COLEOPTERA 



as the posterior : tibia flexuose, the posterior most so. Antenna 

 normal. 



Resembles 0. picigularis in form, the clothing, not altogether 

 owing to the contrast in coloration, more obvious, the snout pro- 

 portionally shorter, and the thorax longer and less evidently con- 

 stricted in front. 



Length (rost. inch), if lines ; breadth, -J-. 



One broken specimen, collected by Mr. S. W. Fulton on Mount 

 Maungatua. 



Stephanorhynchus (p. 462). 



*543- S. griseipictus, n.s. Variegate, derm black, covered 

 with fine elongate scales, some white, others yellowish-grey or pale- 

 brown ; antennae and tarsi infuscate. 



Eostrum as long as head, stout ; head ovate-oblong, constricted 

 behind, vertex convex, punctate, neck transversely wrinkled ; eyes 

 prominent, not very large, rather far apart. Antenna slender, of the 

 orthodox pattern. Prothorax conical, considerably narrowed and 

 constricted in front, quite as long as broad, punctate. Scutellum 

 yellowish. Elytra sub-oblong, greatly exceeding the thorax in 

 width and length, humeral angles slightly but obtusely prominent, 

 apices rounded singly, leaving a sutural notch between them ; each 

 with a very large, compressed tubercle near the suture behind the 

 middle, an elongate but not much elevated one at the base, two 

 others near the side, and three or four ill-defined costae. Legs long, 

 two front pairs of thighs simple, the posterior very strongly angulated, 

 dentate below ; all the tibia arcuated, the hind pair most strongly. 



Its nearest ally is S. lawsoni ; this species, however, is decidedly 

 broader, the eyes are smaller and more remote. In both species the 

 head and beak are simple. The name Stephanorhynchus ought, in 

 my opinion, to be restricted to S. curvipes, S. brevipennis, and S. 

 tuber osus at present. S. lawsoni and the present are congeneric ; 

 S. crassus and S. fatuus may ultimately form an intermediate genus ; 

 but, as Dr. Sharp referred his S. lawsoni to this genus, probably 

 with the concurrence of Mr. Pascoe, our greatest authority on the 

 Ehyncophora, I also have used the name for my species.

Mr. T. Chalmer forwarded a specimen he discovered in the 

 neighbourhood of Dunedin.

Psepholax (p. 478). 



1544. P. mystacillUS, n.s. Oviform, convex, clothed chiefly 

 with elongate, depressed grey scales, a little shining, piceous; 

 antennae and tarsi rufescent. 



Eostrum rather long, nearly smooth, having only a few fine 

 punctures, its sides (in front) fringed with fulvous hairs ; head 

 coarsely punctate. Prothorax transverse, contracted anteriorly, 

 base bisinuate, apex incurved, moderately coarsely punctured, the 

 squamosity chiefly confined to a broad longitudinal space near each 

 side. Scutellum small. Elytra with six dorsal striae (on each)
