June 18, 1914, several Schizoneuran migrants were observed on the 

 under side of the leaves of vi^ater shoots about apple trees in the yard 

 of the writer. A number of these, which were collected and examined, 

 turned out to be migrants from the elm leaf-clusters, which were very 

 numerous on young white elms just across the street to the east. These 

 lice were shrunken and appeared to have deposited all of their young, 

 but were still alive and active. An examination of the shoots re- 

 vealed a number of what appeared to be Schizoneuran larvae in the 

 axils of several of the leaves. These were in the first instar and just 

 beginning to show the characteristic wootly secretion of the woolly 

 apple louse. On the following Sunday, the 21st, an alate Schizoneuran 

 was taken in the act of depositing her young on the under side of an 

 apple leaf of the same trees mentioned above. There were three young 

 near her on the leaf and several others were found in the axil of the 

 leaf. This louse was also of the rosette type. 



Later, lice from a leaf cluster from the elm trees mentioned were 

 placed in a lantern globe cage in which there was an apple twig. These 

 lice appeared perfectly content on the apple leaves and were observed 

 to deposit their young almost as soon as placed in the cage. By July 

 5th the twig in this cage was nearly covered with young lice, which 

 were so covered with the woolly secretion as to make the twig nearly 

 white over its entire length of about six inches. At this point other 

 work prevented the completion of the experiment. From the results 

 of the work done the writer feels sure that Schizoneura lanigera and 

 the elm-curl louse are the same, the latter being the spring form of the 

 former. — Asa C. Maxson, Longmont, Colorado. 



Entomological Literature. 



COMPILED BY E. T. CRESSON, JR., AND J. A. G. REHN. 



Under the above head it is intended to note papers received at the 

 Academy of Natural Sciences, of Philadelphia, pertainins to the En- 

 tomologv of the Americas (North and South), includingr Arachnida and 

 Myriopoda. Articles irrelevant to American entomology will not be noted; 

 but contributions to anatomy, physiology and embryology of insects, how- 

 ever, whether relating to American or exotic species, will be recorded. 

 The numbers in Heavy- Faced Type refer to the journals, as numbered in 

 the following list, in which the papers are published. 



All continued papers, with few exceptions, are recorded only at their 

 first installments. . ■. . r. 



The records of systematic papers are all grouped at the end of each 

 Order of which they treat, and are separated from the rest by a dash. 



Unless mentioned in the title, the number of new species or forms are 

 given at end of title, within brackets.
