is hardly distinct from the last, the colour of the legs being 

 valuable.

 the eyes, dark-brown, almost black ; third joint of the antennae 

 nearly black. Thorax with yellowish-brown tonientmn and 

 scattered black bristles. Halteres pale-yellow. Wings yel- 

 lowish, the veins near the base yellow; in the centre and 

 posterior they are dark-brown. Legs and lower surface of

Anabarhynchus nebulosus, sp. nov. 



Male. — Brown, with short white hairs all over the body. 

 Short black hairs on the occiput, brown hairs on the vertex ; 

 hypostoma without hairs. Thorax with five indistinct, longi- 

 tudinal, darker bands. Halteres yellow. Wings clear, with 

 dusky clouds in the centres of the cells, except the first sub- 

 marginal, in which the cloud is near the tip. Legs dusky, 

 except the tibiae, which are yellow. Length, 9 mm. ; wing, 

 8 mm.

I have not seen the female. 



Section B. 



Abdomen linear, reddish-brown. Length of the first joint 

 of the antennae more than twice its breadth ; the second sub- 

 globular ; the third not longer than the first, oval or linear, 

 hairy at the base. 



The species of this section have the third joint of the 

 antennae hairy, as in Xestomyza, but the shape of the antennae 

 is different, and the anterior legs are not elongated. 



Anabarhynchus castaneus, sp. nov. 



Chestnut-brown, the face and thorax with golden to- 

 mentum, which is denser on the scutellum and on two bands 

 on the mesonotum. The first six segments of the abdomen 

 fuscous posteriorly on the dorsum ; under-surface and legs 

 castaneous. Hairs on the front and antennae black, those on 

 the lower surface of the head white. Abdomen linear-conical, 

 almost naked. Wings yellowish, the veins fuscous; no stigma, 

 but a dusky cloud in the middle of the marginal cell, with a 

 clear space inside it; another dusky cloud in the first posterior 

 cell, close to its base ; sometimes another in the base of the 

 second submarginal and centre of the first posterior cells. 

 Hypostoma with white hairs. Length, 12 mm.; wing, 10mm.
