124 DRYOPHANTA LONG1VENTHIS. 



ventris, Grir. ; Bracon aterrimus, Ratz. ; and Orthostigma 

 gallarum, Ratz. Fitch (Ent., ix, 123) states Mr. 

 Rothera bred (as named by Mr. Walker) Eurytoma 

 nodularis, Megastigmus dorsalis, Gallimome elegans, and 

 G. antennatus. 



Sexual Form. — Black, very shining, impunctate ; scutellum opaque, 

 finely rugose ; very shortly and sparsely pilose ; pleurae shining, 

 impunctate ; legs yellowish or reddish -yellow, black at the base, the 

 femora infuscated ; wings hyaline, with a yellowish smoky tinge at the 

 base. $ and <$. 



Gall. — Found in the adventitious buds at the foot 

 of old oaks early in May. It is oval, rounded at the 

 apex, about 3 mm. in length, violaceous and velvety 

 when young, the latter quality being caused by the 

 surface being covered with microscopic whitish pile. 

 The shell is thin, the larva occupying the entire inte- 

 rior of the gall. When old, the violet tinge and the 

 velvety aspect disappear. Length 3 mm. 



Sometimes three or more galls are found touching 

 each other ; but they are also found singly. 



This gall has a considerable resemblance to that of 

 similis ; but it may be known from the latter by 

 being, as a rule, 1 mm. longer, by the apex being 

 broadly rounded, by the deeper violaceous tinge and 

 more distinct velvety texture, and by the surface not 

 bearing long white hairs. 



A gall apparently that of Taschenbergi was found 

 on Quercus cerris at Kew by Miss Ormerod, and is 

 figured, Ent., x, 43.
