I have seen a large number of specimens from Auckland. 

 Amongst them are several varieties, in one of which the white 

 elytral fascia is reduced to a round spot margined with violet, 

 and the pale bases of the femora are terminated by a dusky 

 ring.

Port Nicholson. 



A specimen from Mr. Lawson, taken near Auckland, differs 

 from "Westwood's description by having the head and greater 

 part of the thorax testaceous yellow, nearly as in Z. minutum ; 

 the tibise and tarsi are also violet-broAvn, like the clubs of the 

 femora. It remains with New-Zealand coleopterists to decide 

 by observation on the spot whether these diversities of color- 

 ation really indicate specific differences, and whether there 

 are really more than one variable species in the islands. 



Gastrosarus, nov. gen. 



Corpus lineare, nitidum, sparsim crecte pubescens. Caput exsertum, 

 post oculos paulo angustatuin sed haud elongatnm ; frons brevis, 

 verticalis. Oculi magni, modice convexi et granulati, laterales, 

 supra distantes. Palpi paulo elongati, articulis terminalibus vix 

 dilatatis oblique truncatis. Antennce basi distantes, haud ciliatse ;

 usque undecimum paulo longioribus. Thorax rhouiboideus, la3vis. 

 Elytra linearia, utrinque postice leviter attenuata, apiee acute 

 truncata, supra fere laevia. Prosternum inter coxas augusturn ; 

 mesosternum oblongum ; metasterni episterna fere parallela, 

 apicem versus tantum angustata ; aeetabula antiea et intermedia

 ticorum articido primo vix secundo tertioque conjunctim lon-

Another anomalous genus, having no near affinity with any 

 other known form ; it seems, however, to come nearest such 

 genera as Callimus, and especially the Australian Earinis. 

 I know only the female, which differs from the same sex in 

 Earinis in the concentration of the hairiness of the abdomen 

 on the fifth ventral segment and on the arched borders of the 

 pygidium. The form of the metathoracic episterna is very
