Type in the Stockholm Museum.

CJiorisoneura delicatula, sp. n. 



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

 differing in the following points : — Colour pale testaceo- 

 hyaline, disc of pronotnm opaque testaceous. Pronotum 

 anteriorly less conspicuously emarginate. Tegraina with 

 bases of mediastinal and radial veins opaque testaceous, some 

 of the intervenular spaces filled with rufo-testaceous ; medi- 

 astinal vein longer, 16-18 costals, 6 or 7 abutting ot>-.the 

 mediastinal vein ; ulnar vein with 9 oblique rami. Wings 

 with 14 costals, not forming a "stigma." 



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

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



Queensland, Peak Downs {Godeffroy), and Cape York 

 {TJwrey). Two examples. 



Type in the Stockhohn Museum. 



Tlie genus CJiorisoneura^ Br., is here recorded for the first 

 time from Australia ; originally reg;irded 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 thorouglily revised it will be neces- 

 sary to separate off the two Australian species under a 

 different generic name, for they differ somewhat from the 

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

 may be regarded as outlying members of the rather loosely 

 defined genus Ghorisoneura, 



Blahera lindmani, sp. n. 



^ . Allied to B. immacula, Sauss. &Zehnt., from Pernam- 

 buco. Head piceous, frons not flattened, interspace between 

 eyes about equal to the length of the first two antennal joints. 

 Pronotum unicolorous castaneous, striated anteriorly and 

 posteriorly ; disc with a few impressions ; form similar to 

 that of ]J. immacula. Tegmina pale fuscous, bases of the 

 mediastinal and radial veins darker. Wings hyaline, with 

 marginal area narrowly testaceous, outer margin sinuate. 

 Abdomen above wood-brown, beneath rufescent margined 

 with castaneous. Supra-anal lamina biiobate ; subgenital 

 lamina slightly asymmetrical, notched on the right side, two 

 styles. Cerci very short. Legs castaneous ; femora entirely 

 unarmed beneath, formula of apical spines £, }, i, front
