26 OBSERVATIONS ON TINEINA. 



especially for the notice of Stathmopoda Guerinii, of which 

 I now send you five larvae." 



These larvae inhabited elongate, pod-like galls, formed on 

 the ends of the branches of the Pistacia terehinthus. These 

 galls contained many hundred Aphides, and appeared to be 

 formed by those insects. Along with them Dr. Staudinger 

 found larvae of one of the Phycidece, and these larvae of the 

 Stathmopoda Guerinii, which feed upon the inner walls of 

 the gall. 



With me the perfect insects began to appear on the 9th 

 of November, though with Dr. Staudinger they had already 

 begun to appear at least a fortnight earlier. 



In repose the insect erects its hind legs, and sticks them 

 out laterally, just as is done by Stathmopoda pedella ; yet 

 the difference in structure of the antennae, and in the form 

 of the hind wings, from what we find in Pedella^ is very 

 great. 



Since the able paper by Mr. Benjamin D. Walsh, of Rock 

 Island, Illinois, " On the Insects inhabiting the Galls of 

 certain Species of Willow," published in the 3rd volume of 

 the " Proceedings of the Entomological Society of Phila- 

 delphia," p. 543, more attention has been paid to the "other 

 insects which habitually breed in the galls formed by the true 

 gall-makers, and which, as they feed on the substance of 

 the gall itself, and only occasionally or incidentally destroy 

 the gall-making insect, may be appropriately considered as 

 Inquilines or Guest-flies." 



Amongst such Inquilines, Dr. Brackenridge Clemens has 

 described, in the same volume, pp. 506 — 508, three species 

 of Gelechittf namely — 



Gelechia gallcegenitellaf received from Mr. B. D. Walsh, 

 the larva mining the cabbage-like gall, brassicoides, peculiar 

 to Salix longijolia.
