OF NEW ZEALAND. 1231 



near the apex. Legs slender, the posterior femora strongly angu- 

 lated and produced below, the others simple ; the two hind pairs of 

 tibiae strongly curved. 



Most nearly resembles S. griseipictus but much smaller, without 

 small tubercles on the elytra before the large sutural ones. It has 

 a shorter hind-body than S. laivsoni, and is otherwise different. 



Length (rost. incl.), If lines; breadth, f- line. 



I am indebted to Messrs. T. F. Cheeseman and J. Adams for two 

 examples which they found on the Mount Arthur plateau, about 

 4,000ft. high. 



2169. S. insolitUS, n.s. Elongate, variegate; body fuscous, 

 covered with minute, depressed, greyish scales, and a few coarse, 

 curved, white setae ; legs pale-brown but with the middle of the 

 femora sometimes as dark as the tarsi ; antennas fusco-rufous. 



Rostrum longer than thorax, gradually raised and compressed 

 towards the eyes ; between these latter the head is flat, but it is 

 considerably elevated behind them, the back part is constricted and 

 depressed, and with a well-marked longitudinal channel. Eyes very 

 convex and prominent. Antenna moderately slender, the two basal 

 joints of the funiculus of nearly equal length ; third shorter than 

 second, yet twice as long as broad ; seventh transverse ; club elon- 

 gate, second joint but little larger than the first. Thorax rather 

 short, abruptly and deeply constricted in front ; plain, its sculpture 

 consisting of small punctures and transverse wrinkles. Elytra' 

 broader than thorax at the base, gradually narrowed posteriorly, 

 without tubercles or distinct elevations, the suture convex apically, 

 indistinctly striate-punctate, transversely impressed behind the base, 

 the third interstices slightly elevated near the middle. Legs normal, 

 femora dentate, tibiae curved. 



A very peculiar species, owing to the absence of the usual pair 

 of elytral elevations and other asperities. When viewed sideways it 

 will be noticed that an evident gap or depression exists on the head, 

 somewhat similar to that of S. tuberosus (No. 1268), but even more 

 abruptly defined ; in both species the second joint of the club is much 

 shorter than it is in S. curvipes. 



Length (rost. incl.), 3f ; breadth, 1-J- lines. 



Taken off Aciphyllae by Mr. G. V. Hudson. 



OBS. Since describing S. tuberosus I found some varietal forms 

 on Mount Egmont, one on the Waitakerei Eange, and I have 

 another which was brought from Te Aroha by Mr. A. T. Urquhart. 

 Dr. Sharp's S. aper is another variety of this species. 



2170. S. COStifer, n.s. Fuscous, densely covered with slender, 

 depressed scales, and a few erect setae, yellowish or infuscate-grey in 

 colour; antennae obscure -ferruginous, club infuscate ; the legs 

 covered with pallid and infuscate squamae, tarsi reddish, tipped with 

 fuscous. 



S. insolitus most nearly resembles this species. The head is 

 nearly flat behind the eyes, the back part is broadly contracted.
