570 SUPPLEMENT, &C. 



The most common species, and which is to be met with from 

 the earliest days of spring, is the opatrum sabulosum. Fab. ; 

 silpha sahlosa, Linn. 



The opatra are extended into all parts of the world ; but 

 in a greater number in the Ancient Continent. Olivier has 

 described thirty-four species of them. 



The only species known of the genus Orthocerus, and 

 which had been placed in various genera, is evidently con- 

 nected from its habits with the opatra, and from its elongated 

 form, as well as the parts of its mouth, with tenebrio. 



This insect is winged. It is found in spring in dry and 

 arid places, and in sand-pits. It walks slowly, and when it 

 remains tranquil it is distinguished with difficulty ; either 

 because its colour is the same as that of the soil on which it 

 remains, or on account of its littleness.
