B. W. Griffith, California, in the ' Los Angeles Times' 

 of 2nd July, 1893, and subsequently by Mr. Alexander 

 Craw in a ' Bulletin of the Calif ornian State Board of 

 Agriculture.' I have only seen Mr. C. L. Marlatt's 

 account of the male in his valuable work on ' The Scale 

 Insect and Mite Enemies of Citrus Trees/ in which the 

 author gives an excellent figure of the male and the 

 pupa. I am indebted to him for the above information. 



Ova yellowish. 



Larva reddish-pink. 



Habitat (under glass). First recorded by Curtis in 

 1843 on Brexia spinosa, a native of Madagascar. In 

 1887 Douglas recorded it on Brexia madagascariensis 

 and Crat&gus gynandra, from the Royal Botanic 

 Gardens, Kew, where it still exists, and affects the 

 following plants : Aralia elegantissima, *Croton elu- 

 teria, *Avicenia nitida, * Eldeodendron orientale, 

 *Carissa spinarum, *Catesbdsa spinosa, Spathelia sim- 

 plex, Thyrsacanthus rntilans, Miconia magnifica, Leuca- 

 dendron argenteum, Glavija minor., and Encephalartos 

 spp. Mr. Green records it from Yalding, Kent ; and 

 Dr. D. Sharp has sent it to me from Cambridge. But 

 it does not appear to be widely or generally distributed 

 as a greenhouse pest in this country. 



Habits. The females are almost universally par- 

 thenogenetic. Dr. B. "W. Griffith, California, was the 

 first to discover the male of this species ; he found the 

 puparia on oleander, orange, lemon, pepper, and ivy 

 leaves, between the months of November and April, 

 in the Los Angeles country ; but I believe the male 

 has not been found in the perfect stage in any other 

 part of the world. Mr. E. E. Green (1. c.) was the 

 first to discover the male puparia, containing pupae, in 

 this country, and I have received from Mr. Nicholson 

 a damaged specimen on a leaf of Spathelia simplex 

 which he obtained for me at Kew. In this country 

 the species appears to be quite immune from the 

 attacks of parasites, but in other countries it has
