REPORT OF THE STATE ENTOMOLOGIST I<jl6 21 7 



Male. Length 2 mm. Antennae dark brown; 14 segments, 

 the fifth with a length about one-half greater than its diameter; 



terminal segment narrowly oval. Palpus; one short, stout segment, 

 dilated apically. Mesonoinm dark brown. Scutellum dark brown, 

 slightly yellowish apically, rather thickly clothed with golden 

 yellow hairs, postscutellum dark brown. Abdomen a dark purplish 

 brown, badly nibbed and the markings, therefore, indistinct. Wings 

 (pi. 6, fig. 3) hyaline, costa with dark brown scales, the third vein 

 joining the margin just before the distal third; halteres pale yellowish 

 basally, slightly fuscous apically. Coxae fuscous yellowish, laterally 

 with irregular patches of silvery white scales; distal portion of femora, 

 tibiae and tarsi a nearly uniform purplish brown, the base of the 

 second and the third tarsal segments on most of the legs deep crimson. 

 Genitalia; basal clasp segment long, stout; terminal clasp segment 

 greatly swollen at the base; dorsal plate long, broad, deeply and 

 narrowly incised; ventral plate short, broadly rounded. Harpes 

 short, stout, irregular. Type Cecid. an67. 



Female. Length 2 mm. Antennae dark brown, yellowish basally; 

 17 segments, the fifth with a length a little greater than its diameter, 

 the two distal segments fused, the latter about twice the length of 

 the former. Palpus; one segment. Face fuscous yellowish, with 

 patches of silvery white scales. Mesonotum dark brown, thickly 

 clothed along the antero-lateral margin with golden yellow hairs, 

 submedian lines broad, thickly clothed with golden yellow hairs. 

 Scutellum dark brown, slightly yellowish apically, rather thickly 

 clothed with golden yellow hairs, postscutellum dark brown. Abdo- 

 men dark purplish brown, the first and second segments margined 

 posteriorly with reddish orange, the third, fourth and fifth segments 

 narrowly margined posteriorly on each side of a broad lateral line 

 with silvery white scales; sixth segment with dorsal sclerites small, 

 dark brown, margined laterally and posteriorly with silvery white. 

 Ovipositor fuscous yellowish or pale orange, pleurae and venter 

 suffused with silvery white scales. Wings hyaline, costa purplish 

 brown, discal spot yellowish white, the third vein at the distal 

 third (pi. 6, fig. 2); halteres pale yellowish basally, slightly fuscous 

 apically. Coxae fuscous yellowish laterally with irregular patches 

 of silvery scales, distal portion of femora, tibiae and tarsi a nearly 

 uniform purplish brown; claws heavy, strongly curved distally, 

 the pulvilli a little longer than the claws. Ovipositor moderately 

 long, the terminal lobes broadly orbicular. 



Another female bred from the same material differs in that the 

 basal antennal segments and face are fuscous, while the markings 

 on the posterior portion of the head and mesonotum are much less 

 pronounced ; the base of the second and third tarsal segments on most 

 of the legs is a deep crimson, otherwise about as described above. 

 Cecid. an67.
