Lewis — On New Zealand ^oleoptera. 203 



are strongly striated longitudinally. The basal foveae are 

 punctured. The elytra have each nine striae almost without 

 punctures. The alternate interstices are twice the width of 

 the intermediate, and, with the exception of some scattered 

 punctures, are without sculpture. The underside of the head 

 (except the gula), the flanks of the prothorax, and the meso- 

 sternum are rugosely sculptured. The abdomen is sparingly 

 punctured. The intermediate tibiae are strongly punctate, as 

 are the front on the apical half of their inner face. Length, 

 16 mm. 



West Plains, Invercargill ; Mr. A. Philpott. 



This species may be readily distinguished from the others 

 of small size by the almost simple striae of the elytra. 



Lucanides. 

 Lissotes acmenus, n. sp. 



$ . Head and thorax black, shining ; abdomen shining- 

 brown. Head finely and obscurely punctured, most densely 

 on the vertex; the hind angles prominent. That portion of 

 the side margin that encroaches on the eye is more prominent 

 than in helmsi. Prothorax transverse, wider than the elytra, 

 finely and distantly punctured ; not so broad in proportion to 

 its length as in helmsi; with a fine medial line and three 

 punctiform impressions, one in the middle of the medial line, 

 the other two midway between that point and the side margin. 

 Its shape is similar to that of helmsi, but the base is more 

 markedly sinuate. Elytra short and broad, shining, each with 

 four obscure costae, which are more finely punctate than the 

 intervals between them. The margins of the thorax and elytra 

 and the four hind tibiae externally are clothed with short 

 golden setae, indistinct traces of which are sometimes seen on 

 the elytral costae. The mandibles are exactly similar to those 

 of smaller specimens of helmsi. Length, including mandibles, 

 20-25 mm. 



The female will probably be very similar to the same sex 

 of helmsi. 



This fine beetle is very closely allied to both helmsi and 

 aviulus ; indeed, Dr. Sharp considers that it is identical with 

 the former species. It is sufficiently easily distinguished by 

 its bright appearance, narrower form, and the smaller size of 

 fully developed individuals. I am indebted to Mr. G. Howes, 

 Invercargill, for a good series of males. 



As a first step towards a revision of the catalogue, I would 

 suggest the following synonyms as extremely probable : — 



Cicindela dunedxnensis, Castelnau = C. wakefieldi, Bates. 



Mecodema crenaticolle, Eedtenbacher = M. lineatum, 

 Broun. 



Dryocora hoivittii, Pascoli = Adelostella jjunctatum, Broun.
