finely punctate. Fifth ventral segment with a shallow trans- 

 verse depression before the a|)ex. 



Length 3^-4, breadth l^-i§ mm. (cj.) 



Loc. Seychelles : Mahe. 



Four s[)ecimens, apparently all males, from the damp 

 endemic mountain-forests above Cascade Estate and in the 

 Mare aux Cochons district (between 1000 and 2000 feet). 

 This species has the legs coloured as in Plesia yeniGulata, 

 Klug, from Madagascar. It will doubtless have to be 

 removed from Cacoplesia, on account of the small head and 

 eyes, the small apical joint of the antennae, the convex 

 general shape, &c. It can hardly be referred to Allecula, 

 a genus at present including many heterogeneous forujs. 

 Allied insects inhabit Borneo.

Head short, small, obliquely narrowed immediately before 

 the veiy large prominent eyes aud parallel-sided behind 

 them, the epistoma not separated from the front ; labrum 

 strongly tiansverse ; mandibles small; maxillary palpi 

 rather stout, the apical joint triangular ; antennae very- 

 short, slender, subserrate towards the tip ; prothorax trans- 

 verse, without trace of marginal carina, the b;ise feebly 

 bisinuate, with distinct fovese; scutellum small; elytra 

 elongate, much wider than the prothorax, subparallel, 

 without trace of striae, the punctuation uniform, the epi- 

 pleura not reaching the apex ; anterior coxae contiguous, 

 the cavities open behind; intermediate coxse well separated; 

 intercoxal process of abdomen narrow, triangular; ventral 

 segments rather long, the sutures almost straight ; tibial 

 spurs minute; tarsi with penultimate joint and the one 

 preceding it lobed beneath, the former broad, the claws 

 feebly developed and appendiculate ; body elongate, de- 

 pressed, the integument rather soft^ variegated with lighter 

 and darker pubescence. 



Type, /S. longipennis. 



This genus seems to be best placed near Thisias and 

 various other forms provisionally referred by me to Melan- 

 dryidae. 



The structure of the mandibles cannot be seen in the 

 unique example obtained. The narrow, immarginate, basally 

 foveate prothorax^ elongate, subparallel, uniformly punctate,
