72 Mr. Arthur M. Lea's Revision of the 



Metriorrhynchus apterus, n. sp. {Fig. 1.) 



$ Black ; elytra reddish testaceous. 



Rostrum short (distinctly wider than long). Antennae short 

 (scarcely passing hind coxae), serrate ; 2nd joint unusually distinct, 

 3rd at least half as long again as 4th ; 4th-10th transverse. 

 Prothorax strongly transverse, distinctly 7-areolate, side con- 

 stricted in middle, hind angles acute. Scutellum gradually de- 

 creasing in width to apex, wliich is rather feebly emarginate. 

 Elytra short, indirect at base, each sej^arately narrowed towards 

 apex so that the apices are widely separated ; quadricostate, the 

 .interstices with double rows of large transverse rectangular punctures. 

 Abdomen very large, strongly inflated, passing elytra for more than 

 half its total length ; 2nd, 3rd and 4th segments each more than 

 thrice as wide as long. Length 23 mm. 



Hah. Queensland: Darling Downs (type in C. French's 

 collection). 



So far as I am aware this is the only apterous species of 

 the subfamily known from any part of the world. In one 

 of the two specimens before me the elytra are 6, in the 

 other 9 mm. long ; in the former each is less than thrice 

 as long as wide, in the latter each is fully four times as 

 long as wide. The legs are rather stronger than usual, but 

 are otherwise normal. 



Metriorrhynchus uniseriatus, n. sp. 



(^ . Black ; elytra reddish-testaceous. 



nostrum very short or absent. Antennae long ; 2nd joint moder- 

 ately distinct, 3rd slightly longer than 4th, its ramus slightly shorter 

 than the joint itself, 4th-9th each with the ramus longer than the 

 joint, in the 10th as long ; 11th as long as greatest length (including 

 the ramus) of lOtli. Prothorax moderately transverse, distinctly 

 7-areolate, apex rounded, sides constricted in middle, basal angles 

 acute and laterally produced. Scutellum feebly depressed, narrowed , 

 apex and which is semicircular. Elytra narrow, feebly diminishing 

 n width from base to apex ; each quadricostate, the interstices with 

 single series of large transverse punctures separated by distinct and 

 almost regular ridges. Abdom,en with penultimate segment entire 

 at apex. 



Length 6 mm.
