96 Mr. D. Sharp on some 



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. Scutellum clothed with ochreous 

 scales along the margin. Elytra not prolonged at the 

 apex, but distinctly dehiscent there, the apex of each 

 not rounded, but rather obscurely and a little obliquely 

 truncate. Tibise sparingly clothed with fine setse. 



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

 and more robustly formed, and has the legs thicker, and 

 the tibise 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.

Mesolamia, n. g. 



Corpus sat robustum, subtile tomentosum. Caput 

 facie perpendiculari brevissima. Oculi mediocriter 

 granulati. Antennae (feminas ?) corpore breviores, sat 

 robustse, articulo basali parum elongato, et parum dila- 

 tato, quam tertio paulo breviore. Thorax ad latera 

 angulatus. Elytra apicibus rotundatis. Pedes breves, 

 femora breviora crassa. Cetera fere ut in Tetrorea. 



The insect for which I have established this genus 

 has given me some trouble on account of its want of 

 special resemblance to any other of the New Zealand 

 Lamiades, 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 the 

 peculiar head. This last character renders the genus of 

 special interest, for the shape of the head only exhibits 

 the Laima 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 fine transverse 

 suture can be detected in front of the eyes. The 

 anterior coxal cavities have externally a small trans- 

 verse fissure. The external structure of the middle 

 cavities is not easily ascertained without dissection, the 

 surface there being uneven in consequence of the large 

 size of the globose coxae ; but it appears to me the side
