208 PROF. M. BEZZI. 



the plumules tlim and straight. Vibrissae and lateral bristles of the mouth-border 

 but little developed ; palpi and proboscis black. Thorax black and very shining, 

 with distinct bluish reflexions on the back ; dorsal hairs very short ; chaetotaxy 

 normal ; mesopleurae with two anter or and three posterior bristles ; two strong 

 sternopleural bristles. Scutellum rather aeneous and faintly dusted, quite bare 

 except for the usual bristles ; squamuiae white and white-fringed ; halteres black. 

 Abdomen like the mesonotum, but without bluish reflexions ; ovipositor 1 mm. 

 long. Legs black, with the two basal joints of all the tarsi reddish yellow ; middle 

 femora with complete ciliation on hind border. Wings proportionally broad, quite 

 hyaline, with pale yellowish veins ; the terminal portions of the 2nd, 3rd and 4th 

 veins are straight, gradually and equally diverging, so that the third ends a little 

 before the tip of the wing ; small cross- vein before the middle of the discoidal cell ; 

 hind cross- vein straight, only a little longer than its distance from the end of the 

 fifth vein, sixth vein with spurious continuation to the hind border. 



Type $, a single specimen in Prof. Baker's collection from the Philippines, Baguio, 

 Benguet (C. F. Baker). 



7. Lonchaea (Carpolonchaea) bisulcata, sp. nov. 



A shining black species of proportionally greater size, with deep yellow wings ; 

 distinguished by the bisulcate frons of the female. 



$. Length of the body, 4 mm. ; of the wing, 4*2 mm. 



Frons proportionally narrow, a little less than twice as long as broad ; it is duUish 

 black, with sericeous reflexions and with shining black vertical plates ; in front of 

 the ocellar plate there is a rounded depression, from the sides of which emerge 

 two rather deep furrows, which converge towards the antennae, ending separately 

 at the upper border of the lunula. Antennae wanting in the type. Face black, 

 greyish-dusted, with rather shining antennal grooves ; cheeks linear ; jowls narrow ; 

 palpi and proboscis black ; chaetotaxy normal. Thorax shining black, with no dis- 

 tinct bluish reflexions ; chaetotaxy normal ; two equally strong sternopleural bristles. 

 Scutellum aeneous and faintly dusted, with numerous bristly hairs between the 

 usual bristles. Squamuiae yellow, with pale yellowish cilia ; halteres black. 

 Abdomen coloured and shining like the mesonotum, with black hairs and short 

 black bristles on the sides ; ventral membrane broad and reddish, ventral plates 

 shining black ; ovipositor short, as long as the last two abdominal segments together. 

 Legs entirely black ; middle femora with rather short but complete ciliation on 

 hind side. Wings yellowish, deeper yellow at base and on fore half ; veins yellowish, 

 but the costa appearing darker on account of its short black ciliation ; second costal 

 cell but little widened outwardly ; terminal portions of third and fourth veins parallel, 

 not diverging ; small cross- vein before the middle of the discoidal cell ; hind cross- 

 vein straight, about twice as long as its distance from the end of the fifth vein ; sixth 

 veiQ with spurious continuation. 



Type $, a single specimen in the writer's collection from South India, Trichinopoly, 

 1911 (F. Cajus); the chaetotaxy of the thorax and the black tarsi, in spite of the 

 want of the antennae, show that the species belongs to the subgenus Carpolonchaea. 



The present species may be the Indian Lonchaea without specific name figured by 

 Hewlett in Maxwell-Lefroy, Indian Insect Life, 1909, p. 636, fig. 420, from Pusa,
