Genus Holorusia Loew. 

 Holorusia flavicornis sp. n. (PI. XV, fig. 2). 



Antennae of $ elongate, without bristles; thoracic dorsum rich 

 chestnut; pleurae yellow above, paler beneath, a dark lateral stripe; 

 wings pale brown. 



Male. Length, 13.2 mm.; wing, 19.3 mm.; antennae, about 7.5 mm. 

 Fore leg, femur, 10.8 mm.; tibia, 12.3 mm.; tarsus, segment I, 21.4 

 mm. 



Palpi rather short, dark brownish black, the frontal prolongation of 

 the head rather long, the nasus very long and sharply pointed, the 

 prolongation is brown, rather darker on the sides ; antennas elongate, 

 scapal segments very small, the first only a little longer than the 

 second, the flagellar segments elongate cylindrical, not incised, with- 

 out bristles but densely clothed with very short pale hairs ; antennae 

 light yellow, the apical flagellar segments a little darker ; head with a 

 light brown median stripe, the sides behind the eyes rich chestnut 

 brown. 



Pronotum rich chestnut medially, light yellow on the sides, this 

 color being the anterior end of a broad pale stripe underneath the 

 mesonotal praescutum. Mesonotal praescutum rich chestnut brown, 

 stripes not very distinct, the lateral margins of the sclerite rather 

 darker ; scutum dark brown ; scutellum brown ; postnotum dark brown 

 in front, light dull yellow behind. Pleurae rather pale ; a yel- 

 low stripe, described above, running from the pronotum almost to 

 the wing root; ventrad of this, a dark brown stripe running from the

 droplets in cell istRi, end of RS, Ml, base of M2 and tip of istA near 

 the vein 2nd A. Venation, see Plate XV, figure 2. The wing figured 

 shows an adventitious crossvein in cell R$ dividing this into two 

 cells the other wing being normal. 



Abdominal tergites brown, the genitalia more yellowish, sternites 

 a little more yellowish. Hypopygium small, 8th tergite rather narrow, 

 especially medially ; 8th sternite rather short, produced caudad into a 

 very short sheath for the gth sternite. Ninth tergite rather square, 

 the caudal margin deeply concave, the latero-caudal angles produced 

 into prominent lobes which are somewhat divergent, the tips and cau- 

 dal margin provided with numerous black bristles. Ninth sternite 

 rather large, pleura not distinct, near the base of the sclerite on the
