100 ROBERT NEWSTEAD — OBSERVATIONS ON 



Male pxipaj'invi (fig. 11,/'). — White, semiopaque and glassy. Form not clifFering 

 materially from that of the genus Lecanium. 



On African Bark-tree (Ficus sp.) ; Uganda Protectorate (C. C. Goicdey). 



The examples were associated with Lecanium nigrum, Neitner, and being for 

 the most part badly damaged or covered with " soot fungus " were mistaken, in 

 the first instance, for the puparia of the Lecanium. 



This very interesting insect is clearly distinct, and is, 1 think, rightly placed in 

 Ceroplastodes ; though the presence of large paired glands have not hitherto 

 been observed in that genus. I have much pleasvu-e in dedicating the species to 

 Mr. C. C. Gowdey, who has done much to advance our knowledge of the Coccid 

 fauna of Uganda during the last two years ; and we sincerely trust that his 

 researches in future may be rewarded by the discovery of many interesting forms 

 of these and other insects. 



Dactylopius longispinus, Targ. 



On vine; Mehelleh-Moussa, Egypt, August, 1910 {F. C. TVilleocks) ; found 

 also on the " foliage of Mango trees imported from Ceylon," Horticultural 

 Society's Garden, Gizeh, Egypt, 30. VIII. 1910 (F C. Willcochs). 



This common mealy bug is practically cosmopolitan, and attacks a large 

 number of jilants belonging to various Orders. 



Tachardia decorella, Maskell. 



On Annua muricata ; Masaka, Uganda, 10. IV. 1909 {C. C. Goiodci/). 



This lac-producing Coccid is new to the African faima, having been hitherto 

 recorded only from Australia, India and China. Cockerell has described two 

 species from Natal, T. actineUa and T. alhida, so that there are now three African 

 representatives of the genus. The amount of lac secreted by T. decorella is not 

 sufficient to be of any value from a commercial point of view. 



Icerya longisetosa, Newstead. 



On the branches of an undetermined shrub, near the north-western shore of 

 Lake Nyasa, 30 miles south of Karonga, 4. VII. 1910 {S. A. Neave). 



This insect was recently described from material collected by Prof. Vosseler, 

 at Amani, German East Africa, on Acacia sp. 



Aspidoproctus maximus, Sanders. 



On an undetermined tree, at Fort Jameson, North Eastern Rhodesia, June, 

 1910 (-S". A. Neave). 



This is the so-called " Goliath Coccid," and is certainly the giant of its race, 

 well-matured examples measuring as much as 33 mm. in length. It was dis- 

 covered by Dr. Fulleborn in 1907 at Langenburg, German East Africa, and 

 during recent years has become a pest in Rhodesia. 



Lecaniodiaspis africana, sp. n. 



Anton/na{?) africana, Newstead {sine descr.), Quart. Journ. Liverpool Univ. 

 I, 2, pp. 69, 72 (1906) ; Draper, Scale-Insects of Egypt, p. 11 (1907). 



This insect may at least be considered as one of the minor pests of Egypt. 

 All the material which has hitherto passed through my hands were immature 

 females without ovisacs. In my private report to the Director of the Institute
