captured at a “‘ Cremastogaster-tree ” at Moor Plantation, 
near Ibadan, on Dec. 14, 1917, and the 3 was being 
fed by an ant received in the same consignment—a worker 
of Cremastogaster buchneri, near alligatrix, if not actually 
this race. Of the 5 9, 2 are in the Coll. Brit. Mus. 
The second consignment consisted of 5 3 (2 in Brit. 
Mus.) from the same locality, Aug. 10, 1918, accompanied 
by a sample of the ants which were feeding them. This 
worker ant was also near the race alligatriz. Similar 
workers were being robbed by the Cecidomyid Farqu-

harsonia rostrata, on the same date (pp. 440-42). The 
ants were kindly compared by Mr. W. C. Crawley and 
Mr. A. H. Hamm with speeimens named by Dr. Forel. 
The 5 9 in the first consignment offer sufficient evidence 
that this sex.as well as the other is fed by the ants. Mr. 
Donisthorpe tells me that Dr. Jacobson does not mention 
the sexes of those he observed being fed by ants in Java. 
Dr. Eltringham has kindly traced and made available for 
reproduction in text fig. 6, a hurried sketch in Farqu- 
harson’s letter of Dec. 23, 1917, quoted in Proc. Ent. Soc., 
1918, pp. xxxiv-xxxv. The record of so accurate an 
observer, who had just carefully studied the insects in 
life, is well worth preserving.—H.B.P. |
