- 198. Apoxa MoscuaTELiina, L.—The flat, exposed layer of 
1oney limits or prevents the visits of long-tongued insects, while 
he greenish-yellow colour of the flowers must cause them to 
smain unnoticed by most flower-haunting Coleoptera. As in 
ther flowers of a similar colour and displaying their honey in a 
imilar way, the visitors are exclusively or almost exclusively 
iptera and Hymenoptera, which in this case are specially 
tracted by the» musky smell. The honey is secreted by a 
eshy ring surrounding the bases of the stamens. The stamens

e each split into two halves, and their pollen-covered surfaces 
e directed upwards in the terminal flowers, and outwards in the 
eral flowers. Insects crawling over the small inflorescence 
ing their feet and proboscides in contact now with anthers now 
with stigma, and effect cross-fertilisation as in the case of the

_ After my M.S. was finished I found a patch of Adoxa visited rather 
abundantly by small insects one sunny afternoon (April 7, 1872). I caught 
fifty-two examples of the following species. A. Diptera—(a) Muscide : (1) 
Borborus niger, Mgn., 2 specimens ; (b) Mycetophilide : (2) various species
