A number of specimens of this peculiar form were reared in July 

 [907 from an oval cell formed by the adhesion of two Solidago 

 leaves about an injured area. Two species at least, develop in this 

 type of gall, the above named form and Asphondylia 

 monacha O. S. The exuviae of the latter form was found near 

 a large exit hole, while the Camptoneuromyia emerges through a 

 smaller orifice. Representatives of both genera were reared from 

 different lots of galls and in one case the puparium of an Asphondylia 

 was observed within the deformity. A peculiar larva, probably a 

 Lestodiplosis, was taken from one gall. 



The formation of this gall is interesting. It evidently originates 

 in the closely appressed terminal leaves of growing buds. The 

 female presumably inserts her long ovipositor between the young 

 leaves, deposits an egg there and the irritation caused by the develop- 

 ing larva results in the leaves adhering, even after subsequent 

 growth of the plant has separated the bases of the two leaves an 

 inch or more. Interesting gradations showing the development of 

 the gall of this somewhat local species were observable at West 

 Xyack, July 17, 1907. This gall has been observed at Nassau, 

 N. Y., and by Prof. J. G. Needham in the Adirondacks. 



Gall. The gall produced by this species is an 

 irregular, subglobular swelling involving both 

 leaves. It is approximately oval in shape, about 

 2 mm in diameter and may contain one or two 

 whitish larvae. 



Larva. Length 2.5 mm, whitish or yellowish 

 white, slender, smooth; head small; antennae 

 minute. There is no breastbone visible in the Fig. 46 Campto- 

 mounted specimens, possibly due to a recent neuro m y i a a d - 

 molt or to the larva being in an early stage. hesa, fifth anten- 

 Terminal segment broadly rounded, with a pair nal segment of the' 

 of submedian, stout, irregular tubercles and a male, enlarged (orig- 

 long, slender, lateral seta near the middle of inal) 

 each segment .
