Sargent in this region, but no adults were reared. A smoother gall 

 quite similar to the type of rhizoxenus in shape and size and color 

 occurs on Quercus reticulata Humboldt, Bonpland, and Kunth (Plate 

 32, fig. 14) (seen in the Santa Catalina and Huachuca Mountains) 

 but no adults were reared. As these always occur in the lower part 

 of the clump of bushes, within 1 or 2 feet of the ground, terminal 

 on the oak runner sprouts characteristic of this oak, it may well be 

 that it was galls from this oak, occurring under debris perhaps, that 

 were originally collected and described as root galls. The species 

 should be considered as producing a stem gall, not an underground 

 gall, and is treated in this paper merely to clear up the error in the 

 literature.

The gall was described as a twig gall by Cameron in 18S3 from 

 Chiriqui, Mexico, collected by a Mr. Champion. Later Doctor Duges 

 sent specimens of a large woody gall (the largest now preserved 

 measures 11 by 8 by 7 cm.) to Doctor Ashmead, who curiously 

 enough considered it to be a root gall and as such described it to- 

 gether with the maker under the name of Andricus chamqrioni. It 

 is a true Andricus, and the three types are in the United States Na- 

 tional Museum together with the nine galls and eight other flics from 

 the same locality not labeled as types. Thinking that this was a 

 root gall and hence different from Cameron's, the authors of the 

 Tierreich monograph gave it the new name of ashmeadi. As Craw- 

 ford has pointed out, however, Doctor Duges later wrote to Dr. L. O. 

 Howard that he had never sent any root galls to Ashmead, and the 

 specimens in the National Museum plainly show that they are twig 

 galls, and without doubt they are the same as those described by 

 Cameron. The species should then take the name which Ashmead 

 gave it and be credited to him, as he was the first to rear and describe 

 the maker. 



In August, 1910, the writer saw these galls (Plate 31, fig. 13) fairly 

 common on the oaks which grow on the higher slopes of the moun-
