inwards from the shoulder ; the space in front of this slightly and obtusely 

 elevated ; there are some obsolete striae on the disc ; the punctation is 

 like that of the thorax. 



According to its description, T. serrigerum, 426 in tlie New Zealand 

 list, must be somewhat similar, but the clothing and sculpture must be 

 very different. I have not seen the insect itself. 



Length, 5-5J mm. ; breadth, 2J mm.

Group Aphodiidae. 

 Aphodius Illiger. Man. N.Z. Coleopt., p. 257. 



67. Aphodius sulcatissimus sp. nov. 



Parallel, oblong, moderately convex, nitid, glabrous, nigrescent, margins 

 of head and thorax and the legs rufous, elytra sometimes slightly rufescent, 

 tarsi and antennae fulvescent. 



Head unarmed, forehead deeply medially incurved ; the broad margms 

 end abruptly just before the flat hardly discernible eyes ; it is not quite as 

 broad as the thorax ; its punctation minute and distant in front, becoming 

 closer and coarser behind. Thorax transversely quadrate, only slightly 

 broader than long, lateral margins well developed in front, sides nearly 

 straight, posterior angles rounded ; the whole surface finely and distantly 

 punctured, the basal half of the disc, however, has numerous coarse scattered 

 punctures. Scutellum narrow. Elytra oblong, with acutely prom.inent 

 spiniform shoulders ; apices broadly rounded ; each elytron with 6 deep 

 dorsal striae, the distinct punctures at the bottom of these are evidently 

 separated from one another, the 3 external ones are not so deep ; interstices 

 minutely punctate, those near the suture are moderately broad, the others 

 are narrow and almost cariniform. 



Anterior tibiae tridentate externally ; the terminal spur of the inter- 

 mediate and posterior equals in length the basal two joints together of the 

 tarsi ; the second, or inner, spur is shorter. Pygidium vertical, subconical, 

 with a median punctiform fovea at its base. 



Underside nitid, blackish ; prosternum closely, the metasternum and 

 abdomen rather finely and distantly, punctured ; the base of segments 2-5 

 with a transverse series of very coarse punctures, so as to appear crenulate ; 

 the basal segment is subcarinate in the middle. 



The mimistakably spiniform humeral angles, profound elytral striae, and 

 subcarinate outer interstices separate this from all the New Zealand species 

 except A. fortipcs, 1721 ; in it the sculpture of the head is different, the 

 shoulders are less prominent, and the elytral interstices are rather broader. 



Length, 3| mm. ; breadth, IJ ram.

Group Melyridae. 



Dasytes PaykuU. Man. N.Z. Coleopt., p. 329. 



70. Dasytes pittensis sp. nov. 



Narrow, elongate, dilated posteriorly, subopaque ; pubescence scant}^, 

 minute, and greyish ; dark blue, legs and antennae piceous, 2nd joint of 

 these latter somewhat rufescent.
