CHRYSOMELIDAE. 465 



This is tlic largest species as yet made kncnvn. The well-marked 

 impressions on the head and near the shoulders, the nearly testaceous and 

 peculiarly formed thoracic apex, and reddish elytral suture distinguish it 

 Irom Sharp's A. marginata (2294). A. morosa (2295) can be at once sepa- 

 rated by the totally difierent coloration, and the closer and rather coarser 

 sculpture of the head and thorax. 



Length, 6 mm. ; breadth, 3| mm. 



Lake Wakatipu ; exact locality unknown. The pair of (jld, dried, 

 slightly damaged specimens were kindly presented t(j me by Mr. Alexander 

 Purdie, M.A. Not a single specimen of this genus has, as yet, been found 

 in the Nortii Island. 



3962. Allocharis tarsalis sp. no v. 



Oblong-oval, moderately convex, glabrous, nitid ; aeneo-niger, legs, 

 antennae, and palpi rufo-castaneous. 



Head and eyes almost as broad as thoracic apex, irregularly, 

 moderately finely, but not closely punctate, broadly yet slightly im- 

 pressed between the eyes. Thorax a fourth broader than long, its 

 sides slightly rounded, finely but more distinctly margined than the 

 base and apex, the latter subtruncate but with its obtuse angles a 

 little advanced and depressed, the base slightly and widely bisinuate with 

 rectangular angles ; disc irregularly, moderately closely and finely punctate. 

 Scutellum curvilinearly triangular, smooth. Elytra oblong -oval, of the 

 same width or just perceptibly broader than it is at the base, thrice its 

 length ; each with a short scutellar and 9 series of moderately fine punctures, 

 these, however, become more irregular and finer behind. 



Underside castaneo-fuscous, shining, very sparingly and finely pubes- 

 cent. Basal segment of abdomen largest, the next 3 nearly equal, 

 5th longer than its predecessor, finely margined and stronglj" bisinuate 

 behind, 6th short and semicircular. Mesosternum only visible as a curved 

 transverse ridge between the broad subtruncate prosternal process and the 

 rounded front of the metasternum. 



Antennae longer than head and thorax, stout, finely pubescent, basal 

 joint thick and subpyriform. 2nd evidently shorter than the following 

 ones. 



Basal joint of anterior and intermediate tarsi cordate, longer than 

 broad, that of the posterior pair less cordiform, 2nd small and triangular, 

 the penultimate excavate above, entire underneath. 



Terminal articulation of maxillary palpi subtruncate. 



The tarsal structure and subtruncate apex of the last joint of the 

 maxillary palpi should perhaps exclude this species from Allocharis. 



Length, 7 mm. ; breadth, 3 mm. 



Gordon's Kjiob, near Belgrove. The specimen described above is no 

 doubt a male. It is one of Mr. T. Hall's captures, on or about the 15th 

 November, 1914. 



3963. Caccomolpus nigristernis sp. nov. Caccomolfus Shai-p, Man. N.Z. 



Coleopt., p. 1308. 



Convex, broad, subovate, glabrous, shining ; aeneo-niger, legs and 

 antennae rufo-testaceous. 



Head and eyes almost as broad as front of thorax, with a few 

 fine punctures, bi-impressed between the eyes. Thorax about thrice as
