iggeratod breadth of the interval 

 between the first and second bands, the position of the small 

 with regard to the posterior one had become altogether 

 distorted, and in order to correct this, he may have drawn the 

 smaJ. a second time, at a correct distance from the large 



one. Mr. V an der Wulp has erroneously taken Chsetopsii ■ ienea 

 for a Trypeta and, supposing it a new species;, accidentally de- 

 scribed it under the same specific name. 



ervatwH 2. — The Urophora ienea Macq. (Suites, etc., 

 Dipt II, p. 4o8, 13), may be a synonym of the present species, 

 although J do not consider this as certain. The figure of the 

 wing b in Dipt. Kxot. J I, '6, Tab. XXX, f. 7, shows at

 of the flattened ovipositor is comparatively long.
