OF NEW ZEALAND. 621 



1089. A. Spatiosa, n.s. Body shining, pale rufo-castaneous ; the 

 dorsal portions of the thorax and elytra, as well as a rather large lateral 

 spot, in front of the middle of each elytron, testaceous ; the apical half 

 of the antennae is infuscate \ the legs are nearly of the same colour as 

 the sutural region of the elytra. The head is elevated behind and 

 between the antennae, and this raised portion has a distinct central 

 longitudinal depression, which terminates in line with the antennae, so 

 that it does not form a continuous dividing line ; immediately behind 

 the raised vertex is a row of punctures, the rest of the surface being 

 smooth. The thorax is quadrate, rather short, its sides but little rounded, 

 the anterior angles are obvious, and it is only moderately constricted 

 behind ; its surface is smooth and shining ; there is the usual transverse 

 basal depression, and, in front, two not very evident rounded foveae. 

 Though bearing a certain similarity of form to that of the typical species, 

 the thorax is more decidedly quadrate and less constricted behind the 

 middle. The elytra are oblong, their sides nearly parallel, and the apex 

 rounded ; there is a slight transverse depression near the base, and each 

 elytron has ten rows of coarse punctures, which are placed in feebly 

 impressed striae. The second tarsal joint is small. 



Length, 2 lines. 



Of this rather large species, I found six or seven examples at Parua, 

 Whangarei Harbour. 



Group EUMOLPID^E. 



Head moderate, more or less immersed in the thorax; forehead 

 plane or slightly convex ; epistome distinct, or not ; labrum transversal, 

 emarginate. Mandibles wide at the extremity, bi-dentate. Inner lobe 

 of the maxilla short, broad, membraneous ; the external slender, elon- 

 gate, and almost bi-articulate ; their palpi four-jointed, of variable form 

 and length. Under-lip with short mentum, hollowed in front. Ligula 

 semi-oval or sub-quadrate, furnished with tri-articulate feelers. Eyes 

 oblong, more or less sinuate at their inner margin. Antennae widely 

 separate, filiform or sub-clavate, never pectinate, about half the length 

 of the body. Prothorax conical, sub-cylindrical, or globose. Scutellum 

 always distinct, variable in form. Elytra short or elongate, oval or 

 cylindrical, entire, neither truncated or abbreviated. Prosternum trans- 

 verse or oblong, seldom narrow ; its episterna triangular, elongated 

 longitudinally ; front cotyloid cavities rounded. Legs ordinarily differ- 

 ing, sometimes approximating, the posterior sometimes widely distant. 

 Tarsal claws bifid or appendiculate, rarely simple.
