separated from each other on the forehead by a space only about 

 one-third of the width of the rostrum, and its open scrobes which 

 cut the upper surface of the rostrum sufficiently to be both 

 visible when viewed from above. This form of scrobes is an 

 approach to their form in the Arceocerides, in which, however, 

 both scrobes are entirely visible when viewed from above, and the 

 interval between them is less than the interval between the 

 eyes, whereas in this genus (and others with the scrobes visible 

 and lateral) the interval between them is greater than that 

 between the eyes and only a small part of both scrobes can be 

 seen together. 



N. reticulata, sp. nov. Piceo-rufa, pube albida variegata ; hac 

 in rostro vage, in capite medio longitudinaliter (et cirea 

 oculos) lineatim, in prothorace vage, in scutello confertim, 

 in elytris reticulatim et maculatim, in pygidio ita ut annulos 

 2 format, in sternis abdominis Jateribus pedibusque (in his 

 interrupte) sat dense, disposita ; antennarum clava et 

 pedum nonnullis partibus obscuris ; corpore toto (pube haud 

 abrasa) confertim subtilissime subaspere punctulato : pro- 

 thorace fortiter transverso, antice minus fortiter angustato, 

 lateribus parum arcuatis ; elytris indistincte (latera versus 

 magis perspicue) striatis, striis vix perspicue punctulatis.

On this pretty little species fine dense red-brown very short 

 pubescence covers the upper surface so closely that there is little 

 apparent sculpture ; but, no doubt, if the pubescence were re- 

 moved underlying sculpture would appear. On the red-brown 

 derm-pubescence there is variegation formed by longer pubescence 

 of ashy-white colour. This longer pubescence is vaguely scattered 

 over the rostrum and pronotum and densely clothes the small 

 scutellum; on the head it forms fine lines and on the elytra it 

 runs in fine sinous longit udinal lines, which are here and there 

 transversely connected, — some of the transverse connections 

 (especially between the third and fourth longitudinal lines) being 

 dilated into conspicuous blotches. The derm-pubescence is more 

 red than brown on the head and becomes gradually less red and 

 more brown hind ward. The inequalities of the elytral surface 

 (which are likely to be a generic character) are feebly defined, 

 and best observed by looking at the insect from the side when 

 there is seen to be feeble gibbosity near the base with irregular 

 depression behind the gibbosity, then a scarcely elevated longi- 

 tudinal ridge on the third interstice slightly behind its middle and 

 a still slighter elevation a little nearer the base on the subsutural 

 interstice while between the ridge on the third interstice and the 

 lateral margin the surface is scarcely visibly depressed.
