258 On new African Cetoniide. 
Hab. MASHONALAND, Salisbury. 
The rotund form of this insect with its short, evidently 
fossorial, legs and clothing of hairs and sete give it an aspect 
farther removed from that characteristic of its family than is 
shown by any other member of the group known tome. The 
head, with the mouth-organs, and the under surface of the body 
are almost as in the genus Myoderma, but there is no produc- 
tion of the mesosternum. There is no flattening of the upper 
surface, which is uniformly finely rugose and clothed with 
very short golden sete. ‘The sutural margins of the elytra 
are strongly raised and there are four other narrow coste, 
sometimes hardly traceable. The pygidium and under surface 
are red and densely hairy. The legs are very short, with 
strong spiny tibie and thread-like tarsi, and the front tibia 
have two strong spatulate teeth. The whole structure 
unmistakably indicates a burrowing habit, but nothing is at 
present known as to the insect’s manner of life. ‘The speci- 
mens collected by Mr. Marshall were found on the wing at 
dusk in the month of November. They include both sexes, 
which do not differ externally. 
The following new species of the allied genus Myoderma 
may be conveniently described here :— 
Myoderma nigra, sp. n. 
Nigra, nitida, depressa, clypeo quadrato, margine elevato, medio paulo 
lobato; prothorace crebre et grosse punctato, lateribus postice 
rectis, ante medium valde angulatis et retractis, angulis posticis 
fere acutis, margine postico lobato; scutello medio punctato ; 
elytris subtiliter sat crebre punctatis, striatis, intervallis convexis, 
striis quarto et quinto postice abbreviatis, lateribus parum curvatis, 
apicibus ad suturam obtuse angulatis ; pygidio corporeque subtus 
fusco-hirtis, pedibus concoloribus, tibiis anticis obtuse tridentatis, 
posticis quatuor medio tuberculatis ; mesosterno paulo producto, 
antice rectangulari. 
Long. 17 mm. 
Hab. W. A¥rica, Mt. Cameroons. 
Two male specimens of this insect were found by Sir H. 
H. Johnston in 1886 at an altitude of 8000-10,000 feet upon 
the Cameroons Mountain. It differs from all other known 
species of the genus by its uniform black colour and the 
configuration of the surface of its elytra. The latter do not 
exhibit rather widely separated ridges, as is usually the case, 
the intervals which separate the latter beimg in M. nigra 
themselves elevated so that the whole surface is broken up
