Weld. Later Mr. S. A. Rohwer kindly took a type of corallosa to 

 Philadelphia and made a direct comparison and confirmed this sus- 

 picion, so that the name of hadia must now be applied to the flies 

 and gall recently described as corallosa. This discovery adds the 

 further information to the life history that the fly of this root-gall- 

 forming species emerges in " early spring " and oviposits in the buds 

 of thrifty white oak sprouts, but the alternating generation is at 

 present unknown.

 AmphihoUps montana Beutenmueller, Insect Insit. Menst., vol. 1, 1913, p. 

 122. 

 The type of montana is in the collection of William Beutenmueller, 

 who also has another specimen of the same species loaned to the 

 writer for study in June, 1921. This agrees with the Ashmead type 

 of punctata which Dalla Torre renamed hignelli.

The following notes are made from the seven type females in the 

 United States National Museum. The four with unbroken antennae 

 show 15 segments. The sides of pronotum are slightly reticulate: 

 mesoscutmn coriaceous, as long as broad, parapsidal grooves com- 

 plete. Transverse groove at base of scutellum scarcely divided into 

 distinct pits. Carinae on propodeum bent outward. Fore wing 

 short brown pubescent ; the hairs on hind margin slightl}'^ longer than 

 those on surface, but much shorter than normal cilia. Venation 

 complete; areolet distinct; cubitus reaching basal below middle. 

 Claws weak and simple. Abdomen higher than long, shorter than 

 head and thorax ; ventral spine not longer than broad. Using width 

 of head as a base, the length of the mesoscutum ratio is 1.22, antenna, 

 2.08; ovipositor, 5.25; wing, 3.2. It is a Callirhyfh related to those 

 other species of this genus bred from flower galls. In the collection 

 there are also tAvo males, which are undescribed. 



Male. — Similar to female in color and sculpture. Antennae 16- 

 segmented, wings normally ciliatc; abdomen triangular, shorter than 

 thorax. Length 1.7-1.8 mm. 



The writer has collected galls of this species at Los Angeles, Pasa- 

 dena, Santa Anita, Camp Baldy, Newhall, Piru, in Ojai Valley, 

 Carpinteria, Montecito, Santa Barbara, Santa ISIargarita, Paso 

 Eobles, Soledad, Monterey, Los Gatos, Palo Alto, ^Monnt Tamalpais,
