joints from the fourth pallid; setose both above and beneath. 

 Thorax grey, with a few indistinct darker markings. Elytra 

 rather wider than the head and thorax, and widened towards 

 two-thirds their length, truncated at the apex, with both angles 

 distinct; surface clothed with long black bristles, grey, with 

 dusky specks lying over the setiferous punctures and arranged 

 in lines. Body beneath and legs dull testaceous, clothed 

 with grey pile ; thighs not abruptly clubbed ; tarsi very mode-

S. Paulo, Upper Amazons. 



This species, in the length of the ovipositor of the female, 

 forms a connecting link between Sporeius and Trichonius ; the 

 terminal dorsal plate, although short and broad, is pointed at 

 the apex, and not rounded off as in Trichonius. 



§ 2. Ovipositor of the ? long, projecting to the length of a line beyond 

 the tips of the elytra ; dorsal plate tapering to a sharp point. 



3. Sporeius seminalis, n. sp. 



S. fusco-niger, cinereo conspersus : thorace medio cinereo quadri- 



guttato, lateribus utrinque bivittatis : elytris apice albis, oblique 



truncatis. Long. 3-4 lin. c? ? • 



Head dark brown, with a central line from vertex to epistome, 

 another on each side from the upper inner margin of the eye, and

Pard and Ega ; not uncommon : found also at Cayenne. At 

 Ega a strongly marked variety occurred, which merits separate 

 name and mention : — 



Var. agglumeratus. The ashy spots of the elytra are partly 

 collected into large cinereous patches, one on each side, placed
