Broun. — Revision of (he New Zealand Cossonidiie. 209 



Alhiorus. though belonging to the same section as these five genera, 

 may be separated by the ahiiost contiguous anterior coxa-, abbreviated 

 motasternum, well-developed basal ventral segment, minute eyes and claws, 

 simple 3rd tarsal joint, minute or obsolete scutellum, ovifoi'm thorax, and 

 convex body. In the New Zealand list it should be placed near Pselactus, 

 which, however, has the metasternum considerablv lonoer. 



Allaorus urquharti, Broun. 2577. Man. N.Z. Coleopt., p. 1495. 

 (Plate XVI, fig. 9.) 



Shining, brownish piceo-rufous, tarsi testaceous, antennre ferruginous. 



Head globose, but immersed nearly to eyes. Rostrum with some fine 

 distant punctures. Thorax slightly wider behind the middle than it is 

 elsewhere, rather narrower in front than at the base, without any apical 

 stricture ; very distinctly, moderately coarsely, and rather distantly punc- 

 tured, more finely at the apex. Scutellum very minute. Elytra widest 

 near the middle, much narrowed posteriorly, convex ; each with 4 series of 

 discoidal punctures, about 7 in each row, these hardly extend beyond the 

 disc ; the posterior declivity is striate. The setae are slender and indistinct. 



Underside shining, rufo-piceous, metasternum and basal segment with 

 distinct distant punctures, 2nd with ver}^ few minute ones, 5th finely and 

 more closely punctate except at the nearly smooth base. The setfe slender, 

 scanty, and yellowish. 



Length, l^ lines ; breadth, f line. 



Moimt Pirongia. Four. 



A. pedatus, Broun. 2578. Man. N.Z. Coleopt., p. 1496. 



Shining, fusco-testaceous, apex of thorax and base of elytra darker ; 

 the setae scanty, very slender, and inconspicuous. 



Rostrum very slightly narrower behind than in front of the antennal in- 

 sertion. Thorax shorter than that of 2577, widest before the middle, more 

 coarsely punctured. Scutellum obsolete. Elytra widest in line with the pos- 

 terior femora, with coarser punctures than 2577, and more deeply punctate- 

 stria te behind. Penultimate tarsal joint more expanded and concave. 



Length, ly^n ^i'lPS : breadth, f line. 



Mount Pirongia. Two. 



A. sternalis, Broun. 2579. Man. N.Z. Coleopt., p. 1496. 



Rufo-piceous tinged with fuscous, antennae and tarsi red, club infuscate ; 

 setae inconspicuous. 



Thorax widest at the middle, evident!}^ more narrowed in front than 

 behind, coarsely and riigosely and more closely punctured than the preced- 

 ing species. Scutellum absent. Prosternum truncate and ciliate in front. 

 Metasternum nearly smooth. Basal 2 segments, combined, with 3 trans- 

 verse series of punctures. Mesosternum quite smooth. 



Length, IJ^ lines ; breadth, f line. 



Mount Pirongia. One. 



A. ovatus, Broun. 2580. Man. N.Z. Coleopt., p. 1497. 



Shining, fuscous, slightly tinged with red, antennae rufous ; setae indistinct. 



Thorax shorter than that of 2577, the punctures rather closer and only 

 slightly coarser. Scutellum absent. Punctuation of elytra very irregular 

 and coarse, only 4 or 5 punctures in some rows on the disc. 



Length, 1 Une ; breadth, f line. 



Mount Pirongia. One.
