94 SUBANTARCTIC ISLANDS OF NEW ZEALAND. [Coleoptera. 



tarsal joint, with one apical calcar and another at the notch of the inner edge ; the 

 intermediate a little arcuate, bicalcarate at apex, sparsely setose ; posterior slender 

 and elongate.

One specimen, on cardboard, from Mr. Hudson. 



Though doubts may exist respecting L. ambiguus, there can be none as to the 

 validity of this species, as, independently of its small size, the thorax is differently 

 formed, being more deeply sinuate near the base, with the posterior angles, though 

 rather more obtuse, yet more, though but slightly, prominent. The enlarged 2nd 

 and 3rd joints of the front tarsi are very perceptibly different, both, the 3rd par- 

 ticularly, being unmistakably transverse, whilst those of the intermediate are less 

 triangular and elongate — quite cordiform, in fact. No one seems to have secured 

 a single example of the female of any of the species of this genus. 



Loxomerus cilicollis, Umun. 



Subopnque, fusco-piceous, with a large fusco-testaceous sjjace near the extremity 

 of the elytra, legs pitchy-red, palpi ferruginous, antennae rufescent. 



Head finely and irregularly rugose, with shallow indefinite frontal impressions. 

 Thorax similar to that of L. fossulatus, but the basal fossae are very shallow, usually 

 jierhaps almost indistinct, its hind angles a little more sharply defined. E/f/tm 

 similarly sculptured ; the 3rd and 7th interstices are insulated before the middle 

 and consequently do not reach the base, whilst the 2nd striae end near the apical 

 declivity ; they are decidedly longer and more narrowed towards the base. The 

 front tarsi of the male also differ, their dilated joints being more cordiform and less 

 transverse, like those of the larger L. nmbigtms, whilst the intermediate fihiae are 

 nearly as straight and slender as the posterior. The front of the thorax is finely 

 ciliate in both species.

 Inst., 190L 



Loxomerus huttoni, Broun. 



Body rufo-piceous, slightly nitid, legs pitchy-red, antennae and palpi paler. 

 Head finely rugose, not short. Thorax about as long as broad, widest near the middle, 

 only moderately rounded there ; anterior angles slightly prominent, the basal rect- 

 angular, and, owing to the large deep fossae, appearing as if slightly elevated ; the 

 median dorsal groove is distinct. Scutellum short. Elytra oblong-oval, rather broad, 

 with fine, regular, impunctate striae ; interstices simple. 



Tn this species the eyes are less prominent and more distant from the thoracic 

 margin than in L. cilicollis. The thorax is rather longer, and differs in shape ; its 

 sides are quite obviously marginated, and the basal foveae are large and deeply 

 impressed. The elytra also differ in contour, owing chiefly to being less narrowed 

 towards the shoulders.
