468 COLEOPTERA 



oviform. Rostrum rather slender, elongate, somewhat deflexed and 

 arcuated, proceeding from the lower part of the head ; its basal half is 

 narrow and cylindrical, a little incrassated near the eyes, the apical half 

 is abruptly (but not greatly) dilated ; mandibles prominent ; it is of a 

 shining rufous colour, and quite nude. Head punctate, nearly as broad 

 as the thorax, short, deflexed in front ; eyes moderately large and pro- 

 minent, nearly circular. Thorax oviform, longer than broad, the sides 

 regularly rounded, base sub-truncate, disc finely punctured. Elytra 

 oblong, wider than the thorax, somewhat emarginated at the base, 

 shoulders obtuse, the sides nearly parallel and rounded apically ; the 

 disc, owing to slight basal and posterior elevations, exhibits a sub- 

 depressed aspect ; they are punctate but not perceptibly striated. The 

 legs are moderately long, the femora inflated, tibiae straight, not spined ; 

 tarsi stout, basal joint obconical, more slender but rather longer than 

 the second, which is triangular, the penultimate is bilobed, the apical 

 elongate. Scutellum small, somewhat transverse. The body is clothed 

 with sub-depressed stiff fulvous hairs, the legs and antennte nearly nude. 

 Tlie fifth joint of the antenim is obconical and stouter than the others.

I have used R/ihnvnaccr as the generic name of this pretty little 

 beetle ; it does not, however, strictly speaking, belong to that genus, 

 nor to Ji/iyiichitcs, the form of the body is similar to that of Rhinomacer 

 attclaboides, the only European species of the genus, but the structure 

 of the rostrum and antenna? is quite different, so that, most likely, I 

 shall have to make a new genus for its reception. I found one mutilated 

 specimen at Tairua. 



Group— BELID^. 



Under-mentum furnished with a rather long peduncle. Mandibles 

 short, pincer-like, dentate. Head more or less, in general moderately, 

 prolonged behind the eyes ; ivstriim arched, cylindrical ; scrobes sub- 

 medial or basal, very short. Antenncp. straight, gradually thickened 

 towards the extremity but without a well-defined club. Eyes more or 

 less large, prominent. Prothorax without ocular lobes, bisinuated at its 

 base. A sciitclliun. Elytra moderately embracing the body ; their 

 epipleurre sometimes absent. Anterior coxcc cylindrical, prominent ; 

 posterior femora much shorter than tlie abdomen ; tibue unarmed at 

 the apex, their corbels small, terminal, open ; claws free. The three 

 intermediate segments of the abdomen almost equal or decreasing gradu- 

 ally, separated from the first by a straight suture ; projecting intercoxal 

 process small and acutely triangular. Metasternum elongate ; its epis- 

 terna wide. Mesolhoracic epimera rather large. Body winged. 



Pachyura. 



Antenna- longer than head and thorax, inserted near the base of the 

 rostrum, eleven-jointed, gradually thickened and flattened towards the 

 extremity; basal joint moderately stout, about as long as the third;
