Elephastomus, Macl. 



Are remarkable by the chaperon dilated on each side, and 

 prolonged forward in their middle into a sub-quadrangular 

 lamina, thicker and forked at the end, and moreover by the 

 length of the maxillary palpi, which is nearly three times 

 that of the labial. The chin is deeply emarginated, and the 

 two mandibles are indented at their extremity, Horae

In which, as in Ochodaeus, to which they approximate 

 closely, one of the mandibles is simple, and the other biden- 

 ticulated at the end ; the maxillary palpi are scarcely larger 

 than the labial, and the chin has no emargination. 



We have one species in France, S. mobilicornis. Fab. 

 Panz. Faun. Insect. Germ. xii. 2. It is small, black above, 

 yellow underneath, with a very long horn, linear, slightly 

 bent back, and moveable on the head. The corslet is deeply 

 punctuated, channeled in the middle, with four tubercles in 

 front. The elytra have punctated striae. The body is 

 sometimes entirely yellow. (S. testaceus, Fab.) 



One of the sons of the celebrated traveller and ornitholo- 

 gist, Le Vaillant, has remarked that frogs and toads were very 

 fond of this insect, and he has obtained a great number of 

 them from the stomachs of these reptiles. 



Our first division of Arenicolous Scarabaei terminates with 

 those whose antennae, as in most of the following scarabaei, 

 have ten articulations.
