Head. The rostrum does not quite reach the trochanter. The first 
segment of the maxillary palpus is longer than the third, the second 
being a little shorter than the fourth. The subapical row of bristles of 
the occiput bears 5 or 6 bristles on each side. The first antennal 
segment of the </ is less produced posteriorly at the apex than in 
L. cheopis and nubicus; it bears 3 hairs at the hinder edge, and a 
transverse row of 5, proximally to which there are 2 more hairs. In 
the $ the projection of the first antennal segment bears one hair. 
Thorax. The nota of the thorax bear usually 12 bristles on both 
sides together, the pronotum having sometimes 14 and the metanotum 
occasionally 11. The sternite of the mesothorax bears 3 hairs. 
The episternum of the metathoi’ax has one bristle, while the epimerum 
bears an anterior row of 4 to 6 and a posterior row of 6. 
Abdomen. The irregular anterior row of the first tergite on both 
sides together contains 7 to 10 bristles and the posterior row 6. The 
second to fifth tergites bear in the $ 16 to 18 bristles on both sides 
taken together, the sixth 15 or 16, and the seventh 12, the </ having 
1 to 3 bristles less on the second to fifth tergites. The numbers of 
bristles on the sternites are as follows:—ii. 2, $ 2; iii. </ 4, $ 8 ; 
iv. J 1 5 or 6, $ 8 ; iv. to vi. J 1 5 or 6, $ 8; vii. 7, $ 6 to 8, the 
seventh segment bearing in $ some additional short bristles in front of 
the row. The dorsal subapical bristle of the seventh tergite is one- 
third shorter than the second hindtarsal segment, being very much 
shorter than in L. cheopis and nubicus, but agreeing with that of 
L. niloticus. 
Legs. The forecoxa bears about 24 bristles. The hindcoxa is 
rather strongly sinuate posteriorly before the apex, the angle behind 
the sinus being distinct. The hindcoxa, on the inside, bears a comb of 
6 to 9 spines, there being on the outer surface and along the anterior 
edge 22 to 24 bristles. The hindfemur bears a row of 5 to 7 bristles 
on the inside and 2 subapical bristles on the outside; the sub-basal 
ventral tooth of the femur is very distinct. The longest apical bristle 
of the hindtibia does not reach to the apex of the first hindtarsal 
segment. The first midtarsal segment is longer than the third, being 
two-thirds the length of the second. The longest apical bristle of the
