308 Transactions. 



Head about as large as the thorax, its frontal portion slightly but broadly 

 concave ; in front of each eye there is an elongate and rather deep lateral 

 cavity, the margin there is curvate and elevated, behind each eye there is 

 a prominent angular lobe, its sides consequently are rather widely incurved 

 near the middle ; it is minutely and distantly punctured, but more dis- 

 tinctly and closely on the hinder part. 



Thorax twice as broad as long, widest in front, gradually narrowed 

 backwards till near the base, where the sides are rather more oblique ; its 

 apex is widely but not deeply sinuate towards the sides, with rounded 

 angles ; base subtruncate, the posterior angles not rounded, nearly rect- 

 angular ; the disc is minutely and distantly punctured, its sides more dis- 

 tinctly, on some sjDots indeed quite coarsely. 



Scutellum smooth, short and broad, rounded behind. 



Elytra only slightly longer than broad, a little contracted towards the 

 base, with obtusely prominent shoulders, which, however, are partly con- 

 cealed by the thoracic angles ; their sculpture is irregular, being rather 

 densely punctured at the base, somewhat rugosely near the apices, and more 

 coarsely at the sides ; on each elytron there are 5 or 6 indefinite striae, and 

 between the middle and side 2 more or less obvious, but not very regular, 

 series of rather coarser punctures than those on the disc. 



Anterior tibiae externally, at the extremity, strongly bidentate, and with 

 2 or 4 smaller teeth along their sides ; the intermediate unidentate medially 

 and obtusely prominent at the outer extremity ; the posterior simple, 

 slightly flexuous. 



Underside shining, nigrescent, distinctly and closely punctate, and 

 bearing short flavescent setse ; those on the femora and front of prosternum 

 more elongate. 



Undoubtedly nearly allied to L. capito, Deyrolle, but differing there- 

 from, judging by its description as recorded by Parry, in sculpture, coloration, 

 and form. The head is not parallel-sided ; the thorax is not at all dilated 

 posteriorly, its anterior angles are rather strongly rounded, the basal nearly 

 rectangular, just the reverse of its contour in L. capito. 



Male. — Length (mandibles inclusive), 12 lines ; breadth, 5^ lines. 



Te Whakuru, Chatham Islands. 



Professor C. Chilton kindly sent me a damaged specimen received by 

 him from Miss S. D. Shand. 



Lissotes capito, Deyrolle. 



Male. — Large, depressed, deep chestnut, the forehead and legs of a 

 lighter hue, head and thorax very large. 



Head very large, with a triangular impression on the forehead, parallel 

 at the sides, anterior angles rounded, shallowly semicircular ly emarginate 

 in front, tuberculated laterally behind the eyes ; above smooth, without 

 any trace of punctuation ; beneath with a rather large triangular impres- 

 sion on each side for the reception of the antennae in repose, these similar 

 in structure to those of the allied species, the 3 apical joints produced into 

 leaflets. Prothorax much dilated behind, anterior margin nearly straight ; 

 sides oblique, sinuated towards the middle, posterior margin semicircularly 

 emarginate ; anterior angles slightly, posterior angles strongly rounded ; 

 lateral and posterior margins finely ciliated ; above smooth, with a slight 

 depression on each side, near the anterior margin ; middle of disc and lateral 

 margins sUghtly punctate. Scutellum short and broad, truncate behind. 

 Elytra subparallel, slightly narrowed anteriorly ; shoulders somewhat
