the following prey — Pyrameis cardui, L. ; female Melanargia 

 galatJiea, f.g. lucasi, Rambur; Eristalis tenax, L. ; a species of 

 Anthrax (p. iv). Four females with male and female Pararge 

 megaera, L. ; Sferrha sacraria, L. ; a female Sarcophaga (much 

 greased). 



The males of two unidentified species, one with a male 

 Sarcophaga (much greased), the other with a Cicada (p. iv). 



Hij)pobosca camelina, Leach. — Two specimens — one typical, 

 the other the dark Algerian form named drotnedarina by 

 Speise. Dr. Seitz sends the note " Caught on my back. 

 Very troublesome to horses. Alights flying on the back of the 

 horse and then runs very quickly and in a direct line to the 

 anus, where it rests." 



Exoprosopa pygmalion, F. — " A curious effect is sometimes 

 produced by this Anthracine — as if it were flying sideways." 



Bomhylius boghariensis, Lucas. — " This beautiful species 

 flies in April and May, disappearing in June when the other 

 Bomhylidae become abundant." 



Physegaster niacidatus, Macq. A pair taken in cop. — Con- 

 cerning this interesting Oncodid (Cyrtid) fly Dr. Seitz wrote : — 

 " This fly is not common : it hovers in spider-holes under the 

 ground. The female, when settled, looks somewhat like a 

 spider. The head is nearly aborted, so that the thorax 

 resembles the cephalothorax. The legs too are held like those 

 of a spider. The male does not bear any such resemblance." 

 Further observations on this species by Dr. Seitz will be 

 found in Proc. Ent. Soc, 1913, pp. xlix-1. 



W. A. Lamborn's further notes on the Driver Ants 

 (DoRYLUs) OF Southern Nigeria. — Prof. Poulton read 

 some further notes received in letters from Mr. Lamborn, and 

 exhibited the Diptera (all dated Dec. 10, 1913) referred to, 

 which had been kindly determined by Mr. E. E. Austen. 



The material of the genus Zonochroa, in the British Museum, 

 was divided into a large number of species, but only three 

 of these had been as yet determined, and these did not include 

 any one of the three species sent by Mr. Lamborn. Mr. Austen 

 had informed Prof. Poulton that nothing was known of the 

 bionomics of Zonochroa, and therefore the following notes 

 became of much interest.
