dusky scales along the median nervules. Size of trifolii. Two specimens, 

 Santa Clara, California, May 22, collected by Baron Osten Sacken. 



This inconspicuous form can hardly be a geographical variety of tri- 

 folii, as the subterminal line seems quite different in character, but the 

 markings are otherwise very nearly the same. 



CORDYCEPS RAVENELII ON THE LARWE OF 



PHYLLOPHAGA. 



BY DR. H. A. HAGEN, CAMBRIDGE, MASS. 



I am indebted to Mr. P. H. Mell, Auburn, Ala., for this beautiful 

 species. This fungus is described by Rev. N. J. Berkeley in Journal of 

 Proceed. Linn. Soc. Lond., 1856, vol. i., p. 159, pi. i,f. 4, after specimens 

 in Rev. M. A. Curtis'' herbarium, and collected by Mr. H. W. Ravenel in 

 S. Carolina. I was shown by Prof. W. G. Farlow, who possesses now the 

 herbarium of Curtis, the original types, which are identical with those 

 collected by Mr. Mell — as far as identity can be ascertained without 

 making cuts for microscopical examination. Mr. Curtis remarks : " S. 

 Carolina in May ; grows out on first joint of thorax on one or both sides 

 of dead larvae of Ancylonycha (Phyllophaga), buried one to two inches 

 under ground ; also from Texas, C. Wright. The fungus is brown. Head 

 two inches or more high, flexuous, compressed or grooved, at first minutely 

 tomentose, at length smooth ; head 3/£ inch long, cylindrical, but slightly 

 attenuated at either end. Peritheria free, ovate ; asci very long j sporidia 

 very long, filiform, breaking up into joints 0,0001 inch long." 



It would be impossible to determine the larva from Alabama nearer 

 than as one belonging probably to Phyllophaga. All we know of the larvae 

 of this genus (even of Melolonthidae) from U. S. is a notice of Ph. 

 puncticollis in Sillim. Jour., viii., p. 269, of Macrodactylus spinosus and the 

 descriptions and figures of Ph. fusca, which are not sufficient. From 

 Europe are some species described, but after all the larvae of this family 

 need to be worked out and studied entirely as new.
