surface of the prouotum is conspicuous : the thorax is, too, much 

 longer. The colour varies somewhat in the same manner as it does 

 in T. exiguus. 



Sab. : New Zealand, Grey mouth (Helms). 



A single specimen from Otago, differs slightly in so many details 

 that it very likely belongs to another species. 



BLEDIOTROGtJS, t/en. n. 



A Trogoplilceo tihiis quatuor anteriorihus externe spinulosis, corporisque 

 sculpturafere ut in genere Bledio discedit. 



The little Troqophloeus -iorm for which I establish this genus 

 makes a decided approach to Bledius. The palpi are formed as in 

 Trogophlceus, and the scutellum is quite concealed. The prosternum 

 and mesosternum form each a sharp angle in front of the coxae : the 

 front coxa? are elongate and vertical. The antennae are not geniculate, 

 but the front and middle tibiae are armed externally with distinct 

 spines. 



Blediotrogus guttigee, sp. n. 



Trogophloeus gxittiger (Fauvel, not described). 



Niger, antennis pedib usque fuscis, elytra singula ad ajyicem macula magna 

 testacea ; prothorace fortiter punctato, medio laevigata; ahdomine dense sub- 

 tilissime puHctato et puhescode, opiuco. Long., 3 mm. 



Antonnre iTifuscate red, paler towards the base ; 3rd joint a good deal longer 

 than the 2nd, but shorter than tlie 4th, 9th and 10th joints broader than the 8th, 

 slightly transverse. Head rather small, the eyes prominent, behind scarcely sepa- 

 rated from the neck ; antennal tubercles strongly prominent ; clypeus and a small 

 space along the middle behind it smooth and sliining, with rather deep punctures 

 on each side. Thorax a good deal narrower than the elytra, not much shorter than 

 broad, considerably narrowed behind, black, along the middle polished, on each side 

 ■with numerous fine, somewhat distinct punctures, each bearing a fine, depressed 

 hair. Elytra much longer than the thorax, shining, finely and not densely punctured, 

 with an extremely fine pubescence, blackish, with a large yellow mark behind, di- 

 vided into two by an angular prolongation of the dark colour along the suture to 

 the tip. Legs infuscate red, the tibiae darker, tarsi pale. Metasternum shining in 

 the middle and biseriately punctate. 



Hah. : New Zealand, Auckland (Latoson). 



I have now only one specimeu of this very distinct and interest- 

 ing little species.
