Proceedings of the hinncean Society. 



Nov. 5, 1839. — Edward Forster, Esq., V.P., in the Chair. 



The Rev. William Wood, B.D., F.L.S., exhibited specimens of a va- 

 riety of Typha angustifolia, remarkable for its small size, and the 

 shortness of its female catkins, collected by himself in the extensive 

 marshes situate between Sandwich and Deal. 



Read, "Descriptions of some new Insects collected in Assam, by 

 William Griffith, Esq., Assistant Surgeon in the Madras Medical Service." 

 By the Rev. F. W. Hope, M.A., F.R.S., & L.S. 



The insects described in this paper, some of which are remarkable for 



their size and splendid colours, were mostly collected in Assam by 



Mr. Griffith, during the stay of the late Scientific Mission from Calcutta, 



to which he was attached. They chiefly belong to the longicorn beetles, 



and to the family of Lamiadce. The following are the characters of the 



new genera and species : 



LAMIA. 



1. L. Horsfieldii. 



Long. lin. 26 ; lat. lin. 85. 



Corpus cinereum ; antennis corpore longioribus, elytrisque flavo-creta- 



ceis maculisque ornatis, antennae articulis tribus primis subscabris. 



This species, which has been named in compliment to Dr. Horsfield, 



is the largest of the family, and is nearly related to L. catenata of De 



Haan from Japan. 



G. N. EUOPLIA. 



Corpus subdepression. Antenna lamiseformes, fere ut in Omacantha. 

 Thorax utrinque spinosus, dorso punctulatus. Elytra depressa, api- 

 cibus 2-spinosis spina suturali minore, lateralibus majoribus. In 

 reliquis Lamia convenit. 



1 . C. polyspila 



Besides the one enumerated, the author possesses five other species, 

 all natives of India, and which still are undescribed. 



G. N. OPLOPHORA. 



Caput fere quadratum. Mandibulee falciformes. Antennce corpore paullo 

 longiores, articulis basi pallidis. Thorax utrinque armatus, dorso 

 fortiter rugoso, tuberculo in medio disci posito. Elytra thorace 

 4-plo longiora, basi sinuata subscabra, gradatim e humeris ad 

 apicem magnis tudine decrescentia, apicibus rotundatis. Corpus 

 infra annulis abdominis ad apicem sensim attenuatis. Pectus valde 

 convexum, mucrone armatum. Pedes difformes et robusti.
