312 AMERICAN HYMENOPTERA. 



the wiug but hardly traceable above. Radial area open and short. Areolet very 

 small, the upper side bounded by a longer vein than the others which gives it a 

 squat appearance, which is quite unique. The cubitus reaches half-way to the 

 first transverse. Body .10, antennae .09, wings 10. 

 Female, — Body .10; antennae .08; wings .11.

Amlricus parinula n. sp. 



Galls. — Minute, flat, saucer shaped, with a slight elevation in the 

 center. This central portion is the small larval cell. They are 

 sessile on the under side of the leaves of a species of oak unknown 

 to me. They are only .08 of an inch across the top, and are of a 

 fine red color. They are, in habit, very much like a species found 

 on Q. alba, but are very much smaller, and the white oak gall is a 

 pale blue color. I am not sure that the white oak gall has yet been 

 reared. There are several other species that somewhat resemble this 

 one. I received these galls from Mrs. E. H. King, of Napa City, 

 California. 



Gall-fly. — A female cut out of a dry gall. The crumpled wings and compacted 

 budy make description rather difficult. Head dark brownish red. Antennae 

 thirteen. jointed, first large, dark brown, second large, lighter color than the first, 

 the following shorter and gradually darker to the last five which are dusky 

 brown. Entire body bright red. Thorax finely punctate. Parapsides fine but 

 distinct, and diverging far less than in other species. Abdomen finely polished. 

 Legs red. Wings colorless, as are also the veins, except the second transverse 

 and the subcostal. Radial area is scarcely discernible, but is open. Areolet 

 wanting. Body. 08; antennae .07; wing .08. 



Andricus patiens n. sp. 



Fifty or more individuals captured in early Spring in the act of 

 ovipositing in the buds of Q. ilicifolia. They were taken when the 

 temperature was so low that a heavy overcoat was needed to keep 

 one comfortable, and a stiff northeast wind prevailed, and the buds 

 showed no signs of life. 



These insects must be strangely insensible to cold, or be driven 

 by an irresistible impulse to deposit their eggs, or they would not 

 brave such inclement weather. 



Gall-fly. — Head small, very dark red, hairy and rugose, vertex flattened. An- 

 tennae fourteen jointed, first dark, heavy and club shaped, second stout and one- 

 third the length of the first and of a lighter color; third equal to the first two; 

 fourth, fifth and sixth gradually shorter, the following short and of equal length. 

 All except the first are a dusky red, that under the magnifier becomes of a bright 

 coppery hue. Thorax and scutellum dull red and covered with extremely fine, 

 short hairs that really are little more than a coarse pubescence. Parapsides,
