tlie sides ; the abdomen is conico-eylindrical, Tcry glabrous, and has all the setse 

 large, and those on the fourth segment very numerous ; the wings have the fourth 

 longitudinal vein bent at rather a rounded angle, and the outer cross vein a little 

 curved, but not usually sinuous ; the legs are black, and armed with numerous 

 strong spines irregularly arranged. Not common. 



20.— EPICAMPOCERA, Mcq. 

 Gen. ch. — Eyes hairy, nearer together in the males than in the 

 females ; palpi projecting and a little elavate, forehead very slightly 

 prominent ; epistome flat ; cheeks minutely ciliated ; facialia almost 

 bare ; antennae with the second joint short, the third three or four 

 times as long, thick, with the front surface convex, and the end 

 rounded ; abdomen oval, with the segments armed with setse both on 

 the disc and edges. 



E. succiNCTA, Mgn. 

 Blue-black, with black palpi, antennae, and legs ; frontal stripe brown ; sides of 

 frontalia bluish ; face white, with blue reflections ; fronto-orbital bristles extending 

 down one-fourth of the length of the face, four being placed below the base of the 

 antennae ; arista long, thickened for about two-thirds of its length, and minutely 

 pubescent ; thorax indistinctly striped witli four slender lines ; scutellum black ; 

 abdomen glabrous, with white reflections, which assume the form of irregular trans- 

 verse bands when viewed from behind ; wings with the apical cross veins nearly 

 straight, and the outer cross veins a little sinuous at the base. Not uncommon. 



21.— EXORISTA, Mgn. 



Gen. ch. — Species mostly of moderate size and oval shape; eyes 

 hairy, rather widely separated in both sexes, and prolonged down the 

 sides of the face ; forehead mostly short ; antennae with the second 

 joint rather short, and the third from twice to six times as long ; front 

 surface of the latter straight, or nearly so ; arista with the second 

 joint often a little elongated ; cheeks bare ;* facialia unarmed, or only 

 ciliated with short weak bristles along their lower halves ; abdomen 

 sometimes with and sometimes without discal setse on the middle seg- 

 ments ; wings with the fourth longitudinal vein with an angular bend, 

 and the first posterior cell partly open, and terminating a little before 

 the tip of the wing. 



The species are very numerous ; almost all those that I have ex- 

 amined have four external dorso-central thoracic bristles behind the 

 transverse suture, so I shall only mention them when they vary from 

 that number ; most of them also have the thorax and abdomen very 

 similarly coloured and marked, so that the specific characters must be 

 taken chiefly from differences in the colour of the palpi, scutellum, 



* Sometimes the fronto orbital bristles extend down the face, but they arc never ciliated with 

 fine hairs as in the preceding genus.
