Sept., I9I2.] Felt: New Gall Midges or Itonid.f,. 149 



haired. Scutellum yellowish, postscutellum yellowish brown. Abdomen yel- 

 lowish orange, the yellowish ovipositor nearly as long as the body, the terminal 

 lobes narrowly oval, setose. Wings hyaline, costa light straw. Halteres yel- 

 lowish. Coxae dark brown ; femora and tibiae pale straw, the tarsi mostly 

 fuscous straw, the pulvilli fully as long as the simple, moderately stout claws. 

 Type Cecid 32287. 



The female described above was reared by Prof. E. Bethel, Den- 

 ver, Col., from oval swellings at the base of pine needles. This spe- 

 cies can not be identical with Cecidomyia pinirigidce Pack., since the 

 latter has 14 pedicellate antennal segments, while the form charac- 

 terized has 16 sessile segments. It may be identical with an eastern 

 species forming similar galls on the scrub pine, Pinus virginiana and 

 bearing the name C. hrachynteroidcs O. S., an invalid designation, 

 zoologically speaking, since there is no description of an insect, and 

 not even undoubted evidence that Osten Sacken saw the larva re- 

 sponsible for the injury. This species is allied to /. nodosa Felt and 

 /. americana Felt, the short distal palpal segment separating it from 

 the latter and the color of the abdomen differentiating it from the 

 former. 



Asteromyia grindeliae, new species. 



Larva. — Length 2.5 mm., narrowly oval, probably yellowish orange. Head 

 "small, broadly rounded. Antennae short, stout ; breastbone short, broad, in- 

 distinctly tridentate, the middle tooth broadly rounded, the lateral tooth very 

 broadly and irregularly triangular ; shaft stout, densely chitinized and ex- 

 panded anteriorly and posteriorly ; segmentation indistinct ; posteriorly broadly 

 rounded ; skin coarsely shagreened. 



Male. — Length 2.25 mm. Antennae not extending to the base of the ab- 

 domen, sparsely haired, black; 13 segments, the fifth with a length equal to 

 its diameter. Palpi ; the one segment is narrowly oval. Mesonotum black, 

 the submedian lines with grayish scales and pubescence. Abdomen with the 

 four basal segments blackish, the three remaining, yellowish ; dorsum sparsely 

 covered with a mixture of black and gray scales ; venter with grayish scales. 

 Genitalia yellowish brown. Wings hyaline, the third vein uniting with costa a 

 little beyond the middle. Halteres yellowish transparent, the club fuscous bas- 

 ally. Coxas and femora blackish ; tibiae and tarsi reddish brown. Claws 

 moderately slender, strongly curved, unidentate, the pulvilli about as long as 

 the claws. Genitalia ; dorsal plate broad, deeply and roundly emarginate, the 

 lobes narrowly rounded and sparsely setose ; ventral plate short, broadly 

 rounded. Harpes moderately long with a stout, quadrate, chitinous tooth 

 apically. Color characters from Timberlake. Type Cecid 32319. 



This midge was reared July 27, 191 1, from blister leaf galls on 

 Grindelia robusfa collected by P. H. Timberlake near Santa Barbara,
