The Orchid Thrips : Anaphothrips orchidaceus, Bagnall. 



By UICIIARl) S. BAGXALL, F.L.S , F.E.S. 



Until recently I was under the impression that this pretty little 

 species confined its attentions solely to the leaves of orchids. When 

 an infested orchid is in flower, however, A. oychidacens and its larvae 

 forsake the leaf for the flower, and may be found sheltered in numbers 

 under the corolla, and, feedintj- upon the tissues of the petals, it soon 

 renders a flower unsightly and unmarketable. Owing to its seclusive 

 habits, ordinary fumigation, etc., is of little use in dealing with the 

 orchid thrips, in fact the only way, I think, is to institute periodical 

 searches and clean the plants by picking up the insect and its larvas 

 with a camels' hair brush, and killing them by immersion in alcohol 

 or other destructive agent, a laborious method it is true, but apparently 

 the only safe method. 



The Rev. James Waterston has recently sent me several tubes of 

 A. orcltiilarcKs from the Royal Botanic Gardens, Edinburgh, found 

 chiefly on Maadecallia coccinea. There are one or two specimens in 

 Mr. Waterston's parcel from Ci/pn'pcdiii)ii actaeiis and of the larvae 

 from Oncidiinii and Hnjiidepis. Last year I found the form on 

 i'lipriju'dittiii at Copenhagen, on Li/castcs skinneyi, Cuprijiediniii spp. 

 at Gothenburg, and on ('ipid)idiiiiii and Kpidendnm at Christiania, and 

 have had it sent me from Holland by the Director of the Leyden 

 Museum.

While studying some of the Pab^arctic Plebeiids in the British 

 Museum collection, in July 1910, 1 came across several butterflies from 

 Lsmailieh, which had been doubtfully identified with L. (jalba, by H. 

 J. Elwes. These insects were, in my opinion, simply small specimens 

 of the Egyptian summer race of Zizeni li/sinion, lib. I then repaired 

 to the first picture-book on which I could lay my hands, to wit Dr. A. 

 Seitz's work on the Pahearctic Macrolepidoptera. Here I found a 

 figure of i/alba, which bore a great resemblance to the above mentioned 

 specimens and a very brief description of the insect, in which it was 

 stated that </alba was not easily distinguishable from h/sinmii, that it 

 occurred in Syria, and that it had been taken at lsmailieh. 



Now, leaving aside for the moment the question what the insect 

 figured by Seitz and doubtfully identified with i/alba by Elwes really 

 is, I should like to call the attention of lepidopterists who are 

 interested in the Pahtarctic butterflies to the original description of 

 (jalba, published by Julius Lederer in 1855 ("Beitrag zur Schmetterlings- 

 Fauna von Cypern Beirut und einem Theile Klein-asiens." Aus den 

 Schriften des zoologisch-botanischen Vereins in Wien, 1855) with
