(372 COLEOPTERA. 



4258. Mecodema antennale sp. nov. 

 Nitid, black, legs and antennae piceous. 



Rather broader than M. cassense and, though very similar thereto, 

 differing in having only a single groove alongside each eye. The antennae 

 are notablv thicker. The basal fossae of the thorax are deeper, more 

 elongate, and extend to the base, where they are more definitely marginate. 

 The sixth elytral striae are deeper than the inner ones but are not as 

 distinctly punctured as those of M. cassense, and the seventh interstices 

 are sometimes coarsely tripunctate. The last abdominal segment has only 

 four apical punctures. 



Length, 24 mm. ; breadth, 7| mm. 



Gordon's Pyramid, Mount Arthur; 4,500ft. Found by Mr. A. C. 

 O'Connor on the 13th January, 1918. 



4259. Mecodema longicolle sp. nov. 



Elongate and narrow, slightly convex ; nitid, black, antennae and 

 tarsi piceous, palpi more rufescent. 



Head, including the prominent eyes, nearly as broad as thorax, 

 irregularly rugose near the eyes, with numerous moderately coarse punc- 

 tures behind them, the frontal longitudinal grooves dee]) ; labrum rather 

 short. Thorax almost as long as broad, its sides only slightly rounded, 

 narrowed, but not at all abruptly, towards the obtuse hind angles, its 

 base medially emarginate and obliquely curved outwards, lateral channels 

 slightly expanded behind the middle, the margins obsoletely crenulate, 

 apex subtruncate ; disc finely irregularly transversely striate, the apical 

 and basal longitudinal striae indistinct, the central groove well marked 

 and very nearly reaching both base and apex, posterior foveae small and 

 shallow, situated close to the angles. Elytra elongate-oval, 2| times the 

 length of thorax, a fifth broader ; moderately subseriate-punctate, some 

 of the punctures rotundate, others elongate, the usual smooth lateral space 

 on each somewhat indefinite. 



Underside shining ; flanks of prosternum moderately closely punctate, 

 basal segments of the abdomen with a few shallow punctures, the 

 terminal finely transversely striate and, at the extremity, with a pair 

 of punctures on each of the middle ; mesosternum densely rugose-punctate. 



Antennae distinctly pubescent from the fifth joint onwards. Anterior 

 and middle tibiae slightly prominent at the outer extremity. 



This, though somewhat similar to Sharp's M. metallicum (1760), a 

 Greymouth species, may be at once separated therefrom by the absence 

 of any well-marked basal contraction of the thorax, which, moreover, in 

 1760, has nearly straight sides, and by its longer and more coarsely 

 sculptured elytra. 



Length, 17 mm. ; breadth, 5 mm. 



Mount Egmont. A single damaged individual, found by Mr. G. V. 

 Hudson at an elevation of 3,000 ft. 



4260. Mecodema philpotti sp. nov. 



Elongate, moderately convex and nitid ; black, antennae and legs 

 piceous, palpi with rufescent tips. 



Head, excluding mandibles, almost as long as thorax, not much narrower, 

 nearly smooth along the middle, each side broadly longitudinally depressed 

 and evidently irregularly rugose, the frontal sulci well marked, those 

 near the eyes somewhat irregular ; the transverse area behind the 

 eyes is rather closely and moderately finely punctate, the occiput feebly
