36 
(1899-1906, but chiefly in the years 1905 and 1906). In 
addition to these a relatively small number of uncatalogued 
specimens have been incorporated. The series contains 21 
Asilid flies, collected with great care, and a valuable addition 
to the general collection of this most interesting group. One 
hundred and fifty-four catalogued specimens of Aculeate 
Hymenoptera, 288 of Coleoptera, 177 of Rhynchota, and 
204 of Orthoptera—all of them with Mr. Guy Marshall’s 
admirable data—are a valuable accession to the collections of 
these Orders of insects. In addition to the above, Mr. Marshall 
presented 6 sets of the wings of Precis sesamus (Salisbury, 
1905), dissected out of the pupal case. The specimens are 
of great interest in showing an early stage of development 
of the pigment. 
Five hundred and seventy-five catalogued (and relatively 
few uncatalogued) specimens of insects of many Orders, 
from the Chirinda Forest, Melsetter, Gazaland, S.E. Rhodesia, 
3,600-4,000 ft. (Sept.—Oct., 1905). Of these no less than 
329 are Hymenoptera, other Orders being represented by 
relatively small numbers. Two beautiful Dipterous mimics 
of Aculeate Hymenoptera are included, together with their 
respective models, captured upon the same dates. 
Thirty-two Lepidoptera and dragon-flies from Mazoe, 
Mashonaland, 4,000 ft. (Dec., 1905). These include many 
Lycaenidae, greatly wanted by the Department, and several 
specimens which offer convincing indirect evidence of the 
attacks of enemies. . 
Small mixed collections of insects, chiefly. Orthoptera, 
from the following localities in S.E. Rhodesia (1995) :— 
Mangesi River, Manica, 3,000 ft. (Oct.); Mpudzi River, 
Manica, 3,000 ft. (Oct.); Mpudzi River to Amanzimhlope 
River, 3,000 ft. (Sept.); Inyanyadsi River, Manica, 2,500 ft. 
(Sept.); Mahakata River, Gazaland, 5,000 ft. (Oct.); Upper 
Buzi River, Gazaland, 3,500 ft. (Sept.); Umvumvumvu River, 
Gazaland (Sept.). The elevations are approximate. Altogether 
270 specimens from these localities are catalogued, in addition 
to a considerable number, chiefly Orthoptera, uncatalogucd.
