OF NEW ZEALAND. 421 



The male of this species has a large apical joint to the maxillary 

 palpus, which is externally excised throughout its whole length, a form 

 essentially differing from that of S. lineata. 



Length, 5 lines. 



Discovered by Mr. Colenso according to White ; the above de- 

 scription applies to specimens which I found at Tairua. This is the 

 most slender of the New Zealand species at present known. 



738. S. latiuSCllla, n.s. The head is finely punctured, but in 

 front distinctly wrinkled. Prothorax rather long and convex, widest 

 near the front, the sides rounded in front and gradually narrowed 

 posteriorly ; it resembles the head in colour, being pale testaceous, but 

 reddish ; it is finely and closely punctured, with sparing pallid pubes- 

 cence. Scutellum small, triangular. The elytra are rather broad, dila- 

 ted posteriorly, apices rounded and not covering the pygidium ; each 

 bears four discoidal lines which are paler than the interstices, and of the 

 same colour as the two broad marginal streaks ; the three interstices on 

 the disc, and two narrow outer lines, are infuscate ; they are sculptured 

 like the preceding species, but exhibit a somewhat roughened aspect, 

 owing to the semi-erect pubescence with which they are clothed. The 

 antenna are finely pubescent, with the basal joint somewhat compressed, 

 and expanded towards the apex ; second joint very short ; joints three 

 to ten gradually decrease ; the eleventh shorter than the preceding 

 joints. 



The terminal joint of the maxillary palpi in the male is large and 

 sub-securiform, but rather short, with a short indistinct external excision 

 close to the apex. In what I believe to be the other sex, the same 

 joint is larger, and if it were not curvedly-truncated inwardly its form 

 would be almost triangular. 



This is a decidedly broader, more robust insect than those pre- 

 viously described, and the palpi are stouter. 



Length, 5 lines. 



I found two examples at Whangarei Heads. 



739. S. lineata, Fabritius (Dryops). Pale ochraceous, with a 

 thoracic dorsal line and a broad lateral streak on each elytron, fuscous ; 

 the head and thorax nearly nude, the elytra densely covered with short 

 decumbent pale yellow hairs. Head finely and distantly punctured, 

 with a depression in front of the vertex. The sculpture of the thorax is 

 very similar to that of the head, and its surface is a little uneven. The 

 elytra are very finely and rather closely punctured, but the punctation is 

 concealed by the pubescence. 



The terminal joint of the maxillary palpus is almost obconical, with 

 an external excision which does not reach the apex. 



Length, 8 lines. 



The above corresponds with a specimen received from Mr. C. M. 

 Wakefield, who found it in the Canterbury district ; the only individual 

 I found is of a rather shining reddish-testaceous colour.
