field-naturalist than the systematist. The synonymy of certain species 

 is discussed at length. 



Owing to the great disagreement upon the fundamental points of 

 a classification, and even the status of genera and subgenera, the author 

 has adopted the group system. The termites dealt with belong to ten 

 groups and twenty-one genera, and include the followdng new species : — 

 Calotermes braunsi from the Cape south coast ; Cryptotermcs mervaei 

 from the Natal coast ; C. pseudobrevis from Durban, localised in the 

 centre of the town, where it infests wood-work ; Hodotermes peringueyi 

 from Albany, etc. ; H. thomseni from the Great Karroo ; H. silvesirii 

 ranging from van Rhynsdorp to the Orange River ; H. faurei 

 from Victoria West ; H. pallidus, for which a new^ subgenus, 

 Macrohodolermes, is erected, from the Cape Province ; and Schedo- 

 rhinoiermes pulorius australis, subsp. n.

 nararia, Moore. — Sine loco, n.d., 6 pp. [Received 5th October 

 1921.] 



This paper contains detailed notes on the life-history of Natada 

 nararia, the caterpillars of which were found defoliating a hedge of 

 Pithecolohium dulce. The eggs are laid singly on both sides of the 

 leaves and hatch in about five days, the larval period lasting thirty-one 

 days and the pupal fourteen. The average life of the adult moths in the 

 laboratory was five days. The larvae are parasitised by an unidentified 

 Braconid.

 A Preliminary Investigation of the " Pollu " Disease of Pepper 

 in North Malabar in 1918. — Sine loco, n.d., 14 pp. [Received 

 5th October 1921.] 



• The bulk of the information contained in this paper on the life- 

 history of Longitarsus nigripennis. Mot., and the relation of this 

 flea-beetle to " pollu " disease of pepper in North Malabar has already 

 been noticed [R. A.E., A, ix, 214]. Further remedial measures include 

 the clipping and destruction of portions of spikes which show distinct 

 attacks. Reduction of shade may also be effective in checking infes- 

 tation, and clean cultivation should be practised. It is difficult to 

 apply sprays uniformly from top to bottom of the vines. Paris 

 green at the ordinary strength injures the foliage, but a spray of Paris 

 green, Bordeaux mixture and lead arsenate was found effective.
