630 COLEOPTERA 



Mr. Lawson. I hope the reception of other specimens may enable me 

 to make known its characters in a more complete manner. On com- 

 mencing my examination of it, I supposed it would prove allied to the 

 ErotyltdcE, but I do not now think this is likely to prove the case. 



1 105. A. pretiosum, >2.s. Very convex, almost hemispherical, 

 polished, very dark olivaceous, antennse, legs and palpi bright testaceous. 

 AntcnncB longer than head and thorax^ first joint large ; second shorter 

 than third but stout ; fourth rather longer than third ; fifth and sixth 

 equal ; seventh to tenth of nearly equal size, but distinctly larger than 

 the preceding joints ; eighth slightly smaller than seventh ; eleventh long 

 and rounded. Head small, somewhat rugose. Thorax strongly trans- 

 verse, accurately adapted to the base of the elytra, rounded and nar- 

 rowed anteriorly, the sides finely margined, the whole surface distinctly 

 punctured. ScidcUioii moderately large, sub-triangular. The elytra 

 have their shoulders a little narrowed, so that the outline just at that 

 part seems somewhat interrupted ; they are broader than the thorax, 

 rounded laterally and narrowed behind, with fine but distinct margins 

 and suture, their surface is rather closely punctured, some of the punc- 

 tures being much larger than the others. The tibi(B are considerably 

 longer than the tarsi, but not twice the length, are strongly arcuated, 

 and dilated externally towards the apex; the second tarsal joint is 

 shorter and narrower than the first and third, fourth normal. The 

 lower side of the body is punctate, the first and fifth ventral segments 

 are of nearly equal length.

I found two specimens at Tairua in the summer of 1876 ; the 

 species, though dissimilar to A. enigma, is undoubtedly congeneric with 

 it. Mr. Lawson's specimen of A. enigma was found under a stone at 

 Cabbage-tree Swamp, near Auckland, in my presence ; mine were taken 

 off foliage. 



1 106. A. punctatlllll, n.s. Body sub-hemispherical, quite nude, 

 of a shining black colour, antennre and legs infuscate. The antennce. 

 are rather long and slender, and reach beyond the base of the prothorax ; 

 basal joint stout, sub-pyriform ; second short ; third longer than the 

 adjoining ones ; four to six slender, and decrease in size ; seven to nine 

 nearly equal to one another and distinctly larger than the preceding ; 

 tenth larger than ninth ; eleventh largest. Head finely punctured ; eyes 

 coarsely facetted. Prothorax strongly transverse, almost imperceptibly 

 narrower at the base than the elytra ; the base is obliquely truncated at 

 each side ; its whole surface finely and regularly punctured. Scutellum 

 invisible, but indicated by the minute transversely-triangular excision at 

 the base of the elytra ; these are of the orthodox form, but each bears 

 nine rows of small punctures, in addition to an abbreviated sutural row. 

 The tibia', are longer than the tarsi, and externally curved ; the tarsi are 

 stout, with a very large sub-oblong basal joint, which is abruptly and 

 extremely slender at the point of insertion ; second small, almost 

 cordate ; third bilobed ; fourth rather longer than but scarcely one-
