a pair of Mutillids taken zz coztw, 7 Coleoptera, 19 Neuroptera, 
and r Orthopteron were presented by Guy A. K. Marshall, 
Esq. The specimens were captured in the following localities 
in Natal:—Estcourt, 4—5000 ft. (1896) ; Niginya, Ulundi, near 
Estcourt (5,800 ft.), and Ulundi (5,coo ft.); Tugela River, 
near Weenen, 2,500 ft. and 4,000 ft. (1896) ; Weenen (1896) ; 
Chuga’s Hill, near Weenen, 4,000 ft. (1896); Loskop, Little 
Tugela River, 4,500 ft. (1896); Karkloof, 4,200 ft.; Frere, 
3,800 ft. (1896); Port Shepstone, sea level (1897); Durban, 
and the following localities near it :—Berea, 500 ft. (1897); 
Malvern, 800 ft. ; Claremont, 200 ft. (1897) ; Northdene, 800 ft. 
(1897); Isipingo, sea level (1896); Sydenham, 400 ft. (1897) ; 
the Palmiet River. 
In addition to the above important accessions to the general 
collection the bionomic series owes to Mr. Marshall the fol- 
lowing additions, from Natal :—A magnificent Ichneumonid 
mimic of a Fossorial wasp (.Sa/ius) from Estcourt (Nov. 1896) ; 
4 Asilid flies with their prey—a beetle (Malvern, Nov. 1902) ; 
a bug, a Cicada, and a species of Asilid smaller than its 
captor (all from Estcourt, Nov. 1902); a Chalcid parasite bred 
from the pupa of the Pierine butterfly, Belenots mesentina 
(Natal only). 
In 1896 Mr. Marshall conducted an interesting series of 
experiments upon Pierine and Nymphaline butterflies for the 
purpose of testing the power of climatic conditions (moisture 
and temperature) to produce the seasonal phases which are 
known to occur in nature. <A large part of this material was 
presented to the University Collections many years ago, and 
formed the material upon which a part of Dr. F. A. Dixey’s 
paper on “ Seasonal Dimorphism in Butterflies” was written 
(Trans. Ent. Soc., Lond. 1902, pp. 199-216). In 1902 Mr. 
Marshall presented the whole of the remaining results of these 
experiments which he had kept for his own collection. The 
specimens are as follows :— 
One Teracolus annae, 8, the pupa of which had been 
kept in a damp jar for the last nine out of the thirteen days of 
its pupal period (near Weenen, Tugela River), 2,500 ft. (1876).
