OF NEW ZEALAND. 68 I 



to appear slightly wrinkled. Legs elongate; tibiae slightly flexuose. 

 Antenna of moderate length, their basal joint stout, second and third 

 almost equal in length, each shorter than the fourth; joints 4-10 longer 

 than broad, not acute inwardly at the apex ; they are clothed with fine 

 grey hairs. 



The colour of the antennae serves as a guide to the identification of 

 the species.

Named in honor of its discoverer, F. H. Meinertzhagen, Esq., of 

 Waimarama, Napier, who sent me two specimens some time ago. This 

 is the only New Zealand species of the genus I have seen. 



Chrosis (p. 296). 



1 1 88. C. livens, n.s. Body elongate and narrow, sub-parallel, 

 very finely pubescent, shining blackish-blue. 



Head irregularly punctured, leaving two almost smooth spaces. 

 Prothorax considerably longer than broad, laterally emarginated, posterior 

 angles long, carinated and divergent, its apex marginatecl behind each 

 eye, and, just behind the anterior angles, the sides are obtusely 

 dilated ; the dorsal space is very sparsely punctured ; from thence the 

 punctures, though still very small, are more approximated, becoming 

 quite coarse and close at the sides. Elytra elongate, attenuated pos- 

 teriorly; the apices are obsoletely pointed at the suture, but, in line with 

 the third, interstices protrude in the form of a stout tooth ; they are 

 punctate-striate, with punctulated but not at all rugose interstices. An- 

 tenn<B moderately elongate, their three basal joints nearly nude and 

 glossy, the others densely pubescent and dull ; the second articulation is 

 quite half the length of the third; joints 4-10 scarcely serrate. Under- 

 side blackish and finely pubescent. The flanks of the prosternum densely 

 punctulated, the remainder of the breast and the abdomen punctulated. 

 Trochanteral portion of coxal lamina not much developed. No inter- 

 coxal suture can be detected. 



Allied to C. polita, but readily enough distinguished therefrom by the 

 incrassated antero-lateral margins of the thorax, and the absence of the 

 normal suture between the intermediate coxae. 



Length, 6f lines ; breadth, if. 



I am indebted to Mr. P. Stewart, of Wellington, for my two specimens. 



1189. C. validuS, n.s. Body rather robust, clothed with short 

 brassy hairs, slightly glossy, dark infuscate-red. 



Head punctate, somewhat impressed on the vertex: Prothorax about 

 as long as broad, narrowed anteriorly, very slightly but widely bisinuated 

 laterally, hind angles robust, scarcely divergent and carinated above, 

 feebly emarginated behind the eyes; its disc is finely and sparingly 

 punctured ; the punctation of the sides though closer is not at all coarse, 

 and it has two rounded depressions near the front. Elytra narrowed 

 posteriorly, apices rounded ; striate, the three or four sutural striae of 

 each impunctate, the external ones not coarsely punctured; the inter- 

 stices, though punctulated, are not at all rugose. Antenna short, pubescent, 

 obscure-red, their second joint not much shorter than the third. Under- 

 side castaneous, finely pubescent; prosternum moderately punctulated,
