pressed, foliaceous lobe, having a tooth extending posteriorly ; this lobe 

 is compressed in centre with a diamond-shaped outline at the posterior 

 edge ; about the middle of the posterior process is a cylindrical upright 

 horn, constricted on sides at middle, the upper part produced anteriorly 

 and receives the foliole of the anterior horn which rests upon it ; behind 

 this horn the posterior process is slightly enlarged towards apex, where 

 it is truncated diagonally downward and backward. Elytra light brown 

 ferruginous, with a white band extending across the middle. Tibiae all 

 all widely dilated. 



Length, 5 mm.; altitude, 3*4 mm.

 6. Bolbonota ( Tubercunota) bispinifera, n. sp. 



$ . Black, covered with auriferous pubescence finely tuberculated. 

 Head longer than wide, sides of face dilated ; ocelli on a line with eyes 

 and near base of prothorax, nearer eyes than each other. Prothorax 

 highly convex anteriorly, behind elevated portion strongly declivous ; at 

 upper edge of declivity is a short, cylindrical spine pointing upward and 

 backward, and between this and apex of posterior process is a larger 

 transverse spine pointing directly upward ; lateral angles produced in 

 tubercles, above which are two little elevated lines on each side, the 

 superior one reaching middle of inferior border of prothorax, diverging 

 posteriorly, the surface between these and median carina smooth. Tegmina 

 with basal portion black, remainder hyaline, veins black. Anterior pair of 

 legs dilated, middle and posterior pairs triquetrous, with strong spines, 

 dark brown.

It is near bituberculata, Stal., and inceqicalis, Fabr., and belongs to 

 the subgenus Tubercunota, Godg., which with its relative may be dis- 

 tinguished by the following table : — 



Posterior process of prothorax behind middle furnished with a high 

 transverse tubercle or spine, more or less compressed antero- 

 posteriorly ; anterior part strongly and gradually elevated up to 



middle.., Subgenus Tubercunota, Godg. 



Posterior process from apex, seen from side, depressed, in front of 

 depressed part dorsum straight or lightly uni- or bi-sinuate 



Subgenus Bolbonota, A. & S.
