206 ; September, 
and varied than elsewhere. T eollected in the smaller area, called the 
“Little Albufera,” adjoining the Bay of Pollensa in 1900, and again 
on two occasions, with Mr. W. Holland and Mr. A. H. Hamm, in July 
of the present year. We much wished to collect systematically in 
the larger and more. important tract visited by Mr. Thomas and Mr, 
Pocock, but the prevalence of malaria at Aleudia prevented us. Even 
at Pollensa, where there is a little malaria, we were regularly bitten 
by numbers of mosquitos every night (although, as Mr. Theobald 
informs me, the specimens we brought home were only Culea pipiens, 
L.), and finding that mosquito curtains were unknown at the Fondas 
in Alcudia, I decided that the risk was too great. Had I been aware 
of the conditions I should -have arranged to take portable mosquito- 
proof coverings. . 
From the above account it will be clear that only a small pro- 
portion of the indigenous insect fauna can now be looked for in 
Majorca. Excessive cultivation, continued from a remote historic 
period, cannot fail to have destroyed by far the larger number of the 
species. At the same time there is reason to hope that the remainder 
will exhibit many features of interest. 
Minorca is probably relatively much richer than Majorca. There 
is not that excessive devotion to agriculture which is so characteristic 
of Majorca, but grass is grown freely, and with it a varied and 
tolerably luxuriant vegetation. The surface of the island is much 
flatter and less interesting, the highest hill, Mount Toro, being only 
1150 feet. 
The first two sections, by Mr. Edward Saunders, contain an 
account of the Hymenoptera Aculeata and the Hemiptera collected in 
the spring of 1900 by Mr. Thomas and Mr. Pocock, and presented to 
the British Museum of Natural History, and those collected by me 
at the same time and presented to the Ilope Department of the 
Oxford University Museum. The specimens described below may be 
seen in these two Institutions. I have added a few notes of locality, 
habits, &e. The third section, by Col. J. W. Yerbury, will contain 
an account of the Diptera collected by the same naturalists at the same 
times and places as the //ymenoptera and Hemiptera. 
The following is an account of the route I followed in 1900. 
March 24th, 25th and part of 26th —Palma. Collected at Porto 
Pi, and especially in the grounds of Bellver Castle (150 to 400 feet), 
where flowers were very abundant. This was the most favourable 
locality I met with during the visit in 1900. Weather fine and sunny. 
March 26th and 27th—Valldemosa and Miramar. High ground
