OF NEW ZEALAND. 867 



apparently free from punctures, interstices plane on the dorsum and 

 but little elevated behind, their punctation concealed by variegate, 

 principally piceous and greyish, scales. Intermediate tibicB armed 

 with a distinct median tooth on the outside. Underside clothed 

 with coarse grey hairs. 



Like P. rostralis, but with a longer and narrower snout. In that 

 species the middle tibiae are widely emarginated from the inner apex 

 to about one-fourth their length, the emargination terminating 

 angularly, but not toothed, on the outer edge ; in this species the 

 hollow is merely apical. 



Length (rost. inch), 2-^-3 lines; breadth, li. 



Mr. S. W. Fulton found this species near Outram. 



Tychanus. 



1545- T. quadratllS, n.s. Convex, sub-quadrate, longer than 

 broad, slightly glossy, infuscate-red, covered with small yellowish 

 scales and erect variegate setae, those near the apex and sides of the 

 hind-body blackish ; tarsi and antennae ferruginous. 



Bostrum as long as thorax, moderately arched, slightly thickened 

 and squamose at base, its apex rugose-punctate, from thence to the 

 base tri-carinate. AntenncB inserted near the apex ; scape slightly 

 thickened and barely reaching the eye : funiculus more elongate, 

 first joint largest and clavate at apex, second similarly formed but 

 more slender, joints 3-6 nearly equal, seventh distinctly larger than 

 the preceding one ; club large, oblong-oval. Eyes not convex. Pro- 

 thorax twice as broad as long, feebly bisinuate at base, sides 

 rounded, as are also the anterior angles, very obtusely and slightly 

 produced in front ; moderately coarsely and closely punctated, with 

 a smooth dorsal elevation. Scutellum invisible. Elytra quadrate, 

 a little broader than thorax at base, moderately convex, abruptly 

 declivous and obtusely rounded behind ; coarsely striate-punctate, 

 the punctures large and square, each elytron ■ appearing as if sex- 

 punctate-striate. Legs squamose : anterior femora grooved below, 

 with a small tooth on the front edge of the groove only, near the 

 apex ; tibicB a little bent, uncinate, setose. Pectoral canal deep, 

 extending into the mesosternum for about half its leiigth. Underside 

 rufescent, coarsely punctate, covered with reddish scales. Basal 

 segment of abdomen largest, third and fourth conjointly shorter than 

 second. 



The insect bears some resemblance to T. ferrugatus, but the 

 form of the thorax is essentially different, the middle part of its apex 

 being scarcely produced, whilst the extremity of the wing-cases is 

 simply rounded without forming a protuberant lobe. The form may 

 be said to be oblong-quadrate, but interrupted medially. 

 Length, 2 lines; breadth, i^. 



I have one individual only, found on Tiritiri Island by Mr. P. 

 Stewart- Sandager.

1546. A. Setifer, "-5. Sub-ovate, convex, not uneven, piceous^ 

 antennae and tarsi yellowish-red, setose.
