K. NEWSTEAD — SCALE INSECTS (cOCCIDJi) 



?Diaspis chionaspiformis, Green, MS., sp. n. 



Female puparium creamy white : form like that of a typical CJiionaspis. 

 Pellii^les dusky reddish yellow. 

 Length averaging 1*75 mm. 



Male puparium apparently non-carinated, white ; forming dense masses 

 with innumerable threads o£ white flocculent secretion between them, some- 

 what like the colonies of the male puparia o£ Diaspis hoisduvalii, and they 

 are so arranged that they project almost at right angles to the branch. 



Female, adult, with the cephalo-thoracic region attenuated. Rudimentary 

 antennae with two long, curved^ spines. Anterior stigmata with 3-4 para- 

 stigmatic glands. Circumgenital glands in five groups. Formula of two 

 examples : —

Pygidium (fig. 10) well defined. Median lobes bilobed and united, the 

 lobules nearly equal in size ; 2nd and 3rd pairs angular and rudimentary. 



Fig. 10. — ? Diaspis chionaspiformis, Greeu ; margin of pygidium of adult female. 



Squamse spinose^ 3-4 on either side of the median lobes. Median pair o£ 

 spines stouter than those on other parts of the pygidium. Anal orifice 

 placed near the centre of the circumgenital glands. Dorsal pores numerous 

 on all the segments, especially so in the three thoracic ones. 



On an unknown plant ; Botanical Gardens, Entebbe, Uganda Protec- 

 torate, 18.xiJ0 [C. C. Gowdey, no. 1271). 



Easily distinguished by the united median lobes and the Cliionaspis-YikQ 

 form of the female puparium. It is an aberrant form and may subsequently 

 be placed in a subgenus of CJiionaspis. 



Aspidiotus cyanophylli, Signoret. 



Abundant on palms and sparingly on Antignon ; Uganda, 24 & 25.xi.10 

 (C C. Gowdey, no. xix.). 



This insect does not appear to have been recorded previously from Africa,
