6 SJÖSTEDTS KILIMANDJARO-MEHU EXPEDITION. 12: l. 



surrounding them are a few spinöse hairs and circular spinnerets. (^land tracts occur 

 on the derm beneath all the patches of secretion, these are irregulär in outline, and 

 so dense that no orifices are visible in them. Derm, dorsally and ventrally, practi- 

 cally covered with long slender spines interspersed with large circular spinnerets (Fig. 4). 

 Mentum monomerous, rather long, furnished with numerous spinöse hairs, some of 

 which are of great length. 



Length 5,50 — 8 mm.; greatest width 3,75—5 mm. 



Young adult f emale without patches of white secretion ; ovate but only slightly 

 narrowed in front, low convex; colour dark terra-cotta red, base of abdominal arti- 

 culations, and large thoracic punctures darker; legs and antennae piceous, tibiae and 

 tarsi paler. Antennae, legs and derm as in old adult. Length as in the adult. 



Female (? second stage). Dull orange yellow; tumid. Antennae of eleven Seg- 

 ments, similar in character to those of the adult female, but the segments are not 

 so highly chitinised. Mentum monomerous. Derm covered with long slender spines. 

 Legs normal; lanceolate spines of tlie tibiae and tarsi as in adult female. Length 

 3,60 mm. 



Larva (Fig. 5) very elongate. Antennae (Fig. 6) of five segments; the first 

 broad, conical; the second and fourth shortest, together about equal in length to the 

 third; the fifth much the longest, claviform, with two long and several short slender 

 hairs. Marginal bristles: anal Segment with 3 pairs of which the second pair are 

 much the longest; laterals 10 — 11 in number, those immediately succeeding the long 

 caudal ones short, the rest gradually lengthening towards the cephalothoracic area; 

 there are also two between the antennae, in front. Dorsum with many long slender 

 spines. Anal ring nonsetiferous. Mentum monomerous, obtuse, with many fine hairs 

 at the apex. 



Kilimandjaro : Kibonoto. December 1905. Among grass especially in scrub. 

 Many females. The larvae were taken from the boclies of their parents. 



The distinguishing features of this insect are its relatively small size, the short, 

 flat, patches of white wax, the curiously shaped spines to the tarsi, and the three 

 chitinous rings to the abdomen.

Fig. D, 1 — 5. — Female adult (Fig. 1) ovate, widest posteriorly ; highly convex, 

 sides thick, rounded or sub-vertical ; covered with a thin layer of fine granulär greyish- 

 white secretion, with the exception of a median-dorsal and submarginal tract which 

 appear as distinct blackish bands and show up in marked contrast to the other por- 

 tions of the insect ; the median band is usually interrupted in the region of the anal 

 orifice (subcentral); and the continuous marginal band generally narrows towards the 

 posterior extremity; the dorsal surface is also densely and uniformly spinöse. Venter 

 and legs piceous or purplish black, the former farinose ; margin with a narrow inter- 

 rupted line of denser white secretion.
