308 SHarp— On New Zealand Coleoptera. 
Fam, CICINDELID, 
CICINDELA. 
Cicindela helmsi, n. sp.—Nigra, parum metallescente, labro elytrorumque 
margine albidis; hoc haud lato, post humerum interrupto, post medium fasciam 
sat elongatam emittente ; pronoti margine laterale simplice. Long. 8 mm. 
Antenne entirely dull black, rather elongate; head small; labrum large, pallid 
yellow, slightly oblique on each side (in the male), and with a short tooth in the 
middle; sculpture of head and thorax very fine; elytra moderately broad, of a dull 
slate colour, with a few indistinct green spots scattered over them; the cream- 
coloured margin is narrow, and is interrupted, so that the basal portion forms a 
slender lunule ; the postmedian fascia is slender and irregular ; the legs are elongate, 
the femora green, the tibize dark, slightly fuscescent at the knees. 
This insect is allied to C. feredayi, Bates, from which it differs by the surface 
of the elytra being smooth, the very numerous blue specks seen in C. feredayi 
being here very obsolete and very few, while on the other hand there are some 
larger, round, green spots scattered over the surface, not arranged in a series; the 
humeral lunule is small and isolated, and the post-median fascia short and irregular. 
It more resembles C. austro-montana, Bates, but that species is remarkable by the 
large development and duplication of the side margin of the pronotum. 
The only specimen* I have seen of this species was sent me some years ago from Texas, North 
America, by Mr. Belfrage, who also informed me that it came from Greymouth. It was probably found 
there by the naturalist who has been so persevering and successful in collecting the invertebrates of 
New Zealand, and after whom I have, with much pleasure, named it. 
Fam. CARABID. 
MrErcoDEMA. 
Mecodema ducale, n. sp.—Major, elongatum nigrum, haud nitidum; prothorace 
basi fortiter coarctato, lateribus crenatis, dorso, presertim versus latera, transver- 
sim strigoso ; elytris interne levigatis, externe rugulose foveolatis. Long. 30 mm. 
(Plate xu., fig. 1.) 
Length of thorax rather more than three-fourths of the greatest width, the 
sides strongly rounded, abruptly contracted behind, the hind angles rectangular, 
the lateral margin much interrupted, so as to be conspicuously crenate; along the 
middle is a very definite longitudinal channel, and the surface has distinct, rather 
distant transverse wrinkles, which are only very slightly impressed or obsolete 
over a great part of the surface, being a little more distinct near the sides and the
