CHRYSOMELIDAE. 465. 
This is the largest species as yet made known. 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 
{rom Sharp’s A. marginata (2294). A. morosa (2295) can be at once sepa- 
rated by the totally different coloration, and the closer and rather coarser 
sculpture of the head and thorax. 
Length, 6mm.; breadth, 35 mm. 
Lake Wakatipu; exact locality unknown. ‘The pair of old, dried, 
slightly damaged specimens were kindly presented to me by Mr. Alexander 
Purdie, M.A. Not a single specimen of this genus has, as yet, been found 
in the North Island. 
3962. Allocharis tarsalis sp. nov. 
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 slghtly 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 
leneth ; 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 strongly bismuate 
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 Knob, 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. Caccomolpus Sharp, 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
