ON A NEW GENUS OF PSYLLIDH FROM NYASALAND. 
By Ropert NerewstTEap, M.Sc., A.L.S., &c. 
The remarkable insect herein described belongs to the family PsyLLip#, of 
which relatively few species have hitherto been recorded from Africa. ‘The 
pupx (and possibly also the larva) cover themselves with dense masses of white 
flocculent or wool-like wax, the separate strands of which are sometimes over one 
inch in length. These flocculent coverings are arranged together in large patches 
on both the leaves and stems of the food-plant so that they are thereby rendered 
most conspicuous. The habit of secreting coverings of white wax is common to 
many members of this family of the Homoptera; but the great length to which 
it attains in this species is quite exceptional and noteworthy. 
Pseudoeriopsylla, gen. n. 
Female :—Head with the frons twice as broad as long, front indentate or 
slightly cleft ; eyes hemispherical, prominent. Thorax with the pronotum equal 
in width to the frons, convex. Wings (fig. 13) broadly lanceolate, with a large 
stigma ; stem of sub-costal vein nearly as long as the upper branch of the 
cubitus ; radius of sub-costa short, and from it arises a very short supernumerary 
vein which merges into the costa near the middle. 
Pseudoeriopsylla nyase, sp. n. 
Female.——Colour of dried specimens pale ochreous buff; mesothorax with two 
bilateral, elongated and curved blotches of pale brown. Venter of abdomen 
covered with dense creamy white plates of wax. Antenne fulvous, tips infus- 
cated. Eyes black, with a faint margin of pale crimson. Legs ochreous buff ; 
tibial spines jet-black. Wings (elytra) (fig. 13) hyaline, broadly lanceolate, costa

more distinctly arched than the hind margin; stigma large, upper portions of 
the periphery black or infuscated ; stem of sub-costa infuscated just below its 
junction with the cubitus ; there is also a large infuscated area or blackish spot 
on the margin immediately behind the lower fork of the cubitus ; the tips 
of the succeeding veins on the hind margir are also infuscated and there are
