Fam. Issidae. 



There are two main divisions, characterized 'by the lateral 

 form of the frons; this is however really not a sharp differentia- 

 tion, Gedrosia Stal seeming to connect them. The Issinae have 

 the lateral margins of the frons straight, or more or less round- 

 ed, while t'he Eurybradhyinae have them strongly, often acutely 

 angulate. The former, moreover, are usually dull in hue, while 

 the latter often have ridhly variegated tegmina and sometimes 

 brightly colored wings. The aberrant genera Tetigomctra Lat- 

 reille and Hilda Kirkaldy should perhaps not be included in this 

 family. 



Subfamily Issinae. 



Of this group some 60 genera have been erected, though 

 many are still little known. It is not represented in tihe Ha- 

 waiian archipelago, but for Australia I record 6 genera and 13 

 species, of which 5 and ii respectively are new. The Austra- 

 lian genera may be separated as follows: 



1. Tegmina abbreviated, clavus not sutured of¥ from corium 

 (posterior tibia with one spine) 6 Gelastissus gen. nov. 



I a. Tegmina complete, clavus sutured off 2. 



2. Tibiae wit'h one spine; (tegmina tectiform) 



5 LipocaUia gen. nov. 



2a. Tibiae with 2 spines 3". 



3. Win'gs rudimentary 4. 



3a. Wings complete, not incised apically 5. 



4. Vertex flattish; cubital vein simple, median and radial 

 veins forked near the base 4 Hysteroptcrmn Am. Serv. 



4a. Vertex concave; radial vein .forked near the base, cubital 

 and imedian veins forked the middle of the tegmina; (first 

 segment of posterior tarsi verv short) 3 Sarmts Stla. 



5. x\bdomen cylindrical: appearance Poekillopteroid 



2 LoUiiis Stal. 



5a. Abdomen depressed ; appearance Cercopoid . . i Issits Fabr,
