of the front of 
the head is produced into a single upright horn; but in the two 
other species figured in plate 1, each side of the clypeus, or front 
of the head, is produced into a horn, giving the insects a greater 
resemblance to certain cornuted quadrupeds. 
Dicranocephalus Wallichii (fig. 4) is an exceedingly rare insect, 
first brought to Europe from Nepaul by the late Major-General 
Hardwicke, and shortly characterised by the Rev. F. W. Hope in 
Gray's Zoological Miscellany (1831, p. 24). The male is well 
figured in Gory and Perchéron’s Monographie des Cétoines, tab. 
26, fig. 1, under the name of Goliathus Wellech. The specimen, 
however, which they figure, has the horns of the head of small size ; 
whilst in those of the fine specimen represented in my plate (pre- 
served in the Cabinet of the British Museum), they are very 
greatly elongated and recurved *. The parts of the mouth are 
represented in figures 4a (one of the mandibles), 4b (one of the 
maxille), 4¢ (instrumenta labialia), and 4d (labrum). The meso- 
sternum (fig. 4e) is prominent but deflexed, extending lower than 
the front part of the metasternum. 
The female has the fore tibize spined, as in the male; and the 
head, instead of being cornuted, has each of the front angles pro- 
duced into a tooth. 
The outline, fig. 5, represents the Narycius opalus of Dupont, a 
species from Madras, of which I believe no specimen exists in this 
country ; figured in Guérin’s Magazin de Zoologie, Insectes, pl. 128 : 
* This specimen affords another instance of the great development of the horns in certain 
individuals of cornuted species, which are almost invariably (as in this instance) of larger size 
than the ordinary individuals.
