Mttilaspis ficus Sign. 



Newstead does not appear to have found male puparia of this 

 species in England. I find them occurring plentifully on twigs of 

 edible fig, sent to me by Prof. Lefroy at the end of Januai'y. They 

 are assembled more particularly on the younger branches. Newstead 

 writes that " the puparium is said to resemble that of the female, but 

 is smaller and whiter." This description is correct, the whitish male 

 puparia being in conspicuous contrast to the bark-coloured females. 

 The hinder part, posterior to the ' hinge,' is translucent. It is long 

 and narrow, approximately parallel- sided, with an average length of 

 1.50 mm. Most of the puparia were empty. A few contained 

 nymphs, but these dried up without producing adult males. 



Signoret gives a misleading account of the male puparium, which 

 he describes as " rounded and resembling the scale of an Aspidiotus, 

 that is to say, rounded, with the pellicle more or less central." He 

 also describes its colour as being " blackish grey." Leonardi sinks 

 the name ^cws as a synonym of conchifnrmis. 



Paelatoria pebgandbi Comstock. 



Newstead remarks of this species, " exceedingly common on 

 imported oranges in this country," but I have never met with it on 

 cultivated plants. Mr. Fryer has sent me specimens from Citrus 

 plants growing in a nufsery at Kingston.
