92 Dr. G. B. Longstaff on some bionomic points 
thorax and elytra breaking up the dark ground-colour and 
simulating the general look of the anthers of the flower. 
Another small Cetoniid, Stringophorus flavipennis, G. and 
P., occurred on the same flowers and its elytra bear similar 
spots. Together with these were two specimens of a third 
and still smaller Cetoniid, Comythovalgus fasciculatus, 
Schénh., which were quite difficult to distinguish, but in 
this case the means of concealment was different, for the 
thorax and elytra bear numerous conical, horny projections, 
while there are two conical tufts of scales near the apex 
of the abdomen. 
Two larger species, Rhabdotis (Pachnoda) sobrina, G. 
and P., dark olive-brown and white, and Aacroma cognata, 
Schonh., dark chocolate-brown and canary-yellow, both 
seemed conspicuous enough, the one at the sweet white 
flowers of Dombcia, the other on the wing, but I strongly 
suspect that in their case too, when on an appropriate 
background the breaking up of the dark colour by light 
markings aids concealment. 
With Gametts balteata, De G., the case is different. This 
beetle is black and red, or perhaps orange-brown more 
correctly describes its decoration. At East London, on one 
of the tributaries of the Buffalo River, there grows a profu- 
sion of a climbing composite with greenish-white flowers, a 
plant in general habit and appearance very suggestive of 
Clematis vitalba, L. On one of these plants I took a 
number of specimens of two species of Haplolycus, which 
are represented in the National Collection but as yet 
unnamed. These Malacoderms have the usual Lycus 
coloration, viz. orange-brown with the apical two-fifths 
of the elytra black, and a black stripe down the middle of 
the thorax. On the same day, on another bush of the 
same climbing composite growing a hundred yards higher 
up the stream, I took an example of Gametis balteata, De 
G., and was at once struck by the striking resemblance of 
the two insects. JI may remind any Fellows who are not 
familiar with living specimens of beetles of the Zycus group, 
that during life the orange-brown colour is much redder 
than might be supposed from cabinet specimens, whereas 
the Cetoniid preserves its colour well. 
The very next day Dr. Dixey saw both these beetles in 
some numbers (3 Haplolycus and 8 Gametis) in the Queen’s 
Park on and about a flowering tree and noted their simi- 
larity. With them were two specimens of a Lycoid-coloured
