184 Capt. T. Broun on new 
broadly, but not deeply, impressed near each side. Antennal 
cavities large at the point of insertion, the groove along the 
inner side of the eye rather narrow. 
This genus may be placed near Heterargus and Tarphius. 
The eyes are larger than those of the former, the mentum is 
much smaller, all the coxe are less widely separated, and the 
prosternum and epipleuree differ. 
Protarphius ruficornis, sp. n. 
Oblong, convex, covered with greyish-yellow sappy matter, 
rufo-fuscous ; antenna, tarsi, and palpi yellowish red; legs 
infuscate. 
Head small, immersed nearly to the eyes, about half the 
width of the thorax, with a few small granules and fine yellow 
sete, the prominences over the antennal insertion not extending 
laterally beyond the eyes. Antenna short; first joint thick, 
only its extremity visible from above; second stout, hardly 
longer than broad; 3 to 9 slender, third distinctly longer than 
fourth, 5 to 9 bead-like, the ninth scarcely larger than the 
eighth; club pubescent, large and compact, its basal joint 
large and transverse, thrice the breadth of the ninth, the 
terminal slightly longer than the basal one, but hardly as 
broad as that is. Thorax transverse, its sides somewhat expla- 
nate, but little curved, not serrate, abruptly contracted or 
notched close to the base; apex medially rounded, with a 
sinuosity inside each of the obtuse angles ; the surface uneven, 
with five impressions and intervening elevations, its sculpture 
granular. /ytra oblong, of the same width as the thorax, 
the apical portion narrowed and nearly vertical; on each 
elytron there is a moderately elongate basal elevation, in line 
with this there are two nodosities, the larger one is on the 
top of the apical declivity, there is another series near the 
side; between the suture and the side there are four series of 
closely-placed punctures, the interstices are more or: less 
transversely rugose. Legs rather short; ¢dve but little 
curved, with fine yellow setz, like those on the body. 
Underside rather plane, ruto-fuscous, with granular sculp- 
ture and fine sete. Abdomen with deep broad sutures. The 
side of the prosternum bears five or six denticles which are 
not visible above. 
Length 7, breadth nearly 4 line. 
Mount Pirongia. Two examples, Dec. 1892. 
Obs. No. 1167 may be placed in this genus; the tarsi, 
however, are more elongate and slender, and the eyes are 
larger and more prominent.
