good as those imported. Caprifigs with 

 their insects have been repeatedly imported, 

 but attempts to establish the species have 

 not been very successful. The author re- 

 cently visited California and found Capri- 

 figs abundant in numerous places. He 

 thinks the time has come to carry on the 

 experiment in a larger way and believes it 

 will be successful. 



Notes on tlie Life History of Protoparce Caro- 

 lina. By Professor Wm. B. Alwood. 

 Breeding carried on with this species for 

 two years shows that it is slightly double- 

 brooded, at Blacksburg, Va. The earliest 

 moths appear June 7th-12th. Oviposition 

 begins June 20th ; larvaj moult 4 times, at in- 

 tervals of usually 4 days, become full fed in 

 20-21 days and enter the soil for pupation. 

 A small part of early brood issues as adults 

 the first year ; but the greater part are 

 single-brooded and appear as adults in July, 

 after passing the winter as pupaj. 



The Life History of Schizonetira lanigera Han- 

 sen. Hy Professor Wm. B. Alwood. 

 Breeding records show that the ' root and 

 stem forms ' can be colonized from root to 

 stem, or the reverse, and their natural mi- 

 grations were observed. Many of the 

 agamic wingless females at Blacksburg, 

 Va., survive the winter exposed on aerial 

 situations. Records show twelve genera- 

 tions of agamic, viviparous females from 

 May 12th to September 20th. At this date 

 winged, agamic, viviparous females were 

 produced in all the colonies observed. 

 These proved a migrant generation and 

 could not be induced to remain at rest on 

 the apple plant under control conditions, 

 but flew away. Under confinement they 

 produced 4-6 young, which were sexed in- 

 dividuals. These are small, beakless, with 

 rudimentary lobes where mouth parts 

 should be ; about ^- are males and | females. 

 After copulation females lay one egg, 

 which remains dormant overwinter. From 



long observations it is concluded that in 

 southern latitudes agamic individuals con- 

 tinue an unbroken chain, and that ovipa- 

 rous reproduction plays no important role in 

 the life cycle. Only a small per cent, be- 

 come winged, but on the contrary continue 

 as normal, agamic, wingless lice. 



The Phylogeny of North American Eucleidas. 



By Dr. Harrison G. Dyar. 



The Eucleidse is a family of moths rep- 

 resented by 28-31 species in this country. 

 The author is acquainted with life history of 

 20 species, and a partial life history of one 

 other has been published. LarviB offer 

 structural characters of value in classifica- 

 tion, and he presented a phylogenetic chart 

 of the 21 species where the young is known. 

 In the first division the lateral tubercle of 

 the first abdominal segment is lost. One 

 branch shows the origin of stinging spines. 

 In another branch the first division cor- 

 responds to the loss of the primitive first 

 stage, on the one hand, and to the complete 

 suppression of the many paired warts, on 

 the other. (To be published in Journal N. 

 Y. Entomological Society. )
