Underside shining, the head and breast pitchy red, abdomen nigro- 

 piceous. Metasternum indistinctly granulate. Terminal ventral segment 

 obliquely narrowed towards the extremity, which is subacuminate, with 

 a single setigerous puncture there at each side of the middle. Ihe front 

 and middle tarsi bear elongate setae along their soles, and a spiniform 

 one at the side of the basal four joints. 



Male. — Prosternal process with numerous setae at the tip. Meta- 

 sternum short, with minute granules and setae in the middle. Basal 

 ventral segment at the base, in the middle, finely sculptured and minutely 

 setose, the terminal one distinctly sinuate near the extremity, angulate 

 at the commencement of the sinuosities, the apex itself obtusely rounded 

 and with a pair of setigerous punctures there.

Katapihipihi Forest, Taranaki. A pair of mutilated specimens were 

 found by Mr. W. W. Smith, whose name has been attached to this 

 species. The discovery of the male is important, as without it I had 

 been unable to determine the genus to which other species belonged. 



Obs. — This and the following species will not, I think, remain per- 

 manently with Allocinopus, as they exhibit certain differences. In both 

 sexes the prosternal process is setigerous. The terminal articulations of 

 the palpi are acute at the extremity instead of being obtuse or subtrun- 

 cate ; the maxillary are finely setose, and the penultimate joint is shorter 

 than the terminal. The rigid setae attached to the mentum are very 

 elongate, so also are the pair at the apex of the ligula. The soles of the 

 male tarsi appear to be without distinct sponge-like vestiture, but my 

 specimen having lost one foot, and as the other is not perfectly free from 

 sappy matter, T. do not feel sure on this point. 



3173. Allocinopus castaneus sp. nov. 



Oblong, moderately shining; head and thorax dark castaneous; 

 antennae, legs, and elytra rufo-castaneous, these last paler along the 

 sides near the apices; labium and mandibles piceo-rufous, palpi ful- 

 vescent . 



In most respects similar to A. svriithi. The tips of the terminal 

 joints of the palpi are more pointed, and the 2nd joint of the maxillary 

 more curvate. The forehead is less evidently striate. The anterior 

 angles of the thorax, owing to the very slight apical incurvature, are 

 less prominent, its lateral margins are thinner, and the basal fossae 

 rather more distinct and elongate. The elytra are somewhat more 

 oviform and less acuminate posteriorly. The seta at each side of thorax 

 is placed before the middle, as in the preceding and following species. 



Underside wholly piceo-rufous. Prosternal setae numerous, but not 

 coarse. Terminal ventral segment widely sinuate towards the extremity, 

 which is broadly rounded, instead of being subacuminate, as in the 

 preceding species, it is similarly bisetose. 



$. Length, 7-7£ mm. ; breadth, 2|-2§mm. 



Maketu, Hunua Range. Both specimens are females, and weie found 

 about twenty years ago, at long intervals, during collecting-tours. 



3179. Allocinopus angustulus sp. nov. 



Castaneo-rufous, shining; the legs, palpi, and basal articulations of 

 antennae fulvescent ; remaining joints of these last darker and opaque; 

 epistome, labrum, and mandibles reddish, these hist, however, are nigres- 

 cent at the extremitv.
