apart at first, but after a short time the stigma inclines to one 

 side and falls against the hairs of one or another of the filaments, 

 after which the flower withers (Calcutta, 24 to 28-ix-01). Cyano- 

 tis fasciculata, Roem. and Schulte's. opens its flowers at the 

 same hour (Sangli near Miraj, 9-x-02). 



Arenga eaccharifera, Labill., and Caryota urens, Linn., 

 drop to the ground their male flowers in enormous numbers, 

 where after the fall they are very diligently visited by Apis 

 indica and Apis florea for pollen (Calcutta, on many occasions). 

 Barbosa Rodrigues in his Noces des Palmier s (Bruxelles, 1903, 

 p. 21) records how he observed that a bee in Rio de Janeiro 

 visits the fallen male flowers of the palm Oulielma speciosa, 

 as they lie on the ground and flies up into the inflorescences above 

 where are the female flowers, so bringing about fertilisation: 

 but I have not observed the bees to fly up onto the female 

 flowers of these two eastern palms, perhaps from want of op- 



portunities.

on a Monday in Calcutta were still affording pollen to bees on 

 the following Sunday. 



Andropogon Sorghum, Brot., and Pennisetum typhoi- 

 deum, Rich., have been seen to be visited by small bees for 

 pollen in the country near Bellary (26-xi-02). 



Araceae. 



Typhonium trilobatum, Schott, I examined a few years ago 

 in Dacca. The mechanism was found to be exactly as described 

 by Miss Cleghorn in this Journal, X. 1914, pp. 421-424. The 

 following beetles were taken within the lower chamber, and 

 kindly named for me by Mr. F. M. Howlett. 



COLEOPTERA. Scarabeidae. Onthophobus sp. ; Gacobius 

 vulcanus) Cacdbius sp., Aphodius moesius, F. Staphylinidae. 

 2 or 3 spp. Nitidulidae. Carpophilus sp. (Dacca, 6 to 10-v-ll). 

 Four species of beetles, unidentified, were also taken within the 

 chamber near Calcutta (27-v-Ol). 



Amorphophallus campanula tus, Blume, was found to be 

 visited by flies of the genera Calliphora and Sarcophaga, 

 attracted by the foul smell (Calcutta, 22-v04). 



Aloeasia fornicata, Schott, of which the smell was not 

 offensive, had within its lower chamber many small Diptera, 

 which were not being held prisoners (Chuadanga, Lower Bengal, 

 22-viii.07). 



Colocasia antiquorum, Schott. On spathes of this plant 

 many beetles and flies were observed; they congregated about 

 the entrance from the upper to the lower chamber (Haflong, 

 N. Cachar, 29-viii-09). Miss Cleghorn has described in this
