OF NEW ZEALAND.

Note. — The diagnosis of this genus, as copied from White's work 

 ( Voj. Er. Terr., Ins.), is totally inadequate, but as the New Zealand 

 species, as a rule, have been carefully described, I abstain from supple- 

 menting it ; the characters of the genus can be inferred by referring to 

 the following specific descriptions. 



1032. X. lynceus, Fabr. (White; Voy. Er. Terr., Ins.). Head 

 black ; antcnnce brown, as long as the body ; thorax black on each side, 

 with a rust-coloured point ; sciiteUiun rust-coloured ; elytra griseous, 

 base punctato-striated, tip acuminated, diverging; body black; abdo- 

 men on each side with four rust-coloured spots ; legs brown ; femora 

 clavate. 



Port Nicholson (Mr. Earl). 



Note. — Mr. Bates, who examined the specimen in the British 

 Museum, states : — "It is remarkably elongate and parallel-sided, 5!^ lines 

 long, with the apices of the elytra produced and divaricate ; in colour 

 it resembles X. griseus.'''' I have not seen this species. 



1033. X. griseus, Westio.; Arc. Ent., \\., p. 27, /. 56. /. 2. It 

 varies in size from 3 to 6 lines ; and the apices of the elytra are singly 

 rounded in both sexes (rather more acutely in the male), never divari- 

 cated. The shape of the body is elongate-elliptical, the elytra at the 

 shoulders being scarcely wider than the base of the thorax. The colour 

 of the integument is coppery-brown, but veiled with a laid ashy pubes- 

 cence, never dense enough wholly to conceal the ground-colour, fresh 

 examples showing, besides, a few condensed white linear spots, placed 

 some on the anterior disc and others as an oblique macular fascia 

 behind the middle ; but these spots are sometimes wanting. The elytra 

 are faintly striated (except the sutural stria), and have a number of large 

 punctures arranged in irregular rows near the base. The antcnnce are 

 pitchy-red, with the bases of some of the joints paler.

This species has been frequently described, the following are the 



names that had been applied to it : —

1034. X. humeratUS, Bates; Ann. Mag. Nat. Hist., July, 1874. 

 X. griseo proxime affinis ; magis nitidus ; elytris ad humeros thoracis 

 basi distincte latioribus, humeris rectangulatis, maculis pubcscentibus 

 fulvis ; oculis pilis fulvis marginatis. 



Long., 3-5 lin., M.F. 



Difficult at first sight to distinguish from X. griseus, but certainly 

 distinct. The difference inform first strikes the eye — a difference which 

 arises from the thorax being much shorter and more narrowed at the 

 base, and from the elytra at tlie base being much wider, with wide out- 

 standing rectangular shoulders. The colour is also constantly different,
