appearing when examined sideways to consist of rows of 
rather small punctures, which, however, do not form well- 
marked strie ; there are many small indefinite elevations as 
well; the third interstices, on the top of the hind slope, are 
rather broad and very slightly raised, and the sides of the 
summit are somewhat prominent ; two or three striz can be 
seen there. Z%bie straight, with paler and finer sete than 
the body. Antenne with outstanding slender sete ; the last 
three joints, however, are more densely and finely clothed ; 
the first joint is but little exposed above, second transverse, 
third not as long as the following three, fourth and fifth 
short, almost transverse, sixth rather smaller than the con- 
tiguous ones, ninth and tenth obconical, obviously larger than 
the preceding ones, eleventh largest, not acuminate. 
Underside piceous, with short yellow sete. Abdomen in- 
distinctly sculptured. Pleur@ much inflexed, broad, with two 
series of punctures, the row nearest the body consists of fewer 
punctures (and finer) than the other. The front cove are 
placed near the hind margin of the prosternum, so that the 
frontal portion seems elongate; it has some shallow coarse 
punctures and is only very slightly incurved in front. 
In LE. epacus the pleure are punctured all over. 
In the genus Pervatrum the eyes extend below the sides of 
the head; in Hdalus they do not, they are, in fact, quite 
small. In Mesopatrum the eyes extend downwards below the 
sides of the head and are then directed a little forwards.

Ohaupo, Waikato. Three, December 1892. 
Group Edemeride. 
Sessinia thoracica, sp. n. 
Shining, testaceous, very pale; the outer half of each 
elytron fuscous ; this dark streak does not, however, reach 
the lateral margin ; head and thorax glabrous, elytra densely 
covered with pale depressed hairs, 
Head very much narrowed and depressed behind, its pune- 
tuation fine and shallow. Thorax about one fourth longer 
than broad, feebly incurved medially at the apex; its frontal 
portion (nearly half the whole length) is as broad as the head 
(including the large eyes), and is rounded laterally ; the hind 
part has nearly straight sides, and appears as if it were 
abruptly contracted to about half the width of the other; the 
thickened basal margin is curved towards the sides; the 
surface is uneven, being broadly depressed at each side of the
