 [Received 10th June 1922.] 



Various records of the Buprestid, Sphenoptera gossypii, Cotes, from 

 Western "Africa are reviewed, covering the period of 1904 to 1914. 



In 1908 it was recorded as 5. angolensis. Gory, attacking all American 

 cotton and killing the bushes before flowering ; native cotton though 

 also attacked was apparently more resistant. It has been suggested 

 that in localities where the natives are in the habit of growing annual 

 and biennial cotton, only the former should be encouraged. The 

 plants should be pulled up and burned immediately after the harvest 

 in the annual plantations, and those dying or drying up before the end 

 of the harvest should be burned as soon as possible. As stated by 

 Andrieu, in 1914, the control of this beetle is very difficult, as it lives 

 equally well on other Malvaceous plants, particularly wild species of 

 Hibiscus of the group H. sabdariffa, which are widely distributed in 

 the Nigerian bush. Even if this were not the case, the destruction of 

 the plants by fire immediately after the harvest would not be entirely 

 successful, as some of the larvae pvipate and develop into adults before 

 that time. 



Andrieu suggests the placing of the stumps in screened containers 

 so that the parasites, including the Braconid, Pseudovipio andrieui, 

 may escape, but this is not practicable in the case of native growers.

The results obtained on the thermic coefficient of certain of the vital 

 activities of ants are briefly discussed. Activity is found to occur 

 only between certain limits of temperature ; these are variable accord- 

 ing to the species but constant for each species ; for example, Formica 

 tufa is active only between 46° and 104° F., Lasius niger only between 

 50° and 82°, and Myrmica rubra only between 46° and 82°.
