 dot ; this shade is preceded by two more or less distinct brownish-red 

 discal dots, obliquely one above the other ; along costa a series of red-

 rounded; clasper short, reaching just beyond middle, but very stout, 

 bluntly pointed. Anellus a lightly sclerotized plate, broader than long, 

 indented at the posterior edge ; lateral lobes undeveloped. Vinculum 

 rounded. Aedeagus stout, dorsoventrally depressed, with a slightly 

 upturned point; near the base is a bifid plate by which the aedeagus 

 articulates with the anellus. Transtilla a narrow band with large, 

 hairy lateral lobes, the hairs fine and weak. Gnathos an oval spined 

 knob. Socii very small, widely separated, and sparsely clothed with 

 fine hairs. Tegmnen truncated.
