OF NEW ZEALAND. 937 



Scutellum transversely triangular. Elytra about double the breadth 

 of the thorax, oblong-oval, moderately finely sulcate, the striae not 

 very perceptibly (if at all) punctured ; third interstices bi-punctate, 

 no visible median punctures. 



Allied to the preceding species, but rather larger and more oblong, 

 the sides of the thorax and wing-cases less curved, elytral striae more 

 obvious, thorax differently sculptured. The female of No. 1145 

 (0. patulus) makes a near approach to this species in form and~size, 

 but the thorax, as regards shape, most nearly resembles that of 

 No. 1339.

 Anchomenus (p. 20). 



1686. A. adamsi, n.s. Body rather elongate, somewhat 

 convex, not very glossy, pitchy-black, legs fusco-rufous ; tarsi, palpi, 

 and antennae ferruginous. 



Head oviform. Prothorax moderately small, apex widely 

 emarginate, base almost truncate, a good deal rounded laterally, 

 almost angulated just before the middle, considerably sinuously 

 narrowed behind, posterior angles rectangular, the sides just before 

 the angles nearly or quite straight ; disc convex, bearing feebly- 

 impressed undulating striae, dorsal groove well marked, basal 

 depressions prolonged forwards, lateral margins explanate and 

 reflexed. Elytra oviform, strongly obliquely sinuated apically ; 

 deeply sulcate, impunctate, interstices broad. Tarsi grooved above, 

 those of the male not much dilated. 



Very much like A. parabilis, but the base of the thorax is not 

 obliquely truncated towards the angles, and the elytral striae are 

 simple. 



Length, 6 lines ; breadth, 2^. 



Taranaki, base of Mount Eginont, elevation under i,oooft. 

 Named after Mr. I. Adams, B.A., who first found it. I found another 

 on the Waitakerei Eange, Auckland, at about the same elevation. 



OBS. No. 42 is congeneric.

Trichosternus (p. 3 1 )- 



1687. T. virens, n.s. Oblong, moderately convex, shining 

 green, legs and antennae rufo-piceous, tips of palpi paler. 



Protlwrax transversely quadrate, apex widely, base medially 

 incurved ; sides well rounded, moderately narrowed behind, posterior 

 angles rectangular, not projecting. Elytra distinctly striate, the 

 punctation of the striae small but distinct ; interstices a little convex, 

 the third with three, the seventh with five or six punctures. 



When compared with T. fultoni it will be seen that, although the 

 form and sculpture are nearly similar, it is rather more convex and 

 of a more uniform green colour above, and that the legs are less
