 beyond the base of /?2 ; basal section of 1^4,^5 oblique ; Ouii, 

 well before middle of discal cell. \

This species is of interest, since it obviously connects 

 L. marshalli with L. cyatheti. The venation, except for the 

 position of Cuia, is practically as in the latter species, and 

 the relationship is also shown by the coloration of the 

 antennae. 



Gynoplistia orophila, sp. n. 



^ . Head black, somewhat shining, but very distinctly 

 dusted over with grey. Front broad, slightly broader than 

 one eye. Antennce black, 16-segmented, last five segments 

 simple, the appendages of the intermediate segments about 

 six times as long as the segments. Palpi black. Thorax 

 shining black, the pronotum, the front of the prsescutum, and 

 the posterior lateral corners of the scutum reddish. Pleura 

 with some rather inconspicuous grey hair. Abdomen shining- 

 black, the hypopygium bright orange. Ninth tergite with 

 a rather long median projection, provided with a small tooth 

 on each side at the base. Side-pieces with a rather long 

 ventro-basal thumb and a broad ventro-apical plate-like 

 expansion, and on the inner face with some rather dense 

 orange hair. Inner clasper with the broad tip bent and 

 twisted. Parameres bifid, the longer branch reaching tip of 

 side-piece. Legs black ; coxse, trochanters, and about the 

 basal halves of the femora orange. Hind femora rather 

 strongly clubbed. Tibial spurs normal. Wings much re- 

 sembling G. 7iigronitidaf Edw.,- in venation and pattern, but 

 the spot at the base of the basal cells is only faintly indicated, 

 while the wing-tip is much more conspicuously darkened. 

 Halteres with ochreous stem and black knob. 



$. Antennge 16-segmented; the ventral enlargement of 

 the first eight flagellar segments about equal in length to the 

 diameter of the segment. Prajscutum, scutum, and scutellum 

 maiidy reddish, also the sternopleura. Femora rather more 

 extensively orange; tibiae brownish, with black tips; tarsi 

 largely brown. Otherwise as in the male. 



Length of body, (j" 6, $ 8*5 mm.; wing, (^ 7, $ 8 mm.
