chid houses in New Jersey, came to my notice too late to with- 

 draw my own description of the same weevil from publication 

 in the last volume of these Proceedings and was my first intima- 

 tion that the species was attracting attention elsewhere. 



Mr. Weiss informs me that 17 specimens were found, usually 

 singly on various species of Cattleya especially on C. gigas during 

 irregular visits to an orchid house at Secaucus, N. .1., between 

 May and August of 1910. The adults were quite conspicuous, 

 crawling and feeding on the leaves and bulbs and doing much 

 damage. Their chief injury appears as before stated to be done 

 by the larva developing in the pseudobulbs. 



Mr. Weiss has helped me to reassemble all of his specimens 

 except the second one he captured which he sent to Mr. Cham- 

 pion and which became the type of cattleyae being most likely 

 now deposited in the British Museum. Five of these sixteen 

 specimens are CnolUs cattleyae Champ, but the other eleven exam- 

 ples are not that species but are C. forbesii Pascoe, this deter- 

 mination having been corroborated from photographs sent by me 

 to Mr. Champion. 



AIi\ S. B. Fracker of Wisconsin writes that adults have been 

 taken in the Milwaukee greenhouses in January, March, June, 

 August and September and that larvae were found in all stages 

 (lining this time, pupation occupying at least two but not more 

 than four weeks and that larvae lived under the abnormal condi- 

 tions of his office for at least four months without pupating. 

 Two partly grown and two apparently full fed larvae were re- 

 ceived alive from Mr. Fracker on September 14; the two smaller 

 ones were here introduced into fresh, artificial holes in the healthy 

 leaf bulbs of a small Cattleya where they apparently made them- 

 selves at home and excavated the interior of the bulb, but when 

 the latter were cut open in November both larvae were found to 

 be dead. One of the larger larvae was ready to pupate when re- 

 ceived but was unable to cast the larval skin and was preserved 

 September 25; the other took some weeks to prepare for pupation 

 which it accomplished about November 1 and finally issued as an 

 adult November 20, after which it took nearly a week to harden. 

 It lived about two months upon a Cdttlfi/a plant which was 

 finally killed by the feeding of the weevil. 



Mi\ Sanders recently infonned me that, ten or twelve specimens 

 were preserved from (he Milwaukee 1 infestation, but of these the 

 writer has had access to only seven. Thus including the single 

 specimen found in Washington, 1). C.,in 1913, and the one reared 

 by the writer, these notes are based upon a series of twenty-five 

 specimens which have been assembled through courteous loans 

 from the collections cited below, and the examination of this 

 series is of considerable interest since the three previous de-
