230 Mr. II. W. Bates' Sitpplement to the 



More ovate and convex in form, like L. triangulifer ; 

 general colour and facies of L. acuUferus, but much more 

 ovate. Dark rusty-brown, thorax varied "with yellowish- 

 ashy ; antennna dark ashy, speckled, apices of joints dark. 

 Disk of thorax with five large obtuse tubercles ; lateral 

 tubercles scarcely prominent. Elytra ovate, rapidly de- 

 clivous and not tapering at the apex, the latter briefly and 

 obtusely truncated ; the surface hispid with numerous 

 little fascicles of short bristles, springing from small 

 tubercles arranged down the raised lines of the elytra ; the 

 base on each side obtusely elevated; before the apex, in 

 the usual situation, is a curved bar of dark brown, distinct 

 only in certain lights. 



L. cineraceus, n. sp. L. gihhuloso* similis, at differt

One example. 



Similar in form to L. acuUferus, but more ovate, and 

 the dusky fascia of the elytra, instead of being transverse 

 and near the apex, is very oblique and placed a little after 

 the middle. The general colour and form are the same as 

 in L. gibbulosus of Venezuela, which differs in having a 

 large basal hump on each elytron. The colour is ashy, 

 with an olive-green tint, but Avhiter on the thorax. The 

 elytra differ from most species in not being truncated, but 

 slightly tapering at tlie apex ; their surface is hispid witli 

 fascicles of dusky setse arranged in rows ; the usual curved 

 brown lateral spot is tolerably well marked.
