THE EUDKMA. 55 



In point of colour, the two handsomest of the group are 

 natives of Bolivia, and by far the finest of them is Bracliygnathus 

 oxygonus. It is not half the size of the Tefflus, but is a most 

 resplendent insect, its thorax being polished, shining blue, 

 glossed with intense yellow, especially at the edges. The elytra 

 are covered with parallel longitudinal grooves, very deeply cut 

 and slightly punctured, and are reddish bronze, changing into 

 green when the light falls obliquely on them. Another 

 remarkable characteristic of this insect is the shape of the 

 thorax, which is flattened above, and the two hinder angles 

 lengthened into sharp points. The head is very small, and the 

 shape of the head and thorax together is very much like that of 

 a deeply barbed spear-head. The jaws are small in proportion 

 to the head, thus giving rise to the generic name Bracliygnathus, 

 i.e. " short-jawed." The specific name, oxygonus, or " sharp- 

 angled," refers to the peculiar shape of the thorax. 



The second brilliant species is Bracliygnathus pyroptcrus, a 

 Beetle coloured in a similar manner, though not so brightly, and 

 not possessing the pointed angles of the thorax so proportion- 

 ately long. The specific name, pyroptcrus, or "fire-wing," refers 

 to the fiery-red bronze of the elytra. 



Another species of this group is the East Indian Eud&ma 

 tomcntosus, which is shown in the accompanying illustration. 



This is really a pretty, though not brilliantly coloured insect, 

 attracting the attention of the 

 entomologist by the strong like- 

 ness to its little British relative, 

 Panagams punctatus. The head 

 and thorax are black, and so are 

 the elytra, except that near the 

 shoulder and tip of each elytron

there is a large yellow- spot, (Black and yellow . , iairy) 



which gives to the Beetle a look 



as if it were yellow, with a large black cross drawn upon it. 

 The elytra are boldly ridged and very finely punctured, and the 

 whole body and limbs are covered with very minute black hairs, 

 which extend even to the tips of the antennas. 



The generic name, Eudema (the " e " being short), signifies 

 " beautifully banded," and the specific name, tomcntosus, signifies
