accompanied by European friends,* and that the present Eajah, 

 Sir Charles Brooke, did the same. Only a few remembered the 

 Chinese rebellion in Sarawak, which took place in 1857, and 

 recollections of that great event seem to have swamped all 

 memories of events before it ; so that Wallace's visit in January, 

 1856, must now be relegated to that great host of events which 

 took place in the irreclaimable past no longer within the memory 

 of man.

3. 0. annulipes, Mg. — Proboscis with a rather ill-defined pale 

 band in the middle. Head scales yellowish. Scales of meso- 

 notum dark brown in the middle, rather bright yellow at the 

 sides. Segments of abdomen with yellowish basal bands, 

 covering nearly half of each of the segments 3-5, but narrower 

 on the remaining segments ; apical portion of segments mainly 

 dark brown, but with scattered pale scales. Wings and legs 

 speckled with light and dark scales, but femora nearly all yellow 

 behind. 0. annulipes is very much like O. maculatus in general 

 appearance, but can be distinguished in the female sex without 

 much difficulty by the characters given in the key. The males 

 are more easily separated by the structure of the genitalia. 

 Eough figures of the genitalia of both the species are given. In 

 0. annulipes (fig. 1) the harpes (basal appendages) are long and 

 strap-shaped, and in 0. maculatus (fig. 2) they are shorter, and 

 provided with a large membranous expansion near the tip. 

 Average length, 7-8 mm. 



The British Museum possesses specimens from Angmering, 

 Sussex {Rev. A. E. Eaton) ; Longner Hall, Shrewsbury {R. F. L. 

 Burton) ; and Rollesby, Norfolk {G.H. Verrall). 



I have no doubt that this species is correctly named, as it answers 

 quite well to Meigen's description. Ficalbi, however, states that the 



* Sir Spenser St. John visited the place in 1851-2, spending some months 

 there in all (see his ' Life in the Forests of the Far East,' 2ud ed. 1863, vol. i. 

 pp. 162-169). Ida Pfeiffer visited the Dayak villages on Serambu in Decem- 

 ber, 1851 (see her account of it in ' A Lady's Second Journey round the 

 World,' 1856, pp. 50-55). The distinguished botanist, 0. Beccari, spent a 

 week there in 1865 (see his ' Wanderings in the Great Forests of Borneo,' 

 1904, pp. 54-60).
