Maisoxxeeve. — Note sur le Sphoeria militaris, Ehrh. considere

 of its origin, extracted, it would seem, from the proceedings of 

 the meeting). 



In the department of the Grironde, the caterpillar, which de- 

 vours the leaves of the young shoots of firs, had made such 

 ravages in the year 1858, that the proprietors were alarmed for 

 the fate of their woods. This fact was followed by the appear- 

 ance, in immense quantities, of SpJi. militaris, Ehrh., one of the 

 club-shaped species of Sphoeria parasitic on the larva? of insects, 

 and which is remarkable for its golden red colour. M. Durieu 

 de Maisonneuve, having visited the woods in December, 1858, 

 observed at once several individuals of this Sphoeria parasitic 

 upon the caterpillar, which was enclosed in its cocoon, not having 

 yet passed into its chrysalid condition. In all the other parts of 

 the woods which he visited, he observed the same Fungus, at- 

 tached to the same caterpillar, dead, and buried in the ground. 

 M. Tulasne has observed that the perfect state of Sph. militaris 

 is much more rare than its secondary or isarioid condition ; and 

 that this latter is more rare than its primary or byssoid state ; 

 and inasmuch as the perfect plant "occurred in such quantities 

 that the ground round the diseased trees was covered with it, the 

 quantity of caterpillars destroyed by this Sphoeria in all stages of 

 its growth must (in the author's opinion) have been prodigious.
