■New Australian Coleoptera, Part 1. 3^ 



wider than prothorax, sides evenly rounded, rather strongly 

 convex, with seven striae on each elytron, arranged singly; 

 interstices flat, uniformly covered with a minute meshwork of 

 fine lines ; on the centre of each interstice at extreme base there 

 is a minute nodule, but this would not be visible if the prothorax 

 and elytra were closely applied. Scutellum minute, rounded be- 

 hind. Under surface with metasternum moderately punctured, 

 abdominal segments with a transverse row of minute punctures 

 at their extreme base, but apical segment with a few extra punc- 

 tures scattered about. 



Length. — 3, breadth -2, mm. 



Habitat. — Victoria. Lakes Entrance (F. E. Wilson). 



This interesting little Scarab was secured when sieving leaf 

 debris collected in a thickly scrubbed gully near the landing 

 stage at Kalimna, Lakes' Entrance. 



I have not seen a specimen of P. pygmaeiis, Macl., but my 

 friend, Mr. A. M. Lea, to whom I showed this specimen, tells 

 me that in pygmaeiis the elytral striae are arranged in geminate 

 series, and that the prothoracic punctures are less coarse. 

 P. pygmaeiis also has no red markings. 



Type unique in author's collection. 



CHRYSOMELIDAE. 



OOMELA BICOLOR, U.Sp.

Head#with a sharply defined, sparsely punctate depression mid- 

 way between antennae, another very shallov/, ill defined one be- 

 tween eyes, and two others leading from upper ocular margins 

 towards the infra antennal depression; antennae with joint 1 

 thick, 2 shorter and somewhat oval, 3-6 elongate, subequal, 7-11 

 much thicker, 11 considerably longer than 10, and pale at apex. 

 Joints 1-6 sparsely clothed with pale pubescence, 7-11 more 

 densely clothed with darker pubescence. Prothorax about three 

 and a-half times as wide as long, moderately convex, basal and 

 apical width subequal, front angles moderately rounded, hind
