OF NEW ZEALAND. 875 



oblong, v.-ith rounded hind-angles, very large, second transverse, of 

 moderate size. Antennce with, robust basal joint, second a little stouter 

 and shorter thaia third, joints 3-6 rather slender and about equal, 

 seventh and eighth broader than the preceding ones, ninth and tenth 

 still larger, these four longer than broad, eleventh largest. 



There is no probability of this being mistaken for the two pre- 

 viously-described ones of equal size f^l. pretiosa und punctata) ; the 

 thorax is less transversal, and the enormously-developed basal joint 

 of all the tarsi is quite exceptional. 



Length, if lines ; breadth, i^. 



I found two specimens on the Waitakerei Eange. 



1557- A. SObrina, n.s. Black, shining; legs and antennae 

 pale-brown. 



Head finely punctated, labrum reddish. Prothorax transversal, 

 very finely and distantly punctured, the sides and base nearly 

 smooth. Scutellum quite distinct, triangular, reddish. Elytra sub- 

 striate, each with about ten rows of punctures, the sutural not reach- 

 ing the middle ; the striaa are not quite regular, but the punctures 

 follow their course. 



Intermediate between A. monstrosa and A. punctatum : the distinct 

 scutellum and moderately-developed tarsi distinguish it from the 

 former, whilst the elytral sculpture and longer thorax differentiate 

 it from the latter.

I obtained my specimen on the Waitakerei.

1557-^- M. litoreum, n.s. Elongate, moderately convex, 

 shining, black, legs and antennae dark rufo-piceous, tips of palpi 

 rufescent ; body bearing many long ferruginous bristles.' 



Head with numerous fine punctures between the eyes, slightly 

 transversely wrinkled, irregularly rugose in front ; la^brum obtusely 

 rounded ; eyes prominent. Prothorax cordiform, sides obtusely 

 rounded, considerably yet not very abruptly narrowed behind, 

 posterior angles blunt, the anterior a little rounded; base and apex 

 ciliated, the former deeply, the latter more feebly arcuate-emarginate ; 

 marginal channels with a row of hispid punctures, dorsal groove 

 well marked and terminating in the curved frontal impression, the 

 disc with some transverse rugte least evident on each side of the 

 middle,' basal fossffi large and close to the angles, base somewhat 

 depressed. Elytra elongate-oval, each wing-case with eight finely- 

 punctured striae (besides the lateral sculpture, consisting of large 

 punctiform impressions becoming rugose posteriorly) ; the first, 

 third, fifth, seventh, and ninth interstices broader than the others, 

 the third, fifth, and seventh with from two to six large punctiform 

 impressions, the posterior sculpture confused and rugose. Legs 

 elongate ; anterior tibiae with shallow punctures along their inner 

 face, the outer extremity prolonged ; intermediate with many spini-
