A NEW GENUS OF GANOID FISH. 475 



fly ; and although some of them were caught in fish traps, which are stated to 

 have been baited with palm nuts, it must have been simply from curiosity that 

 the fish poked into them, and were taken ; or perhaps the palm nuts might 

 attract insects and their larvae, in the water, and the fish, following in pursuit, 

 be in this way decoyed into the trap, and captured. 



The insects found in the stomach of the fish belonged, as far as was noticed 

 — for the more perfectly preserved insects alone were examined — to the abundant 

 African family of the Termitidm, the Termites, or white ants, as they have been 

 designated. These insects were found under all their stages or transformations. 



1. Eighteen specimens of labourers or larvae were collected. These measured 

 each I of an inch in length. The head is whitish, but the jaws are tipped with 

 blackish or brown colour, and are horn-like in their appearance. The thorax and 

 legs are white; the abdomen is rounded, the dark-coloured viscera or their con- 

 tents shining through the white and semi-transparent skin. No eyes were visible. 



2. One specimen only of a soldier Termite was seen ; it was -$j of an inch in 

 length. The body is white, but the contained viscera show black, like the last, 

 through its semi-transparent skin. The thorax is white. The head is large, 

 square in front, and rounded behind ; it is larger in size than the abdomen, and 

 is reddish in colour especially in front, and horny-like in structure, with two 

 black scimitar-like projecting jaws. No eyes were visible. 



3. Six specimens of pupce were also noticed ; their bodies are entirely of a 

 pale yellowish white colour, and seem to be of rather a soft consistence; 

 the eyes, however, are now present in the form of minute black specks, distinctly 

 visible. The abdomen is large and full. Four flattened lobes — the projecting 

 wings — pass backwards from the thorax ; they are very distinct, but do not extend 

 backwards as far as the posterior extremity of the body, the wings being apparently 

 folded upon themselves from below upwards, at about the middle of their length. 

 The pupae measure each about ¥ V 0I> an i ncn m length. 



4. Five- winged and perfect insects, or Termites, were examined. Their bodies 

 are generally dark-brown in colour, with four long narrow and blackish- 

 coloured semi-transparent wings, nearly equal in length, with black nervures, the 

 costal and sub-costal are robust and unbranched, the other nervures being finer, 

 and branching over the rest of the wing. (In the specimen figured below, the 

 nerve next the subcostal varies in the arrangement of its branches in each of the 

 upper wings, probably an accidental peculiarity.) The wings extend considerably 

 (/o of an inch) beyond the body, the total length of the insect to the extremities 

 of the wings being -i-J- of an inch, and that of the entire body \. The head and 

 upper parts of the thorax are dark-brown, the legs lighter; the stemmata are 

 immediately in front of, and slightly below, the eye on each side, and a little in 

 front and above the origin of the antennae, and no central point was observed ; 

 the abdomen on its upper surface has ten segments or plates of a dark colour
