OF NEW ZEALAND. 885 



small basal foveoe, and a largo cavity at each side behind, its sculp- 

 ture like that of the head. Elytra broader than thorax, oblong, 

 sutural striae deep, the intra-humeral impressions extend half-way 

 from the base with half a dozen punctures in each. Hind-body as 

 long and as broad as elytra ; its three basal segments parallel and 

 marginated, the apical ones shorter and deflexed ; the base of the 

 first covered with minute brassy scales and short depressed hairs 

 beyond ; the second deeply excavated nearly from one side to the 

 other, with a basal protuberance directed towards, but not touching, 

 a small median raised space on its hind margin ; third segment quite 

 as large as second, convex ; the clothing and punctation similar to 

 those of the elytra. Legs moderately slender, the four anterior 

 tibiae straight inwardly and curved externally ; the posterior 

 slightly bent at the extremity. 



The extraordinary second dorsal segment of the abdomen is quite 

 without precedent. 



Length, nearly i-J- lines ; breadth, nearly f . 



I found one under bark in the Paparoa district, south of Auck- 

 land. 



I 575- S. Slllcator, n.s. Elongate, shining, elytra and legs 

 fulvous, head, thorax, and antennae red, hind-body castaneo-rufous, 

 palpi yellow. 



Head smooth, rather flat, rounded behind, with a deep obvious 

 groove extending from between the antennal tubercles to the occiput, 

 and without other distinct impressions. Prothorax cordiforrn, 

 slightly broader than head, with large post-median and lateral 

 cavities, and two minute basal foveae. Elytra short, but little longer 

 than thorax, much narrowed towards the base, with distinct sutural 

 and intra-humeral furrows, these latter rather short and entire. 

 Hind-body elongate, its third segment broader than elytra, the three 

 basal of about equal length, all large, the others shorter and 

 attenuated, but not much deflexed ; clothed like the elytra with 

 conspicuous yellow hairs. Legs and antennae of normal structure, 

 but with the posterior tibiae bent near the extremity. 



This is the only species in which the frontal cavity extends from 

 the antennal tubercles to the back part of the head. The body is 

 rather elongate, and is contracted between the head and thorax, 

 the thorax and elytra, and again, but less evidently, at the first 

 dorsal segment of the abdomen. 



Length, i J lines ; breadth, J. 



I found my specimen at Woodhill, on the Kaipara Railway, near 

 Helensville. 



1576. S. OSClllans, n.s. Shining, chestnut-red; the elytra, 

 limbs, and trophi paler, head and thorax nearly nude, the rest of the 

 body hirsute. 



Head short, almost as broad as thorax, obtusely dilated behind 

 the eyes, but not angulated behind nor rounded laterally ; its median 

 cavity deep and extending as far as the back part of the eyes ; hind 

 foveae small and narrow, Antenna thick. The maxillary palpi
