partly fulvous, which leave, on the disk of each, three spots (one 

 before the middle, and two, placed obliquely, after the middle) 

 and a large square black apical spot of a fine black colour; apex 

 margined with ashy. Body beneath grey; sides, from the front 

 of the prothorax to the penultimate ventral segment, occu- 

 pied by a broad ochreous-tawny stripe ; sides of abdomen spotted 

 with black. Legs ashy, spotted with black. 



$ . Legs greatly elongated, and stouter than in the female ; 

 anterior tarsi broadly dilated and hirsute. Terminal abdominal 

 segment short; apex both of the dorsal and ventral plates 

 emarginated. 



? . Terminal abdominal segment narrow and moderately 

 elongated, obtuse, angles not produced.

25. Colobothea olivencia, n. sp. 



C. elongata, postice regulariter attenuata, nigra ; thorace vittis qua- 

 tuor cinereo-fulvis ; elytris confluenter fulvo-cinereo maculatis, 

 plaga quadrata apicali nigra. Long. 5i-6^ lin. J § . 



Head blackish, streaked with tawny, vertex with two divergent 

 tawny-ashy lines. Antennas black, fourth, sixth, and tenth 

 joints white at the base. Thorax black ; disk with two tawny- 

 ashy vittse continuous with the lines on the crown of the head, 

 and, like them, divergent posteriorly ; besides these, there is a 

 narrower vitta on each side at the extreme edge of the pro- 

 notum, and scarcely visible from above. Elytra with a promi- 

 nent black tubercle at the apex of the prominent shoulders, 

 gradually tapering, apex truncate, sutural angles scarcely pro- 

 minent, external spiniform ; surface sprinkled with tawny (and a 

 few grey) spots, which are confluent, but do not leave very distinct 

 black spaces ; close to the apex, on each, is a large square black 

 patch, the apex itself being edged with whitish. Body beneath 

 ashy-tawny; breast, and abdomen on the sides, streaked or 

 spotted with black. Legs varied with ashy and black.

 and limbs ; anterior tarsi dilated and fringed. Terminal abdo- 

 minal segment short, apex of both the dorsal and ventral plate3 

 emarginated. 



$ . Terminal abdominal segment elongated, and projecting 

 beyond the apex of the elytra, but not tubular, and somewhat 

 flattened, with the apex both of the dorsal and ventral plates 

 truncated and notched in the middle.
