Rhabdophaga rosacea Felt 



1908 Felt, E. P. N. Y. State Mus. Bui. 124, p. 354 



The male of this species was received May 15, 1906 from Mr 

 Norman Criddle, Awema, Manitoba. The gall of presumably the 

 same species (C. 1268) was found September 30, 1907 by Mr L. H. 

 Weld, on a wild rose, Rosa, growing on low sand dunes at Beach, 

 111., near Waukegan. 



Gall. An apical loose bud gall some 2 to 2.5 cm in diameter and 

 3 to 3.5 cm long, the component leaflets rather loose, the general 

 appearance being somewhat similar to that of the pine cone gall on 

 willow, plate 11. There is an elongate central cell containing the 

 pinkish larva. 



Larva. Length 3 mm, stout, pale orange. Head small ; antennae 

 short, tapering ; breastbone obsolescent. Skin coarsely shagreened ; 

 posterior extremity slightly lobed. Larva from Illinois specimens 

 and tentatively referred to this species. 



Male 1 . Length 2.5 mm. Antennae extending to the third abdo- 

 minal segment, yellowish brown; 16 segments, the fifth with a stem 

 one-fourth the length of the basal enlargement, which latter has a 

 length twice its diameter; terminal segment reduced, narrowly oval 

 and sometimes fused with the preceding. Palpi; first segment pro- 

 duced, expanded distally, second with a length three times its width, 

 the third a little longer, more slender, the fourth a little shorter 

 than the third, dilated. Body probably reddish brown. Wings 

 hyaline, costa dark brown. Halteres probably yellowish and fus- 

 cous. Legs presumably fuscous yellowish, the tarsal segments 

 darker ; claws rather slender, strongly curved, the pulvilli longer 

 than the claws. Genitalia ; basal clasp segment long, stout ; terminal 

 clasp segment short, greatly swollen nasally ; dorsal plate deeply and 

 triangularly emarginate ; ventral plate rather short, deeply and 

 triangularly emarginate. Harpes rather broad, truncate, dentate. 

 Type Cecid. 1244. 



Rhabdophaga latebrosa Felt 



1909 Felt, E. P. Econ. Ent. Jour., 2 1290 



This species was reared at Albany, N. Y., May 7, 1909, presum- 

 ably from apparently normal willow buds, though the one bud show- 

 ing an exit hole did not appear as though it has been recently 

 deserted by a fly. This species was taken at Albany, N. Y. 



Male. Length 1.5 mm. Antennae as long as the body, fuscous 

 yellowish; 17 segments, the fifth with a stem three-fourths the 

 length of the basal enlargement, which latter has a length two and 

 one-half times its diameter ; terminal segment reduced, narrowly 

 oval. Palpi; first segment irregular, rectangular, the second with 

 a length three times its diameter, the third a little shorter than 

 the second and the fourth one-half longer and more slender than
