still shorter, very slightly curved, thicker, more pallid setae, which represent 

 the squamosity that is so remarkable in the other^ species. The elytra are 

 rather deeply striate, and the stria? have very large punctures, separated 

 only by short intervals one from the other.

Group Cerai'BYCid.^. 

 Zorion opacum. 



Fusco-testaceum, supra submetallico-nitens, sericeo-subopacum ; antennis 

 pedibusque testaceis, his femoribus basi excepta rufo-obscuris, illis fusco- 

 annulatis ; elytro singulo ante medium fascia pallida transversa marginem 

 lateralem fere attingente. 



Long., 4-5 mm. 



This comes very near to Z. minutum, but is distinguished by the peculiar 

 pallid suffused colour and the silky dullness of the surface. The thorax, 

 instead of being polished, is dull, and covered with a slight sculpture, a 

 sort of minute wrinkling of the surface. The elytra are rather longer than 

 in the other species. 



Chatham Islands ; Professor Schauiusland. Three specimens. 



The British Museum collection includes a specimen of this species said 

 to be from Otago. This locality I think very doubtful. 



Group Lamiid.^. 

 Xylotoles schauinslandi. 



Fusco-rufus, supra viridescens, nitidus, antennis pedibusque rufis ; 

 elytris tricostatis, costis at apicem fere dualis, interstitiis irregulariter 

 interruptim costatis. 



Long.. 10 mm. 



This species comes very naturally between X. traversi and A', costatus. 

 It is not half the size of the latter ; but is a little longer than X. traversi, 

 more elongate, with the sculpture more developed, and the costation con- 

 tinued near to the tip. Of the forms found on the mainland, it is perhaps 

 nearest to X. rugicoUls, but it is very different in colour, and the elytra are 

 singly rounded at the tip. The thorax is elongate and subcylindric, and 

 bears 2 transverse channels ; otherwise it is very indistinctly sculptured. 

 The seutellum is covered with pallid pubescence. The elytra have each 

 an elevated rib running along the suture, and outside this 3 others, the 

 space between bearing much coarse irregular sculpture ; the 3rd costa is 

 itself divided behind the shoulder so as to fork somewhat, and form, in fact, 

 2 costee. The ventral segments hav-e each a conspicuous spot of yellow 

 pubescence at the side. 



The four specimens found by Professor Schauiusland differ but little, 

 and the British Museum collection has two others.

Xylotoles abnormalis. 



Minutus, brevis, testaceus, pnllidus, tomentosus ; thorace fortiter trans- 

 versus ; corporis latera longitudinaliter fuscuscente. 



Long., 5 mm. 



This minute Lamiid looks like a Ilyholasius. but as it is flightless I place 

 it in Xylotoles, where it will come near to A'. hiiUoni. The front of the head 

 is very low, and the moutli much inflexed. The antenna:^ have the 3rd
