July, 1910. Its colour distiuguislies it at ouce iroxn flaviventris : dark 

 metallic blue, with 3'ellow maudibles, and the hiud tibiae partly white. 



Pamphilius. Two species have to be added to my Table, viz., 

 gyllenhali Dhlb., aud one which I believe to be vafer L. 



P. gyllenhali has been described in Ent. Mo. Mag., March, 1905. It conaes 

 next to betulae, having — like that species — the " frons" strongly bituberctilate, 

 but the head in the $ is black, with yellow markings (not red as in betulae), 

 the scutellum is yellow, and the abdomen has only a narrow (yellow) central 

 band. 



P. vafer comes next to depressus, from which it differs chiefly by its 

 smoother and more shining head, with a much feebler and less close punctura- 

 tion (especially in the $ ). It is also less copiously marked with yellow, but 

 the sculpture of the head is a more reliable character. Of this species I have 

 a (J from Sherwood Forest (Donisthorpe, June, 1907); another g, Avith no 

 stated locality, from Dr. Capron's collection, and a $ taken by myself at 

 Woking, on June 9th, 1914. 



P. paUipes, which I doubtfully included iu my Table, is certainly 

 British. Mr. Atmore has taken it more than ouce near King's Jjyun. 



P. balteatus and liortornm were stated by me to differ in the com- 

 parative lengths of the 3rd and 4th autennal joints. That character 

 is given by Konow, but I am unable to recognise it in my own speci- 

 mens. The 3rd joint appears to me more than twice as long as the 

 4th in both ! 



However, the two species are so differently coloured that there 

 can be no difficulty in separating them. 



No. 6 (November, 1903). 



Hartigia (= Macrocephus) linearis. Mr. Sheldon has kindly 

 given me many fine ^ ^ and $ ? of this sp., which he bred in June, 

 1915, from stems of Agrimonia eupatoria. 



H. satyrus. This species is called in several old collections ''niger 

 Harris," and if the identification be correct, niger is the older name. 

 But Harris's figure does not seem to agree with his description, and I 

 cannot recognise the characters of satyrus in either. On the whole, 

 I think that " Syrex niger Harris " must remain a mystery. The 

 species referred to it by Konow belongs to a genus (Eumetaholus 

 Schulz = Astatus Knw., nee Jur.) which, to the best of my belief, has 

 no claim to a place in the British fauna ; nor have I ever understood 

 on what grounds KonoM^ decided that this species w^iS th^, jtru^ .ni'jer. 

 (It is figured by Panzer as "Astatus troglodytus.'^). V
