the dwarfed branches, the larvae living within the center of the small folded 

 leaves. 



Larva. — Length 2.75 mm. moderately stout, probably yellowish orange. 

 Head moderate, the antennae short, stout ; breastbone moderately well chiti- 

 nized, broadly and triangularly emarginate, the lateral angles short and acute. 

 Skin nearly smooth, posterior extremity broadly rounded and with two pair 

 of obtuse, rather inconspicuous submedian tubercles. 



Male. — Length 2.25 mm. Antennae as long as the body, sparsely haired, 

 light brown; 14 segments, the fifth having the stems with a length 2 and ij4 

 times their diameters, respectively ; terminal segment slightly reduced, basal 

 portion of the stem shorter than the basal enlargement, the distal enlarge- 

 ment subglobose and with a moderately long, stout appendage apically. Palpi ; 

 first segment subquadrate, the second probably nearly as long as the third, 

 which latter has a length thrice its diameter, the fourth one fourth longer than 

 the third and somewhat dilated. Mesonotum black, the submedian lines yel- 

 lowish. Scutellum blackish brown, postscutellum and first abdominal segment 

 blackish, the others yellowish brown. Abdomen sparsely clothed with long, 

 blackish hairs. Wings hyaline, costa light brown. Legs including coxae light 

 yellowish brown, thickly clothed with black hairs. Claws moderately stout, 

 strongly curved, the pulvilli longer than the claws. Genitalia ; basal clasp 

 segment stout, tapering ; terminal clasp segment rather short, stout ; dorsal 

 plate short, broad, very deeply and triangularly emarginate, the lobes diverg- 

 ing, setose ; ventral plate apparently very similar. Harpes somewhat 

 chitinized. 



Female. — Length 2.5 mm. Antennae extending to the fourth abdominal 

 segment, sparsely haired, light brown ; 14 segments, the fifth with a stem 

 one third the length of the subcylindric basal enlargement, which latter has 

 a length three fourths greater than its diameter ; terminal segment some- 

 what produced, with a length about thrice its diameter, irregular apically. 

 Mesonotum fuscous, nearly black anteriorly, the submedian lines and pos- 

 terior median area fuscous yellowish or reddish. Abdomen dark cherry 

 red, sparsely haired on the posterior margins of the segments and laterally. 

 Coxae light brown. Legs light yellowish, the femora apically golden, the 

 distal half of the front and the base of the middle and hind tibije, metatarsi 

 and last tarsal segments covered with light-colored hairs. Ovipositor nearly 

 as long as the body, moderately stout, the terminal lobes slender, tapering 

 irregularly apically; color characters after Timberlake. Type Cecid a23ii. 



Several specimens of both sexes were reared in December, 1910, 

 by Mr. P. H. Timberlake from rosette galls on Zauschneria calif arnica 

 collected in the Puente hills back of Whittier, Cal. The galls were 

 reported as being abundant everywhere through the hills. This 

 species is separated from T. hudsonici Felt by the longer basal portion 

 of the stem of the fifth antennal segment and the relatively shorter 

 fotirth palpal segment.
