OP NEW ZEALAND. 1847 



Micramhina, a genus, or snb-,genus, whose description I liave been 

 unable to see. 



Salltius. 



Kov. gen. 



Crijjytophagus is a nearly-allied form. The distinguishing cha- 

 racters are as follow : — 



The antennce are more approximated at the point of insertion, 

 they are longer and stouter, two-thirds the length of the body, and 

 differently formed ; basal joint subpyriform, wholly exposed, third 

 slightly longer and more slender than the second, fourth much 

 smaller than the contiguous ones, bead-like, fifth elongate, nearly 

 as long as the first but more slender, joints 6 and 7 longer than 

 broad, the former the shorter, the latter nearly as long as the fifth, 

 eighth small and moniliform ; club laxly articulated, ninth and 

 tenth joints large, obconical, eleventh broadly oval. Eijes more 

 prominent. The taTsi are, seemingly, heteromerous; their penulti- 

 mate joint has elongate lobes. The anterior coxoi are less widely 

 separated. The irrosternum is transversely convex, and its process 

 projects beyond the coxae. The viesosternnm has a triangular 

 acuminate process. The mctastermtm is short ; it is rounded be- 

 tween the middle coxae, but incurved in front of the hind coxge. 



The type is No. 399, now Salltius ruficeps. The first joint of 

 the antennae is dark-red and distinctly sculptured. The body is 

 more convex than it is in Cryptopliagus, and the thorax and elytra 

 are differently formed. 



Group— LATHRIDIID-ffi . 



Diarthrocera. 



Nov. gen. 



Boclji subdepressed, ovate-oblong. Head as broad as the front 

 of the thorax, much narrowed anteriorly. Eyes large, rotundate, 

 distinctly facetted. Autennce inserted at the sides of the head in 

 front of the eyes, biarticulate, basal joint stout, thickened towards 

 the extremity, the second half the size of the first, l^oth with a few 

 fine hairs. Thorax about as long as broad, a good deal narrowed 

 towards the base, its sides rounded, and, apparentlj^ finely denticu- 

 late. Scntelliim transverse. Elytra oblong. Prosternnm simple. 

 Anterior coxa? of moderate size, nearly contiguous ; middle coxae 

 narrowly separated ; the posterior widely distant. Metasternum of 

 moderate length, its frontal process extending halfway between the 

 coxae. Ahclomen composed of six segments, the apical very short, 

 the basal largest:, the mtermediate ones nearly equal to one another. 

 Femora stout, simple. Tihue somewhat arcuate or flexuous, their 

 inner extremity mucronate. Tarsi stout, three-jointed, pubescent 

 underneath, the basal joint much larger than the second and some- 

 what prolonged below, second joint of similar form, third quite as 

 long as the preceding two taken together ; claws distinct.
