Coxelus dubius, n. sp. 
C. oblongus, angustulus, parallelus, piceus, antennis pedibusque rufis, 
supra dense breviterque hispidulus, subvariegatus, subtus breviter 
griseo-setosus ; tibiis extus hispidulis. Long. corp. 2} m.m. 
Antenne short, red, 11-jointed, the basal joint scarcely visible from 
above; second a good deal larger than the following ones; third small, but 
distinctly longer than the following joints, the fourth to eighth being small, 
ninth small but transverse, tenth broad and transverse, eleventh short and 
not quite so broad as the tenth. Eyes bearing a few short coarse sete. 
Thorax about as long as broad, nearly as broad as the elytra, only slightly 
narrowed behind, and the sides very little curved towards the front angles ; 
the surface a little uneven, bearing short coarse sete or scale-like hairs ; 
the lateral margins densely fringed with such sete. Elytra apparently 
rather coarsely and closely sculptured, but their sculpture rendered indistinct 
by the dense short sete with which they are clothed ; these sete are a little 
variegated in colour; there are no tubercles or depressions. Head with 
rather long cavities beneath, directed backwards, so as to be parallel along . 
the inner margin of the eyes; sides of the thorax near the front angles 
slightly depressed, so as to indicate the rudiments of cavaties for the pro- 
tection of the antenne. Legs red; tibiw armed externally with fine short 
sete. 
Sent both from Auckland and Tairua by Mr. Lawson and Captain 
Broun. 
Obs. This species departs somewhat from the European Co.elus pictus, 
by the more elongate antennal cavities and by the slightly concave front 
part of the surface of the undersides of the thorax ; but its general structure 
seems to be so similar to that of the European species, that I think it 
would be premature to characterize it at present as a distinct genus. 
Co:xelus similis, n. sp. 
C. oblongus, angustulus, parallelus, piceus, antennis pedibusque rufis, 
supra dense breviterque hispidulus, vix variegatus; tibiis extus 
breviter pubescentibus. Long. corp. 21 m.m. 
This species is extremely closely allied to C. dubius, aud only differs 
therefrom, so far as I ean see, by the following characters :—The antennm 
and legs are a little stouter ; and the tibiz, instead of bearing externally 
coarse sete such as. are seen on the elytra, bear only a few fine hairs; the 
base of the thorax is less depressed, so that the outline at the junction with 
the elytra seems less interrupted.
