Three papers on W. J. Burchell and his collections in the 
Hope Department appeared in the early part of 1904, and 
were described in last year’s Report. One part of a fourth 
paper on the first three sub-families of Brazilian butterflies, 
by Miss Cora B. Sanders, of Lady Margaret Hall, appeared in 
April, the second in May (Ann. Mag. Nat. Hist., pp. 305 and 
356). An introduction and notes were contributed by the 
Professor, while Professor Westwood’s manuscript catalogue 
and notes were also incorporated. Commander Walker kindly 
aided in seeing these papers through the press, a task greatly 
increased by the immense number of dates and figures. 
The first important memoir on the Majorcan collection, 
made by Mr. Holland, Mr. Hamm, and the Professor in Igo1, 
was published in the course of the year, being an account of 
the Hymenoptera Aculeata by Mr. Edward Saunders, F.R.S. 
(Trans. Ent. Soc. Lond., 1904, pp. 591-665). The paper also 
included the Aculeates captured in Spain on the same expedi- 
tion, and by the Professor in 1902. In the mainland collection 
205 species were recognized, in that from the island 143; but 
the latter included 5 species new to science—Pompilus poultont, 
Mimesa palliditarsis, Halictus hollandi, H. hammi,and H. dubi- 
tabilis. Of these, only the last-named occurs in the mainland 
list. The Professor contributed introductory accounts of the 
expeditions, notes on some of the species, and an Appendix 
on the mimetic resemblance borne by certain Diptera to the 
stinging Hymenoptera. The preparation of the paper and the 
correction of the proofs brought a great deal of work upon 
Mr. A. H. Hamm. 
The chief results of Mr. G. F. Leigh’s paper upon the breed- 
ing of Papilio cenea and Hypolimnas misippus have been already 
described (p. 18). The paper appeared in Trans. Ent. Soc. 
Lond., 1904, pp. 677-691. The Professor contributed notes, 
and Mr. Roland Trimen, F.R.S., an Appendix, on “ The merope- 
group of the genus Papilio.” The photographs from which the 
two very successful half-tone plates were executed were taken 
by Mr. Alfred Robinson.
