TROGOSITIDAE. 389 
Length, 44-5 mm. ; breadth, 2 mm. 
Point Hill, near Mount Algidus. One from Mr. T. Hall on or about the 
20th October, 1913. 
3844. Grynoma pallidula sp. nov. 
Depressed, slightly nitid; labrum, forehead, thoracic disc, and basal 
2 joints of antennae light rufo-castaneous, elytra and sides of thorax 
paler ; palpi and club piceous, tibiae testaceous, tarsi infuscate. 
Head narrower than front of thorax, with close, coarse, shallow sculp- 
ture like that of G. clavalis. Thorax twice as broad as long, its sides 
explanate and slightly almost regularly rounded, with subrectangular basal 
angles; its sculpture similar to that of the head. Elytra thrice the length 
of thorax, moderately coarsely and closely subseriate-punctate. 
Pubescence grey, slender, rather short, suberect, evenly distributed, and 
’ intermingled with some upright, slender, fuscous setae, but along the sides 
the setae are white and elongate. 
Antennae rather short, 3rd joint elongate and longer than 4th, joints 
4-6 smaller yet longer than broad; basal 2 jomts of the club obconical, 
together rather longer than broad, the terminal elongate-oval. 
The light coloration is in marked contrast to that of other species, the 
elytral pubescence is more evenly distributed and, being of a less silvery 
hue, is less conspicuous than in the preceding species. 
Length, 44 mm.; breadth, 13 mm. 
Mount Alfred, north of Lake Wakatipu; height, 4,000 ft. The only 
specimen as yet known was found by Mr. T. Hall on the 4th February, 
1914. 
Group MELOLONTHIDAE. 
3845. Eusoma eximia sp. nov. Eusoma White. 
Oblong, subparallel, slightly convex, moderately nitid, variegate, with 
a few outstanding setae along the sides; fusco-testaceous, head piceous, 
more rufescent in front; thorax to a large extent but very irregularly 
aeneo-fuscous, elytral interstices more or less fusco-violaceous. 
Head moderately finely and sparingly punctured behind, more coarsely 
and with reflexed margins in front. Thorax in the middle nearly twice 
as broad as long, apex deeply emarginate, the base bisinuate ; sides finely 
margined, slightly wider near the middle than elsewhere, very gently 
rounded there and behind so that the obtuse posterior angles appear to 
be turned slightly inwards, more obliquely narrowed anteriorly ; its surface 
irregularly but not closely punctate, more finely and distantly near the 
middle and sides. Scutellum almost smooth. Elytra just thrice the length 
of thorax, not quite as wide as it 1s at the base, their truncate apices 
not wholly covering the pygidium ; they are moderately finely, though not 
very regularly, subpunctate-striate above; the 2nd, 4th, and 6th interstices 
are rather broader than the others, nearly flat, and have some coarse punc- 
tures, the suture is obtusely elevated throughout. 
Legs elongate, anterior tibiae bidentate near the extremity, tarsi much 
longer than tibiae. 
Underside testaceous, very thinly pubescent, femora with elongate setae. 
Basal segment of abdomen covered by the femora, 2-5 subequal, 5th with 
an angular apical depression, 6th with distinct slender setae and a trans- 
verse basal impression.
