310 PROFESSOR R. NEWSTEAD — NOTES ON 



Aspidiotus (Pseudaonidia) trilobitiformis, Green. 



Zanzibar : On baobab (Adansonia digitata), 20. v. 13 (2M W M. Aders). 



The puparia, all females, were arranged along the mid-rib of the leaf. Those 

 on the upper surface being much paler than those on the underside of the leaf, 

 owing apparently to the action of stronger light. 



Aspidiotus (Selenaspidus) articulatus, Morgan. 



British Guiana : Georgetown, on Liberian coffee and an ornamental palm, 

 23. vii. 12 (G. E. Bodkin). 



Uganda : Banda, Chagwe, on coffee, 14. xii. 12 (C. C. Ginodcy). 



The examples from Uganda were unusually large, many of them being twice 

 the size of those from the West Indies. 



Diaspis boisduvalii, Signoret. 



British Guiana : East Coast, 2. iii. 13, and Botanic Gardens, Georgetown, 

 on Cathy a super ba and plantain. 



Uganda : Entebe, on Baikea insignis and an unknown shrub, 6. iv. 13 and 

 1. v. 13 (C. C. Gowdeij). 



There are some very slight morphological differences between the African 

 examples and those found under glass in Europe, but I cannot separate them 

 specifically. 



Chionaspis citri, Comstock. 



British Guiana : Georgetown, ou lime and orange, 27. vii. 12 ( G. E. 

 Bodkin). 



Chionaspis funtumiae, ap. n. 



Female puparium. — Opaque white or pale ochraceous ; form usually broadly 

 dilated immediately behind the second pellicle. Larval pellicle dull yellow, with 

 a dusky median area ; second pellicle partly covered with a thin translucent 

 secretion. Ventral pellicle exceedingly thin and adhering to the plant. Length 

 2*0-2*9 mm. 



Male puparium opaque white or pale ochraceous ; non-car inated^ the texture 

 similar to that of the female ; sides slightly bulging, very narrowly pyriform or 

 rarely parallel. Occasionally it is slightly contorted or curved. Length 1*5- 

 1*6 mm. 



Female adult. — Markedly narrowed in front. Rudimentary antennae with 2-3 

 curved spines, one of them slightly stouter than the rest. Anterior pair of 

 spiracles with 5-6 pavastigmatic glands ; posterior pair usually with 2-3. 

 Proximal half of the margin of the thoracic area with numerous small pores ; and 

 many slightly larger pores on the abdominal segment. Genital orifice very slightly 

 in advance of the anal opening ; both organs placed proximally. Pygidium 

 (fig. 7) small. Median lobes large, widely separated, suddenly attenuated 

 distally, lateral margins faintly serrated, striae distinct, parallel ; second pair 

 of lobes duplex and unequal ; third pair somewhat rudimentary and sometimes 

 also duplex. Squamae spiniform and arranged in pairs between the lobes and 

 one pair beyond the latter. Spines minute. Circumgenital glands absent.
