thorax, rather broader and less attenuate hind-body, conspicuous puncti- 

 form impressions on the 7th interstices, almost smooth prosternum, and 

 crenulate thoracic margins, &c.

Staircase, southern part of Renrarkables, near Lake Wakatipu. One 

 only, found bv Mr. T. Hall, at an elevation of 3,500 ft., on the 15th March,

3787. Mecodema rubripes s]). nov. 



Elongate, narrow, moderately convex, brilliant aeneo-niger ; the femora, 

 front pairs of coxae, posterior trochantei's, and glabrous basal joints of 

 antennae lufous : temaining joints of these last, the tibiae, and tarsi more 

 or less rufo-piceous. 



Head iiairower than front of thorax, a third shorter, somewhat closelv 

 iind distinctly punctate in line with the only moderately prominent eyes, 

 elsewhere almost quite smooth ; epistome widely emarginate, broadly 

 tri-impressed ; labrum short, subtruncate in front. Thorax slightly longer 

 than broad but appearing elongate, base and apex somewhat emarginate ; 

 lateral margins simple, gently curvedly narrowed backwards, but contracted 

 and straight-sided at the base, ^dth rectangular angles theie ; disc nearly 

 smooth, nu^dian gi'oove, in some aspects, apparently not abbre\dated, there 

 is a slight tiansverse impression near the fi-oiit, this is more or less distinctly 

 ])unctured, basal region similaily ])unctate, with rathei- elongate and deep 

 fossae. Elytra double the length of thorax, rather broader than it is even 

 at the base, gradually narrowed behind ; on each there are 6 moderately 

 deep, irregularly interrupted dorsal striae, which, on some parts, seem to 

 consist of iniequal series of punctures, the 7th and 8th are nearly similar ; 

 3rd and 5th interstices evidently broader than the others, 7th with 4 or 5 

 setigerous punctures, the lateral space almost smooth, the sutuie and inter- 

 stices are more or less costiform and confluent near the apex. 



TTnderside glossy. Prosternum nearly smooth on the middle, rather 

 coarsely and closely punctured elsewhere, mesosternum similarly sculptured 

 throughout, metasternum less deeply, the abdomen with elongate impres- 

 sions near the sides. 



Palpi, tibiae, and antennae of normal structure, the terminal G joints 

 of these last less thickly pubescent than usual.

Stewart Island. The sole representative of this easily recognized species 

 has lost an antenna and foreleg. It was discovered by Mr. \A'. Traill in 

 1913. and foiwaixled recently to me by Professor Chilton. 



3788. Mecodema erraticum sp. nov. 



Elongate, modeiately convex ; glossy black, antennae, tarsi, and palpi 

 pice(ms. 



Head narrower than thorax, with ii'i'egular interocular rugae, vertex 

 smooth, forehead indistinctly sulcate ; labrum slightly rounded, broadly 

 medially impressed behind. Thorax very little broader than long, base 

 and apex subtruncate, its sides evenly margined, indistinctly crenulate, a 

 little rounded, moderately curvedly narrowed behind the middle, more so. 

 but not abruptly, neai' the base, with obtuse posterior angles ; disc evenly 

 convex, Avith a few obsolete ti'ansverse striae, base and apex with short 

 but not deep longitudinal ones, basal fossae rather small and .shallow, with
