JOXJENAL OF HOETICULTUKE AND COTTAGE GARDENER. 



[ October 27, 18««. 



Caddice Fly, on the laxvae of which the Ichneumon larvse 

 subsist. 



Blr. Bates and Mr. Cutter gave an account of the destruc- 

 tion of large quantities of the seeds of different species of 

 Palms collected in Brazil, and sent to this country as articles 

 of horticultural commerce, especially the nuts of Maximiliana 

 regia, by the larvie of several kinds of Bruchidte of large 

 size, belonging to the genus Caryoborus. In some instances 

 the destruction had been so great that nearly the whole 

 cargo had been destroyed, as many as five larvse being found 

 in a single nut. 



Mr. J. Young sent a notice of the annoying habits of the 

 House Ant, which had been found infesting a house in 

 Guildford Street in great numbers. Some years ago the 

 same insect had been brought under the notice of the So- 

 ciety, when it had been found that the most practicable 

 manner of getting rid of the pest was to lay down smaU 

 pieces of meat in its burrows. These were very soon covered 

 with the ants, which might be easily destroyed by dipping 

 the meat for a few moments in boiling water. 



Dr. Baly read a memoir containing descriptions of a con- 



siderable number of new species of phytophagous Beetles 

 of different genera, natives of India, Australia, and the 

 islands of the Eastern Archipelago. 



Mr. Stainton gave a condensed account of the entomo- 

 logical portion of the proceedings at the recent meeting of 

 German naturalists held at Stettin, under the presidency of 

 HeiT Dohm ; when Dr. Loew read a memoir on the European 

 Trypetidae, illustrated by figures of large size taken by pho- 

 tography. Herr Kraatz communicated a memou- on the 

 European species of Melolontha, with the view of proving 

 that many species found in different countries of Europe, 

 hitherto considered as distinct, were only geograpliical mo- 

 difications of the well-known Cockchafer Melolontha vul- 

 garis. Dr. Suffrian read a notice of fungi parasitic upon 

 insects ; Dr. Hartig on a new genus of Aphidce found at the 

 I roots of Fir trees, having the tibia' and tarsi united. An 

 account was also given of the satisfactory results of the 

 Prussian expedition to Japan, with the view to acclimatise 

 the Japanese variety of Bombyx luori, the common Silk- 

 worm, which was found to be much hardier than the Chinese 

 variety. 



ONCIDIUM SAECODES (Flesh-like Oncid). 

 Nat. ord., Orchidacese. Linn., Gynandiia Monandria. Syn., Oncidium Rigbyanum. 



Specific character. — Plant an epiphyte. Pseudo-bidbs some- 

 thing cylindrical, 3 inches long. Leaves 2 or 3 inches on 

 the summit of each pseudo-bulb, erect, lanceolate. Flowers 

 paniculate. Scape 1 foot long. Sepals and petals bright 



lemon-yellow, varied in the centre of each, with numerous 

 dark crimson spots. Labellum large, spreading, two-lobed, 

 somewhat ciu-led at the edges, bright yeUow, spotted with 

 dark crimson. 



This Oncid was purchased by Mr. Henderson, of Pine Apple 

 Place, London, at a sale of the nursery stock of the late Mr. 

 Rigby, a plant-grower at Brompton. It was sent through a 

 friend of Mr. Eigby's to Brompton in 1842, and is a native of 



BrJizU, but by whom it was first discovered, we regret to say 

 is iinkno'svn. It il(iwers freely in March and April in .a jjot 

 filled with peat, wfU drained, and placed in a cool part of the 

 house, and requires the same treament as other Orchids.Jl , 4
