Li:CANIUM LONQULUM, Douglas, PARASITIZED BY LECANIOBIUS 



COCKEEELLII, Ashmead. SECONDARY PARASITE, 



HOLCOPELTE, n. sp., Ashm.

Scale. 

 The presence of a parasite is readily determined by the external 

 appearance of an infested scale. JNormal dried np scales are less 

 plentiful in nature, since they readily detach from the bark, and. are 

 shaken off by the swaying of a bough or blown away by wind ; they are 

 fairly translucent, of a dull fuscous colour, and without any prominent 

 character to denote their condition— whereas infested scales are some- 

 what transparent, of a slightly lustrous brown, and bear round their 

 base at the angle formed with the margin an apparently continuous 

 black fascia ; they are hard, brittle, and their margin adheres most 

 tenaciously to the bark — due evidently to the adhesive property of 

 the insects' body juices which accumulate at the base. The point of 

 emergence of the parasite is usually sub-apical cephalod. 



Primauy parasite. 



Lecaniohius CoclcerelU, Ashm. — This parasite is also recorded as 

 infesting L. hegonice, Dougl.* Although I have carefully examined 

 several hundred parasitized scales I have been unable except in two 

 instances to discover the primary parasite, but in a third I found a 

 larva which was subsequently reared, and proved to be the same insect. 



In one instance, only the head of a chrysalid was discernible, 

 while under or within the same scale was a pupa of the secondary 

 parasite referred to below. In the other I found a living pupa, which 

 lay loosely within the scale, its position being identical with the latter. 

 I may add that I have reared the same parasite from Ceroplastes 

 roseatus, Townsend and Cockerell (Journal N. T. Ent. Soc, Sept., 

 1898, p. 176).
