140 INSECTS ABIJOAD. 



paratively gia.nts. Still, though the Ehamphorhinas do belong 

 to the Goliaths, none of them are very large ; their brilliancy ot 

 colour, however, compensating for their lack of dimensions. 



At first sight this Beetle gives the observer the idea that it is 

 made of the most brilliant green porcelain, and, indeed, it almost 

 looks as if it were artificial rather than a real insect. The oddly- 

 formed head is flattened and rather scooped, and in the male is 

 deeply toothed in front, and furnished with a sharp curving horn 

 on either side, shaped very much like the well-known horn of 

 the chamois. The head is white, and the horns are black. The 

 head of the female is much smaller, entirely without horns, and 

 almost entirely without the teeth on the front edge. 



The thorax is rounded, very highly polished, and of the most 

 vivid emerald green, with a sort of translucent effect about it, so 

 that it looks very much as if it were made of the finest porcelain 

 or enamel. The elytra are of a similar green, except that upon 

 them is drawn a large white mark, the shape of which can be 

 seen by reference to the figure. The legs are long in proportion 

 to the size of the body, and the first pair are very much 

 developed, and bear on the under side of the tarsus a bunch of 

 long, golden yellow hair. 



If the insect be turned over, the under surface is seen to be 

 quite as beautiful as the upper, though in a different way. The 

 under side of the head, instead of being white, is rich chestnut 

 red, and the general colour of the body is bronze, with a porce- 

 lain-like surface, much like that of the thorax and elytra, though 

 not so brilliant. One very curious point about this Beetle is the 

 longitudinal projection between the middle and last pair of legs. 

 This projection is pear-shaped, lies on the central line of the 

 body, and is of an opaline green. It seems to have an analogy 

 with the sharply-pointed projection in the Dyticus and other 

 Water Beetles, though no one appears to have discovered its 

 object. 



The length of the specimen from which this description was 

 taken is one inch and three -eighths. The female, besides being 

 unarmed, is much duller in colour, and does not possess the 

 peculiar porcelain or enamel-like surface which distinguishes 

 the other sex. The length of a fine specimen is nearly an inch 

 and a half. 



The habits of the Goliath Beetles are very much like those of
