Rhinocola eucalypti, Mask., is recorded from Suffolk on Eucalyptus. 

 It has baen reared through all stages at Oxford. Daring the summer 

 it lives outdoors on plants used for bedding purposes. Under glass, 

 this Psyllid may be controlled by fumigation.

This article briefly describes the life-cycle of the potato moth, 

 Phthorimaea operculella, Z., refers to its introduction into France 

 in the early years of the present century, and mentions the measures 

 usually employed against it, including the importation from the United 

 States of a Braconid parasite, Habrohracon johannseni, Vier. [R.A.E., 

 A, X, 8S]. At present no definite conclusions are available regarding 

 the establishment of this parasite.

This systematic study deals with 21 species that have been recorded 

 from the State. Further collection will probably reveal the existence 

 of several more. A remarkable number of cicadas appear to reach 

 one of the limits of their geographical distribution in Kansas, the 

 ■convergence of many species of varied distribution being undoubtedly 

 due to its central geographical position, to the extremes of its rainfall, 

 and to its varying elevation. 



An attempt has been made in this paper to determine the importance 

 •of various structural characters as aids in systematic work, especially 

 those of the ovipositor.

This handbook on the practical study of insects is not intended as 

 an introduction to their comparative anatomy or histology, but aims 

 at assisting the student in his early study of biology and the teacher 

 in the preparation of his subject. It also contains data helpful to 

 collectors. The present revised second edition contains a new section 

 on the Thysanura. Particular attention is paid to the Coleoptera, 

 Hymenoptera and Diptera that visit blossoms, and to insects of 

 agricultural and medical importance.
