454 COLEOPTERA. 
Scape similar to that of A. sternalis, 2nd joint of funiculus more elon- 
gate, slightly longer than the Ist, 3rd and 4th subquadrate, 7th broader 
than 5th or 6th; club ovate, triarticulate. 
Underside piceous, finely squamose. Basal 2 ventral segments flat, 
closely punctured, the 2nd evidently shorter, its frontal suture sinuate ; 
5th longer than 3rd and 4th together, its punctation shallow, covered with 
fulvous scales, its apex truncate, 6th short but distinct. 
In form this more nearly resembles the smaller A. bicristatus (3636) 
than A. sternalis, but it has a broader rostrum and different sculpture, &c. 
A specimen was carefully scraped with the point of a needle so that the 
true sculpture could be ascertained and described. 
Length (rostrum exclusive), 4mm. ; breadth, 24 mm. 
Routeburn, 13th February, 1914, one; Hollyford, 19th February, 1914, 
three. Found by Mr. T. Hall amongst leaf-mould. 
3943. Acalles zenomorphus sp. nov. 
Elongate-oval, convex, dull piceous, antennae and tarsi fusco-rufous ; 
elytra rather thinly clothed with depressed, small, obscure greyish scales, 
but with some more conspicuous but not coarse ones near the base; the 
sides of the thorax covered with more elongate, slender, brassy scales, the 
dise with a few depressed ashy setae. 
Rostrum arched, stout, slightly expanded towards the base and apex, 
as long as the thorax ; indistinctly carinate along the middle, longitudinally 
rugose, more finely punctate and rufescent in front. Thorax slightly 
bisinuate at the base, a fifth broader than long, somewhat gradually 
contracted in front ; distinctly and irregularly punctured behind, quite dis- 
tantly, and a little nitid and reddish in front ; its broad median impression 
is deeper at the base, and divided along the middle by a rather broad smooth 
space, the apical and median pairs of nodosities are very obtuse and indis- 
tinctly crested. Elytra obovate, more than double the length of the thorax, 
of the same width as it is at the base, rather wider before the middle, gradu- 
ally narrowed towards the subvertical declivity ; they are only moderately 
substriate-punctate, the suture is somewhat elevated below the summit of 
the hind declivity, 3rd interstices finely crested at the base but without 
distinct nodosities, the 5th obtusely nodiform at or just below the top 
of the declivity ; near the sides, before the middle, they are indistinctly 
trinodose or crested. 
Antennae and legs similar to those of A. nodigerus, but with simple 
instead of angulate anterior femora. 
Underside piceous, the last 3 segments reddish, thinly clothed with 
distinct yellow setae ; very irregularly punctate, 2nd segment with a trans- 
verse series of rather coarse punctures behind, 5th closely punctate ; basal 
segment large, subtruncate and broadly impressed in front, rather distantly 
punctured there, its apical suture apparently sinuate but very indefinite. 
Rostral cana. and metasternal cavity like those of A. sternalis. 
The peculiar form and scanty vestiture are unmistakably different from 
our allied species. 
Length (rostrum exclusive), 33 mm.; breadth, 2 mm. 
Ben Lomond. Found amongst decaying leaves on the ground, between 
2,000 ft. and 4,000 ft. in height, by Mr. T. Hall on the 7th March, 1914. 
Evidently rare, and probably representing a distinct genus.
