about 10 to 12 bristles according to Enderlein, there being an additional 
row on the first abdominal tergite. The sternites of the third to seventh 
abdominal segments have each a row of about 6 to 8 bristles. The 
rostrum is longer than the maxillary palpus. 
The insect is apparently closely allied to L. cheopis.

The specimen which we originally described as the $ of nubieus now 
appears to us to belong to cheopis. There are no specimens among our 
material which with safety can be regarded as the $ $ of L. nubieus. 
The J is easily distinguished from L. cheopis by the genitalia. The 
clasper (PI. IV, fig. 6) bears two slender processes, the shorter process 
having 3 to 5 bristles at the apex, of which the one occupying the tip 
is the longest. On the dorsal side there is another pair of hairs, placed 
at two-thirds or three-fourths the distance from the base. The hori¬ 
zontal portion of the ninth sternite (ix. st.) is transparent, being very 
slightly chitinized, except its ventral margin and base. Along the 
ventral margin there are from 10 to 13 hairs. The internal plate of 
the penis (Pen.-Pl.) is broad, its apex being rounded, with the upper 
corner slightly angulate.

is broader, the first midtarsal segment a little longer and the tooth of 
the hindfemur rather more strongly developed. The genitalia are
