were also younger females in different stages of development. Others 

 examined October, 1880, showed that all the females were living and that 

 the younger larvae- were present, but no eggs were found. The species 

 thus seem to hibernate in the mature female condition and to be both 

 oviparous and viviparous. 



Aspidiotus aurantii Mask. Cal. Both oviparous and viviparous ; 

 Hibernates as adult female. 



Aspidiotus rapax Comst. On Euonvmus, Orange, etc. ; Florida and 

 California. Observations made from March to the end of June indicate 

 that this species hibernates in the adult female, in the egg state, or as re 

 cently hatched larvae. 



Aspidiotus sabalis Comst. On Palmetto; Florida. The records indi 

 cate that this species hibernates both in the adult female and larva states. 

 Mature males were also observed March 23, 1883, but no eggs are recorded. 



Aspidiotus ancylus Putn. On various species of trees; District of 

 Columbia. Hibernates as half-grown female and as male larva, the male 

 appearing in March and April ; eggs unknown. 



Aspidiotus, n. sp. On Camellia; California. Hibernates in the adult 

 state, but numerous eggs are found the latter part of the winter. 



Aspidiotus, n. sp. On Japanese tea-plant; California. Hibernates in 

 the adult female state, the eggs being produced the latter part of the 

 winter. 



Diaspis boisduvalli Sign. On Livingstonia ; D. C. Adult females 

 with eggs and younger females in different stages, male pupae and adult 

 males, were all observed as late as November 12. 



Diaspis lanatus Morg. and Cckl. On Peach ; Florida. Mature females 

 hibernate without eggs; eggs are, however, found during the latter part 

 of June, probably of the second generation. 



Diaspis roscz Sandb. On Rose, etc.; D. C., Florida, California. 

 Specimens received from Florida February 20, 1880, embraced adult and 

 partly grown females, adults with numerous eggs, some of which were 

 hatching. Males were at the same time swarming. By April 20 adult 

 females and eggs were still present, though the males were absent. 

 Specimens of the same species received from California February 7, iSSi, 

 showed that the females were about half-grown and the males fully devel 

 oped. The same species from Washington, examined March 6 of this 

 year (1893), showed adult and half-grown females, the majority, however, 

 being in the egg state. 



Diaspis carueli Targ. On Juniperus, etc. ; D. C. Hibernates in the 

 adult female state, no eggs having so far been found. 



Chionaspis pinifolii Fitch. On Pine. Oviparous; hibernates in the 

 egg state. 



Chionaspis biclavis Comst. On Camellia; D. C. Oviparous; appears 

 to be a continuous breeder. 



Chionaspis quercus Comst. On Oak; California. Oviparous; hiber 

 nates as partly grown female, or as adult female, though the male larvae 

 and pupae have been observed as late as August.
