it is another groove equally profound ; posterior angles obliquely 

 truncated : elytra with the fascicles of yellow hair, on the ele- 

 vated lines, rounded and not oblong, equal ; interstitial spaces 

 with small tubercles. 



Length nearly one-fourth of an inch. 



This insect is about equal in size to the arenarms Fabr., from 

 which it differs in having no capillary lines in the interstitial 

 spaces of the elytra. The van'olahis of Mclsh. Catal. if not alto- 

 gether the same as the arenarhis of Europe, is certainly most 

 closely allied to it. 



3. T. PORCATUS. — Elytra with elevated interrupted lines and 

 numerous transverse punctures on the interstitial spaces. 



Trox porcdtHs Melsh. Catal. 



Body brownish-black : head somewhat inequal, with a more 

 distinct frontal groove : thorax with short brownish hair ; a deep 

 and well defined longitudinal groove, sides inequal ; lateral edge 

 entire; posterior angles projecting: elytra with regular series of 

 interrupted hairy lines, the series alternately smaller ; interstitial 

 spaces with dilated transverse impressed distinct punctures. 



Length nearly nine-twentieths of an inch. 



A little larger than canalicidatus nobis, which it resembles, 

 but it differs in having the transverse punctures of the elytra ; 

 cajnlldvist nobis is smaller than the above-mentioned species, and 

 may be distinguished from the present by the capillary lines of 

 its elytra. [194] 



SCARAB^US Latr. 



S. RELTCTUS. — Head with an elevated transverse line, inter- 

 rupted in the middle; clypcus at tip elevated and bidentate. 



]5ody browni.sh-black : head with a transverse elevated line 

 between the origin of the antennae, interrupted in the middle, 

 and most prominent near the interrupted part ; tip of the clypeus 

 with two reflected, acute denticiilations : thorax with rather 

 sparse punctures : elytra punctured, and with three double series 

 of punctures, ttinverging towards the apical angle; the second 

 and third double series do not reach the angle, a fourth double 

 series is on the exterior submargin, but is not so distinct as the 

 t>t]iors : beneath piceous : pectus and postpectus hairy: feet 

 above blackish : venter blackish.
