OBSERVATIONS ON SCALE-INSECTS (COCCIDAE) — V. 127 



Pseudococcus hymenocleae, Ckll. 



South Africa : Onderstepoort, Transvaal ; food- plant not stated, 1914 

 (D. d'Emmerez). 



Pseudococcus virgatus, Ckll. 



Uganda : Nama Konkoni, Chagwe ; on coffee (C. C. Gowdey). Zanzibar : 

 on cassava and sugar-cane, 4. iv. 13 (Dr. W. M. Aders). Gold Coast: Aburi, on 

 French beans, Jatropa curcas and Colocasia, l.i.13 (W. H. Patterson); Accra, 

 on oleander and a creeper called " Salonica," 2. viii. 16 (Dr. J. W. Scott Macfie). 

 Southern Nigeria : Ibadan, on cacao seedlings, S.xii.ll (A. D. Peacock). 



Phenacoccus insolitus, Green. 



Madras: Saidapet ; on egg-plant (Solatium melongena), 13.vii.07 (T. V. 

 Ramakrishna, per E. Ballard). 



Mr. E. E. Green in his original diagnosis (Mem. Dept. Agric. hid., ii, p. 2G, 1908) 

 states that the 8th and 9th segments of the antennae are " fused together." In 

 several of my examples this character is very pronounced ; in others, however, the 

 articulation is as clearly denned as the rest. 



Tachardia decorella, Mask. 



Uganda: Entebbe; on Anona muricata, heavy infestation, 20. hi. 13 (C. C. 

 Gowdey). South Africa : Pretoria, 1914 (D. d'Emmerez). 



Asterolecanium coffeae, Newst. 



British East Africa: on coffee plants seven miles N.E. of Nairobi, 9.xii.l2 

 (Geo. W. Evans). Uganda: Nakasanja, Chagwe, on coffee, 10.vi.13; Banda, on 

 coffee, 28.vii.16 (C. C. Goivdey) -heavy infestations. 



Mr. Evans, in a note attached to his specimens, states that this Coccid infests 

 every part of the tree, causing the leaves to droop. He found twenty plants 

 attacked by it. A small percentage of the specimens are infested by Chalcidid 

 parasites. The general colour of the tests of the females is pale yellowish-green. 

 In Mr. Gowdey's specimens the colour of the test of both old and young adults is 

 pale bottle-green, shaded with bright yellowish-green or golden green ; the filaments 

 forming the fringe, crest, etc., dull pink. In the adult females the anal lobes are 

 furnished with a single long bristle ; these had evidently been broken away in the 

 type material described by me in 1911.* 



Asterolecanium bambusae, Bdv. 



Gold Coast : Aburi; on bamboo (W. H. Patterson). Uganda: Entebbe; on 

 bamboo, 7.ii. 14 (C. C. Goivdey). South Africa : 1914 (D. d'Emmerez). 



Cerococcus hibisci, Green. 



C. hibisci, Green, Mem. Dept. Agric. India, ii, no. 2, p. 19, pi. ii (1908). 



S. India : Guntur ; on egg-plant, 20. hi. 10 (T. V. Ratnakrishna, per E. Ballard). 



The tests of the females agree best with those forms which are described by Green 

 (I.e.) as having a " golden-yellow scurfy tomentum," but the tomentum in my
