Of peculiarly elongate, depressed, sub-i)arallel form. Antenuffi stouL, reddish, 

 with the club more obscure ; in structure like those of Cryptophagus, Ist joint almost 

 globular, 2nd short and stout, 3rd not elongate, but longer than the contiguous 

 joints, 4-8 similar to one another, bead-like, 9th and lOtli transverse, 11th rather large. 

 Head rather closely and coai-sely punctured, the eyes but little prominent. Thoras 

 distinctly longer than broad, nearly straight at the sides, very slightly narrowed 

 behind, tlie side margin in front of the hind angles with a minute acute denticle, 

 and the hind angle itself minutely acute ; the surface is rather coarsely but not 

 densely punctured, so that the interstices between the punctures are shining, it bears 

 a fine and scanty pubescence, is flattened along the disc, and indistinctly bi-impressed. 

 Elytra very elongate, bearing rows of distinct, but not very coarse punctures, the 

 punctures bear a fine hair. Under-surface dark reddish, very finely and scantily 

 pubescent. Legs stout, reddish ; the tibiae short, thickened towards their extremity, 

 and curved ; the tarsi short, the three basal joints short and stout, and very pubes- 

 cent beneath, the 3rd joint deeply emarginate, so that the short and small 4th joint 

 is entirely concealed, and can only be detected on a careful examination ; 5th joint 

 short. 



Sent both from Auckland and Tairua hj Messrs. Lawsou and 

 Broun, but only four or five specimens ; Captain Broun's specimens 

 were among some species forwarded to me as found on Cyatliea 

 dealhata. 



Obs. — This remarkable species is, I have no doubt, correctly 

 placed near Mr. Wollaston's Xenoscelis cleplanatus (Canary Islands). 

 In general structure it is very similar to that species, so that I have 

 given it the same generic name, notwithstanding the difference in the 

 tarsi.

Antennae short and stout, with the basal joint quite exposed, the club consisting 

 of the transverse 9th and 10th joints and the narrower 11th joint. Last joint of 

 maxillary palpi longer than the pi-eceding. Eyes free and prominent. Front 

 coxee contiguous, middle and posterior nearly so. Metasternum elongate. First 

 ventral segment of liind-body considerably longer than the following. Legs rather 

 slender ; the tarsi rather short and moderately stout, their basal joint not elongate. 



Obs. — The insect for which I make this generic name, in its form 

 and sculpture, so much resembles a Bhizophagus, that I omitted it in 

 my paper on the New Zealand Colydiidce, from having placed it on one
