OBSERVATIONS ON SCALE-INSECTS (COCCIDAE) — III. 



371 



A very interesting and strikingly characteristic species. Closely related to 

 L. brunfelsia, Hempel,* and L. gracile, Hempel,f but distinguishable from both by the 

 presence of a well formed test, the arrangement of the dorsal plates and the antennal 

 formulae. 



Aspidiotus camelliae, Sign. 



Puparium of female. Larval pellicle blackish or piceous ; second pellicle rich 

 brown to piceous. Secretionary portion of puparium wdth a free admixture of fibres 

 from the food-plant. Form as in typical examples. Margin of pygidium (fig. 21, a, b) 

 with the squamae, especially those beyond the third pair of lobes, varying in a marked 

 degree in different individuals and presenting a distorted or malformed appearance ; 



Fig. 21. Aspidiotus ? camelliae, Sign., $ ; a, b, malformed 

 fringe of pygidium ; c, curiously truncated squamae. 



in two instances the structures were truncate (fig. 21, c) just above the origin of the 

 lateral processes, with a single or double ring of chitin at the extremity. In other 

 respects the females appear to be quite normal. 



The inconstancy of form and strikingly malformed appearance of the squamae is, I 

 think, due to disease, but certainly not to either fungi or insects, as no trace of such 

 parasites were found.

The branches submitted were heavily infested by this Coccid ; and about 80 per 

 cent, of the colony had been destroyed by a fimgus. The parasitised examples had
