Pupa. — Length 2.75 mm., stout, a variable reddish or yellowish, the thoracic 

 horns rather slender. Antennal cases extending to the first abdominal segment. 

 Wing cases to the third, and the longest leg cases to the fifth abdominal seg- 

 ment, each of the latter dorsally margined posteriorly with an irregular row of 

 rather long, stout spines. 



Female. — Length 2.5 mm. Antennae extending to the third abdominal seg- 

 ment, sparsely haired, dark brown, lighter distally ; 14 segments, the fifth with 

 a stem J4 the length of the cylindric basal enlargement, which latter has a 

 length 2^ times its diameter, sparse subbasal and subapical whorls of stout 

 setae and distinct circumfili ; terminal segment somewhat reduced, obtuse apically. 

 Palpi yellowish, first segment irregular, the second subquadrate, with a length 

 1/2 greater than its diameter, the third nearly twice the length of the second, 

 slender, the fourth about as long as the third, slightly dilated apically. Meso-, 

 notum slaty brown, the submedian lines thickly haired. Scutellum and post- 

 scutellum reddish brown, abdomen yellowish brown, the fifth and sixth segments 

 somewhat lighter, the incisures fuscous yellowish, yellowish apically. Costa fus- 

 cous yellowish. Halteres fuscous yellowish, fuscous subapically. Coxae and femora 

 basally fuscous yellowish, the distal portion of femora, tibiae and tarsi mostly 

 fuscous, the simple claw stout and a little shorter than the pulvilli. Ovipositor 

 filiform, as long as the body, the terminal lobes slender, tapering, with a length 

 five times the width. Type Cecid a2205a. 



A large, budlike deformity on Pinus scopnlonim was received 

 from Prof. E. Bethel, Denver, Col., July 24, 1911, and the same 

 gall from Prof. C. P. Gillette, of Fort Collins, Col. A species of 

 Dicrodiplosis, D. gillettei, was reared from this gall and also another 

 midge, probably a species of Coutarinia, which latter is described 

 above and is presumably the maker of the gall. 



Thecodiplosis dulichii, new species. 



i1/rt/<?.— Length 1.75 mm. Antennae a little longer than the body, thickly 

 haired, dark brown; 14 segments, the 3d to nth binodose, the Sth having the 

 stems with a length 1I/2 and 3l4 times their diameters, respectively. Basal 

 enlargement subglobose, distal enlargement subcylindric, with a length twice its 

 diameter, each with a very short, subapical circumfilium, the distal enlargement 

 with a rather thick subapical whorl of stout setae, and a scattering subbasal 

 whorl of finer setae; 12th segment with the enlargement scarcely constricted at 

 the basal third, the 13th and 14th each with a subcylindric basal enlargement, 

 having a length about three times the diameter, and a distal stem about ^ the 

 length of the enlargement. Palpi : first segment irregular, with a length twice 

 its diameter, the second twice as long as the first, the third a little longer than 

 the second, more slender, the fourth J-2 longer than the third, slender. Meso- 

 notum brownish red. Scutellum dark red, postscutellum and abdomen reddish 

 orange. Genitalia yellowish orange. Wings hyaline, costa light brown. Hal- 

 teres yellowish basally, reddish brown apically. Coxae mostly yellowish orange.
