ECTOBIUS MAORI, new species. 



Ty^f.— Male; New Zealand. (Koebele.) [Cat. No. (55)43, U.S.N.M.] 

 Allied to E. tasinanicus Brancsik '' and E. marcidus E^richson*' from 

 Tasmania. From tas)nanicus it differs in the general larger size, and 

 in the very nmcli larger pronotum, which also bears a different disk 

 pattern. From niarcidus it differs in the smaller size, and the lighter 

 abdomen. The description of the latter species is very imperfect. 



Size small; form elongate elliptical; surface moderately polished. 

 Head projecting beyond the })ronotum; the interspace between the 

 eyes about twice that between the ocelli; eyes subreniform; antennie 

 not quite equaling the body in length. Pronotum transverse, the 

 greatest width posterior; anterior margin subtruncate; posterior 

 margin Ijroadly ai'cuate; lateral margins arcuate, the anterior angles 

 not at all apparent, the posterior angles obtuseh' rounded; lateral 

 portions rather abruptly depressed. Tegmina reaching to the tip of 

 the abdomen, lanceolate, apex rather blunt; basal field rather broad, 

 short, but slightly exceeding one-fourth the tegmina in length, sub- 

 coriaceous; discoidal vein extending to the tip of the tegmen, costal 

 branches numerous and rather regular; anal sulcus arcuate, slightly
