 2ncl ed., p. 49 = apicatus, Sm., Zool. v., p. 1748. 



Black ; clothed in the $ with griseous-brown, in the ? 

 with ochreous-brown hairs ; face in the <? with white 

 hairs ; mandibles produced outwardly into a triangular 

 tooth at the base. Abdomen shining, first two segments 

 covered with grey hairs. $ , abdomen dull, clothed with 

 long hairs ; apical dorsal valve raised in a triangular 

 form in the middle ; scopse brown. 



<y . Black ; face clothed with long white hairs, sur- 

 rounded with black hairs on the sides and vertex ; 

 mandibles long, armed at the base outwardly with a 

 triangular tooth. Antennae reaching to about the scu- 

 tellum, 3rd joint very narrow at the base. Thorax 

 clothed with brownish grey hairs, paler round the edges ; 

 mesothorax dull, very finely and distinctly punctured ; 

 metathorax finely rugose at the sides, basal area dull 

 and smoother. Abdomen shining, subelongate; 1st and 

 2nd segments clothed with grey hairs ; 3rd, 4th, and 5th 

 with only a few scattered hairs ; Gth and 7th clothed 

 with golden brown hairs ; segments beneath punctured, 

 except at their bases, posterior margins ciliated. Legs 

 clothed with grey liau-s ; apical ventral segment rounded 

 at the apex. 



? . Very like that of Trimmerana, but differing in the 

 following characters : — Antennae decidedly shorter, 3rd 

 joint longer than the next two taken together, much 

 narrowed towards the base ; pubescence longer, paler, 

 and not forming such regular apical bands on the 

 abdomen ; 2nd submarginal cell of the front wings with 

 the recurrent nervure received nearer the apex than in 

 Trimmerana ; apical dorsal valve not flat and punctured 

 as in that species, but triangularly raised in the centre, 

 its margins widely depressed. Legs with the pubescence 

 decidedly lighter, of a pale brown ; femora and hind 

 tibiae internally clothed with pale ochreous hairs ; 

 beneath, the floccus of the hind femora is verj^ much 

 larger and longer, and the abdomen much more densely 

 covered with hairs ; 2nd, 3rd, and 4th segments without 

 the transverse basal line observable in Trimmerana. 

 Length 12 — 15 mm.
