what longer account of its life-history, and Eckel (3) gives 

 it still more in detail. 



Felt (5) in an article on this species compiles largely from 

 the last writer. Aside from a few notes by other writers, this 

 is the extent of the literature relating to his eastern midge. 



The Californian species recently found inhabiting the resin- 

 ous exudations of the Monterey pine is somewhat larger than 

 its eastern cogener, and differs from it in other respects, both 

 in the larval and imaginal stage. I place this new species in 

 the genus Cecidomyia, adopting the .generic distribution of 

 Kertesz, which Aldrich uses in his "Catalogue of North Amer- 

 ican Diptera" (1905). 



Gecidomyia resinicoloides n. sp. 



Male. Length of body 4 mm., alar expanse 9-10 mm. Antennae 2 plus 

 24 jointed, not much shorter than body, of dark color except scapus, 

 which has grayish-red tinge; flagellum with small subglobular joints 

 alternating with double subcylindrical ones; pedicels between the joints 

 about equal to the diameter of the shorter joints, somewhat longer 

 towards the end of the antennae; joints verticillate, the length of the 

 hairs of the verticils much longer than the shorter joints, and the 

 longer ones slightly longer than the double joints; end of flagellum 

 recurved dorsally almost into a circle. 



Female. Length of body 5.5 mm., alar expanse n mm. Antennas 

 2 plus 12 jointed, less than half as long as body, joints of flagellum sub- 

 cylindrical, more than twice as long as broad, the basal ones longest; 

 pedicels short, the hairs clothing the antennae are slightly shorter than 

 each single joint, with here and there one fully as long. Antennae 

 slightly upcurved. The black eyes in both sexes confluent above, oc- 

 cupying the whole surface of the head except a space around and below 

 the antennae and a portion of the occiput, which parts are brownish 

 red. Some recurved blackish hairs arising from occiput, also a small 

 bunch on frons below antennae. Ground color of thorax grayish with 

 slight brown or reddish-brown tinge (varying in intensity according to 

 age) with the base of the wings and the sutures reddish, which color 

 predominates generally in freshly emerged specimens, darkest on the 

 dorsum with sparse bristly black hair, a row of which runs along a 

 blackish stripe on each side of the median line of the scutellum, con- 

 verging slightly posteriorly and then diverging and becoming more ob- 

 scure. Viewed in another light this line is broken into an anterior and 

 a posterior stripe and a short posterior median band. The light con- 

 trasting ground color brings out an apparent yellowish-gray stripe on
