OF NEW ZEALAND. 1347 



Micrambina, a genus, or sub-genus, whose description I have been 

 unable to see. 



Salltius. 



Nov. gen. 



Cryptophagus 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. Eyes more 

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

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

 separated. The prosternum is transversely convex, and its process 

 projects beyond the coxae. The mesosternum has a triangular 

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

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



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 Cryptophagus, and the thorax and elytra 

 are differently formed. 



Group-LATHRIDIID M . 



Diarthrocera. 



Nov. gen. 



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

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

 distinctly facetted. Antenna 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, both with a few 

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

 towards the base, its sides rounded, and, apparently, finely denticu- 

 late. Scutelhim transverse. Elytra oblong. Prosternum simple. 

 Anterior coxae 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. Abdomen composed of six segments, the apical very short, 

 the basal largest, the intermediate ones nearly equal to one another. 

 Femora stout, simple. Tibia 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.
