Enicoptera proditrix n. sp, $ $. — 



Is very like E. flava Macq. D. E. Suppl. 3. 63, Tab. 7, f. 9, 

 but diiFers principally in having a black median thoracic stripe, besides 

 the two lateral ones; the abdomen has two longitudinal black stripes; 

 the hind femora are more or less infuscated. 



Head browuish-yellow; in the male, the third antennal joint is 

 more brown and there is a brown spot in the middle of the face, and 

 another on each side of the frontal lunule; (these characters are wan- 

 ting in my four females specimens). Thorax yellov^^, with three black 

 stripes; the lateral ones interrupted at the suture; humeral callus and 

 an indistinct stripe between it and the root of the wing, brownish; a 

 similar stripe across the pleura, between the humerus and the front 

 coxa, the brown extending to the latter; and another between the root 

 of the wing and the hind coxae; these two stripes on the pleurae are 

 almost evanescent in the female, but very distinct in the male; scu- 

 tellum with a round black spot on the apex; metanotum brown. Ab- 

 domen yellow, with two broad lateral brown stripes, which begin in 

 the middle of the first segment, where they are sometimes connected 

 by a crossband; in the male that crossband fills the whole distal 

 half of the first segment, and the longitudinal stripes are so broad that 

 they reach the lateral margins of the segments; halteres reddish with 

 a brown knob; legs brownish-yellow, hind femora more or less brown; 

 in the male, the front and middle femora also have a dark brown spot 

 on the posterior side before the tip. Wings like Macq. 1. c. Tab. 7, 

 fig. 9 ; only the brown of the costa fully fills the space between it and 

 the third vein. In the male, the large, oblique crossband coalesces 

 with the brown cloud on the posterior crossvein, and then follows the 

 elongation of the anal cell, and thus joins the brown at the base of 

 the wing. In the female the cloud on the posterior crossvein is sepa- 

 rated from the great oblique crossband by a broad hyaline interval, 

 but connected with it at its anterior end by a yellowish prolongation 

 running towards the anterior crossvein. Length $ 11 — 12 mm.; $ 

 10 — 15 mm. (without the ovi positor). — One male, four females. 



Diopsidae. 



I have five species from the Philippine Islands before me, which 

 may be tabulated thus : 



Alulae distinct; sixth vein distinctly pro- 

 longed beyond the anal cell. Genus 

 Sphyracephala Say 1. cothurnataBigot. 



Alulae obsolete; sixth vein not prolonged 

 beyond the anal cell.
