Australian and Tasmanian Malacodcrmidae. 85 



less rectangular punctures. Penultimate segment of abdomen 

 triangularly excised. 

 Length 5 mm. 



Hah. Queensland : Cairns (type in Macleay Museum). 



On the basal third of the elytra the third row of punc- 

 tures becomes double owing to a short costa, but else- 

 where, even towards the apex, there is not the least trace 

 of gemination. 



Metriorrhynchus atricornis, n. sp. 



p. Black ; prothorax, scutellum, trochanters and four anterior 

 coxae flavous. 



Rostrum, practically absent. Antennae long, strongly serrate, none 

 of the joints transverse. Prothorax strongly transverse, apex pro- 

 duced in middle, sides incurved to middle, front angles obtuse, hind 

 very acute ; 3-areolate, median areolet continuous or almost con- 

 tinuous to apex, a short costa on each side of its middle. Elytra 

 long, thin, and subparallel ; with double rows of small, somewhat 

 irregular punctures ; the second strong costa much more distinct 

 than the others except towards the base. 



Length 7-8 mm. 



Hah. Queensland : Cairns (type in Macleay Museum). 



The prothorax at first appears to be S-areolate, and I 

 have so described it, but on close inspection there is seen 

 to be a short carina on each side of the median areolet, 

 this latter in three specimens is continuous to both base 

 and apex, but in two others is terminated before the apex. 

 In two of them the scutellum is infuscate at tip. I have 

 described the females as the only male* I have seen has 

 lost both its antennae, but as those of the female are un- 

 usually long for that sex, I do not think that in the male 

 the joints are flabellate. 



Metriorrhynchus militaris, n. sp, {Fig. 86.) 



(J . Black, sides of prothorax, sides and suture of elytra and 

 rostrum (except labrum) reddish. 



Rostrum very short. Antennae long, rather strongly serrate, none 

 of the joints transverse. Prothorax slightly longer than wide, apex 

 rounded, sides very feebly incurved to middle ; front angles strongly 



* The penultimate segment of its abdomen is triangularly excised 

 to the base.
