The narrow, parallel outline, less Bhining surface, and rather 

 diluted (or rufescent) hue of this elongate Pentarthrum (which is 

 from New Zealand, and has been communicated by Dr. Sharp), in 

 conjunction with the broad and deeply bilobed third joint of its feet 

 and the great sexual dissimilarity in its rostrum (which in the female 

 sex ia long, polished, and acicular, but in the male comparatively broad 

 and sculptured, though gradually and conspicuously rounded inwards, 

 or attenuated, behind the middle), will at once separate it from every 

 other species which has hitherto been described. Its scutellum is 

 large and transverse, its legs are somewhat short and thickened, and 

 its rostrum (as in the ordinary members of the genus) is scarcely at 

 all separated from the forehead by a constriction immediately behind 

 the eyes, — which latter structure forms so remarkable a feature in the 

 P. longirostre, which occurs likewise in New Zealand.* In the slight 

 sexual dissimilarity of its prothorax (no less than in that of its rostrum) 

 it makes a more decided approach than is usual amongst the Pen- 

 tarthra to certain members of the true Gossonides, such as we see in 

 the groups around Mesites. I have had much pleasure in naming the 

 species after Dr. Sharp, who has at various times entrusted to me the 

 most interesting consignments of New Zealand Cossonids — received 

 from Auckland by Mr. E. Lawson, of Scarborough.

Although its scape is less shortened than that of the South African 

 B. crassirostris, and its rostrum is both less thickened and less trian- 

 gular, I, nevertheless, am inclined to suspect that the somewhat

 enables me to coirect the diagnosis of that sjiccics a.s rejjards size, — which, instead of beuig from
