54, Aciura xanthotricha, n. sp. $ . 

 (PI. X, fig. 55). 



Very like the preceding, but smaller and distinguished by the pale yellow pvt. 

 and superior occipital bristles ; and by the shorter ovipositor. Length of the body 

 3 mm., of the ovipositor 2 mm. 



This species is identical with the preceding in all the particulars of colour and 

 pattern of the wings. The pvt. are not longer than the other 4 pale yellowish 

 superior occipital bristles ; these 6 yellow bristles are similar in colour and thickness 

 to those which are characteristic of the section Trypaneininae, and are also obtuse 

 at the end ; the other bristles of the occipital row are black and thin. Arista with only 

 microscopic pubescence. The pale yellowish pile of the frons are more developed and 

 numerous, recalling those which are so developed in the American insecta, where they 

 also cover the thorax, which in the present species shows no trace of such hairs. The 

 ovipositor is distinctly shorter, broader and more flattened. Wing-pattern identical ; 

 the only difference which I can see is in the first indentations in the costal cell, which 

 in one specimen is much smaller but distinct, while in the other is entirely wanting. 



Two female specimens, both not well preserved, the type from Dhikata, Gharwal 

 Dist., W. Himalayas, U. P., 9-V-09 (^if^) ; the other from Tenasserim, Lower 

 Burma {W. Doherty) (iffi). 



Very striking is the difference in the postvertical and occipital bristles in these 

 two species, which are' almost identical in other particulars, 



3. Section Trypaneininae. 

 26. Tephrella, n. gen. 



Very like Aciura and bearing also only the basal pair of bristles on the scutellum, 

 but differing in the bristles of the occipital row being entirely pale yellowish and in the 

 thorax being clothed with pale pubescence. 



Head broader than high ; frons and epistome not prominent ; face a little con- 

 cave, with a light longitudinal keel in the middle ; cheeks rather broad ; eyes rounded ; 

 antennae inserted a httle over the middle of the eyes, the third joint i^ times as long 

 as the second, rounded at the tip, pubescent, not reaching the epistome, with bare 

 arista; proboscis short; palpi bristly ; oc. well developed ; or. 2. 3 ; genal bristle well 

 developed ; bristles of the occipital row well developed and entirely pale yellowish. 



Thorax with yellow pubescence and complete chaetotaxy ; pt. strong ; i mpl. 

 Scutellum with only the basal pair of bristles. Abdomen with the bristles less devel- 

 oped ; ovipositor flattened, long and narrow. Front femora with a row of bristles 

 beneath ; middle tibiae with a single spur ; hind tibiae almost bare. 



Wings narrow and elongate, with distinct costal bristle ; first vein short ; 2nd, 

 3rd and 4th straight, the third bare and parallel with the 4th ; cross-veins perpendicular, 

 close together ; the small one placed after the middle of the discal cell ; inferior angle 

 of the anal cell broad and pointed, but not drawn out into a point and shorter than
