OF NEW ZEALAND. 213 



coxa are sub-globose and rather remote, the posterior almost contiguous 

 and sub-cylindric ; the/w- and mesosterna between the coxae are plane, the 

 metasternum elongate. The legs are of moderate length ; femora inflated 

 and rather deeply excised near the apex, which has thus a dentate 

 appearance, and grooved below for the reception of the tibia, which is 

 shorter than the femora, and gradually expanded towards the apex where 

 it is armed inwardly with two stout spines ; tarsi four-jointed, the apical 

 joint elongate and as long as the three basal ones conjointly; claws slender 

 and simple. The abdomen is not so long as the metasternum, and its 

 segments decrease in size. 



This genus is difficult to locate satisfactorily ; in some respects it 

 exhibits a similarity of structure to the Rhysodida, but the structure of 

 the tarsi forbids its association with the species of that group. I think 

 it should be placed next to Philothermus, so as to form a connecting 

 link between that genus and Rhysodes ; at any rate until the accumula- 

 tion of more specimens will admit of a thorough examination by entomo- 

 logists more conversant with the structural characters of this ill-defined 

 group. 



A. punctatum, n.s. Dark rufo-castaneous, moderately 

 shining, nude. Head punctulate and without other sculpture. Thorax 

 with an indistinct dorsal and other depressions, near the sides, its sur- 

 face finely punctate and flat. Elytra rather wider than and twice as long as 

 the thorax, with prominent shoulders, the sides nearly parallel and very 

 gradually narrowed posteriorly; disc depressed, with six indistinct, 

 shallow striae, which become quite obsolete towards the apex; these 

 grooves are more or less punctate, yet not very distinctly sculptured. 

 Legs finely punctulate. Antenna and tarsi pilose. Under side of head 

 and prosternum rugose, the rest finely punctured. 



Length, 3 lines. 



I found two examples at Parua (Whangarei Harbour.) 



FAMILY RHYSODIDES. 



Mentum very large. Ligula coriaceous, bilobed. Maxilla with two 

 unarmed lobes. Antenna eleven-jointed, filiform, nearly always granular. 

 Head with a narrow neck. Elytra completely covering the abdomen. 

 Legs short or moderate ; the anterior and intermediate coxse globose, 

 embedded, distant ; posterior transversal ; hind trochanter projecting at 

 inner side of the femur ; tarsi pentamerous, simple, cylindrical. Abdo- 

 men with six segments ; the three basal connate. 



Rhysodes. 



(Illig.); Dalman, Anal. Ent., p. 93. 



Mentum connate, concealed, trilobed, the central lobe largest, sub- 

 ngular. Ligula soldered to the chin, rough, bilobed. Last joint of 

 theNriaxillary palpi sub-ovate and acuminate ; that of the labial oblong.
