NOTES AND REVIEWS. 4] 



4, The Tea Tortri.r. — The thii-d number of the second volume 

 of the " Circulars and Agricultural Journal of the Royal Botanic 

 Gardens, Ceylon," issued in January, 1903 (pp. 33-45), contains a 

 full account of this tea pest by Mr. E. E. Green, Government 

 Entomologist. It was originally described by Nietner in 1861 as an 

 enemy of the coffee plant. Nietner named it Capua coffearia. 



Instructions are given for fighting this disease of the tea in all 

 its stages of egg, caterpillar, chrysalis, and moth. The eggs are 

 deposited on the upper side of the mature tea leaves in compact 

 masses of about 250. The eggs are disc-shaped objects, pale yellow, 

 " overlapping each other like the scales of a fish, the whole mass 

 coated with a varnish-like film." 



Mr. Green's article is especially noteworthy on account of the 

 admirable lithographic plate which illustrates it. The drawings 

 show all the points referred to in the text ; they were executed 

 upon the stone by Mr. Green himself and printed at the Surveyor- 

 General's Office. 



5. Mosquitoes in Ceylon. — Among the collateral achievements 

 resulting from the brilliant discoveries of Ross and Grassi, which 

 have established the truth of the Mosquito Theory of Malaria, the 

 Monograph of the Culicidae or Mosquitoes of the British Museum 

 by Mr. F. V. Theobald (London, 1901) occupies a prominent 

 position. This work consists of two volumes of text and one volume 

 of coloured plates. In consideration of its size and importance 

 it was produced in a remarkably short space of time. 



The twenty-fifth Circular of the first series of the Royal Botanic 

 Gardens, Ceylon, issued in December, 1901 (pp. 346-368), and 

 entitled Mosquitoes and Malaria, by Mr. E. E. Green, concludes 

 with a list of twenty species said to occur in Ceylon. Many of 

 these were specially identified by Mr. Theobald during the pre- 

 paration of his Monograph. Others, however, such as Stegomyia 

 'pseudotceniata and Armigeres ventralis {^=A. obturbans) are not 

 recorded from Ceylon in Mr. Theobald's pages. There is thus 

 still room for a revision of the Culicid?e of Ceylon.* 



The dominant genera of Culicidae are CwZea; with upwards of 

 125 species scattered over the world, and Anopheles with 44 

 species. Certain species of Anopheles are the intermediate hosts 



* The classification of the Indian species of Atmjihelea has recently formed the 

 subject of a joint memoir by Drs. J. W. W. Stephens and S. R. Christophers in 

 the seventh series of " Reports to the Malaria Committee of the Royal Society " 

 (London, 1902), illustrated by four plates. This series also contains articles by the 

 same authors on the relation of species of Anopheles to Malarial Endemicity : and 

 a paper by Professor E. Ray Lankester '" On a convenient Terminology for the 

 varioiis Stages of the Malaria Parasite."
