1180 COLEOPTEBA 



elevation of the fifth interstice, a Httle more to the front than the 

 other elevation. 



Greymouth. Helms. Mr. Helms identified the sexes of this 

 species for me by observation of the living insects. The male appears 

 to be rather more slender than the female. 



2091. P. robustus, ii.s, (SJiarj) ; Trans. Boy. Dub. Soc, 

 1886, p. 118.) Latior, griseo-squamosiis, antennis pedibusque 

 piceis ; protJiorace rugoso ; clytria ante apicem nodulosis, apicibus 

 productis acuminatis (an feminte tantum?), medio ante apicem 

 pallido-squamoso. 



Long., 8mm. 



This is distinguished from the other species not only by its larger 

 size, but also by the more uneven surface and broader scutellum. 

 The rostrum is carinate along the middle and minutely foveate be- 

 tween the eyes ; the surface of the thorax has numerous coarse 

 rugcB ; the broad elytra also have the surface uneven, and bearing 

 series of rather coarse distant punctures, each of which is occupied 

 by a more pallid scale, the interstices present here and there slight 

 longitudinal elevations, the third, fifth, and seventh have each a 

 more distinct elevation at the commencement of the declivity, that 

 nearest the suture being much the larger ; behind these two larger 

 elevations the surface extending to the apex is densely clothed with 

 more pallid scales, and on either side there is a large patch of darker 

 (nearly black) scales ; the apices are prolonged. 



Otago. Professor Hutton ; one example. This is probably a 

 female, and from analogy with P. cuspidatus it is possible the male 

 may have the apices less produced. The species bears a superficial 

 resemblance to Catoptes, from which the forni of the head and 

 anterior parts of the thorax readily distinguish it. The tips of the 

 posterior tihice. are even less cavernous than they are m P. gracilis ; 

 so that, had it not been for my previous knowledge of that insect, I 

 should have considered the corbels as open in the present insect, 

 yet a really careful inspection shows that they are truly cavernous 

 in a rudimentary manner. The sculpture and form of the insect are 

 very similar to those of Empceotcs coisorins, Pascoe ; but that has a 

 less pterygiate rostrum, with definite scrobes directed towards the 

 front of the eye. 



Tigones. 



52092. T. aulica, n.s. Body shining pitchy-black, legs pale 

 rufo-castaneous, antennae reddish ; densely covered with small, round, 

 grey (tinged with red) scales; setae slender and inconspicuous except 

 those in the elytral puiictures, where they are somewhat squamiform. 



Bostrwii robust, not perceptibly carinate, densely clothed. An- 

 ten)i(E rather thickly clothed v>dth greyish hairs, not seta3 ; second 

 joint of funiculus as long, or almost as long, as the first ; third nearly 

 equalling the preceding one ; joints 4-7 moderate ; club oblong-oval, 

 acuminate, bearing minute brassy setae. Thorax about as long as 

 broad, a little constricted in front, its sides very obtusely rounded;
