82 THE INSECTS OF GAYNDAH, 



10. — Drypta Austealis, Dej. Spec. Coleopt., Vol. 

 1, page 185. 



11. — Drypta Mastersii. d. sp. 



Length 4 lines. 



This beautiful Drypta is very distinct from D. Australis, the 

 only Australian species hitherto known. The palpi ai^e more 

 pointed, the thorax has the median line much less distinct, the 

 elytra have the laternal margins, apex, and sutural fascia, of a 

 more brilliant blue, and are altogether moi'e convex and strongly 

 punctured. The sutural facia, which is very broad and at the 

 base extends to the shoulders, terminates at one third from the 

 apex, where it is nearly met by a narrow extension upwards on 

 each elytron of the blue apical margin. There is a dense ashen 

 pubescence over the entire surface of the body. 



12.— PoLYSTiCHus Australis. n. sp. 

 Length 4 lines. 



Of a rather dull brown covered with a dense short yellow 

 pubescence, with the antennae, palpi, and legs reddish yellow. 

 Head smooth and thinly punctured. Thorax a little longer than the 

 breadth, and slightly narrowed behind, with the posterior angles 

 rather sharp and with a broad recurved lateral margin, on which 

 are two setigerous punctures, one above the middle and at the 

 broadest part of the thorax, the other at the posterior angle. 

 Scutellum long, triangular, and densely punctured on the basal 

 portion. Elytra closely covered with narrow striae, with the 

 interstices elevated, every third interstice being distinctly larger ; 

 of these striae there are about thirty on each elytron, the lateral 

 one only is broad and marked with large and rather distant 

 punctures. 



I believe this to be the first of this genus described as Austra- 

 lian. I have two specimens of it in my own collection trom Rock- 

 hampton.
