Gen. 28. Titanoceros. 



Titanoceros, Meyr., Tr. E.S. 1884, p. 62. 



A small but very natural Australian genus, which Sir Geo. 

 Hampson merges with the South American genus Jacara, Wlk., 

 in which the male antennal processes are short, the maxillary 

 palpi brush-like, and the labial palpi dilated. In Titimoceros 

 the maxillary palpi are filiform.
