Coleoptera of Neiu Zealand. 23 



similar to that oi Ear in is, as is also the thorax — oblong, Avith 

 an angular dilatation in the middle of each side. The head 

 and thorax together are small relatively to the rest of the 

 body. The antennee ( $ ) are not much more than three fourths 

 the length of the body. 



Gastrosarus nigricollis, n. sp. 



O. violaceo-nigra, nitida ; ore, pedibus, abdomiue et elytris fulvo- 

 testaceis, his apice violaceis. Long, 5| lin. $ , 



The head is sparingly but strongly punctured, except the 

 middle of the crown, which is convex and glossy. The thorax 

 is small, very faintly punctured, and with a transverse de- 

 pression near the anterior and posterior margins. Each elytron 

 tapers gradually from base to apex, the latter being broadly 

 and sharply truncated, and not reaching the tip of the abdo- 

 men ; the surface is glossy, and bears only a few punctures, 

 strongest near the base.

Ehurida sericea, White, Cat. Long. Col. Brit. Mus. p. 299. 



Waypa River. 



The type specimen of this insect in the British Museum has 

 no resemblance whatever to E. sublineata, with which White 

 associated it, and which has been found to belong to Didymo- 

 cantha. E. sericea has finely faceted eyes and broadly angu- 

 lated anterior acetabula, and w411 therefore find its proper place 

 in the Callidiince ; it will probably remain a distinct genus, 

 but I am doubtful whether White's name can properly be 

 applied to it. 



Tlylotrupes bajulus, L. 

 Two specimens taken by Mr, Lawson at Auckland, differing 

 in no respect from the European insect. Evidently introduced.
