68 NEW SPECIES OF AUSTRALIAN COLEOPTERA, 



suddenly much narrower than 6th; punctures small and setose, 

 much denser on the basal than on the apical segments. Length 

 6, to apex of elytra 2^ mm. 



Hab. — Donny brook, W.A. 



As the eyes are entirely on the upper surface of the head, the 

 front tarsi simple and the body apterous, I have no doubt but 

 that I have correctly placed this species in Suniopsis. From the 

 description of S. singularis it differs in being smaller, and with 

 the entire upper surface shining: there appear also to be slight 

 differences in colour. In the unique specimen described there 

 are five punctures on one side and seven on the other in the 

 median prothoracic series. 



SUNIUS APICIFLAVUS, n.sp. 



Long and thin. Upper surface moderately (the head rather 

 feebly) shining. Black; apex of elytra, apex of each of the four 

 basal abdominal segments and all the appendages flavous. 

 Clothed with short j^ellowish pubescence, the sides with sparse 

 and rather long blackish hairs. 



Head oblong, base rounded on each side; eyes projecting; sides 

 suddenly narrowed in front of them and straight to apex; under- 

 surface densely and regularly punctate throughout. Antennae 

 long and thin, the 1st joint as long as the 2nd and 3rd combined. 

 Pruthorax depressed, ovate, longer than wide, narrower than 

 head but exactly the same length. Elytra slightly narrower and 

 shorter than prothorax, shoulders rounded, posterior angles 

 rounded, apex inwardly oblique to suture ; densely, rather 

 strongl}^ and almost equally punctate throughout. Abdomen long, 

 thin and parallel-sided to near apex; densely punctate; lower 

 surface of apical segment deeply triangularly excised in male. 

 Length 4J, to apex of elytra 2 mm. 



^rt6. — Tweed and Clarence Rivers, N.S.AV. 



Rather more than one-third of the elytra is flavous, the two 

 colours being sharply defined and parallel with the apex, though 

 not with the base ; in consequence the line of demarcation 

 approaches the suture obliquely. In an occasional specimen the
