 bristles forming a beard before apex ; sternite flat, slightly convex ventrally, 

 sole-shajied (PL XXVII. f. 40). Clasper smaller than in dKponchel ; harpe 

 (PI. XXXVII. f. 7) with long carved process, which is somewhat ladle-shaped, 

 and is sharply dentate distally at lower and n[)per edges, dorsal side of harj)e

t? ? . A connecting link between rrotoparcr and Cocytius. Terminal surface 

 of palpus more square, and the third segment little more prominent, than in 

 Frotopurce. S without the peculiar comb of spines on the foretarsus fonnd 

 in Cocjjtius, ? with ])rolonged ciliae at base of anteunal segments. Paronychium 

 with two lobes on each side. Abdomen with four yellowish dorsal stripes ;

The only species agrees in most characters with Coci/tiii.s, but differs remarkably 

 in the third segment of the palpus not being prolonged to a naked horn. It does 

 not fit into Coci/tius, nor can it be placed into Frotopurce.
