454 COLEOPTERA. 



Scape similar to that of A. sternalis, 2iid joint of funiculus more elon- 

 gate, slightly longer than the 1st, 3rd and 4th subquadrate, 7th broader 

 than 5th oi' 6th ; club ovate, triarticulate. 



Underside picet)us, 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 foi'in this more nearly resembles the smaller A. hicristatus (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), 4 mm. ; breadth, 2| mm. 



Routeburn, 13th February, 1914, one ; HoUyford, 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 

 disc 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. nodigenis, but with simple 

 instead of angulate anterior femora. 



Underside piceous, the last 3 segments reddisli, thinly clothed with 

 distinct yellow setae ; very irregularly punctate, 2nd segment with a trans- 

 verse series of rather coarse punctui'es behind, 5th closely punctate ; basal 

 segment large, subtruncate and broadly impi-essed in front, rather distantly 

 punctured there, its apical suture apparently sinuate but very indefinite. 

 Rostral canal and metasternal cavity like those of A. steinalis. 



The peculiar form and scanty vestiture are unmistakably different from 

 dui' allied species. 



Length (rostrum exclusive), 3| mm. ; breadth, 2 mm. 



Ben Lomond. Found among.st decaying leaves on the giound, between 

 2,000 it. and 4,000 ft. in height, by Mr. T. Hall on the 7th March, 1914. 

 Evidently rare, and probably icpicsenting a distinct genus.
