SHarp—On New Zealand Coleopteru. 445 
Thorax rather elongate, with moderate lateral prominence, and two slight 
elevations in front of the middle, the pubescence more concentrated at the side 
behind the lateral tubercle. Elytra depressed, narrowed behind, the centro-basal 
tubercles moderately conspicuous, but not tufted, the surface behind them a little 
obliquely depressed, and also near the suture behind the middle longitudinally a 
little depressed ; they are more or less obscurely rufescent, exhibit a punctuation 
like the species of Hybolasius, and are clothed with griseous pubescence in a some- 
what spotty or irregular manner. 
Although very similar to P. medialis, this is readily distinguished by the longer 
thorax, and the absence of a definite medial fascia on the wing-cases. 
Picton, Helms; a series of twelve examples, unfortunately much abraded, varying a good deal in 
size and in the colour of the derma, which is sometimes more rufescent than black. 
'TETROREA. 
Tetrorea longipennis, n. sp.—Angustula, nigra, supra olivaceo-nigra, elytris 
pube pallida ornatis, pedibus antennisque rufescentibus, griseo-vestitis, fusco- 
maculatis ; thorace ad latera obtuse tuberculato, disco fortiter punctato, obsolete 
bi-tuberculato. Long. 10mm. (Plate xm, fig. 22.) 
I have seen only a single example of this insect; though similar to T. sellata it 
is much smaller, and is readily distinguished by the large extent of the pale patch 
of the wing-cases ; this extends backwards beyond the middle, becoming attenuate 
behind, and then expanding again, and ceasing a little before the apex. The 
thorax has but little pubescence, and is armed at the side with only a short obtuse 
angular prominence, and there are numerous coarse, deep punctures on the middle 
and two slight prominences. The elytra have a very obscure elevation of the 
surface on each side near the base; they possess numerous deep punctures on the 
basal portion; these extend backwards along the sides nearly to the extremity ; 
behind the termination of the pale portion there is a minute elevation, covered with 
dense black velvety pile ; the posterior part of the pale colour is defined in front by 
a minute line of black pile, and there is an obscure obtuse elevation behind the 
middle, near the suture. The slender basal portion of the femur, unlike the other 
parts, is not maculate.
