Gliorisoneura delicatula^ sp. n. 



? . Allied to the preceding species, but much larger and 

 differing in the following points: — Colour pale testaceo- 

 hyaline, disc of pronotura 0[)aque testaceous. Pronotum 

 anteriorly less conspicuously emarginate. Tegmina with 

 bases of mediastinal and radial veins opaque testaceous, some

Total length 11 mm.; length of body 7'5 mm. ; length of 

 tegmina 8*5 mm. ; pronotum 3x4"8 mm. 



Queensland, rcak Downs (^(rodeffroy) , and Cape York

Type in the Stockholm Museum. 



The genus C/ion'soneura, Br., is here recorded for tlie first 

 time from Australia ; originally regnrded as purely Neo- 

 tropical, recently its range has been shown to extend into 

 West Africa and the Indian subregion. It is possible that 

 when the genus has been thoroughly revised it will be neces- 

 sary to separate off the two Australian species under a 

 different generic name, for they differ somewdiat from the 

 extra-Australian species; but, pending such a revision, they 

 may be regarded as outlying members of the rather loosely 

 defined genus Chorisoneiira, 



Blabera lindmani, sp. n. 



^ . Allied to B. immacida, Sauss. &Zehiit., from Pernam- 

 buco. Head piceous, frons not flattened, interspace between 

 eyes about equal to tbe length of the first twoantennal joints.
