274 SUPPLEMENT ON THE CARNIVOROUS FAMILY 



We will add a new species of pasimachus, which we name 

 Mexicanus. It is dark green, with the margins lighter, the 

 thorax rather cordiform, with the antennae, legs and mandi- 

 bles, black. The length is eleven lines and a half ; it is an 

 inhabitant of Mexico. In the collection of Mr. Hope. 



After Ozcena of Olivier, Ave have established a new genus, 

 to which it is nearly allied, under the name of Goniotropis ; 

 it has the upper lip short, transverse, with a row of hairs 

 near the interior margins ; mandibles strong, dentated ; the 

 maxillary palpi with the last joint cylindrical, truncate ; the 

 last joint of the labial palpi is subsecuriform, the mentum 

 with the margination in the middle slightly produced, and the 

 antennae the length of the head and thorax, hirsute, monili- 

 form, with the last joint acute, with the anterior femora and 

 tebia strongly toothed ; the thorax subcordiform ; the elytra 

 with a hook at each angle. The species is from Brazil, there- 

 fore we name it Braziliensis. It is piceous, black, shining, 

 delicately punctated, the tarsi and suture of the elytra piceous. 

 The length is nine lines. In the collection of J. G. Chil- 

 dren, Esq. 



In DiTOMUs, to which M. Ziegler, a very distinguished 

 German entomologist, gives the name Aristus, the body is 

 elongated and depressed, and separated into two parts, by a 

 remarkable strangulation, which divides the corslet from the 

 abdomen. Their antennae are filiform, tolerably long, with the 

 second articulation shorter than the third. The head is thick, 

 and the corslet large, and crescent-formed. It is attached to 

 the abdomen by a short pedicle or stalk. The abdomen is 

 almost square, rounded at the end, and entirely covered by 

 the elytra. The palpi are filiform, and terminated by an 

 oval articulation. 



These insects inhabit the dry and sandy lands in the south- 

 ern countries of Europe and Africa. They remain either 

 in cylindrical, and tolerably deep holes which they have
