122 ASIATIC CETONIIDA. 
Sprecies I11.—Trigonophorus Saundersii, Westw. {Plate 29, fig. 5). Tr. aureo-viridis, 
elytris tenuissime rugosulis et punctatis, cornu frontali capitis brevi trigono ; postico acuto, 
4, truncato, 2 5 capite et abdomine subtus pedibusque brunneo-castaneis, metathorace 
subtus viridi. Long. corp. lin. 12. Habitat in India Orientali. In Mus. D. Saunders et 
Mere. Ind. Orient. Londini. 
This is smaller than any of the other species, and is distinguished 
from Tr. Nepalensis by the much shorter horn at the front of the 
head; the upper surface of the head is olivaceous green and punc- 
tured, the angles in front of the eyes forming obtuse elevated 
tubercles, instead of being acute as in Tr. Nepalensis; the hind 
horn of the head is nearly flat, broad, and truncated in front in the 
female, but acute in the males ; the sides of the pronotum are much 
more thickly punctured than the dise ; the elytra are more strongly 
punctate than in Tr. Nepalensis, with the disc slightly rugose, 
giving it a silky appearance according to the play of light. The 
podex is green. The legs, as well as the underside of the head and 
abdomen, are of a rich marroon colour, the fore feet bemg formed 
as in the other species. The tarsi are black. The mesosternum 
is long, narrow, porrected, and bent rather downwards. The hairs 
on the hind feet and sides of the abdomen are few in number, thin 
and dark-coloured; the entire metasternum is green, forming a 
strong contrast with the rich colour of the other parts of the under- 
side of the body. 
Specirs [V.— T'rigonophorus Delessertii. (Plate 30, fig. 4). 
Syn.—Goliathus Delessertii, Guérin. Révue Zoologique par la Soc. Cuvier., 1839, 
No. 8, p. 229. 
This magnificent species was kindly sent to me from Paris by 
M. Guérin Meneville, for illustration in this work. The detailed 
description will be found in the Révue Zoologique, above referred 
to;—a work containing descriptions of a vast number of new species 
of insects, as well as notices of many works of Entomology, which 
are almost unknown to English Entomologists. The species was 
found upon the plateau of the Neilgherries near Otacamund and 
Kotirghery, by the zealous traveller in honour of whom it has been 
named. M. Guérin describes the posterior horn of the head as 
being “‘ plate, dirigée en avant et en bas, aplatie ;” not noticing its 
triangular shape, which is most singular, when it is considered that 
the insect is a female, and that the females of the other species of 
the genus have this horn truncate. 
The plants figured in Plates 29 and 30 are two fine species of Cypripedium ; that in the 
former Plate being C. venustum, (a native of Nepaul) drawn from a specimen which blos- 
somed finely in the Botanic Gardens at Kew, at the beginning of the present year; and Plate 
30, representing the Indian Cyp. insigne.
