412 INSECTA. 



G.dispnr; Cerafopfiyus dispar, Fisch., Entomog. Russ. Imp., 

 II, xviii. A horn on the head and thorax. Italy and Russia. 

 Sometimes both sexes are destitute of horns. They are the Geo- 

 trupes proper. 



G. stercorarius; Scarabseus stercorarius, L. ; Oliv., lb. V, 39. 

 A shining black or deep green above, violaceous or golden green 

 beneath; a tubercle on the vertex; dotted bands on the elytra, 

 with smooth intervals; two indentations at the base of the pos- 

 terior thighs. 



G. vernalis; Scarab, vernalis, L.; Oliv., lb., iv, 23. Shorter 

 than the stercorarius, and approximating to a hemispherical 

 figure; a violet or blue-black; antennae black; elytra smooth. 



OcHODyEus, Meg. — Melolontha, Fab. 



The labrum in this subgenus is strongly emarginated, and almost 

 in the form of a heart truncated posteriorly. The. mandibles are in 

 the form of an elongated triangle, one of them terminating in a sim- 

 ple point, with a notch beneath, and the other in two obtuse teeth. 

 The exterior lobe of the maxillae is bordered with little spines or 

 fftout cilia hooked at the end and has two small horny and equal 

 inner teeth; the other, or internal lobe, is formed by a pointed pencil 

 of hairs. The last joint of their palpi is cylindrical, and much 

 longer than the penultimate; the second of the labial palpi is larger 

 than the others, and the following, or last, in the form of a truncated 

 ovoid. There are but two teeth on the exterior side of the anterior 

 tibiae, and two spines maybe observed on the extremity of the oppo- 

 site side, of which the inferior is the smallest. The body is less 

 elevated, in proportion, than that of the other Geotrupes, and is 

 destitute of horns(l). 



Those Geotrupes, in which the antennal club is large, orbicular or 

 nearly globular, and whose first and last leaflet when contracted 

 completely envelope the intermediate or tenth, or form a sort of 

 box for it, form three subgenera. 'I'hat of 



Athyreus, Mac Leay, 



Approximates to the Coprophagi in its intermediate legs, which 

 are more remote at base than the others(2). 



Elephastomus, Mac Leay. 

 The Elephastomi are remarkable for their epistoma, which is
