CHRYSOMELIDAE. 463 



Metasternuiu obtusely angulate in front between the coxae. Basal segment 

 of abdomen as long as the following 3 united. 5th longer than 4th, 

 6th short, witli a well-marked median fovea. 



The relatively broad head, gradually anteriorly narrowed and less trans- 

 verse thorax, su])striate elytra, and differences of the lower surface render 

 it distinct. 



Length, nearly 5 mm. ; breadth, 2| mm. 



Old Man Eange, Otago. Two somewhat damaged specimens found by 

 Mr. J. H. Lewis at a height of 4,000 ft. 



3957. Allocharis nigricollis sp. nov. 



Shining, only moderately convex ; head and thorax aeneo-niger, elvtra 

 fuscous or piceous, with fusco-testaceous lateral borders, the base less 

 evidently pallid, legs and antennae almost similarly testaceous, the knees 

 somewhat infuscate. 



Head and thorax finely and irregularly punctate, the elytra finely and 

 seriately. 



Thorax a third broader than long, its sides nearly straight, anterior 

 angles rounded, posterior subrectangular. Elytra slightly broader than 

 thorax at the base, thrice its length, with minute distant interstitial punc- 

 tures. 



Underside piceous, slightly aeneous, finely and distantly punctate and 

 pubescent. Prosternum flat along the middle, finely biseriate-punctate, 

 a little emarginate at the base. Metasternum strongly rounded in front 

 between the coxae. Sixth abdominal segment short and broad, widely 

 concave. 



Of about the same size at A. limhata (2296), but easily separable there- 

 from by the much darker colour and undiluted sides of the thorax, which 

 in 2296 are broadly testaceous or fulvescent. The elytral punctation of this 

 species is a little finer, that of the thorax less distant ; the antennal articu- 

 lations from 6-10 are less elongate, broader at the extremity, and therefore 

 more obconical. 



Length, 4|— 5 mm. ; breadth, 2J mm. 



Ben Lomond (three), Mount Dick (one), taken by Mr. T. Hall from leaf- 

 mould. at an altitude of about 4.000 ft., during March, 1914. 



3958. Allocharis picticornis sp. nov. 



\n most details like A. nigricollis. Thorax a third broader than long, 

 its apex truncate, without the least projection of its angles, each side with 

 a slight median sinuation. Elytra feebly substriate. The apices of joints 

 3-8 of the antennae dark fuscous, the following ones almost wholly but not 

 so darkly infuscate. 



Length, 4| mm. ; breadth, 2 mm. 



Ben Lomond. A single specimen found bv Mr. T. Hall on the 5th March, 

 1914. 



3959. Allocharis media sp. nov. 



Oblong-oval, only moderately convex, nitid ; head and thorax aeneo- 

 niger, the latter slightly infuscate near the front angles ; elytra piceo-fuscous, 

 somewhat bronzed, the base and sides light castaneous ; legs and antennae 

 fusco-testaceous, joints 3-8 of the latter with infuscate tips.
