Broun. — Revision of the. Neiv Zealand Cossonidse. 197 



Microtribus huttoni, WoUaston. 937. Man.N.Z.Coleopt.,p. 527. (Plate XVI, 



fig- 3.) 



Nigro-piceous, subnitid. antemipe and tarsi piceo-rufous. 



Rostrum distinctly, moderately finely, but not closely punctured, slightly 

 narrowed behind. Head with a fine interocular impression. Thorax 

 moderately coarsely but not closely punctured, the intervals minutely 

 sculptured ; there is usually a linear nearly smooth space along the middle. 

 Elytra rather finely substriate-punctate, the sutural 2 on each most distinct, 

 the others more or less obsolete, interstices with minute punctures and more 

 or less rugose, the sculpture more indefinite behind. 



Underside shining, the metasternum and basal ventral segment coarsely, 

 2nd segment more finely, punctate. 



Length, 1| lines ; breadth, | line. 



Both Islands. Apparently rare. 



M. pictonensis, Sharp. 2203. Man. N.Z. Coleopt., p. 1250. 



Subcylindric, fusco-piceous. Rostrum short, rather thicker than in 

 937, closely punctate, and dull. Antennae very short and thick, inserted 

 behind the middle, the club small and slender. Thorax closely and strongly 

 punctured, rounded at the sides and much narrowed in front, where it is 

 only very obscurely constricted. Scutellum minute. Elytra with series 

 of coarse punctures at the base, but becoming more obsolete towards the 

 extremity, interstices sparingly seriately punctate. 



Length, 3 mm. 



Picton. 



I have not seen this species, but the presence of the scutellum and the 

 different antennal insertion prove that it is not a true Microtribus. 



Idus, Broun. Man. N.Z. Coleopt., p. 1493. 



Minute, convex, medially contracted, nearly glabrous. 



Rostrum arched, quite as long as the thorax, nearly parallel, moderately 

 stout. Scape strongly flexuous, apex incrassate, inserted distinctly before 

 the middle, moderately elongate. Funiculus 5-articulate, laxly articulated, 

 joints 3-5 almost equal. Club abruptly marked off, ovate, evidently an- 

 nulate. Head deeply immersed, globose. Thorax subcyHndrical, its sides 

 a little rounded, not constricted in front. Elytra subovate, convex, rather 

 short, widest behind the posterior femora, narrowed to about the same 

 breadth as the thorax at the base. 



Femora long and stout, not dilated underneath. Tibiaj rather straight, 

 the anterior oblique at the extremity, on the inside, beyond the middle, 

 distinctly ciliate, not visibly uncinate ; the others with a spinule at each 

 angle. Tarsi narrow and elongate, their penultimate joint equally narrow, 

 simple, the terminal elongate. 



Prosternum elongate, widely emarginate in front, the coxae contiguous. 

 Intermediate coxae slightly, the posterior moderately, separated. Meta- 

 sternum much abbreviated, so that the hind and middle coxse nearly touch 

 each other. Basal 2 abdominal segments depressed and elongate, their 

 suture fine and sinuous, the 1st the larger. 



Scutellum absent. Eyes obsolete. These two important characters 

 would seem to indicate that the position of this genus should be in proximity 

 to the Australian lialorhynchus, and Pentatemnus, from the Canary Islands ; 

 both of these, however, according to their descriptions, are materially dif- 

 ferent, whilst the absence of the tibial hooks, in conjunction with other
