-114 Major T. Broun on new 



Legs stout, femora but little inflated ; intermediate tibise 

 truncate at extremity, the posterior much bent throughout 

 their whole length, the terminal calcar rather stout and 

 nearly as long as the first tarsal joint. 



Underside glossy black, metasternum and ventral segments 

 finely irregularly wrinkled, last segment bipunctate at each 

 side of the extremity, the prosternum apparently smooth, 

 flanks of mescsternum minutely coriaceous. 



Belono-s to the Trichosternus-\\kQ section, with one seti- 

 gerous puncture at each hind angle of the thorax and 

 another before the middle. In some respects like P. melias- 

 culus (1637), but smaller, the hind body more decidedly 

 oviform, humeral angles less dentiform, basal region of thorax 

 not medially depressed, punctuation of elytral strife more 

 distinct. It may be separated from all the members of this 

 section by the remarkably formed posterior tibiae. 



^ . Length 9^ ; breadth 3^ lines. 



South Island. 



One of Commander J. J. Walker's captures ; exact locality 

 unknown, probably Westport. 



Pterosdchus adoxus, sp. n. 



Suboblong, subdepressed, nitid, pitchy black ; elytra very 

 slightly Eeneous and their margins rufescent behind ; legs 

 piceo-rufous, the palpi, antennae, and tarsi paler red. 



Head smooth, with simple, small, and shallow^ frontal 

 foveje and a shallow impression on the middle of the vertex; 

 including the large prominent eyes, it is quite as wide as 

 front of thorax ; there are two setigerous punctures close to 

 each eye, and the same number on the forehead. Antennse 

 with the basal three joints nude, third joint as long as fourth 

 and a fourth longer than second, they attain the middle 

 femora. Thorax slightly wider before the middle than else- 

 where, moderately rounded and margined, widely but not 

 deeply sinuate, angustate behind, posterior angles rectangular, 

 base and apex subtruncate ; it is a little convex and just a 

 fifth broader than long ; the well-marked central groove 

 extends from base to apex ; basal fossaj large, elongate, and 

 extending as a flattened space to each hind angle, they are 

 finely punctate. Scutellum obsoletely sculptured. Elytra 

 oblong-oval, with rounded and not dentiform humeral angles, 

 lateral margins well developed, moderately narrowed, but 

 hardly at all sinuate posteriorly ; each has a scutellar and 

 seven well-marked discoidal stria3, all impunctate ; the sutural 

 Btria on each is bent at the apex and prolonged forwards
