CLASS INSECTA. 



ated stripes on the elytra, the intervals smooth, two denticu- 

 lations at the base of the posterior thighs. 



G. vernalis, S. vernalis, Lin. Oliv. Col. iv. 23, shorter 

 than the preceding, approaching the hemispherical form, of 

 a violet or blue black, with the antennae black, and the elytra 

 smooth. 



OcHOD.EUs, Meg. Mehlonthay Fab.* 



Have the labrum strongly emarginated and nearly in the 

 form of a heart truncated posteriorly ; the mandibles are in 

 the form of an elongated triangle, one of which terminates 

 in a single point, with a notch underneath, and the other in 

 two obtuse teeth ; the exterior lobe of the jaws is edged with 

 small spines or large cilias, bent at the end, with two internal 

 small corneous and equal teeth ; the other, or internal lobe, 

 formed of a pencil of silk brought to a point ; the last arti- 

 culation of the palpi is much larger than the preceding, and 

 is cylindrical ; the second of the labial palpi is larger than 

 the others, and the following or last is a truncated ovoid. 

 The fore legs have only two teeth on the outer side, and the 

 end of the opposite side two spines, the lowest being the 

 smallest. The body is in proportion less elevated than that 

 of the other geotrupes, and without horns. 



The Geotrupes — with a knob to the antennae, large, 

 orbicular, and nearly globular, the first and last laminae 

 of which entirely cover, when contracted, the intermediate 

 or tenth, or form for it a sort of case — compose three other 

 sub-genera.
