as given on page 162 of the " Injurious and Beneficial Insects of 

 California " 1915. On examination, however, I found that there 

 were two distinct species and that neither was a Chionaspis. Mr. Laing 

 has kindly identified them for me as L. affinis Leon and L. pusilla 

 Low. I give figures of the pygidia of both these species. 



L. ajfinis Leon is common in Egypt wherever pines are found. 



SI. Leucaspis pusilla Low. (Fio. 4). 



BIBLIOGRAPHY : Loew., Wien. Ent. Zeit., ii, p. 3 (1883). 



Female puparium white, convex, shaped like a spear head, widest 

 about one-third of the total length from the posterior extremity. 

 First pellicle yellow to brown, second pellicle forming the female 

 puparium, greyish white, very highly chilinized and covered with 

 white secretionary matter. Considerable difficulty was experienced 

 in removing without damage the adult female from its chitinous 

 puparium. 



Length 1-1-5 millimetres. Breadth 0-5-0-75 millimetre. 



Male puparium white, narrow, not dilated as the female puparium, 

 being slightly wider only at the posterior extremity. Pellicle pale 

 yellow. 



Length 1 millimetre. 



HOST PLANTS. 



Coniferae Pinws sp. (Pine). 



PART OF PLANT ATTACKED. 

 The pine needles. 



REMARKS. 



This species is common on pines in Egypt. (See the remarks 

 on this species under L. affinis Leon.) 



52. Leucaspis riccas Targ. 



Puparium of adult female elongate, usually straight, but crowded 

 examples sometimes curved, sides approximately parallel. The 

 second pellicle, constituting the puparium, is highly chitinized and 

 shining brown red ; it is covered by a thin layer of whitish secretionary 

 matter, the resulting appearance of the puparium being grey to a slate 

 grey. The first pellicle is pale yellowish green.
