OF NEW ZEALAND. 243 



inwardly ; eleventh larger than tenth, obliquely rounded inwardly ; the 

 form of the club therefore is not at all oviform. 



Femora robust, gradually narrowed towards the extremity; tibia 

 short, compressed, much widened towards the apex, so that their form 

 is elongate-triangular, they are armed along the outer edge with short 

 teeth rather than spines, and are terminated by short spurs ; the tarsi 

 are very short, not much exceeding in length the width of the apex of 

 the tibia, the front ones only are, in repose, received into the tibial 

 impression. 



Length, 2 lines ; breadth, i J. 



I detected my only specimen on the under-side of a log at Tairua. 

 The insect might very well form the type of a second genus of this sub- 

 family. 



Group BYRRHIDJE. 



Head retracted within the prothorax when in repose. Mentum 

 small. Epistome not separated from the forehead. Labrum distinct. 

 Antennas, eleven-jointed, inserted at the sides of the head, uncovered.

Parts of the mouth, the labrum excepted, hidden during the retrac- 

 tion of the head, the eyes also concealed. Ligula divided into two 

 rounded lobes by a slight emargination, membraneous externally, coria- 

 ceous in the middle. Last joint of the labial palpi slightly securiform ; 

 that of the maxillary cylindrical. Mandibles bi- or tri-dentate at their 

 extremity without inner tooth at their base. Labrum rather large, trans- 

 versal, slightly ridged at its base. Antennae with a rather stout basal 

 joint ; second to fourth sub-cylindrical, the third larger than either of the 

 other two ; fifth obconical ; joints six to ten transversal, widening 

 gradually ; eleventh rounded. Legs received in the excavations, tibia 

 rather wide, obtusely angular outwardly at the middle ; all the tarsi 

 retractile, rather short, ciliated underneath, with a membraneous squa- 

 mule below on the third joint.
