 basal segments are as usual, the next five segments flattened and 

 expanded on the inner side, the ninth flattened but rounded. 

 Prothorax as is normal in the genus ; upper surface smooth and 

 with fine punctures, which can be seen only under a high power 

 and in a suitable light. Scutellmn of the form usual in the genus.

Head : vertex somewhat convex, the rest of its surface as in 

 iV. puikaia. Antennae comparatively longer than in N. birmanica, 

 passing to a certain extent beyond the base of the pronotum ; the 

 three basal segments rounded in section, the first being long and 

 club-shaped ; fourth to eighth flattened, successively increasing 

 in size, not so much produced inwardly as in iV. patkaia ; last 

 segment flattened, but not produced inwardly at all. Prothorax 

 shaped as described under the genus, the punctuation of its upper 

 surface almost invisible unless seen in a suitable light. Scutellum 

 sharply triangular, with the surface impunctate. Elytra almost 

 as broad at the base as the prothorax ; lateral margins somewhat 

 explanate ; surface confusedly punctate with punctures of two 

 sizes, some much finer and others larger, but the punctuation is 

 sparser and less strong than in A 7 , birmanica. Underside closely 

 covered with hair.
