1398 COLEOPTERA 



oblong depressions, which are more conspicuous and punctiform on 

 the lateral regions than on the sutural. 

 Greymouth. Helms. 



NOTE. This species is more like Nos. 1791 and 2331 than 

 P. cribralis. The name " rugifrons " was applied fifteen years ago 

 to No. 87. T.B. 



Group POGONID-ffi. 



Sympiestus. 



2439. S. OCUlator, ^-s- Elongate - oblong, slightly convex ; 

 shining, black, femora piceous, tibiae, labrum, and mandibles rufes- 

 cent, palpi and antennae paler. 



Head, owing to the very prominent eyes, appearing much con- 

 tracted behind, with the usual frontal marks. Thorax one-fourth 

 broader than long, widest before the middle, base and apex sub- 

 truncate ; the sides a little narrowed and sinuate behind, posterior 

 angles rectangular, not projecting ; median groove well marked 

 except near the front margin, basal impressions narrow and 

 elongate. Scutellum short. Elytra oblong, rather wider than the 

 thorax, a little rounded laterally, scarcely at all sinuate apically, the 

 sides strongly marginated except near the apices, the hind line of 

 the basal margin feebly marked and not extending inwards beyond 

 the fourth striae, the grooves at each side very shallow but distinct, 

 the discoidal striae and their punctuation well developed. 



This differs from the previously-described species by the shape of 

 the head, which, including the large convex eyes, is not much 

 narrower than the front of the thorax ; the labrum is deeply 

 emarginate, and, besides the large setigerous puncture near each 

 angle, the middle is transversly impressed and bears some minute 

 punctures and setae. 



$ . Length, 3 lines ; breadth, 1 line. 



Hunua Range. My specimen was found by the well-known 

 American entomologist, Mr. Albert Kobele. 



Obpterus. 



2440. O. puncticeps, n.s. Subovate, moderately convex, 

 shining, fusco-piceous ; the labrum, mandibles, elytral rims, and 

 antennae, reddish ; the suture of the elytra, and the base of the 

 thorax, somewhat rufescent ; legs and palpi fulvous. 



Head rather small, the space near the eyes swollen, this causes 

 the back part to appear constricted, the narrow part, moreover, is 

 limited by a linear impression in line with the back part of the eyes ; 

 the frontal grooves are rather broad but not deep, near each eye are 

 two conspicuous punctures. Antenna with basal two joints glabrous. 

 Thorax f line long, f broad ; rather wider at the middle than it is 

 elsewhere, gradually and nearly equally narrowed towards the base 

 and apex, the latter truncate, the former a little incurved, lateral 

 margins of nearly uniform thickness throughout ; disc convex, dorsal
