OF NEW ZEALAND. 1203 



on the sides they are irregular, whilst the apical sculpture may be 

 termed striate-punctate. 



Not exactly like any other described species; there are no 

 tubercles on the rostrum ; the thorax is destitute of crests ; but there 

 are four scaly prominences on the summit of the hind part of_the 

 elytra, the lower pair more widely separated than the upper. The 

 scrobes are foveiform, but a squamose furrow, shallow but distinct, 

 extends from the point of antennal insertion to the eye. Penulti- 

 mate tarsal joint deeply excavated above. 



Length (rost. excl.), If lines; breadth, quite f line. 



One found on Mount Egmont, at an elevation of 3,200ft., and 

 a second at Stratford, near the base of that mountain. 



2130. P. COStirostris, n.s. Opaque, fuscous; the antennae, 

 tarsi, and front of rostrum reddish. 



This species somewhat resembles P. astutus. The body is nar- 

 rower, and is clothed with minute as well as scale-like setae; these 

 latter form three raised lines on the thorax, the two lateral ones 

 oblique, and four rounded elevations on the posterior part of the 

 elytra, two above and two just below the top of the declivity, there 

 are also four elongate ones near the base, two of which are on the 

 shoulders. The rostrum is arched, rather coarsely punctate, the 

 apical half nearly nude and feebly bicarinate ; the basal portion 

 rather convex, with a distinct ridge along the middle, a little nar- 

 rower than in front, and without crests. Thorax just about as long 

 as broad, its sides nearly straight, closely and rugosely punctate, 

 the middle of the base depressed. Elytra abruptly declivous behind, 

 scutellar region depressed, with series of quite oblong punctures, 

 about seven or eight in each row, the declivity finely punctate - 

 striate, interstices simple, rather regular. Tarsi short. 



In its natural state it is covered with a mud-like coating which 

 effectually conceals the sculpture and clothing, and, when in that 

 condition, appears somewhat cuneiform. 



Length (rost. excl.), If lines ; breadth, f line.

Erymneus. 



2131. E. ferrugatUS, n.s. Elongate; black, clothed with 

 pale-ferruginous scales, with some longer yellowish ones on the more 

 elevated parts ; tarsi and antennae piceous. 



Rostrum elongate, arched, tricarinate in front, bicarinate 

 behind, apex nude ; with four pallid crests, the anterior pair some- 

 times obsolete. Scape flexuous, more or less squamose, extending 

 almost to middle of eye ; second joint of funiculus as long as first ; 

 club short, ovate. Thorax with a central ridge reaching the middle, 

 two oblique basal ones, separated by a depression, ending where the 

 frontal terminates ; one at each side beginning at the apex half-way 

 between the explanate side and the middle and reaching the hind 

 angle ; the coarse rugose punctation is concealed by sappy matter.
