 Woodhill (Kaipara Bail way). 



Group HISTERIDJE. 



Epierus (p. 163). 



1588. E. abrOgatUS, n.s. Sub-rotundate, convex ; shining, 

 rufo-piceous, legs and antennas dark-red. 



Head distinctly punctured. Prothorax transverse, narrowed 

 anteriorly, base oblique towards each side, indistinctly marginated ; 

 its sculpture like that of the head but rather closer and coarser at 

 the middle of the base. Elytra punctated, each elytron with seven 

 more or less evident, curved striae, all becoming obsolete posteriorly, 

 the sutural not reaching the base, the outermost abbreviated, visible 

 at the middle only. Pygidium finely punctured, quite imperceptibly 

 at the base. Tibia curved externally and expanded towards the 

 extremity, the two front pairs closely denticulated, the posterior 

 with fewer and more minute denticles. Under-surface sculptured 

 like the upper, but much more finely on the middle of the 

 metasternum. 



Allied to E. sy'lvanus, but with distinctly punctured wing-cases. 

 No. 297 is an Epierus.

I found two at Helensville (Kaipara), on logs. 



1589. E. planiceps, n.s. Convex, sub-rotundate ; shining, 

 rufo-piceous, legs dark-red, antennae and tarsi fulvescent. 



Head broadly but slightly concave, not perceptibly punctured. 

 Prothorax almost impunctate, but with one or two rows of punc- 

 tures along the base. Elytra impunctate, each with six dorsal striae, 

 the sutural straight and finest, all obliterated behind. Pygidium 

 smooth. Tibia expanded apically, the anterior arcuated externally, 

 all more or less minutely denticulated. 



Resembles E. abrogatus in form.

My specimen was taken off a log on the Waitakerei Range. 



I59- E. CrenulatUS, n.s. Oblong-oval, convex ; shining, rufo- 

 piceous, legs rufescent, tarsi and antennae fulvescent. 



Head not distinctly punctured. Prothorax transverse, finely 

 marginated, very finely punctated, most evidently near the base. 

 Elytra obsoletely punctured, each with five fine arcuated striae, the 

 fifth marginal, the sutural very indistinct. Pygidium almost im- 

 punctate. Tibia widened towards the extremity, anterior curved 

 externally, all more or less minutely and sparsely denticulated. 

 Underside smooth ; hind margin of mesosternum finely crenu- 

 lated. 



Most nearly resembles E. purus, but in that species the hind- 

 body is more attenuated posteriorly.

I found eight examples at Wcodhill and on the Waitakerei 

 Bange.
