tached to the walls of the gall. This species is separated from L. 

 hccate Felt by the shorter distal palpal segment. 

 Lasioptera diplaci, new species. 



Larva. — Length 2 mm. moderately stout, salmon colored. Head moderate. 

 Antennae slender, with a length 3^ times the diameter; breastbone tridentate, 

 the median tooth small, the shaft distinct and expanded anteriorly and pos- 

 teriorly. Skin coarsely shagreened ; posterior extremity narrowly rounded. 



Female. — Length 2.5 mm. Antennae extending to the base of the abdomen, 

 sparsely haired, black; 18 segments, the fifth with a length three fourths its 

 diameter; terminal segment somewhat produced, with a length 2 to 2 J/2 times 

 its diameter. Palpi ; first segment subquadrate, the second narrowly oval, 

 with a length over twice its diameter, the third one half longer than the 

 second, slender, the fourth a little longer and more slender than the second. 

 Mesonotum black, submedian lines with sparse fuscous hairs. Scutellum 

 fuscous whitish on the margins. Abdomen black, segments i to 6 with sub- 

 median oval, white spots posteriorly ; venter suffused with white scales.

 the terminal lobes narrowly oval, with a length about thrice the width and 

 thickly setose. Wings hyaline, the third vein uniting with costa near the 

 middle. Legs black, the first and the base of the second to fifth tarsal seg- 

 ments white. Claws slender, strongly curved, unidentate, the pulvilli as long 

 as the claws. Colors from Timberlake. Type Cecid 32314. 



This midge was reared November 24, 19 10, from ovoid stem en- 

 largements on Diplacits Jongiflonis collected by P. H. Timberlake in 

 the Puente Hills, Whittier, Cal. This species is closely allied to the 

 preceding. 



Asphondylia diplaci, new species. 



Gall. — This is a cabbage-like, densely woolly, apical growth of modified 

 leaves having a diameter of about 14 mm. 



ExuvicE. — Length 4.5 mm., moderately stout; cephalic horns short, ob- 

 liquely truncate and indistinctly dentate ; antennal cases extremely long, leg 

 cases extending to the fifth abdominal segment, wing cases to the third; 

 dorsum of abdominal segments with three well developed transverse rows of 

 stout, chitinous spines, the anterior two somewhat irregular, anteriorly a 

 rudimentary fourth ; terminal segment with 4 submedian pair of moderate 

 sized stout spines and two pair of larger lateral spines. 



Male. — Length 4.5 mm. Antennae probably nearly as long as the body, 

 sparsely haired, blackish; 14 segments, the third with a length five times its 

 diameter, the fifth with a length four times its diameter. Palpi ; first seg- 

 ment short, irregular, the second with a length four times its diameter, the 

 third slender and one-half longer than the second. Mesonotum grayish black. 

 Scutellum reddish, abdomen grayish black with a grayish white pubescence. 

 Wings hyaline, narrow, with a length 2^/2 times the width. Legs red, not
