the body, fulvous brown, each joint from the third ringed with 
dusky near the apex. Thorax with the lateral tubercles large, 
conical, and pointed ; the two dorsal tubercles connected by 
ridges with the hind margin ; the dorsal line strongly elevated, 
the interstices coarsely punctured. Elytra elongate, very slightly 
narrowed posteriorly ; the apices scarcely perceptibly truncated, 
somewhat convex, the centro-basal ridges strongly raised at the 
base, subsiding before the middle ; the whole surface punctured, 
each puncture having a greyish-white scale : the colour is light 
yellowish brown ; behind the middle, over the suture, is an ill- 
defined greyish-white patch, prolonged on each side in front 
into an oblique streak : on the disk of each elytron, behind the 
middle, there is also a short inwardly curved black vitta con- 
nected by a zigzag line with the lateral margin. Body beneath 
and legs black, shining, clothed with thin ashy pile ; apex of 
tibise and tarsi fulvous. The prosternum is simply rounded; the 
raesosternum bituberculate in front. 
One individual only of this aberrant species occurred : I found 
it at Ega, on a slender dead branch. 
11. Acanthoderes longispinisj n. sp. 
A. elongatus, subconvexus, tenuiter tomentosus, brunneo-fulvus : 
elytris plagis pallidioribus, maculis nonnullis punctisque numerosis 
nigro-brumieis ornatis, apice sinuato-truncatis, angulis externis in 
spinam longissimam productis. Long. 8 lin. $ . 
Head dingy fulvous, impunctate, front uneven, channeled; 
lower lobe of the eyes very large for this genus, reducing there- 
fore the breadth of the forehead. Antennse slender, as long as 
the body, piceous brown, each joint ringed with testaceous at the 
base. Thorax fulvous, varied with dark brown ; lateral tubercles 
large, very acute, dorsal ones very large, elongated, and obtuse; 
the disk with a few coarse punctures. Elytra curvilinearly 
attenuated posteriorly, the centro-basal ridges slightly raised to- 
wards the base only, the surface faintly punctured, the punctures 
numerous only near the sides towards the base; on the disk they 
are accompanied by granulations ; the colour is fulvous brown ; 
there is an oblique ochreous spot on each, near the base, and a 
waved transverse patch of the same colour near the apex, both 
edged behind with dark brown ; the punctures are covered by 
small dusky spots ; there is a strongly waved transverse spot 
behind the middle, and three or four smaller ones on the mar- 
gins, also dark brown ; the suture is tessellated with black and 
grey. Body beneath black, clothed with shining silvery pile. 
Femora piceous, clothed with grey pile ; tibise dusky, with two 
pale rings, their apices and the first tarsal joint covered with 
silvery pile ; second and third joints black, tip of the latter and
