stices, the first costae most conspicuous behind, the second and 

 fourth extend from the base backwards, the third does not attain the 

 base. Legs robust. 



Length (rost. inch), 1-^ Hnes ; breadth, f Hue. 



Waitakerei Eange. 



Group-ERIRHINID-ffl. 

 Dorytomus. 



2156. D. groSSUS, ii.s. Ohlong, subdepressed, moderately- 

 shining, pitchy-black, femora red, antennae obscure-red, tarsi and 

 club fuscous, the last joint of the former and extremity of the latter 

 reddish ; body very sparingly clothed with excessively minute grey 

 hairs. 



Bostritm nearly twice the length of thorax, slender, subparailel, 

 very slightly dilated at antennal insertion, arched, so sculptured as 

 to appear covered with elongate punctate depressions and irregular 

 linear elevations. Anteniuc implanted before the middle ; scai^e 

 elongate, slender, straight, gradually thickened towards the ex- 

 tremity; funiculus shorter than scape, first joint longest, second 

 about as long but more slender, joints third and fourth subquadrate 

 and equal, sixth and seventh transverse ; chib oblong, elongate, 

 narrowed apically, apparently four- jointed, opaque with fine 

 pubescence. Eyes subdepressed. Protliorax feebly bisinuate at 

 base, transverse, its sides nearly straight, being only a little rounded 

 towards the front, where it is strongly and abruptly contracted ; the 

 disc is moderately punctured, but the sculpture becomes more ru- 

 gose and subgranular near the sides. Scutellwn small, transversal. 

 Elytra oblong, but little wider than thorax anywhere ; evidently 

 punctate-striate, interstices slightly convex, finely punctured and a 

 little rugose, the intermediate abbreviated behind but not forming 

 any obvious callosity on the summit of the hind sloj^e. Legs robust, 

 anterior femora inflated and dentate below, the posterior more 

 strongly angulated than the middle pair ; tibia flexuose, bearing yellow 

 pubescence near the extremity, distinctly sculptured ; tarsi short 

 and stout, third joint strongly bilobed, apical joint short. 



Female. Antemice medially inserted, scape very slender ; 

 rostrum almost as long as hind-body (2 lines), slender, parallel, 

 arcuate, its sculpture very mucli finer than that of the other sex ; 

 front thigJis with a minute tooth underneath. 



This is by far the largest New Zealand species, remarkable for 

 its oblong outline and very robust legs. The coloration too is very 

 unusual. 



Length (rost. excl.), 3f ; breadth, 1|- lines. 



Messrs. Cheeseman and Adams brought me a pair from Mount 

 Arthur.
