OSSORIIDAE. 17 



Tibiae liJiely Hpi)iose externally. Antennae nearly as long as head and 

 thorax ; l)asal joint cylindric. evidently thicker and longer than 2nd ; 3rd 

 rather longer than 2nd. narrowed towards its base ; 4th smallest and head- 

 like : Sth" of similar form, but slightly larger ; 6 10 laxly articulated, 

 broader than preceding ones ; llth conical. 



Prosfernuvi distinctly incurved near each side of the apex, the angles 

 obtusely carinate and prominent, the centre in front of the coxae is also 

 obtusely prominent. Fifth ventral segment unimpressed ; in //. brorini 

 this segment is medially deeply concave, and the basal one cariniform in 

 the middle. 



.Similar to //. hrevipennis in some respects. In it, however, the eyes are 

 obsolete or altogether absent, the base of the thorax is widely emarginated, 

 and the greyish-yellow pubescence, though scanty, is easily seen. 

 ? . Length, 1| lines ; breadth, f line. 



Mount Pirongia. Both specimens found !)>' myself amongst decaying 

 leaves. 

 3040. Holotrochus caecus sp. nov. 



Cylindric, shining, sparingly clothed with slender yellowish-grey hairs : 

 ■dark red, hind-body with indefinite darker spots, antennae and legs reddish. 

 Head smaller than thorax, with a few fine distant punctures. Antennae 

 with fine grey pubescence, basal 3 joints elongate. 3rd slender. .5th and 6th 

 obconical, broader than -Ith, joints 7-10 larger. Thorax quadrate, finely 

 margined laterallv. finely and distantly punctured. Elytra transverse, 

 subtruncate behind, with shallow indistinct sculpture. Hind-body elongate, 

 basal 4 segments simple and equal. 5th large, with coriaceous minute sculp- 

 ture. 



Tibiae stout, the intermediate moderately closely and finely spinose 

 externally ; the anterior with 5 or 6. the posterior with the same number 

 of fine setiform spines near the extremity. 

 The eyes I am unable to detect. 



H. brevipennis is smaller and darker, with differently formed antennae, 

 their 5th joint being oviform and rather larger than the contiguous ones. 

 It is in a similar blind condition. 



Length. If fines ; breadth, quite | line. 

 Maketu. Hunua Range. A single specimen. 



3041. Holotrochus gracilis sp. nov. 



Shining, ferruginous, legs and antennae flavescent, pubescence also 

 yellowish. 



This is another sightless species, which is smaller and more slender than 

 the preceding one, and distinguishable by the paler colour of all its parts. 

 The sculpture seems similar l)ut is even finer, and the suture of the trans- 

 verse elytra is indistinct. 



Length. IJ lines; breadth, l)arely f line. 



Waitakerei Range. Found in March, 1909. Unicjue. 



3042. Holotrochus nitidorsis sp. nov. 



Elongate, subcylindric, glabrous, glossy ; head and thorax rufo-fuscous. 

 the area near the posterior angles of the latter usually paler ; elytra and 

 hind-body fnsco- or rufo-piceous, the apical portion of the basal segmentr; 

 of a more or less metallic reddish-coppery hue ; legs and antennae pitchy- 

 red, tarsi testaceous. 



Head nearly as long as the thorax but obviously narrower, the 

 forehead rounded in front, with a few distinct but not coarse scattered
