Athyreus, Mac Leatj, 



Approximates to the Coprophagi in its intermediate legs, which 

 are more remote at base than the others *. 



Elephastomus, Mac Leay. 



The Elephastomi are remarkable for their epistoma, which is 

 dilated on both sides and prolonged anteriorly, in their middle, 

 in an almost square lamina, thickest and forked at the end ; and 

 for the length of their maxillary palpi, which is almost thrice that 

 of those attached to the labium. The mentiim is profoundly emar- 

 ginated, and the mandibles are dentated at the extremity f.

 Where, as in Ochodaeus, to which they closely approximate, 

 one of the mandibles is simple at the extremity, and the other den- 

 tated. The maxillary palpi are not much longer than the others, 

 and there is no emargination in the mentum,

 Insect. Germ., XII, 2. Small ; black above, fulvous beneath ; 

 the head armed with a very long, linear, slightly recurved and 

 mobile hom ; the thorax deeply punctured, canaliculated in the 

 middle, and furnished anteriorly with four tubercles ; elytra 



marked with dotted strice ; the body sometimes all fulvous S. 



testaceus. Fab. Found in France. 

 One of the sons of that celebrated traveller and X)rnithologist, Le 

 Vaillant, observing that Frogs and Toads are excessively fond of 

 this Insect, procured numerous specimens by eviscerating those Rep- 

 tiles +. 



Our first division of the Scarabaeides Arenicoli is terminated by 

 those in Avhich the antennae, as in the most of the subsequent Sca- 

 rabaeides, are composed of ten joints. 



The last joint of their palpi is elongated. The maxillary lobes 

 are membranous. The labrum is less salient than in the preceding, 

 or projects but little. The mandibles are not at all or but very 

 slightly dentated. The epistoma is short, either arcuated and round- 

 ed, or projecting into an angle. They are very small Insects, whose 

 thorax is destitute of horns.
