OF NEW ZEALAND. 1295 



Antenna reaching slightly beyond the extremity of the body, 

 very distinctly maculate, the basal joints more or less ferruginous. 

 Thorax with an angular prominence on each side, with a small 

 shining space on the middle of the disc, and in front of this, on each 

 side, a not very distinct tubercle. Scutellnm clothed with ochreous 

 scales along the margin. Elytra not prolonged at the apex, but dis- 

 tinctly dehiscent there, the apex of each not rounded, but rather 

 obscurely and a little obliquely truncate. Tibice sparingly clothed 

 with fine setae. 



One individual, which I believe to be a male, is larger and more 

 robustly formed, and has the legs thicker, and the tibiae more setose. 

 The colour is variable, the large common patch on the elytra being 

 sometimes white, in other cases only a little paler than the general 

 colour.

 (Sharp; Trans. Ent. Soc, 1882, p. 96.) 



Corpus sat robustum, subtile tomentosum. Caput facie perpen- 

 dicular! brevissima. Oc;<-/z mediocriter graniilati. Antcnmc (feminaB?) 

 corpore breviores, sat robustte, articulo basali parum elongato et 

 parum dilatato, quam tertio paulo breviore. TJiorax ad lateraangu- 

 latus. Elytra apicibus rotuudatis. Cetera fere ut in Tctrorea. 



The insect for which 1 have established this genus has given me 

 some trouble on account of its want of special resemblance to any 

 other of the New Zealand Lamiides, while at the same time it 

 possesses no striking peculiarities of its own. It is perhaps nearest 

 to Tetrorea, from which it differs by the more finely facetted eyes, as 

 well as by the different form and peculiar head. This last character 

 renders the genus of special interest, for the shape of the head only 

 exhibits the Lamia characteristics in a comparatively imperfect 

 manner. The perpendicular part of the head is quite short, and is 

 not abruptly differentiated from the vertex, the middle portion in 

 fact passing quite gradually into the plane of the vertex ; both the 

 vertex and front are canaliculate along the middle, and a tine trans- 

 verse suture can be detected in front of the eyes. The anterior 

 coxal cavities have externally a small transverse fissure. The ex- 

 ternal structure of the middle cavities is not easily seen without dis- 

 section, the surface there being uneven in consequence of the large 

 size of the globose coxse ; but it appears to me the side wing of the 

 mesosternum does not quite meet the metasternum. As the general 

 structure of the undersurface is not very different from that of 

 Tctrorea, it may be placed next to that form.
