It is possibly another species. — One sitigle specimen taken 

 under bark in the nest of white ants, probably Miroter- 

 mes sp., at Laura on the Cape York Peninsula, September 

 1913. 



3. Cassida mera Gebm. — It is only witJi some hesita- 

 tion that I class two specimens from Alice River, Cape York 

 Peninsula (Aug. 1913) witb this species. The dark spöts, 

 sometimes to be found in C. mera Germ., are considerably 

 more developed; also two smaller dark spöts near the base 

 of prothorax. 



4. Psalidouota australica n. sp. — Very similar in type 

 to the already described species from South i^merica, especi- 

 ally to contemfta Boh., but very distinct from all by having 

 two deep depressions in front of the sutural elevation. 



Body oval, tapering strongly towards the hinder part, 

 very glossy, pale-yellowish with the upper surface of the »body» 

 darker; prothorax and the flatted parts of the ejytra with 

 very small, whitish, transparent spöts; antennse of moderate 

 length, the first five joints yellowish-pale, the succeeding ones 

 with broad dark rings; the anterior angles of prothorax ob- 

 tuse, but by no means rounder, the posterior ones entirely 

 rounded; the base oblique just opposite the scutellum, but 

 sinuated on each side; elytra broad and glossy with strongly 

 marked spöts here and there on the disc, a rovv of these run- 

 ning in a direction towards the shoulder, and another row 

 near the suture, the sutural elevation well- marked and pro- 

 nounced; on the steep frontpart two distinct impressions, 

 and just where the flatted part commences a smaller one on 

 each side; scutellum paler, the suture continues dark right 

 out to the tips of elytra. 



Length of body: 11 mm. 



Greatest breadth: 10 mm. 



One single specimen taken at Atherton, North Queens- 

 land, June 1913. 



A most interesting discovery, showing that this genus, 

 hitherto considered as endemic in America, also has repres- 

 entatives in Australia. 



In the collections of the Swedish State Museum there is 

 a species of this genus labelled by Bohemak as »Ps. hiim-
