OF NEW ZEALAND. 257 



The head and thorax are moderately closely but not at all deeply 

 punctured, the punctation of the latter denser near the front angles 

 than elsewhere, leaving an almost smooth dorsal line with a depression 

 at its base ; there are two rounded impressions on the middle (one near 

 each side), and in front of these two others close to the margins ; irts~ 

 much broader than long, a little convex, emarginate in front, nearly 

 truncate at the base, its sides behind are almost straight, but in front are 

 obliquely narrowed to the prominent angles. The elytra are short, of 

 the same width at the base as the thorax, rounded laterally, and a good 

 deal narrowed and sinuated behind, where they are abruptly deflexed, 

 not protruding beyond the pygidium, but leaving it exposed below ; 

 their upper surface is defined by a sharp rim, and the epipleurse by 

 another but finer one, and between these are two obvious striae ; each 

 elytron has six impunctate striae ; the disc is elevated, so that the base 

 seems to be a good deal depressed. 



The underside is shining black and rather distantly punctured, with a 

 few granules on the anterior portion of the metasternuin. 



The front tibia are long, rather suddenly bent and thickened near 

 the extremity, with two rows of punctures ; the intermediate are slender 

 at the base and a good deal dilated apically, and being short are some- 

 what triangular in form ; the posterior are long and flexuose. 



Length, 2 lines ; breadth, i \. 



Allied to the typical species, but differing from it in the sculpture of 

 the prothorax and metasternum, and in its more glossy upper surface. 



I found one example recently (October, 1878) at Whangarei Heads. 



Group-APHODinXE. 



Organs of the mouth sometimes entire, occasionally incompletely 

 overlapped by the clypeus. Ligula membraneous, nearly always bilobed. 

 Lobes of the maxilla coriaceous, unarmed ; sometimes corneous, den- 

 tate and ciliated. Mandibles and lab'rum of variable structure, concealed 

 by the clypeus among the greater number, visible among the lesser. 

 Antenna inserted under the clypeus, composed of nine joints, their club 

 of three short thick joints. Abdomen with six ventral segments, all free. 

 Middle pair of coxa oblique, contiguous behind. The metathoracic 

 parapleurcE simple. 



Aphodius. 



Illig. ; Lacord. Hist, des Ins. Coleop., Tom. iii.,/. 115. 



Mentum quadrate or trapezoidal, more or less hollowed in front. 

 Ligitla bilobed. its lobes penicillate. Last joint of the labial palpi 

 obconical, long, or a little shorter than the second ; the second and 

 fourth joints of the maxillary palpi the longest, sub-equal, the latter sub- 

 cylindrical. Mandibles lamelliform, horny-membraneous, hidden of the 

 cavity of the mouth, their molar tooth larnellated, horny ; lobes mem- 

 braneous, the external large and rounded, the inner small and trigonal. 

 Head a little convex, transversal, half-circular, and frequently sinuated
