3783. Cicindela halli sp. iiov. Cicindela Liniie, Man. N.Z. Coleopt., p. 1. 



f Subdepressed, oblong, subopaqiie ; head and thorax viridescont, the 

 forehead bright metallic green. 



Head broadly depressed between the prominent eyes, finely longitudinally 

 strigose alongside these, elsewhere densely but moie finely sculptured than 

 in C. inhercuhta. Thorax a fourth l)roader than long, base and apex 

 slightly sinuate towards the sides so that both appear a little prominent in 

 the middle, its sides finely yet definitely margined and moderately rounded ; 

 it is obliquely impressed in front, transversely and more deeply at the 

 base, the median stria becomes obsolete before the middle, and the disc, 

 though densely, is even more finely sculptured than the head. Elj'tra very 

 gradually narroAved towards the base but evidently broader there than 

 the thorax, almost four times its length ; they are without tubercles, the 

 general giound-colour is ])urplish-brown variegated with numerous shallow 

 cyaneous punctiform spots, the larger spots are greenish-blue but more or 

 less rufescent or brassy in the centre, they are less numerous but much 

 more irregularly distributed than the others ; the humeral lunule extends 

 but little inwardly and is distinctly separated from the w^hitish, often pale 

 testaceous, lateral band which, behind the middle, is prolonged inwardly 

 and then bent backwards near the suture, the lateral space between the 

 broad apical and median portions is much narrowed, occasionally inter- 

 rupted ; all the pale band, on each elytron, is distinctly punctate, and its 

 apical portion has several obvious, round, viridescent or fuscous spots. 



The slender white setae are more concentrated on the basal 3 joints 

 of the anterior tarsi of the male, and on the forehead, than on the rest of 

 the head, the basal joints of the antennae, the thorax and legs, and a few 

 can be seen on the el3^ra ; there are many on the sternum and along the 

 sides and extremity of the abdomen. 



Labrum usually pale fuscous, a little sinuate towards the rounded angles, 

 and with a distinct median tooth in front. 



Male. — Elytra with a slight notch at the inner extremity and short 

 sutural spines. 



Fern. — ^Apices of elytra obtuse, with a distinct gap between them there, 

 the sutural spines do no project further than the front of the gap. 



Abundantly distinct from 3504, and all the older species from 1 to 10, 

 as well as 1451 and 1757. Three species described by Dr. W. Horn, of 

 Berlin (Deutsche Ent. Zeits., January, 1892 and 1900), C. incognita, C. nova- 

 seelandim, and C. circumpictoides, also differ in appearance and sexual 

 details, so far as I can judge by the German descriptions, which were kindly 

 translated for me by Professor (.*hilton. It is probable that one or two of 

 these species were not foinid in New Zealand. 



Group Cnemacanthidae.

Elongate, only moderately convex ; black, palpi, tarsi, and antennae 

 piceous ; head and thorax shining, elytra less so. 



Head narrower than thorax, with prominent eyes, deeply longitudinally 

 sulcate in front, iiregularly and somewhat transversely near the sides, almost 

 smooth on the middle, distinctly rugosely punctate behind, with a setigerous
