Prof. Schauinsland found three individuals of this species, but 

 o]ie of them has unfortunately lost the head and thorax. 



ClLTBE SUBCOSTATA, Sp. nOC. 



Nigra vel ficea, minuft dcpressa, fortiter sculptuvata, opava, elytris 

 evidenter suhsulcatis. Long. 13| mm. 



This is distinguished from all the other species by the peculiar sculpture of the 

 elytra, which however is only an exaggeration of what we find in some other 

 forms. The front angles of tlie thorax are much produced and the sides are much 

 explanate ; their margins a little sinuate, the hind angles much produced backwards 

 and markedly acute ; tlie punctuation at the sides is very dense, on the disc it is 

 scanty, but the surface is not in the least shining. The elytra are rather short, and 

 have a vague costation, the very slightly elevated ribs are separated by coarser punc- 

 tures ; this sculpture strongly sets off, and makes evident, the ribs. 



Chatham Island. 



Prof. Schauinslaud found a small series of this species. It is 

 nearest allied to C. pascoei, Bates, of Pitts Island, a species which was 

 also met with there by the Grerman traveller. G. pascoei, \% however, 

 rather more elongate and less convex in form, and with the sculpture 

 of the elytra different, there being merely traces of the longitudinal 

 ribs. Prof. 8chauinsland's specimens are intensely black, being 

 considerably darker in colour than Mr. Bates' type. I have dissected 

 the sexes of C. suhcostaio and do not find any external marks to 

 distinguish them. 



CiLIBE TARSALIS, Sp. nOV. 

 Lata, nigerrima, subdepressa, densissime punctata, opaca, pedibus 

 crassioribtis, ta?'sis suhtus densius spongiosis, anticorum articulo primo leviter 

 dilatato. Long. 20 mm., lat. 10 mm. 



I have seen only one specimen of this species. I received it a few years ago 

 from Mr. Suter. It is labelled in the handwriting of Capt. Thos. Broun '• Cilibe 

 opacula," Bates, Albury. Though very similar to that species, it differs in a well- 

 marked manner by the structure of the feet, and though this may be peculiar to the 

 male it is sufficient to differentiate the form from C. opacula. It is a little broader 

 in proportion to the length, the thorax is rather more transverse and less narrowed 

 in front and the head mai'kedly broader. The punctuation is much the same as it 

 is in C. opacula. The tibise are slightly shorter and thicker, and they have only an 

 indistinct external pre-apical angle ; the thickening of the basal joint of the front 

 feet though slight is perfectly definite, and I can find nothing to correspond to it in 

 any other species. 



Albury, New Zealand. 



I have a specimen given to me by the late C. M. Wakefield, who 

 found it in the Peel Forest in March, 1874. It was submitted by me
