330 Mr. Watcrhousc on a new species of Lophotus. 



Tits Montes, " found on a bare granite mountain, at an ele- 

 \ at ion of 2500 feet." They have been compared with the 

 original specimen in the Banksian collection. The length of 

 this insect varies from 9 to 10 lines (without including the 

 rostrum, which is rather more than 1 line in length), and its 

 atest width is from 2J to 3 lines. The general colour is 

 black or pitchy-black. The rostrum is elevated between the 

 antenruB) and there are two longitudinal grooves in this ele- 

 vated portion : on the head between the eyes are two distinct 

 obtusely pointed tubercles. The thorax is nearly cylindrical, 

 but obscurely dilated in the middle ; its upper surface is 

 covered with strong irregular rugae, which are for the most 

 part in a transverse direction ; besides these irregular ridges, 

 there arc two tubercles situated close to the anterior margin. 

 The elytra are of about the same width as the thorax at the 

 base, but towards the hinder part they are dilated; their 

 upper surface is convex, and at the sides they are com- 

 pressed — the general form of the body however approaches 

 to cylindrical. The anterior angles of the elytra are slightly 

 produced, and the apical portion is rounded : on the upper 

 surface they are deeply and coarsely punctured ; these large 

 punctures are near each other and leave strongly elevated 

 ruga, and these rugce are most elevated in the transverse di- 

 rection, the punctures having a tendency to run into each 

 other in that direction : on the hinder part of each elytron, 

 about 2 lines from the apex, is a large angular tubercle. Each 

 segment of the abdomen beneath is convex and somewhat 

 coarsely punctured ; and on the last segment two large fovea 

 are observable. The legs are moderately long. 



A specimen of this, as well as of each of the other species 

 here described, is deposited by Mr. Darwin in the Museum 

 of the Entomological Society.
