joint of hind tarsus a little longer than 2nd and 3rd uni- 

 ted; 3rd a little shorter than 2nd; 4th one and a half ti- 

 mes shorter than 1st. Third anal vein present in the 

 fore wing. 



Type: Bittacus blanchetl Pietet. 



Ksilobittacus gen. nov. 



In the fore wing first anal vein is very short, hardly 

 half as long as posterior branch of cubitus. Second anal 

 vein likewise short, two thirds of the length of first anal 

 vein. Third anal vein not present. In the hind wing 

 first anal vein coalesces with posterior branch of cubitus 

 for its whole length, and it joins the hind margin a little 

 beyond the place, where media and anterior branch of 

 cubitus separate. Second anal vein short, one third of 

 the length of first anal vein. Third anal vein not pre- 

 sent. Eyes as far apart in front as the breadth of rostrum 

 at base. Basal joint of hind tarsus a little longer than 

 2nd and 3rd united, which are equal; 4th two thirds of 

 1st; 5th a little longer than 3rd. 



Type: K- bimaciilatus sp. nov. 



At first sight this genus is quite similar to Bittacus; 

 but the coalescence of posterior branch of cubitus and 

 first anal vein in the hind wing is a good generic cha- 

 racter, only present in Kalobittacus and Paz'ms. From 

 the latter it may easily be separated by the broad basal 

 part of the wings and by the larger distance between 

 the eyes. 



K' bimaculatus sp. nov. 

 Head, rostrum and maxillary palpi yellowish brown. 

 On the vertex a black spot, enclosing the ocelli. Antennae 

 yellowish brown; the two basal joints stout; 2nd joint as 

 stout as 1st, globular. Thorax and abdomen brown. Legs 

 brown; tip of femora, tibiae and of tarsal joints brownish 

 black; hind femora rather stout, incrassate in the middle.
