ON SOME WEEVILS ATTACKING ORCHIDS. 

 BY G. C. CHAMPION, F.Z.S. 



At the request of Mr. H. B. Weiss, of New Brunswick, N. J., 

 U.S.A., I have drawn up descriptions of two species of Curculionidae, 

 a Chains and a Diorymellus (a genus of Barina), found attacking 

 orchids from Brazil, Colombia, Central America, &c., in a greenhouse 

 at Bergen County, New Jersey. Mr. H. S. Barber, of the U.S. Dept. 

 of Agriculture, Washington, had previously sent me a photograph of 

 the imago, larva, and pupa of the same species of Gliolus, from speci- 

 mens found in a local orchid house at Milwaukee, Wisconsin. Mr. C. 

 R. Crosby, too, had also forwarded an example of the DiorymeUus for 

 determination ; tliis was found attacking orchid roots in a greenhouse 

 at Ithaca, N. York. Another Barid sent by Mr. Weiss, found feeding 

 on the flowers of Dendmhivm (an eastern genus of orchids) in the 

 same place in New Jersey, proves to be Baridiuft orchivora Blackb., 

 described from an example captured amongst introduced orchids in 

 Queensland. This species belongs to the genus Acypothens Pasc. A 

 third Barid, Aryjwthevs (Baridius) aterrimus 'G. Wat-erh., is known to 

 attack Phalae.nopns and Deridrobinm, and also to feed upon flowers of
