100 ROBERT NEWSTEAD—OBSERVATIONS ON 
Male puparium (fig. 11, b).—White, semiopaque and glassy. Form not differing 
materially from that of the genus Lecanium. 
On African Bark-tree (/’cus sp.); Uganda Protectorate (C. C. Gowdey). 
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, ] think, rightly placed in 
Ceroplastodes ; though the presence of large paired glands have not hitherto 
been observed in that genus. I have much pleasure 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 (Ff. C. Willeocks); found 
also on the “foliage of Mango trees imported from Ceylon,” Horticultural 
Society’s Garden, Gizeh, Egypt, 30. VIII. 1910 (f C. Willeochs). 
This common mealy bug is practically cosmopolitan, and attacks a large 
number of plants belonging to various Orders. 
Tachardia decorella, Maskell. 
On Anona muricata; Masaka, Uganda, 10. IV. 1909 (C. C. Gowdey), 
This lac-producing Coccid is new to the African fauna, having been hitherto 
recorded only from Australia, India and China. Cockerell has described two 
species from Natal, 7. actinella and 7. albida, so that there are now three African 
representatives of the genus. The amount of lac secreted by 7’. 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. 
Antonina(?) africana, Newstead (sine deser.), 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.

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