As regards the publication of researches, the year 1902 has 
been by far the most fruitful of any in the last decade. This 
is mainly due to the fact that the work of many previous 
years reached its culmination in the appearance of a memoir 
on the “Bionomics of South African Insects,’ by Mr. Guy 
A. K. Marshall and the Professor (Trans. Ent. Soc. Lond., 
1902, pp. 287-584, Plates IX-XXIII). The final arrangement 
of the manuscript of this publication was greatly helped by 
the presence of Mr. Marshall in England during the last 
summer, and his visits to Oxford. The chief part of Dr. Dixey’s 
paper on “Seasonal Dimorphism in Butterflies” (Trans. Ent. 
Soc. Lond., 1902, pp. 189-218, Plate IV) also dealt with. 
Mr. Marshall’s experiments and observations in South Africa 
in the years 1896-1901. A third paper by Mr. S. L. Hinde 
on “The Protective Resemblance to Flowers borne by an 
African Homopterous Insect” (Trans. Ent. Soc. Lond., 1902, 
pp- 695-698, Plates XXVI, XXVIJ), contained further obser- 
vations on the interesting “cluster of insects grouped to 
resemble a flower spike,” figured by Professor J. W. Gregory, 
in the “Great Rift Valley” (London, 1896), and in some 
respects corrected the conclusions of this naturalist. The 
plates are of the highest importance, being reproductions in 
“three-colour”’ and half-tone, respectively, of sketches of the 
perfect insects and the larvae in their natural surroundings 
made upon the spot by Mrs. Hinde. In this, as in the other 
memoirs, the described material is deposited in the University 
Collections, and the authors, when non-resident, have been 
in continual communication with the Department. These 
three publications have been issued as the third volume of 
“ Hope Reports,” which has just appeared. Inasmuch as these
