410 Suarp—On New Zealand Coleoptera. 
to the fact that the sides of the elytra are more deflexed, they appear at first to be 
fewer. There is but little difference in the front tarsi of the two sexes.

Adelium intermedium, n. sp.—Oblongum, subdepressum, nigro-zneum, parum 
nitidum, antennis fuscis, tarsis rufis; prothorace subquadrato, subtiliter marginato, 
crebre subtiliter punctato ; elytris crebre punctatis, obsolete striatis. Long. 8 m.m. 
This greatly resembles A. zealandicum, but is much less densely punctate, and 
the fine depressed pubescence of that species is represented in A. intermedium by ¢ 
setosity that is so extremely minute that it can be only detected with a high 
power, the strize are quite as obsolete as they are in A. zealandicum. 
Bealey. Helms; a series of six examples. 
Adelium dunedinis, n. sp.—Oblongum, convexum, parum nitidum, eeneum, 
antennis pedibusque rufis, femoribus picescentibus; prothorace subquadrato, 
erebrius subtiliter punctato ; elytris subobsolete punctatis, ad basin seriebus minus 
regularibus punctorum paulo majorum. Long. 8 m.m. 
This has most affinity with A. simulans Redt., from which, however, it is 
readily distinguished by the much longer thorax, and by the fact that the serial 
sculpture of the elytra is confined to their basal half, and is even there more or less 
irregular. The thorax is fully one-fourth broader than long, the surface very 
closely and regularly punctate, with a definite punctiform basal fovea on either 
side, the lateral margin rather fine, the hind angles rectangular, but not sharply 
marked, the surface convexly transverse, especially in front, so that the front angles 
are much depressed, and the anterior margin seems comparatively less emarginate 
than in A. zealandicum, and many others. 
Dunedin. Another species we owe to Professor Hutton. 
Ceropo.us (noy. gen. Helopinorum). 
Corpus ovale, convexum, absque pubescentia. Pedes graciles, tarsi subtus sat 
longe pubescentes, articulo penultimo simplice precedente fere angustiore. Pros- 
terni processus latus, inter pedes impressus, apice libero; mesosternum declive. 
Antenne slender, the apical joints scarcely thicker, the third joint a little longer 
than the fourth ; antennary orbits a little elevated; basal joint of antenna partly 
covered above ; terminal joints of palpi securiform ; mentum rather broader 
than long; a little narrowed towards the base; the front oblique on each side, so 
as to form an angle in the middle; the surface not flat, the prominent antero- 
medial part being bulged: this apparently accommodates the hgula behind it, for 
this part is but little exposed ; front coxe rather small, rather widely separated ;
