200 THE CANADIAN ENTOMOLOGIST. 



One changed to a pupa in ground July 6, and another was at that date 

 burrowing in the earth. The two pupae were sent to Dr. Packard, who 

 wrote me under date of April 20, 1892, that one pupa had disclosed a 

 female moth, which proves to be probably this species. The other pupa 

 was a male and had not yet burst. May 22, 1892, half-grown larvae, 

 apparently this species, were found on willow. May 31 larger specimens 

 were found on cottonwood (P. fremontii). 

 Eucaterva variaria, Grote. 



This moth was bred from thin net-like cocoons found on terminal 

 shoots of Chilopsis saligna, August 25, the moths issuing Aug. 28. The 

 cocoon is very thin, formed of silk, with the nearest leaves fastened to it 

 on the outside. (See Psyche, April, 1892.) The moth is silvery, 

 speckled with blackish. I have noticed the Chilopsis, through September 

 and October, both near Mt. Picacho and about the entrance to Soledad 

 Canon, to be full of the empty cocoons of this moth. A tachinid was 

 bred from the cocoons about Sept. 5. (See Psyche, 1. c.) Determined 

 by Dr. Skinner. 



Hymenoptera. 

 Afidricus, sp. (?). 



While looking over, in March, specimens of plants collected the 

 previous summer, Prof. Wooton handed me some scrub oak leaves, one 

 of which possessed on the underside a reddish, woolly, hymenopterous 

 gall. Each section of the gall contained a perfect gall-fly, which had 

 transformed within, but had been unable to escape while the plant was in 

 press. Determined by Dr. Riley. The oak is Q. utidulatus var. 

 wrightii ; determined by Mr. W. H. Evans. 



Synergus, sp. (?). 



Scrub oaks (Q. uiidulatus var. wrightii) near Riley's water in the 

 Organ Mts. were found hung full of a large and very hard twig-gall about 

 the size of an apple. From a large gall which was brought home to breed 

 the flies, there issued, from April 6 to 20, about two dozen gall-flies. The 

 gall was 2 1/^ inches in longest diameter, and 2 inches in shortest. It 

 contained twenty-three exit holes April 20. The flies are brown or 

 blackish, with hyaline wings. Determined by Dr. Riley. 



Decato?na, sp. (?). 



From the last mentioned gall there also issued, on April 20 and May 

 19, two apparent inquilines of this genus. They are of a brownish 

 flavous colour, and the eyes are of a beautiful light carmine in life. De- 

 termined by Dr. Riley. 



Chalcididce (?). 



Prof. Wooton handed me in April a pod of a native species of Lotus, 

 with some chalcid (?) flies which had issued therefrom in his herbarium. 

 The pod is very small, and the plant was collected the preceding June. 

 The flies are black, and several holes in tlie pod show where they had 

 issued.
