 rather spiny gall on the upper surface of a Crataegus leaf taken at 

 Bath, N. Y. 



Gall. Fotir to 5 mm high, 1.5 mm in diameter, the tip fimbriate. 

 This is an irregular, rather spiny gall (pi. 12, fig. 2) on the upper 

 surface of the leaf, each containing a yellowish larva, the posterior 

 extremity being bright red. This species is probably an inquiline.

 body, rather thickly haired, fuscous yellowish, yellowish basally; 

 fourteen segments, the fifth with the stems three times their 

 diameters; distal enlargement pyriform, with a length one-third 

 greater than its diameter. Palpi; first segment probably quad-

 than the third. Face yellowish. Mesonotum light brown, the
