346 THE CANADIAN ENTOMOLOGIST 



Andricus myrtifoliae, sp. nov. 



Female. — Pale, uniform yellowish brown, legs and antennae 

 paler. Head opaque and finely punctate. Antennae 13-jointed, 

 basal joints filiform, terminal ones stouter and much shorter. 

 Thorax opaque, evenly and finely punctate. Parapsidal grooves 

 fine, continuous and converging at the scutellum. Lateral grooves 

 indistinct. Anterior parallel lines very fine. Median groove evi- 

 dent only for a short distance at the scutellum, wanting anteriorly. 

 Pleurae wholly punctate. Scutellum opaque, finely rugoso- 

 punctate, with two broad, deep, almost contiguous, basal foveae. 

 Abdomen smooth and shining. Wings delicate, hyaline with' the 

 veins very faint. Radial area open at the costa. Cubitus con- 

 tinuous. Areolet not evident. Length 1-L25 mm. 



Gall. — \n clusters on the blossoms of Quercus myrtifolia 

 Monothalamous. Small, cone-shaped bodies, each containing a 

 single larval cell. When dry the gall is dark brown or almost 

 black. At the point of attachment it is flattened, and from this 

 part it gradually tapers to a blunt point at the apex. Length 

 2.50-3 mm. 



Habitat. — Jacksonville and Palat Ka, Fla. (Lewis H. Weld.) 

 The galls of this species were collected by Mr. Weld in April, 

 1914, and the flies emerged in a paper package and were all dead 

 when he unpacked his Florida material in July, 1914. Mr. Weld 

 informs me that the galls looked about the same in colour when 

 they were collected, but they may be greenish when they first ap- 

 pear. The male is black with pale, yellowish brown legs and 

 antennae. The latter is 15-jointed, with all the joints stouter, 

 the 3rd excavate beneath. 



Andricus gemmiformis, sp. nov. 



Female. — Head black, face very finely and minutely granulate, 

 cheeks almost smooth. Antennae 13-jointed, brown, paler at the 

 junctions of the joints in certain lights, four terminal joints black. 

 Thorax rufous, with a broad, black band from the collar to a little 

 beyond the middle, and a similar band outside the parapsidal 

 grooves extending forward to beyond the middle. Finely and 

 closely punctate, subopaque. Parapsidal grooves subparallel, 

 continuous, sharply defined and not much wider apart at the
