656 ASILiD^ 



very conspicuous tawny pubescence, and in the larger oval enclosure the 

 broad flat oblong middle piece arises and bears only short slight pubescence ; 

 lower lamellge rather small, broad at the base, but quickly narrowing to a 

 point and curving up between the claspers and bearing moderate black 

 pubescence ; there is no basal plate and apparently no eighth abdominal 

 segment. 



Legs black and orange, the tibiae being bright orange except for the 

 rather sharply defined black tip ; tarsi orange on all the basal joint, on more 

 than half the second joint, and on less than half the third joint, while the 

 last two joints are brown at the base. Pubescence comparatively slight ; all 

 the coxae grey, and the front pair with dense long greyish yellow pubescence in 

 front, the middle pair with similar pubescence on the apical half in front, 

 and the hind pair with a little long straggling pubescence ; front femora 

 with fairly abundant black pubescence beneath (rigid and rather dense near 

 the base) and rather scarce very thin haired orange pubescence behind ; 

 middle femora with moderate black pubescence beneath on the basal half ; 

 hind femora in all the English specimens I have seen with only short 

 pale pubescence behind, but with a little' longer pale pubescence in continental 

 specimens ; front tibiae with a few long orange hairs beneath. Bristles 

 usually all black ; none on the front femora unless one postero-ventral one 

 near the tip be strong enough to notice ; front tibiae with six dorsal bristles 

 extending over the whole length, six postero-dorsal (the one near the base 

 strong), and three or four thin (almost hair-like) postero-ventral, and with 

 the usual terminal circlet ; front tarsi with the usual bristles ; middle coxas 

 with usually one strong black bristle in front and often several about the tip ; 

 middle femora with about eight rather crowded bristles in front, about five 

 antero-ventral, one slightly postero-dorsal just after the middle, and about 

 two postero-dorsal near the tip ; middle tibiae with about five postero-dorsal 

 bristles in a row (four near the middle and one nearer the tip), about five 

 rather irregular postero-ventral, and about two almost ventral after the 

 middle, and the terminal circlet and tarsal bristles as usual ; hind trochanters 

 with about four bristles which are inconspicuous when orange but conspicuous 

 when black ; hind femora with about seven small anterior bristles extending 

 over nearly the whole length, about ten antero-ventral, and about ten small 

 postero-ventral ; hind tibiae with about four (4-7) slightly postero-dorsal bristles, 

 one slightly antero-dorsal near the base and another at about three-quarters 

 the length, two antero-dorsal near the middle but wide apart (and sometimes 

 three of which the lower two are after the middle), two or three antero-ventral 

 of which the upper one is near the middle, three (3-4) very small ventral of 

 which one is after the middle and tlie other two (or three) near the tip ; 

 hind tarsi with the usual bristles but with a few of the anterior bristles 

 of the terminal circlets sometimes orange. Pulvilli broad oblong, dull orange ; 

 empodium represented by an orange bristle which is much shorter than the 

 pulvilli. Claws black but brown at the base, hardly curved on the basal half. 



Wings milky white at the base or at least on the whole of the axillary cell 

 and alula, but with rather more than the outer half blackish brown, and 

 the two colours separated almost straight across the wing, but in immature 

 specimens the contrast is not so great as the base is less milky and the tip 

 less darkened ; mediastinal and subcostal veins and often the stem of the 

 postical yellowish, but the other veins blackish, though the hindmarginal 

 ambient vein is white ; upper branch of the cubital fork only slightly upturned 

 at its end ; alula and its mai-ginal vein white and with only a minute fringe. 

 S(iuamae (alar) dull orange, with thick orange margins on which is an 

 abundant rather long dull orange fringe except near the alar end ; thoracal 

 pair only represented by a bare orange membrane. Halteres orange. 



? . Very much like the male. Abdomen with the tawny pubescence more 

 extended and more conspicuous, and with large triangular yellowish grey hind 

 corners to the segments ; seventh segment but little shorter than the sixth ; 

 eighth segment concealed ; ovipositor not in the least compressed, about as 

 long as the sixth abdominal segment, with its basal part shining black above 

 but below with an equally large greyish black ventral plate ( = eighth ventral 

 segment?), and after that with two or three short joints and a short blunt
