Material in very poor condition, the puparia being for the most part destroyed 
by a predatory insect of some kind possibly a coccinellid larva though no examples 
were submitted. Associated with these was a single female, of Aspidiotus trilobiti- 
formis Green. 
Togo, XI. 1904, auf Sarcocephalus sambucinus (Winterbolt) K. Sch. Var., Dr. Busse. 
The puparia practically covered the leaves of the food-plant. 
Yab, West Karolinen, Sander 8. G. 
Three leaves of Calophyllum inophyllum were partiy covered with the remains 
of the female puparia; all, however, in very poor condition, and in most cases 
nothing but traces of the ventral pellicle left. The only fassible interpretation 
possible is that the puparia had been destroyed by some predaceeus insect and 
possibly a coceinellid larva. A few larvae of a species of Dactylopius (Pseudococeus sp.) 
ware also associated with the Diaspids. 
Yap, West Karolinen, Sander G. „Bericht vom 7. Juni 1903, Nr. 250.* 
The leaves (? Cocos) submitted were practically covered with the puparia of 
this common and widely distributed coceid. 
Aspidiotus hederae (Vall.) (= A. nerii Bouche.). 
Habitat: D. Ost-Afrika, Dar es Salaam, April 1902. Auf Nerium oleander. 
Prof. A. Zimmermann N. (Nr. 10). 
The leaves of the food plant (Nerium oleander) were completely covered with the 
puparia of the young adult females together with a number of those of the male also. 
Aspidiotus (Chrysomphalus) aurantii Maskell. 
Attacked by a remarkable fungus (Microcera sp.) which is certainly primary and 
not secondary. 
I have met with the same fungus attacking various species of African Diaspinae 
(Ischnaspis filiformis, Doug. and Aspidiotus spp.) In the first instance, now several 
years ago, whole colonies of coccids infesting coffee in British Central Africa were 
destroyed by this fungus, the hyphae of which had penetrated every portion of the 
insect, replacing all its tissues as well as its secretionary covering. It may be easily 
recognised when fresh, by its pale orange-erimson colour and the curious tassel-like 
growths beyond the margin of the scale. It undoubtedly keeps down these insects 
and may eventually prove of great benefit in checking the spread of these pests.

Several examples of both d and 9 puparia, the latter chiefly immature:

The male puparia of a species of Chionaspis and also examples of Mytilaspis 
citricola were associated with these specimens.
