though it is widely distributed elsewhere. It is a very general feeder, and 

 among its numerous food-plants may be mentioned tea and cinchona ; it is 

 also a pest to palms under cultivation in England. 



Aspidiotus cydoniae, Com stock. 



The examples received occur sparingly along the midrib and veins of 

 the leaves of the Guava, in company with immature females of a species of 

 Ceroplastes. 



Entebbe, Uganda, 25.xi.10 [C. C. Gowdei/, no. 1274). 



Ischnaspis filiformis, Douglas. (The Black-thread Scale.) 



The very long and narrow puparia of this insect look like little bits of 

 black thread attached to the midrib or veins of the leaf of the food-plant.. 

 It has not hitherto been recorded from Uganda, though it has occurred as a 

 serious pest to coffee elsewhere in Central Africa. 



On palms ; Entebbe, Uganda, 25.xi.10 [C. C. Gowdeij, no. 1287). 



APHIDIDiK. 



CeratapMs latanise, Boisduval. 



This curious plant-louse is known generally to horticulturists as the 

 " Fringed Scale,'' otherwise as the " Horned Aphis." It bears a remarkable 

 resemblance to a Coccid, and is often mistaken as such. The late Professor 

 Westwood also mistook it for a Coccid and named it * Asterolecanium 

 orchidearum ; though Buckton t makes no reference to the fact in his 

 monograph. 



It does not appear to have been hitherto recorded from Africa ; but it is 

 a common pest in this country on plants cultivated under glass, affecting 

 chiefly palms and orchids.
