foveae grayish-pollinose. Thorax with three faint grayish-pollinose 

 stripes; the middle one often hardly perceptible; the lateral ones, pla- 

 ced immediately above the dorso-pleural suture, have on the inner side, 

 an irregulär outline; pleurae grayish-pollinose and tomentose; scutellum 

 and methathorax likewise, but slightly. Abdomen with a short, delicate, 

 moderately dense, whitish pubescence. Halteres reddish. Front coxae 

 with a dense silvery-gray sericeousness; front legs brown, femora more 

 or less reddish above; similarly the other legs are brown, but the femora 

 more or less mixed with reddish. Wings almost hyaline; (Fig. 3) a 

 brown crossband runs across the two crossveins and is continued along 

 the Costa to the apex; between the stigma and the fourth vein there is 

 a large brownish-yellow spot, which, gradually attenuating, runs towards 

 the root of the wing. Two males and four females. 



Antineura sericata n. sp. $ Q. Metallic-green, thorax 

 ivitJi three golden-yellow sericeous stripes; femora yellow; length 

 8 — 15 mm. 



Front metallic-violet above the antennae, blue towards the vertex; 

 facial and frontal orbits golden-yellow; antennal grooves with a golden- 

 yellow bottom; between them the facial triangle brown. Antennae 

 reddish at base; third Joint brown; arista white, yellowish as base, 

 Occiput golden-yellowish sericeous below, with a golden-yellow down; 

 black above. Thorax with three golden-yellow, sericeous stripes;- the 

 intermediate one is a llttle eipanded before the scutellum; a similar 

 stripe crosses the pleurae and invades the mesosternum. Abdomen 

 with a delicate, short, not very dense golden-yellow pubescence; the 

 fourth segment is a little reddish at tip. Front coxae and all the fe- 

 mora yellow; tibiae brownish, tarsi brown. The pattern of the wings 

 is like that of the preceding species, only the brown crossband is less 

 dark; the costal margin (between the crossband and the apex) is yello- 

 wish-brown. — One male, two females. The specimens of this, as well 

 as of the preceding species vary very much in size. 



Philocompus. 



0. Sacken, Bull. Soc. Entom. Fr. 10. Aug. 1881. 



Philocompus differs from Antineura in its venation ; the fourth vein 

 is remarkably contorted ; the anterior crossvein is beyond the middle 

 of the wing, and hence unusually long; the posterior crossvein very 

 much curved. 



The structure of the body is so like that of Antineura that the 

 descriptioD of the latter need not be repeated. The differences which
