[July iSgs. 



joints vary in tiie tlifterent specimens of 

 tiie s.ime species even to a greater 

 degree than the above authors state 

 exists between Cneplinlia and Spallan- 

 zania, the former cannot be maintained 

 even in the sense of a sub-genus, but 

 must be considered a synonym of 

 Spallanzania. 



The species referred to above as 

 having been assigned to Acroglossa by 

 Giglio-Tos, is evidently the form pre- 

 viously described by Van der Wulp as 

 Prospherysa vilis (Biol. Cent. Am., 

 Diptera, II, 121), which Brauer and 

 Bergenstamm make the type of their 

 new genus, Chaetogaedia (1. c, V, 

 '\'\'o)- Giglio Tos remarks on the close 



resemblance between his species and 

 Fronthta acroglossoides Town., ; the 

 latter is a synonym of Bajimhaiieiia 

 analis V. d. W., and also belongs to 

 Chaetogaedia. 



The forms discussed above may be 

 listed as follows (synonyms in italics) : 

 Spallanzania Desv. Cnephalia Rond. ; 

 Acroglossa Will, 

 hesperidarum Will. (Acroglossa). 

 Pseudogonia rujicauda Town. ; 

 P. obsoleta Town. 

 Chaetogaedia B. B.

WOOLLY LEAF-GALL MADE BY A SPECIES OF CALLIRHYTIS 



ON SCRUB OAK. 



BY C. H. TYLER TOWNSEND, BROWNSVILLE, TEX. 



In the Can. Ent., 1893, p. 300, I 

 mentioned the breeding of a hymen- 

 opteron, determined by Dr. Rilev as 

 Andricus sp. (.'') from a woolly leaf- 

 gall on scrub oak, found in the Organ 

 Mts., Donna Ana Co., N. M. 



On Nov. 12, 1892, this gall was 

 found on scrub oak well up in the 

 Organ Mts., above the Modoc vine. 

 Sections that were opened on this date 

 contained pupae. The galls were also 

 noticed same date on sciub oaks at the 

 base of the same mountains, at Riley's 

 water. 



On March 16, 1S93, there were fountl 

 issued and dead, from galls collected 



Nov. 13, 1S93, eleven gall-flies of a 

 beautiful metallic green color. This is 

 the above species. There was also 

 found one specimen, larger in size and 

 of a flavous brown color, apparently dif- 

 ferent, which had issued with the rest. 

 The gall may be described as 

 follows : — 



<iall. — Diameter, about 12 to 15 mm.; 

 greatest heiaiht, 8 to 9 mm. On under side 

 of leaf, woolly subhemispherical or dome- 

 shaped in form, attached to the leaf by 

 small rootlets or stems on the basal flattened 

 surface, a stem to each principal section of 

 the gall. Color, pink externally, shaded to 

 slightly brownish or yellowish in mature or
