8/8 COLEOPTERA 



the others, the third with three, the seventh \vith four or five large 

 punctures; h\teral sculpture normal. 



Vv'hen compared v.ith T. teniukensis and T. sylvius it will be seen 

 that the marginal channels of the thorax are^not expanded pos- 

 teriorly, that its sides are more deeply and suddenly incurved behind, 

 and that the elytra are more decidedly oblong. The deep well- 

 defined furrows of the wing-cases, together with their distinct and 

 regular punctation, are quite distinctive. The female is rather longer 

 and the hind-body relatively narrower than in the other sex.

I possess one pair collected by Messrs. T. F. Cheesemau and 

 A. T. Urquhart on the mountains in the vicinity of Lake Tekapo ; 

 elevation 2,500ft. to 6,500ft. 



Obs. — The same gentlemen brought to me from the Otira Gorge 

 a perfect male specimen of Trichosternus enysi. In it the posterior 

 thoracic angles appear slightly more prominent than in the much- 

 mutilated type ; the middle thighs are not only much swollen or 

 subdentate below, as if notched near the extremity, but the tibiae of 

 the same pair are somewhat laterally compressed and expanded, and 

 rather pointed at the apex. In the female the punctation of the 

 elytral stria3 is finer, and the interstitial punctures seem almost 

 obliterated. The marginal channels of the thorax are widened 

 behind, and the basal fossae being curved outwardly give a some- 

 what flattened aspect to these parts. 



1562. T. CnrvipeSj w.s. Oblong, moderately convex, shining, 

 black tinged with green, the latter colour most apparent on the 

 depressed parts ; legs pitchy-red, the tarsi and palpi paler, the latter 

 v/ith rufe scent tips. 



Head with irregular wrinkles on its vertex, and coarser longitudinal 

 ones between the frontal foveas ; eyes prominent, the post-ocular 

 parts not distended.. Prothorax large (nearly 3 X 2-| lines), broader 

 than long, widest at the middle, a good deal rounded anteriorly, 

 not greatly narrowed behind, wdth a moderate sinuosity just before 

 the slightly projecting angles ; apex ciliated, arcuate-emarginate ; 

 base widely but not deeply incurved at the middle ; disc moderately 

 convex, median furrow deep throughout, lateral rims fine in front, 

 widened and flattened behind ; marginal channels expanded pos- 

 teriorly ; basal fossae rather narrow ; with some fine rugae, those in 

 front longitudinal. ScuteUinn smooth behind. Elytra oblong-oval, 

 shoulders prominent, punctate-striate, the punctures fine ; interstices 

 a little convex, third, fifth, and seventh broadest, the seventh with 

 five or six large punctures. Legs robust ; femora incrassate, but not 

 dentiform underneath; posterior tibiae considerably curved out- 

 wardly. Underside black, the head and sides more or less impressed 

 with fine irregular lines. 



This is the only described Trichosternus wdth distinctly bent hind 

 tibiae.

One broken specimen was picked out of a miscellaneous collec- 

 tion sent from Taieri by Mr. S. W. Fulton.
