ing of one small, narrowly oval segment bearing one or more long, stout 

 seta. Mesonotum and abdomen black, shining; halteres yellowish basally, red- 

 dish apically. Legs a pale straw; claws moderately slender, strongly curved, 

 the pulvilli as long as the claws. Ovipositor nearly as long as the abdomen, 

 the terminal lobes narrowly oval. Type Cecid. 1627. 



Rhopalomyia salviae new species. 



The midges characterized below were reared by Mr. P. H. Tim- 

 berlake in May, 1912, from several collections of leaf galls on Salvia 

 (Ramojia) calif oruica and 5". nivca, collected in the Puente Hills near 

 Whittier, Cal. This gall was also collected by Professor E. P. Van 

 Duzee January 10, 1914, at Alpine, Cal. This species runs in our 

 key to near R. antcnnaricc Whir, or R. gnticrrczia Felt, from both of 

 which it appears to be quite distinct. 



Gall.- — Leaflets of 5". californica and presumably adjacent leaflets are 

 dwarfed by the formation of a conspicuous conical, minutely pubescent, grayish 

 brown, thick-walled gall having a length of i cm. and a diameter of .6 cm. 

 The structure appears to be a greatly thickened, hypertro'phied leaf, only rudi- 

 ments remaining, the walls being spongy and the interior containing an oval 

 larval cell with a length of about 3 mm. The midge evidently escapes through 

 an apical opening somewhat resembling that in the gall of Phyfophaga rigidce 

 O. S. A very different leaf gall, apparently produced by the same midge, 

 occurs on the margins of moderately well developed leaves. It is a typical 

 thin-walled, tubular gall with a length of about 6 mm., a diameter of 1.5 mm. 

 The interior is occupied by an elongate larval chamber. Basally the gall is 

 concolorous with the leaf, the distal third being purplish, the slightly curved 

 apex a little lighter. A modification of the first type of gall is seen on the 

 aborted leaflets of 5. nivea (or leucophylla). These galls are irregularly ob- 

 conical, with a length of about 7 mm., a diameter of 3 mm. and are more or 

 less confluent, otherwise nearly as described above. 



Exuvium. — Length 2.25 mm., mostly whitish transparent, the anterior 

 thickened portions of the head and thoracic structures brownish. Antennal 

 horns short, stout, indistinctly bidentate, the lateral process decidedly longer; 

 antennal cases extending to the base of the abdomen, wing cases to the third 

 abdominal segment, and leg cases to the fifth abdominal segment ; the posterior 

 extremity rather broadly rounded, the dorsal surface of the abdominal segments 

 thickly spotted with minute, chitinous points. 



Male.-^Length 2.5 mni. Antennae extending to the third abdominal seg- 

 ment, sparsely haired, the two basal segments black, the others dark brown ; 

 14 to 16 segments, the fifth with a stem three-fourths the length of the cylin- 

 dric basal enlargement, which latter has a length one and one-half times its 

 diameter; terminal segment reduced, narrowly oval. Palpi; first segment ir- 

 regular, with a length about twice its diameter, the second reduced, narrowly 

 oval. Mesonotum and scutellum black, naked. Abdomen mostly black, the
