Artystona erichsoni, White (Titena). 
The Titena interrupta, Redtenb., must be referred to this species, the 
type specimens of which are in my collection. 
The head is remotely punctured; the prothorax more closely punctured, 
with the interstices quite smooth. 
Hab. New Zealand. Three examples in my collection. 
Artystona wakefieldi, n. sp. 
Readily to be distinguished from A. erichsoni by the colour entirely of a 
dark shining brown; the head and prothorax much more closely and 
rugosely punctured ; and, as a secondary character, the intervals on the 
elytra (especially at sides and apex) are more strongly interrupted and 
more distinctly tuberculiform. 
Length 5 lines, 
Hab. New Zealand. Five examples. . 
Examples of this species in Doué’s collection were labelled em 
volvulum, Klug.’’ 
* 
Artystona rugiceps, D. sp. 
Of the same colour as the preceding, but smaller; form decidedly less 
parallel; eyes narrower, appearing outwardly conical when viewed from 
above, a distinct space between their upper margin (which is entire) and 
the antennary orbits; these latter very convex, subangulately rounded: - 
head much more strongly rugosely punctured; the punctures larger, 
rounder, and deeper ; punctures on prothorax not more numerous than in 
A. wakefieldi, but larger, rounder, and deeper; the interstices not at all 
rugulose : elytra sculptured as in the preceding, but the form is elongate- 
oval, 
Length 83-43 lines. 
Hab. New Zealand. Seven examples. 
This is the species dispensed by Dr. Schaufuss under the name of 
“ Helops? porcatus,” 
Adelium zelandicum, n. sp. 
_ Oblong, subparallel, attenuate behind, depressed ; bronzed brown, more 
or less metallic. Head short, immersed up to the eyes in the prothorax, 
somewhat rounded in front; epistoma very short, convex, distinctly emar- 
ginate in front, the suture more or less distinctly marked, arcuate ; one or 
more impressions between the eyes ; rather strongly and somewhat irregu- 
larly punctured and rugose : labrum prominent, transverse ; angles strongly 
rounded, notched at apex: antenn emoderate, a little longer in male than 
in female, perfoliate (distinctly so in male), gradually thicker, and a little 
compressed outwardly ; the joints obconic, all longer than wide, three 
Shorter than four and five united, the last largest of all, obliquely rounded
