332 COLEOPTERA 



Long., vix 4 mm. ; lat., ij mm. 



Antenna short and rather slender, but with a rather broad short 

 club, the tenth joint being strongly transverse, and the eleventh rather 

 stouter than the tenth, and hardly so long as broad. Head about as 

 broad as the elytra, with a large triangular impression behind the labrum. 

 Thorax sub-cylindric, but a little dilated in the middle, about as long as 

 broad ; it, as well as the head, is without punctures. Elytra very 

 narrow, but with the shoulders well marked ; they are marked by broad 

 obsolete grooves, without punctures. Legs very long.

603. P. debilis, Sharp ; Ent. Mon. Mag., May, 1877. Angus- 

 tulus, nitidus, parcissime pubescens, testaceus, elytris sutura late, pro- 

 thorace capiteque vage, fusco-signatis ; elytris suturam versus indiscrete 

 punctatis ; abdomine et pectoris lateribus fuscis. 



Long., 5 mm. ; lat, ij. 



Antenna short and rather slender, third joint a little longer than 

 fourth, nine to eleven slender but broader than the preceding joints, 

 nine and ten each about as long as broad, eleventh rather longer than 

 tenth, a little longer than broad. Head, including the very prominent 

 eyes, rather broader than the thorax, of a yellowish or tawny colour, 

 obsoletely punctured. Thorax about as long as broad, considerably 

 narrower than the elytra, constricted in front and behind, with some 

 indistinct dark marks along the middle, its sculpture indistinct, consist- 

 ing of indistinct depressions. Elytra narrow and parallel, with the 

 shoulders well marked and rectangular; they are shining and of a 

 yellow colour, with a broad irregular dark mark extending down the 

 suture ; they bear a very few fine upright hairs, and have indistinct large 

 punctures near the suture. Legs entirely yellow. 



A single individual, which was found, I believe, at Christchurch, has 

 been given me by Mr. Wakefield. 



NOTE. I have a specimen from Captain Hutton, which he had 

 found in Otago ; it has pale-green margins to the elytra, the streak 

 intervening between the green and dorsal fuscous mark is pale-testa- 

 ceous, and they bear shallow, somewhat rugose, impressions; the sculp- 

 ture of the thorax also is rather rugulose; but I can scarcely consider it 

 more than a variety. 



Balcus. 



Sharp ; Ent. Mon. Mag., May, 1877. 



Antenna with a three-jointed very loosely articulated club; the labial 

 palpi with the terminal joint very large ; that of the maxillary also 

 dilated and securiform. Eyes large and prominent, finely granulated, 

 slightly emarginate in front. Posterior coxa only slightly separated. 

 Tarsi rather large, apparently only four-jointed, the basal joint being 

 atrophied above and below, the second, third, and fourth joints with 

 large bilobed membranes, the claws simple. In form the insect is 

 rather like Thanasiimis formicarius, and maybe placed near that species,
