 Ventral surface finely rugose; the last segments infuscate at the sides. 

 Legs slender, pale. All tibiae with two spurs. Tarsi with penultimate

Tyx^e.—^o. 1326, U.S.N.M. 



Three examples, collected on Chatham island by Dr. G. Baur. The 

 species resembles Alloxacis dorsalis Melsheimer, from eastern North 

 America, but both mandibles are simple.

Genus PANTOMORUS Schoenherr. 



The following species agrees in most characters with Pantoniorus as 

 amended by Dr. Sharp,' and may be temporarily listed under that 

 genus. The antennae are moderately slender, scajje slightly passing 

 the eye, second joint of funicle nearl}^ twice as long as first, club sub- 

 fnsiform, acute at apex, llostram flat above, feebly emarginate at 

 apex, as long as the head, with a deep median channel from its middle 

 to the vertex. Mandibles with distinct scar, situated on a conical pro- 

 tuberance. Scrobes terminal, visible from above, very deep; arcuately 

 deflexed at a distance from the eye; the acute ridge limiting them 

 above continued straight to the upper margin of the eye. Thorax 

 transversely globose, strongly constricted at apex, without ocular lobes 

 or fimbriae; base less constricted, bisinuate, much more strongly in the 

 male. Scutellum scarcely visible, vertical. P^lytra with distinct but 

 obtuse humeri, Avidest behind the middle; the base of each separately 

 rounded, feebly in the female, more strongly in the male with the mar- 

 gin reflexed each side of the scutellum; disk very convex with ten 

 entire striae of coarse punctures. Wings partially developed. Mentuin 

 large, concave. Front coxae very large, contiguous. Middle coxae 

 narrowly separated. Epimera of mesothorax moderately large. Meta- 

 sternum short, the episterna in front angulate each side. Intercoxal 

 process of abdomen very broad, the first suture angulate at middle, 

 the second segment longer than third and fourth together. Legs long, 

 especially in the male, the intermediate ones the shortest; femora 

 incrassate at middle; anterior tibiae prolonged, strongly denticulate 

 within, arcuate toward apex, strongly mucronate; intermediate tibiae 

 simple in the female, slightly arcuate and denticulate in the male and
