 Black ; abdomen reddish-brown below, blackisb above ; legs yellowish- 

 red, the coxa? brownish at the base ; antenna} brownish, the basal two 

 joints yellowish-red. Wings hyaline. Agamic $ . 

 Length 2£ — 3 mm. 



Gall. — Found in the terminal leaf -buds, half hidden 

 by the scales. Green when young, the shape an 

 elongated ova], with a wart or conical point at the 

 apex ; when young covered with a succulent matter, 

 giving it a brownish colour when old ; the inner gall 

 with longitudinal striations, not reticulations as in 

 globuli. When old the outer skin falls away. 



Found at the end of September and beginning of 

 October, and falls to the earth at the middle of the 

 latter month. 



It is shorter and more spherical than the gall of 

 collaris, but still being longer than broad ; the collaris 

 gall, too, wants the brownish succulent outer skin 

 found in autumnalis ; it is greenish, not brownish, the 

 conical point is more distinct, and there is no coloured 

 ring. From the gall of globuli it is easily known by 

 being longer than broad ; like it, it has a succulent 

 coat, but it does not become reticulated. 



The inquiline recorded by Mayr is Synergus nervosus, 

 and Schlectendal gives 8. variolosus, Htg., a species 

 not identified by Mayr in his monograph (S. E. Z., 

 1870, p. 343). Brischke records Synergus ruficornis 

 and S. apicalis. The latter authority gives Megastigmus 

 dor sails, Fab., as a parasite. 



The galls drop to the earth in October, the flies 

 coming out of them in April of the second year. 



Sexual Form. — Reddish-yellow, shining; the vertex finely shagreened; 

 the mesonotum finely punctured, dull ; the pleurse shining and impune- 

 tate, the abdomen above more or less brownish; antennae entirely 

 yellow ; wings hyaline.
