Habitat ; Penang. (D. Lamb.)
The prothorax is subbeptagonal, the fore margin nearly straight, the lateral margins slightly angular in
the middle, and the liind angles obtuse ; the hind margin is slightly produced in the middle. The scutellum is
one-third of the length of the elytra. The elytra are twice the length of the prothorax. They have a stria on
each^ side of the suture, and another (anteriorly abbreviated) at the end of the inner red patch. Between the
two red patches, which are very convex, glossy, and almost impunetate, there arise four plain striaj, between
which and the lateral margins are several very irregular rows of punctures. Beneath, the body is black, glossy,
and slightly puncturetl ; the coxas of the fore legs are clothed with fulvous hairs, the hind cox® are striolatevermiculate;
the three basal segments of the abdomen have a transverse fascia of luteous scales, interrupted
in the middle ; the hmd femora are obliquely striolated.

Habitat; Old Calabar. In Mus. Hopeiano Oxonise.
The dissections accompanying the figure of this species are taken from the unique specimen of the male in
the Hopeian Collection. The mandibles (lig. 3 a) have the upper edge of the basal portion and the outer edge
of the horny knife-like external part setose. The maxillas (fig. 3 i) have the upper edge of the flat square
mando and the galea densely clothed with long hairs; the mentum (fig. 3 c) is obconical, notched on each side
below the anterior rounded angles, for the rcecption of the palpi; the anterior margin is widely but not very
deeply emarginate. The markings on the upper surface of the body are produced by squamosity, and are not
at all clearly defined. The legs are long and slender, the fore tibias have two sharp teeth at the extremity, and
a third much shorter between the base and the middle; the middle tibiae are rather short and much curved,
and the hind tibia? are long and straight; the tarsi are long and slender. The pro- and meso-sterna are simple
and unarmed, the mesosternum being obliquely obtuse.

This group, by means of such genera as Uloptera and Macroma, is related to the more typical Cetoniidfe,
through such genera as Diplognathus and Auoploclieilus, with which indeed Mr. MacLeay united the more
aberrant Cremastoeheilides (in his memoii- on the South African Cetoniidie); whilst the more typical Cremastocheilides
were formed into a separate group, Cryptodinus, with Cryptodus as the leading genus. This lastnamed
genus however, as I proved by careful analysis in a memoir published in the fourth volume of the
Transactions of the Entomological Society of London (1845-1847), belongs to the DynastidEe, and is in no -wise
related to the Cremastoeheilides except in the obscure colours and flattened form of the species. In the Berlin
Museum another Dynastideous genus is also arranged with these insects—Cryptodontes Dej. Eurm. (Leptognathus
Westw.)—the anatomical details of which I have also elucidated in the same memoir.
But very little is known of the habits of the insects of this family. Dr. Schaum found one specimen
of Cremasiocheikis canalicitlaius in the nest of a large black species of ants on the Catskill Mountains ; and
Professor Haldcman, in Pcnnslyvania, found several specimens of two species in ants' nests. Herr Guienzius
found Ccemchilus selosus in ants' nests, the individuals being covered with the ants, which seemed to suck
from them a gumnjy exudation. He also discovered Scaptobiiis aoicidatus in ants' nests, in company with
Vmissus nicullalusj also specimens of Lissogcnius were found by him in similar situations.
