OF NEW ZEALAND. 387 



688. A. intricatum, Bates. This species is allied to A. hullatum, 

 being a rather broad robust form, blacker in colour, not at all bronzed, 

 with the legs and antennae slightly reddened, particularly the apical 

 joints of the latter. 



The head is rounded, not deeply immersed, rather uneven and 

 distantly punctured. The prothorax is broader than long, emarginated 

 in front, slightly so behind, the sides are a good deal narrowed in front 

 and sinuated behind, so that they appear obtusely dilated near the 

 middle, the front angles are blunt, the posterior almost rectangular and 

 resting on the elytra ; the surface is uneven, with a rather shallow, 

 dense, somewhat rugose punctation, an indistinct dorsal groove, and two 

 or three broad curved grooves near the sides. Scutellion triangular. 

 The elytra are a little wider near the middle than elsewhere and attenua- 

 ted posteriorly ; their sculpture consists of many moderately elevated 

 oblong or oviform spaces of variable size, sometimes forming a long 

 irregular elevation not far from the suture, these bear a few fine 

 punctures. 



The front tibice are slender at the base and considerably angulated 

 inwardly near the middle, where they seem as if obtusely dentate, and 

 the middle pair are inwardly produced at the apex. 



Length, 5f lines ; breadth, 2\. 



I have recently received a mutilated individual so named from Mr, 

 C. M. Wakefield, from which the above description has been drawn up. 

 The species was found in Westland ; it may be readily enough identified 

 by the peculiar form of the front tibia. 



689. A. aucklandicum, n.s. This species, in general outline, 

 is quite dissimilar to the orthodox forms of the genus, owing chiefly to 

 its elongate aspect and the non-contiguity of the thorax and elytra, it is 

 however a true Adeliiim. 



Colour brown, very slightly bronzed, moderately shining ; antenna 

 rufo-testaceous ; legs obscure rufo-testaceous. 



Antenncc pilose, with the third joint scarcely so long as the fourth 

 and fifth taken together. Head moderately large, rounded, punctulate, 

 the punctation not very obvious ; labrum transverse, slightly emargina- 

 ted ; eyes transverse, oviform, coarsely facetted. Thorax small, some- 

 what convex, transverse, sub-quadrate, finely margined, the sides 

 rounded, apex moderately arcuated, base truncate ; it is narrower 

 behind than in front, the posterior angles obtuse, rounded, obsolete ; its 

 surface is nearly smooth, but a few shallow remotely-placed fine punc- 

 tures may be discerned ; owing to its non-contiguity to the elytra, and 

 its rounded hind angles and sides, the general outline of the insect has 

 an interrupted appearance. Scutellum large, transversely-triangular. 

 Elytra sub-convex, not much wider than the thorax, ovate, with obtusely 

 rounded humeral angles and slightly produced apex, before which there 

 is an elongate not very perceptible sinuation ; their sculpture consists of 

 nine fine striae, which are finely punctured, but become obsolete towards 

 the apex (in one or two of my specimens which I had previously 

 examined, the striae were very feebly impressed, and very narrow, mere 

 aciculate impressions), and the interstices plane. The surface of the
