58 THE entomologist's record. 



was embellished with 23 coloured plates, and contained a chapter on 

 the remedies against the Corcidiw. It also contained the descriptions 

 of 67 species, and much information concerning them that was then 

 quite new to us. Subsequently, and up to the time of his death, Mr. 

 Maskell continued to give us the the results of his labours, publishing 

 them annually in the 'Transactions referred to above. Dr. W. W. 

 Froggatt has thoroughly dealt with that remarkable group of Aus- 

 tralian gall-making Coccids, forming the subfamily Brachyscelinac, 

 most of which, if not all, are peculiar to the Eucalypti of that country. 

 Other workers have contributed to our knowledge of this family but 

 Dr. Froggatt's publications give the most complete account of these 

 insects. 



The Cingalese Coccids are now being monographed by Mr. E. E. 

 Green, who has already published two parts of his elaborate work, to 

 the end of the Diaspinac. Ceylon is evidently rich in its Coccid fauna, 

 and it is impossible to say to what extent Mr. Green's Avork will run ; 

 but I am certain of this, that his work in the end will prove a lasting 

 memorial to his great skill and untiring energy, and that his delinea- 

 tions will leave nothing to be desired. A few other odd species have 

 been described from the Oriental region by myself and other workers, 

 but much remains to be done. 



Africa has as yet received comparatively little attention at the hands 

 of coccidologists. The Rev. A. E. Eaton made a small but interesting 

 collection of Coccids in Algeria, which I described in the Transactions 

 of the Kntomolof/ical Societij of London, in 1896. A few species have 

 also passed through my hands from the West Coast, and from British 

 Central Africa, and the Government entomologist at Cape Town, Mr. 

 Lounsbury, is working out the species of the South. 



In Europe, since the publication of Signoret's Essai, there have been 

 comparatively feAv workers. Dr. Karel Sulc, of Bohemia, has worked 

 at the Coccids of his own country, describing a few new genera and 

 species, and we trust will continue his researches. Dr. Gustavo 

 Leonardi, of the Royal School of Agriculture, Portici, Italy, has of 

 recent years given us several most valuable contributions from his pen, 

 the most noteworthy of which is his elaborate and exhaustive mono- 

 graph on the genus Aspidiotus'''- , which the author divides into several 

 more or less natural subgenera. This work has much facilitated the 

 study of this extensive genus. It should also be added that Dr. 

 Leonardi has paid considerable attention to the physiology of the 

 Coccidae, and has published elaborate work on the subject. In the 

 Channel Isles Mr. W. A. Luff has discovered many interesting species, 

 including the unique Kxeretopus formiceticola, Newst., which at the 

 time of its discovery was the only Coccid known to possess two-jointed 

 tarsi. Mr. Cockerell has now described a Coccid possessing the same 

 character. 



Up to the year 1887 the English works were fragmentary and 

 most inaccurate, but at that time Mr. J. W. Douglas began a series of 

 articles on British and Foreign Coccidae, in the Entowolot/isf s Monthly 

 Mar/atine, which he continued till the year 1894, when he then com- 

 pleted his 27th article. Needless to add these were very thorough and 

 contain a vast amount of valuable information to the student of the
