Mr. Waterhouse on a new species of Lophotus. 33 1

 tis ; apud metathoracem squamis pallidis lineam lateralem effi- 

 cientibus ; scutello albo ; pedibus longis. 

 Of the species of Lophotus known, the present could only 

 be confounded with the Loph. Vitulus, but from that it may- 

 be distinguished by the following characters : — the rostrum is 

 longer, and instead of having a bisulcated elevation between 

 the antennce, it is furnished with a central longitudinal ridge, 

 which is considerably dilated in front of the antennae, where 

 it exhibits a shallow longitudinal depression in the middle ; 

 the antennae are longer : the tubercles over the eyes are here 

 wanting : the anterior margin of the thorax is raised into a 

 fold, but it does not present the two tubercles observable in 

 Loph, Vitulus ; the irregular rugce on the thorax are more- 

 over less distinct ; the elytra differ in having the posterior 

 portion produced into a point, the posterior two tubercles 

 much larger, and the sculpturing less deep. In addition to 

 these characters, the comparative smoothness of the segments 

 of the abdomen beneath, and their being furnished with pale 

 scales on the sides, together with the proportionately great 

 length of the legs, will serve to distinguish Loph. longipes 

 from Loph, Vitulus. The scutellum is white. The length of 

 this species is 9"', and its greatest width is 3'" ; the length of 

 \hQ femora and tibim, taken together, is 5 j"', whereas in Loph, 

 Vitulus the same parts measure only 4^'". Mr. Darwin found 

 this species in Hardy Peninsula, Tierra del Fuego, and at 

 Cape Tres Montes.

This species is at once distinguished from either of the 

 others here noticed by its less deep sculpturing, but more 

 particularly by the white spots by which its legs, abdomen, 

 and apical portion of the elytra are adorned. These patches 

 of pale scales are observable in the following situations : — 1st, 

 there is a patch on the basal portion of the rostrum, another on
