OF NEW ZEALAND. 34 1 



Length, i:|line. 



Obs. — I found three specimens near Whangarei Heads ; the one 

 I imagine to be the female has shorter antennae, with the larger joints 

 less angulated than those of the males. This and the two following 

 species may necessitate the formation of a new genus, differentiated 

 from Aiwbiiim by the peculiar structure of the antennae. 



621. A. granulata, //.-v. The description of ^. notata is appli- 

 cable to this species, so far as form and most structural details are 

 concerned, but the antennce of A. granulata are more robust, only the 

 fifth joint is much dilated, the large seventh, ninth, tenth, and eleventh 

 joints are at least twice as long as they are broad, and the sixth and 

 eighth joints are a little larger than the corresponding ones in A. 

 votaia. 



The body is of an infuscate-red colour, clothed with short yellowish 

 hairs, and the legs and anteim^e are of a clearer red than the body. 

 The thorax is a little longer than broad, convex, slightly constricted in 

 front of the middle, without any perceptible dorsal line, and so sculp- 

 tured as to appear covered with minute granules. The elytra bear 

 punctured striae and many minute granules. 



Length, \\ line. 



I found two examples near Whangarei Heads. 



622. A. sericea, n.s. Allied to the preceding species but smaller, 

 of a rich reddish-brown colour, with yellowish pubescence, giving the 

 insect a somewhat silky appearance ; the legs and antennae are reddish ; 

 the latter moderately slender, similar in structure to those of A. notata, 

 but with the joints relatively smaller. 



Frothorax a little longer than broad, transversely convex, slightly 

 contracted in front of the middle, its sculpture difficult to define, but 

 consisting apparently of closely placed rugose punctures ; its surface is 

 rather densely clothed, and the yellow hairs predominate on the middle 

 and near the sides. 



The elytra are more than twice the length of the thorax, and broader 

 than it, a little depressed at each side near the middle, and bearing 

 feeble but distinctly punctured strise ; they are somewhat variegated, the 

 yellowish pubescence forming irregular linear spaces along the suture, 

 but congregated near the shoulders and behind the middle so as to 

 form large spots. Legs rather short.

Whangarei Heads ; where I found two examples. What I suppose 

 to be the female is the larger of the two, with shorter and more robust 

 antennie. 



623. A. tricOStellum, JVhite .- Voy. Er. Terr.; Ins., p. 8. 

 Antennce very long, with the last eight joints filiform ; brownish, testace- 

 ous, covered above with a waved short golden silky pubescence ; each 

 of the elytra with three slightly raised longitudinal costse ; thorax nar- 

 rowest on the sides, somewhat rounded behind and slightly hollowed 

 down the middle.
