subscriate ])iiuctiitc, more irregularly at the base, .substriatc behind ; filth 

 iiterstices with, on each, an elongate raised plica ending in a .slight depression 

 before the middle, the remaining ])ortion continued backwards but less 

 elevated and bticoming obsolete near the extremity, there is another elongate 

 plica outside the first but farther from the base, the outer interstices are 

 slightly elevated and interrupted. 



Antennae longer than the head and thorax, stout, second joint small, 

 scarcely any longer than broad, 3-11 subequal, fourth not shorter than third. 



Underside coppery brown, with depressed, slender grey pubescence. 

 Basal ventral segment about as long as the following three united, subtrun- 

 cate between the coxae, fourth slightly incurved behind, in the middle 

 about half the length of third ; fifth paler, rather longer, somewhat bisinuate 

 at the apex, sixth as long, concave in the centre, broadly rounded behind but 

 not reaching the elytral apices. 



More elongate-oval than the type of the genus (1101), and at once dis- 

 tinguishable from it, as well as P. auiiquus, b_y4 its projecting posterior angles 

 of the thorax, which are like those of the larger P. rohuslifs (1103). 



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



Silverstream, near Wellington. One example, from Mr. A. C. O'Connor ;

 4253. Aphilon sternalis sp. nov. 



Convex, subrotundate, glabrous, shining ; aeneo-niger ; legs, antennae, 

 and palpi testaceous. 



Head finely and distantly punctate, obliquely bi-impressed behind. 

 Thorax not twice as broad as long, widest at the somewhat rounded base, 

 its sides finely margined, gradually but hardly at all curvedly narrowed 

 towards the subacute front angles, apex finely margined and distinctly 

 incurved, posterior angles acutely rectangular ; disc distantly and lightly 

 punctured, a])parently almost sinooth near the sides and base. Scutellum 

 triangidar, flat and smooth. Elytra just double the length of thorax, of 

 the same width as it is at the base ; distinctly but irregularly seriate-punc- 

 tate, the inner row on each scarcely extending beyond the middle, all become 

 less distinct bi'hind, almost obsolete in the female, interstices irregularly 

 and more finely punctured. 



Tibiae finely setose,- slightly curved externally, a little expanded towards 

 the extremity ; basal joint of all the tarsi evidently enlarged, that of the 

 anterior subcordate, the others more oblong, the penultimate bilobed. 



Antennae as long as head and thorax, basal joint stout, rather longer 

 than the next, joints 3-6 elongate and slender, the others gradually thickened, 

 eleventh largest, oblong-oval. 



Underside aeneo-niger, with some short, slender greyish hairs, which are 

 more numerous on the paler fifth segment. Mesosternum very short, 

 grooved across the middle, its front margin feebly angulate there. Meta- 

 sternum rather coarsely punctate ; sixth segment short and indefinite. 



The interocular impressions, smooth-looking thorax, and coarsely punc- 

 tured raetasternum, taken together, are distinctive.

Titirangi, Auckland. Mr. A. E. Brookes found a pair on the 3rd June, 

 1916, and retains the female.
