OF NEW ZEALAND. 2OI 



I propose this generic name for two species which have extremely 

 the appearance of Tarphius, but differ therefrom by the three-jointed 

 antennal club, and the more elongate basal joint of the tarsi. 



I have little doubt that these insects have the habits of Tarphius, 

 and will require to be sought among the dead leaves and decaying 

 vegetable matter of the New Zealand woods and forests. 



The two species before me, though they look extremely like one 

 another at first sight, show on examination structural differences that 

 leave me no doubt that numerous other species will be found in New 

 Zealand. Enarsus bakewellii, Pascoe, is a very interesting allied form ; 

 but its appearance indicates very different habits, its tarsi have the 

 second and third joints much more developed, and I believe the trophi 

 will show important differences.

 oblongo-ovalis, convexus, piceus, antennis pedibusque ruffs ; setis elonga- 

 tis, erectis adspersus, et cum pube depressa insequaliter vestitus ; tibiis 

 setosis. 



Long, corp., 4^ mm. 



Antenna; short, red, with the basal joints pitchy ; first joint elongate 

 and exposed; third longer, but much more slender than second; fourth 

 a good deal shorter than third, but longer than fifth ; eighth small, but 

 transverse ; ninth and tenth abruptly broader ; ninth not quite so broad 

 as tenth, both of them strongly transverse ; eleventh joint large, about 

 as broad as tenth. Labrum large and exposed ; last joint of maxillary 

 palpi elongate and rather slender. Antennal cavities directed straight 

 backwards along the inner margin of the eye. Eyes large, convex, 

 without setae. Head coarsely sculptured, so as to appear covered with 

 flattened tubercles. Thorax with the sides a little rounded and 

 narrowed towards the front ; the anterior angles acute and prominent ; 

 the sides behind the middle almost straight, so that the well-marked 

 hind angles are about rectangular ; the base on each side much sinuate ; 

 its surface is covered with an exudation which conceals the irregularly 

 distributed tubercular sculpture ; and it bears some erect setae. Elytra 

 very convex, without tubercles, sprinkled with numerous long upright 

 setae, and also bearing some fine, greyish, depressed setae, which are 

 distributed in irregular patches; the sculpture (which apparently consists 

 of rows of coarse punctures) is concealed by an exudation. Tibicz 

 bearing externally a row of long setae. Tarsi with the basal joint about 

 as long as the two following ones together ; the second and the third 

 are small ; the fourth is slender, and rather longer than the other three 

 together. 



A single mutilated individual sent by Mr. Lawson from Auckland. 



NOTE. I found a specimen at Tairua, measuring 2^ lines in length. 



360. S. politus, n.s. Ovate, convex, hispid, castaneous, some- 

 what polished. Antenna short, red ; first joint long and stout ; second 

 short, cylindric ; third long and slender ; fourth to eighth nearly equal 

 to one another; club well-defined. Head granulate; labrum red, more
