1494 COLEOPTEEA 



not as long as the terminal one, indistinctly separated. Claics 

 moderately long. Prosterniim elongate, Nvidely and deeply emargi- 

 nate in front. Front coxce prominent, contiguous; middle pair 

 globose, prominent, and only slightly separated ; the posterior 

 moderately separated, also prominent. Front and middle legs 

 rather far apart. Metasternum remarkably short, so that the 

 middle and hind coxae nearly touch. Abdomen long, the two basal 

 segments very large, depressed, the first the larger, the intervening 

 suture sinuous, third and fourth very short. 



Scutellum absent. Eyes obsolete or altogether vv^anting. Only 

 four genera are at all allied to this, but none agree with it struc- 

 turally. These genera are : Amaurorrliinus , pertaining to Europe ; 

 Pseiuloonesoxenus, St. Helena ; Pentatemims, Atlantic islands ; and 

 Ilalorhynchus, Australian. 



2576. I. csecus, lis. Shining, red, legs paler, antennae and 

 tarsi yellowish ; with a few minute setae. 



nostrum smooth, its lower front face apparently shaved off or 

 obtusely truncate. Thorax longer than broad, rather narrow, very 

 slightly wider behind the middle than it is elsewhere, its basal 

 margin depressed ; with rather fine but distinct, moderately-distant 

 punctures, each with a minute seta. Elytra with four discoidal 

 striae on each, each stria with eight or ten punctures, the two sutural 

 grooves broader than the others, the posterior declivity more finely 

 sculptured ; interstices indistinctly punctate, with a few incon- 

 spicuous slender pallid hairs. 



Ahdomen elongate, the two basal segments distantly but distinctly 

 punctured, in each puncture there is a depressed, rather coarse, pale 

 seta, there are none on the fifth segment.

Mount Pirongia. Of this remarkable Cossonid I have seen but 

 one specimen, which was picked out of leaf-mould collected by Mr. 

 A. T. Urquhart. 



Obs. — The longitudinal measurements in this group include the 

 rostrum. 



Allaorus. 



Nov. gen. 

 Body convex, only moderately elongate, subovate, nitid, nearly 

 glabrous. Head short, globose below. Bostrum of moderate length, 

 stout, arched, subparallel, only very shghtly dilated near the 

 antennal insertion. Scrohes deep, oblique, extending to the lower 

 front of the head. Antcnnce, inserted beyond the middle of 

 the rostrum. Scape barely reaching the eye, moderately incras- 

 sate apically. Funiculus 7-articulate ; first joint thick, second 

 slightly longer than third, 3-7 increase in breadth, all short ; club 

 ovate. Thorax longer than broad, a little narrowed towards the 

 front, very slightly constricted there, base truncate. Elytra a little 

 wider at the base than at the thorax, feebly obliquely curved towards 

 the suture, obovate. Legs stout ; femora thick, arched above ; tihicd
