TROGOSITIDAE. 389 



Length. 4J-5 mm. ; breadth, 2 mm. 



Point Hill, near Mount Algidus. 0)ie from Mr. T. Hall on uv 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 tliorax 

 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 subrectangiilar 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 joints 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, 4| mm. ; breadth, l|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, sUghtly 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 irregiilarlv 

 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 Jiearly twice 

 as broad as long, apex deeply emarginate, the base bisinuate ; sides fuiely 

 margined, shghtly 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 obUquely 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 is 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 extremitv, tarsi nmch 

 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.
