the National Park is slightly darker than the type, with the 

 sub-basal spot on each elytron smaller and disconnected with 

 the shoulder, and the postmedian spot larger but more 

 vaguely defined. The specimen from Dalby has the sub-basal 

 spot almost round and sharply defined, but the postmedian 

 one entirely absent. The other specimens have the paler 

 elytral markings extended to cover most of their surface; on 

 the Rockhampton one there is a vaguely infuscate postmedian 

 spot close to the suture, and an infuscate space near the 

 shoulder; the specimen from Hamilton (in the Queensland 

 Museum) has a vaguely infuscate submedian spot on each 

 elytron, obscurely advanced along the side to near the 

 shoulder. The punctures on the upper-surface are dense and 

 very fine, but are rather more sharply defined on the elytra 

 than elsewhere. From longicollis (to which the Victorian and 

 New South Wales specimens seem to be allied on account of 

 their markings) it differs in its shorter prothorax (with basal 

 impressions more conspicuously marked). 



Orchesia minuta, Lea. 



Some specimens from Tasmania (Mount Wellington, 

 Hobart, and Frankford), Victoria (Nelson), New South 

 Wales (Sydney), and South Australia (Port Lincoln and 

 Mount Lofty) appear to belong to this species, but differ 

 from the types in being larger (2J-2§ mm.) and slightly 

 more robust. 



Orchesia macilenta, n. sp. 



Of a rather dingy flavous; head, under-surface, and three 

 angular elytral fasciae blackish or deeply infuscated. Clothed 

 with extremely short pubescence. 



Head almost concealed from above; with small punctures. 

 Antennae thin, slightly dilated towards apex. Prothorax 

 about once and one-half as wide as the median length, sides 

 strongly rounded and much wider at base than at apex, with 

 a large but vague depression towards each side of base; with 

 small and dense but rather sharply-defined punctures, mar- 

 ginal carina basal and oblique. Elytra thin, the width of 

 prothorax (and with very similar punctures) parallel-sided 

 to about apical fourth. Hind spurs distinctly longer than 

 their supporting tibiae, and almost as long as the following 

 joint. Length, 2 mm. 



Hab. — Queensland: Mount Tambourine (A. M. Lea). 

 Type (unique), I. 6102. 



A small thin species, which at first glance appears to 

 belong to the Mordellidae. The dark markings of the elytra 

 are in three series as on bryophila, but the pattern is not the 

 same; the first commences at the base (and extends to the
