Larva. — Length 2 mm., bright orange yellow, the breastbone reddish brown, 

 enlarged apically, tridentate, the teeth blunt and the middle one slightly the 

 longer. 



Male. — Length 2 mm. Antennae brownish black; 15 segments, the fifth 

 with a length three-fourths its diameter, the terminal segment slightly pro- 

 duced and obtusely rounded. Palpi ; first segment irregularly oval, moderately 

 stout, the second nearly as long and as stout as the first. Occiput densely 

 covered with black scales, the eyes margined with white scales and the face 

 with a few rather short, white hairs near the middle. Mesonotum probably 

 dark brown or black, the margins with groups of moderately long white hairs. 

 Abdomen black, the segments margined posteriorly with white scales; the 

 venter suffused with white scales ; genitalia black. Coxae black, with a spot 

 of white scales at the base ; femora mostly white scaled, black beneath, the 

 hind pair almost entirely white ; tibiae black above, white beneath ; tarsi black, 

 the segments annulate with white basally ; claws stout, strongly curved. Geni- 

 talia ; basal clasp segment moderately stout; terminal clasp segment long, 

 swollen basally ; dorsal plate moderately long, triangularly incised, the lobes 

 broadly rounded ; ventral plate long, broadly rounded. Harpes broad, tapering 

 sightly to a truncate apex bearing a stout, quadrate, chitinous tooth. 



Female. — Length 2 mm. Antennae with 16 segments, the fifth with a length 

 three-fourths its diameter; terminal segment apparently compound, composed 

 of two closely fused. Palpi ; first segment irregularly quadrate, curved, the 

 second a little longer, broadly fusiform. Ovipositor with a length about half 

 the abdomen, the terminal lobes broadly orbicular and sparsely setose. Type 

 Cecid. 1623. 



Asteromyia grindelise Felt. 



1912. Felt, E. P. N. Y. Ent. Soc. Jour. 20: 149. 



This species was first reared July 27, 1911, by Mr. P. H. Timber- 

 lake from blister leaf galls on Grindelia robusta collected near Santa 

 Barbara, Cal., and again October 20, 1915, from a greenish or black- 

 ish, oval, blister gall on G. cuneifolia collected in a salt marsh at 

 Milebrae, Cal. 



Gall. — The gall on G. cuneifolia is a typical greenish or oval, blister leaf 

 gall with a diameter of 3 or 4 mm. 



Male.- — The specimen reared in 1915 differs somewhat from that obtained 

 in 191 1, in that there are 15 antennal segments, the fifth with a length about 

 three-fourths its diameter, the terminal segment somewhat produced, compound 

 and with a length about one-half greater than its diameter; the abdomen with 

 the first four segments black and submedian whitish spots, those on the first 

 segment quadrate and on the others subtriangular and separated by a mod- 

 erately broad, black line; the distal segments vary from yellowish to reddish 

 brown. 



Female (previously unknown). — Length 2.25 mm. Antennae probably with
