Discovered by Mr. P. Sandager on Halodroma Islet, one of the 

 Mokohinou group. Mesembryanthemum australe forms, in places, 

 a peat-like layer Sin. to lOin. in thickness, and through this the 

 insect burrows. I have, besides one perfect female, the head and 

 other fragments of a male, the description of which is now added. - 



Male. Head transverse, nearly smooth, with two small lateral 

 angulations behind the eyes ; mandibles as long as head, curved, tri- 

 dentate at apex, each with an oblique tooth just before the middle 

 directed inwards but not meeting its fellow. Size of insect, man- 

 dibles included, about 13 lines. 



2322. L. seniulus, n.s. Convex, ovate - oblong, subopaque, 

 black, legs rufo-piceous, antennae pitchy-red ; sides of thorax and 

 elytra densely fringed with short fulvous setae, the base of the former 

 with long, similarly-coloured hairs, base of elytra somewhat pilose, 

 the surface otherwise almost nude. 



Head short, widely incurved in front, punctuation moderately 

 fine, somewhat coarser and not so close between the eyes ; labrum 

 small, strongly rounded at apex, with a few punctures in front, 

 shining; eyes situated close to thorax. Antenna normal, club with 

 yellow pubescence. Thorax strongly transverse, the sides very 

 regularly curved from the anterior angles to the base, so that the 

 posterior are quite obsolete, the base itself not truly truncate, being 

 feebly rounded ; apex widely but not deeply emarginate, the angles, 

 therefore, not prominent ; lateral margins reflexed, the channels 

 distinct ; it is evenly convex, moderately closely punctured, intervals 

 minutely sculptured. Scutellum broadly rounded and smooth behind. 

 Elytra rather narrower than thorax, margins and lateral channels 

 like those of thorax ; each with four or five very feeble indefinite 

 costae ; the punctures on disc of two kinds, very small and moderate, 

 arranged in some places in longitudinal areas but never very regular, 

 the punctures at the sides much coarser. Front tibia produced out- 

 wardly at extremity, with a large subapical tooth and two smaller 

 ones near the middle ; the others with one small projection below 

 the middle. Underside finely sculptured. 



When compared with the female of L. ithaginis the following 

 differences, besides some others, become apparent : The body more 

 oblong and convex, elytra longer. Labrum not truncate, not coarsely 

 rugose. Mandibles tridentate near extremity, but without erect 

 median tooth. Thorax not in the least angulate laterally behind the 

 middle. Elytra differently sculptured, and destitute of minute setae 

 in the punctures.

Boatman's, near Eeefton. One female, found by Mr. A. T. Cavell 

 at a landslip, Fox's Creek, October, 1889. 



1967. L. rufipes, n.s. (Sharp; Trans. Boy. Dub. Soc., 1886, 

 p. 398.) Piceo-niger, femoribus runs, supra hie inde dense fortiterque 

 punctato, punctis squamigeris, areis inter puncta politis.
