ADDENDA ET CORRIGENDA 



The discal cross-vein is placed near the middle of the discal cell in Spania 

 (fig. 208). 



Fig. 64 for " Nielson " read " Nielsen." 



Pachyijaster atra occurred at Bridgend in Glamorgan on August 6, 1908. 



F. Leachii was not uncommon near Orford in Suffolk about July 11, 1908. 



An examination of Meigen's original genus CUtelhiria proves it to have 

 been an absolute synonym of Ephlppium, and consequently the name 

 Adoxo7mjia should be adopted for the genus indicated here. 



101. Oxycera tenuicornis synonymy. Villeneuve has just (December 1908) 



imagined that he had found a new genus and species, Vanoyia scutellata, 

 in this fairly well-known fly, which was described from France by his 

 own compatriot (Macquart) more than seventy years ago. 



107. Oxycera pulchella. A male which was taken by Colonel Yerbury at 



Bridgend in Glamorgan on August 8, 1908, had the eyes in life dark 

 blue-green on the upper two-thirds but bronze-green on the lower third, 

 with a dark purple intermediate band. 



111. O. trilineata. A male which was taken by Colonel Yerbury at Dartford in 



Kent had the eyes in life bright blue-green on the upper facets but 

 yellowish green on the lower facets, with an orange intermediate band. 



118. Nemotelvs pantherinus. I have a record from Tarrington as early as 



May 13. 



119. 34. The words " large white spot " scarcely apply to the female. 



135. Odontomyia tiyrina. The eyes of the male range from this description to 



reddish coppery with an indigo-blue band which is margined with 

 yellowish green. 



163. Last 2. It is possible that the larvae of Sargus are carnivorous and feed on the 

 larvae of other insects which occur in any rotting matter. 



166. An examination of a large number of specimens of the " Sargus flavipes" 



group which were taken by Colonel Yerbury in Glamorgan about the end 

 of August, 1908, has not tended to clear up the species ; some of the large 

 males answer to my idea of ^'. rujipes, but all the large females show at 

 least a tendency towards a dark splash on the front femora, while the 

 small males (and perhaps one female) come under my .S. niddtis, the 

 medium sized specimens being true S. flavipes ; the natural conclusion is 

 that S. rujipes and 6'. nitidus (raihi) are only forms of the widely spread and
