Hutton. — On a Neiv Species of Wcta. 175 



volcanic rocks not more than 100ft. high, and some four 

 hundred miles south-east from Banks Peninsula. 



The specimen presented to the Museum is a male, and 

 between ljin. and l^in. in length. It is very distinct from 

 any wetas I have seen from New Zealand, and probably, 

 therefore, the species has existed for a long time on those 

 barren rocks, over which the sea-spray constantly flies. I 

 place it temporarily in Ceuthophilus, but it differs from that 

 genus in the shape of the eyes, in the maxillary palpi, and in 

 having a low tubercle on the sternum. However, until the 

 New Zealand wetas are better known, it will, perhaps, be as 

 well not to make a new genus for its reception ; and my only 

 reason for giving a description of it is the interest attached to 

 its habitat. The description of the female is from a specimen 

 in the Otago University Museum. 



Ceuthophilus (?) isolatus, sp. nov. 



Male. — Head moderate, not broader than the prothorax ; 

 smooth, faintly transversely striated on the epicranium just 

 above the clypeus. Antenna short, about one and a half 

 times the length of the body, slender, closely approximated 

 at the base but not touching ; the first joint rather flattened, 

 slightly longer than broa.d, and gently curved with the con- 

 vexity inwards ; second joint shorter than the first, nearly as 

 broad as long, slightly inflated in the middle ; third joint 

 longer than the first, twice as long as the second, slightly 

 inflated towards the base ; fourth and following joints much 

 shorter, about equal, as long as broad, getting smaller towards 

 the distal end, where they are irregular, and many are longer 

 than broad. Eyes sub-semicircular, touching the rim of the 

 cavity for the articulation of the antennae. Ocelli none. 

 Frontal keel reduced to a prominent double spine, the base of 

 which does not extend between the bases of the antennae. 

 Lahrum moderate. Mandibles small. Maxillary palpi mode- 

 rate in length ; the relative length of the joints is 5, 3, 4, 2, 1 — 

 the fifth about as long as the second and third together; the 

 third rather longer than the fourth ; the second twice as long 

 as the first ; the fifth slightly clubbed and abruptly truncated 

 at the end, but not slit longitudinally ; the others cylindrical. 

 Labial palpi short, the third joint longer than the second, 

 clavate and abruptly truncated at the end. 



Thorax smooth ; sides of the thoracic nota broad, conceal- 

 ing the epimera. Pronotum broadest behind, where its breadth 

 is about equal to its length, the sides not projecting below 

 those of the mesonotum, their lateral margins thickened ; 

 lateral furrows obsolete. Meso- and meta-nota much shorter, 

 the lateral margins of the mesonotum thickened, but not 

 those of the metanotum. Metasternum with a short conical
