398 INSECTA. 



This tribe is composed of the genus 



CossYPHus, Oliv. Fab. 

 Some of them have a flat body, of a solid consistence, in the form of a shield, 

 and antennae terminated by a club composed of four or five joints; they are 

 peculiar to the eastern continent and* to New Holland. Such are those 

 which form the 



CossTPHus, Oliv. Fab. 



Or Cossyphus properly so called, where the almost semicircular thorax 

 presents no anterior emargination, and entirely conceals the head; where 

 the antennae are short, and terminate abruptly in an oval mass of four joints, 

 most of which are transversal; the second of the whole number and the 

 following- ones are almost identical. 



These Insects inhabit the East Indies, southern part of Europe, and north 

 of Africa. 



FAMILY III. 



STENELYTRA.(1) 



The third family ofheteromerous Coleoptera only differs from the 

 second in the antennae, which are neither granose nor perfoliate, and 

 whose extremity, in the greater number, is not thickened. The 

 body is most frequently oblong, and arcuated above, and the legs 

 are elongated as in many other Insects. With the exception of their 

 antennae and size, the males resemble the females. These Hetero- 

 mera are usually much more agile than the preceding ones; several 

 conceal themselves under the bark of old trees, while most of the 

 others are found on leaves and flowers. 



In some, the antennae are approximated to the eyes, and the head 

 is not prolonged in the manner of a proboscis, but terminated at 

 most by a very short snout. They will form our four first tribes. 



Those of the first or the Helopii, have their antennas covered at 

 base by the margin of the head; they are generally filiform or slightly 

 thickened towards the extremity, generally composed of almost cy- 

 lindrical joints attenuated at base, of which the penultimate ones 

 are frequently a little shorter, and in the form of a reversed cone, 

 and the last is usually almost ovoid; the third is always elongated.
