Allaorus, though belonging to the same section as these five genera, may be separated by the almost contiguous anterior coxae, abbreviated metasternum, well-developed basal ventral segment, minute eyes and claws, simple 3rd tarsal joint, minute or obsolete scutellum, oviform thorax, and convex body. In the New Zealand list it should be placed near Pselactus, which, however, has the metasternum considerably longer. Allaorus urquharti, Broun. 2577. Man. N.Z. Coleopt., p. 1495. (Plate XVI, fig. 9.) Shining, brownish piceo-rufous, tarsi testaceous, antennae 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 punctured, 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-pieous, metasternum and basal segment with distinct distant punctures, 2nd with very few minute ones, 5th finely and more closely punctate except at the nearly smooth base. The setae slender, scanty, and yellowish. Length, 1 ¼ lines; breadth, ⅜ line. Mount 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 insertion. Thorax shorter than that of 2577, widest before the middle, more coarsely punctured. Scutellum obsolete. Elytra widest in line with the posterior femora, with coarser punctures than 2577, and more deeply punctate-striate behind. Penultimate tarsal joint more expanded and concave. Length, 1 1/10 lines; breadth, ⅜ 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, evidently more narrowed in front than behind, coarsely and rugosely and more closely punctured than the preceding species. Scutellum absent. Prosternum truncate and ciliate in front. Metasternum nearly smooth. Basal 2 segments, combined, with 3 transverse series of punctures. Mesosternum quite smooth. Length, 1 1/10 lines; breadth, ⅜ 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 line; breadth, ⅜ line Mount Pirougia. One
