HOST PLANTS. 



Apocynacese *Nerium oleander. 



Leguminosse Bauhinia sp. 



Myrtaceae Psidium guajava (Guava). 



Rosacese Prunus domestica (Plum). 



PART OF PLANT ATTACKED. 

 Young stems. 



REMARKS. 



This species is not very common in Egypt but is apparently 

 widely distributed. 



Subfamily DIASPIN^E. 



27. Adiscodiaspis tamaricicola Malenotti. 



BIBLIOGRAPHY : Rediaxi, 1915-1916, pp. 313-315. 



The puparium of the adult female is very strongly convex, ovate, 

 highest convexity being in the cephalic area ; colour greyish white. 

 The pellicles are eccentric, but within the margin ; the first pellicle 

 is generally obliquely placed, sometimes transversely placed, on 

 the second pellicle. The pellicles are straw coloured, but are not 

 very apparent, being covered with a coating of greyish white secre- 

 tionary matter giving them the same appearance as the rest of the 

 puparium. 



The adult female is oval and brownish yellow. 



Length of female puparium 1-5 millimetres. 



This is a species of a very interesting genus. The usual pygidial 

 characters of the DIASPIN^E are entirely absent. There are no squames, 

 hairs, or lobes, unless the slight corrugations of the pygidium can be 

 called lobes, and if so they are very broad and flat. Circumgenital 

 glands are also wanting. The genital aperture is very well developed.

 The small branches. 



REMARKS. 



This is a comparatively rare species. It was first described by 

 Malenotti (loc. cit.) from specimens on Tamarix sp. collected at Matariya 

 (Egypt) and given to Prof. Paoli by Mr. Willcocks.
