 Allied to A, sacchari, Ckll., In. Inst., Jamaica, Vol. I., p. 255. The habitat of 

 these scales, on yam roots, is remarkable ; a similar instance is offered by a new 

 Lecanium [L. batatce, Ckll., n. sp.) found by Mr. Barber in Antigua, on tubers of 

 sweet potato.

149.-A NEW FUNGUS.* 



A neiv species of Entopliyte, Cordyceps Lunti, n. sp. (Fungus), a 

 parasite on tlie larvce of an Elateridcc. By A. Giard. (See 

 Circular Note 21.) 



Mr. J. H. Hart, Superintendent of Agriculture in Trinidad, has 

 recently sent me a superb Entophyte found by his assistant, Mr. 

 W. Lunt, in the Botanic Garden of the Island. 



It is a Cordyceps, parasitic upon the larvae of an Elaterideae of 

 large size (45 mill, long), belonging, I think, to the group of the 

 Agrypnini. 



The whole of the body of the larva is covered by a downy felting 

 formed by the conidial state of the Fungus. 



The ascigerous receptacles spring from the ventral surface, the 

 one near the middle of the body, the other near the posterior quarter 

 of the larva. 



The first is nearly 5 cent, long, the second about 3 cent. 5. 

 Their form is that of a club regularly thickened and conical at the end. 



The peduncular portion is 2 cent, long and 1 mill. 5 wide, the 

 thickest part has a width of 2 mill. 5. The clubs of both receptacles 

 approach each other and have coalesced for a length of 4 or 5 mill. 

 The perithecia are irregularly distributed, more abundant on one side 

 than on the other and leaving at the top a small sterile space which 

 elsewhere is not so distinctly separated from the rest of the club. 



The whole of the Fungus, the portion underground and the head 

 ( capitules ) is of a beautiful orange red ; the perithecia only forming 

 fine brownish punctuations on the receptacular clubs. 



Cordyceps Lunti comes near, by its colour and general aspect, 

 Cordyceps caloceroides, Berk & Curt, found in Cuba on an undetermined 

 substratum, and very imperfectly described.
