Cohoptera from New Zealand. 235 



distinct margins, nearly horizontal ; when seen from the side 

 the middle appears somewhat angulate and depressed. (7/?/- 

 peus inflexed-perpendicidar. Labrum moderately large, its 

 basal suture distinct. Antennal cavities shallow, widely 

 separated. Eyes large. Antennoe elongate and slender, 

 filiform ; basal joint short and stout, second abbreviated. 

 Tarsi elongate, slender, simple ; fourth joint of the posterior 

 more than half the length of the third, the basal joint rather 

 longer than the fifth. 



Chin-piece well developed, much curved, so that an evident 

 gap exists between it and the rather acute anterior angle of 

 the thorax. Prostemal sutures not distinctly duplicate. Pro- 

 sternal process hastate, narrow, of only moderate length, 

 nowhere more than half the wi^th of the space between the 

 coxee; it is on an abruptly lower plane (nearer the breast), 

 and is ridged along the middle. Mesosternal cavity deep and 

 sharply limited, oviform, without margins, hardly extending 

 beyond the front of the middle coxaj ; the space between 

 these latter flattened or impressed. Intercoxal suture well 

 marked. Coxal lamina simple, its trochanteral portion about 

 twice as long as the femoral. 



The type of this genus displays such peculiarities of struc- 

 ture that it cannot be placed in any genus known to me. It 

 should, I think, be placed near Chrosis. 



Zeaglophus pilicorais^ sp. n. 



Elongate., moderately attenuate posteriorly, only slightly 

 convex ; pubescence fine, ash-coloured, not dense ; shining, 

 black ; tibiie and tarsi fuscous. 



Thorax about as long as broad, much narrowed anteriorly, 

 its sides behind the middle gradually but considerably 

 explanate and flattened ; posterior angles rather short, thick, 

 not at all divergent ; the apices, indeed, are almost turned 

 inwardly ; the lateral portions are distinctly punctate, the 

 disk is much more finely and quite distantly. Elytra 

 evidently striate, the outer strias distinctly punctured, the 

 posterior sculpture irregular and ill-defined ; interstices with 

 fine serial punctures, not rugose. 



Underside pitchy black, with depressed greyish pubescence, 

 moderately finely and closely punctured ; the flanks, as well 

 as the middle of the prosternum, however, bear larger and 

 more distant punctures ; the raetasternum is convex. 



Antennce moxQ than half the length of the body, not serrate, 

 with long outstanding, conspicuous, fuscous setae or hairs ; 

 first joint short and stout, rather shorter than the third ;
