This coUection is of much interest as, apart from the new species which it contains, it was made 

 in regions which had hitherto been unworked by the Student of this remarkable and obscure group of insects. 

 In all it represents eleven diiferent species of which eight are new to science. Of the remarkable sabgenus 

 Selenaspidus there are two repräsentatives; besides which there are seven other genera, all of which have 

 hitherto been found in various parts of Africa. 



Aspidiolus {Chrysomphalus) aurantn Mask. is widely distributed in the tropical and subtropical zones, 

 and is generally a great pest of the various kinds of Citrus, as well as other cultivated plants. It has not 

 hitherto been recorded from the South- Western portion of the African continent though it is apparently 

 common in the south. The remaining species are probably precinctive; though they may at any time be 

 carried elsewhere on imported plants. 



I tender my thanks to Dr. L. Schultze, as also to the Directors of the Berlin Zoological Museum 

 for giving me the opportunity of investigating this material. At the same time I congratulate Dr. Schultze 

 on the discovery of so many new and interesting forms. 



Monophlehtis africanus n. sp. (Newstead). 



Female, early adult. Faintly farinose. Ovate, with a faint constriction at the thoracic area; low 

 convex above ; sides thick; segmentation marked. Colour (in alcohol) pale duU orange to dull orange 

 crimson ; legs and antennae black. A few pale hairs are visible at the margins, under a low power, otherwise 

 the integument appears smooth and glabrous. Under a higher magnification the derm is seen to bear 

 slender hairs, rather widely separated, but these are more numerous and longer on the venter than on the 

 dorsum ; between the hairs there are minute circular spinnerets (PL III, Figs. i, i a), some of which have a central 

 orifice shaped somewhat Uke a figure-of-8. Antennae (PI. III, Figs. 2, 2 a) normally of eleven segments but these 

 Organs are given to considerable Variation even in examples of the same stage and are also sometimes 

 asymmetrical. Eyes obconical, black. Legs short and stout; anterior tarsi (PI. III, Fig. 3) with a bilateral 

 row of 3 — 4 stout simple spines, ventrally ; anterior tibiae with 3 (possibly 6) very long spinöse hairs on 

 the Upper surface. The other legs are similar. 



Length 8 — 10 mm. 



Penultimate Stage of female. Of the same form and colour as the adult female. Antennal 

 segments varying in number from 7—9 ; the apical segment may be either pointed (rare) or broader (frequent) 

 and longer than the preceding one. 



Male. Pale orange crimson, in alcohol. Legs, sclerites (dorsal and ventral), and eyes black. Ab- 

 dominal lobes or tubercles on terminal segment two in number, these are nearly as long again as the width 

 of the preceding segment; each with 3 — 4 very long stout hairs. Margin of two preceding segments
