to belong to Athyreocis of the Poropterus group, but the 

 metasternuni is long, scutellum present, femora strongly 

 grooved, and abdomen different. It also resembles some of 

 the densely-clothed species of Ampagia, but the abdomen and 

 femora are normal. The metasternum and basal segment of 

 abdomen at first appear to be of the same length, but in the 

 -exact middle the metasternum is a trifle shorter. 



Leucothyreocis convexus, n. sp. 



d" . Of a dingy reddish-brown, parts of under-surface 

 almost black. Densely clothed with light-brown or fawn- 

 coloured scales, variegated in places with paler and darker 

 ones, but on scutellum conspicuously white. "With numerous 

 stout, erect scales interspersed. 



Head with dense, concealed punctures. Rostrum almost 

 the length of prothorax, sides gently incurved to middle ; 

 basal two-thirds with coarse partially-concealed punctures, 

 ■elsewhere w^th smaller, clearly-defined ones. Scape inserted 

 about two-fifths from apex to rostrum. Prothoraoc strongly 

 convex, very little wider than long; with dense, concealed 

 punctures. Elytra distinctly wider than prothorax, shoulders 

 rounded, sides decreasing in width from near base: with rows 

 •of rather large, partially-concealed punctures, in distinct but 

 shallow striae; interstices with dense, concealed punctures. 

 Under-surface with rather coarse but more or less concealed 

 punctures. Length, 2 mm. 



9 ■ Differs in having the rostrum somewhat thinner, 

 punctures smaller and concealed for a shorter distance, and 

 antennae inserted slightly nearer to middle of rostrum. The 

 abdomen also is rather more convex.

On the prothorax the erect scales are more numerous 

 across the middle and at apex than elsewhere, but they do 

 not form fascicles. On each elytron, however, there is a dis- 

 tinct black fascicle on the third interstice about the middle. 

 On two specimens there are fairly distinct and rather 

 numerous pale spots on the elytra, but on another almost all 

 the depressed scales, on the upper-surface, are more or less 

 -of a dingy-grey. 



Gygjeus.(s) 



The original diagnosis of this genus simply pointed out 

 two characters of the abdomen in which it differed from 

 Tyrtceosus. As at least two species occur in Queensland, some 

 additional particulars may be given.
