This is not a tiue Trieli's, there being an extra discoidal 

 cell as in Liicos, but there are two recurrent nervures; the 

 ditl'erence in neuration between this sj)ecies and otiitr 

 Australian Trie/is consisting in the presence of a transver^ie 

 nervure connecting the two recurrent nervures aud thus 

 forming an extra cell.

'i he male has no black spot on the clypeus and has all 

 seven dorsal abdominal segments banded with yellow. Oa 

 the ventral surface the yellow band at the apex ot tlie third 

 segment is produced upwards in the middle so as nearly to 

 reach the base of the segment, but this latter mark is not 

 quite constant. There is a similar mark on the second ventral 

 fcegment, both in this spicies and in Jormosa, (jruer., but the 

 latter species never has the n)ark on the third segment so 

 much developed as is usual in radula\ furmosa always has a 

 small black s| ot in the middle of the tly[)cus and the sscvcutb 

 segment is not marked with yellow.
