370 COLEOPTERA. 
3816. Sympiestus frontalis sp. nov. Sympiestus Sharp, Man N.Z. 
Coleopt., p. 1006. 
Elongate, not parallel, slightly convex, shining; black, lateral margins 
of elytra, the legs, and mandibles rufo-piceous, antennae and tarsi fusco- 
rufous, palpi fulvescent. 
Head narrower than thoracic apex, not including the large prominent 
eyes; frontal impressions broad, rather shallow and finely punctured, 
extending from the front of the eyes to the forehead. Thorax subquad- 
rate, very slightly broader than long, base and apex subtruncate, the sides 
gently rounded to behind the middle, a little stmuate behind, with rect 
angular posterior angles; dorsal groove rather slender, not reaching the 
apex, basal fossae sulciform and elongate, the intervening space not quite 
smooth. Elytra oblong-oval, twice the length of thorax, rather broader 
than it is at the base; the 3 inner striae, on each, moderately deep, 
finely yet distinctly but not very closely punctured, the sutural one reaches 
the apex, the others do not, the outer striae become obsolete towards the 
side. 
Sharp’s S. syntheticus (1804), as well as S. oculatus (2439), and S. 
modestus (2655) are easily distinguishable by their long, deep, smooth 
frontal impressions, and S. ruficornis (1338) by its much less convex eyes. 
Length, 6mm.; breadth, 2 mm. 
Scarcliff, near Mount Algidus. A single specimen found by Mr. T. Hall 
on the 20th October, 1914.

3817. Demetrida sinuata sp. nov. Demetrida White, Man. N.Z. Coleopt., 
p. 64. 
Subdepressed, nitid; black, the forehead, mandibles, and most of the 
antennae ferruginous, basal joints of these last, the legs, and palpi more 
or less fulvescent. 
Head smooth. Thorax elongate, as long as broad, widest at or just 
before the middle, moderately rounded there, widely and distinctly sinuate 
behind, with acute almost prominent posterior angles; base subtruncate, 
a little oblique at each side; disc almost smooth, having only some obso- 
lete transverse striae, basal fossae prolonged as broad channels inside the 
reflexed margins almost to the apex, mesial groove not abbreviated, the 
apex subtruncate or only slightly emarginate. Elytra more than double the 
length of thorax, widest behind the middle, their curvedly narrowed 
shoulders wider than the thoracic base, apices somewhat oblique ; on each 
there is a well-marked basal puncture on the 2nd interstice, there are no 
perceptible scutellar striae, the indistinctly punctate dorsal striae are well 
marked near the suture, less so near the sides ; interstices almost flat, with- 
out discernible seriate punctation, the 3rd usually tripunctate. Pygidium 
finely punctate and pubescent. 
Underside shining, piceo-niger, with a few fine setae; coxae and tro- 
chanters fulvescent. 
Well differentiated from D. picea (125) by the more elongate thorax, its 
obviously sinuate sides and acute posterior angles, by the oblique elytral 
apices, less deep and regular striae, by the absence of scutellar striae and 
minute serial interstitial punctures. 
Length, 7-8 mm.; breadth, 24 mm.
