154 ENTOZOICAL FUNGI. 



the fungus was evolved while it was yet living, or began to grow only 

 after its death. Perhaps not, but it is probable the plant began to grow 

 while the animal was in existence, but the vegetable life predominated 

 over the animal life and destroyed it. 



Kirby, vol. iv, p. 208, mentions the pu-pa of a species of Tettigonia 

 (closely allied to the grasshopper^) in his cabinet, which has a fungus 

 "with a twisted thickish stipes and oblong head, springing up in the 

 space between the eyes." He observed something similar, but longer, in 

 the grub of some large beetle in a collection in Paris, and he noticed 

 something of tlie kind on the rostrum of a calandra., (Genus of beetles.) 



In vol. 8 of Silliman's Journal, there is a communication on this sub- 

 ject with a well executed plate, representing a fungus growing out of 

 the head of the larva of mcl-oloniha^ (May-bug.) This grub is about one 

 inch and a half in length, and is common in meadows, and destroys the 

 grass, corn, and other fruits. It is often found under stones in moist 

 places. It is not unusual to find a number of them which have vege- 

 table "sprouts," sometimes three inches long, proceeding generally from 

 between the head and under part of the thorax, and in a few instances 

 from the mouth. Commonly there is one to each grub, though some- 

 times there are two. In every instance, the grub is not only dead, but 

 in a state of decay, and the "sprout" rising above the ground indicating 

 where they may be found. 



A friend informs me, that he has seen a similar sprout growing out 

 of the body of our mole cricket, ( GriillotaJpa.) 



The accompanying cut represents a larva of a Icjndopterous, (butter- 

 fly) insect, 



which is now in my cabinet, having a fungus about six inches in length 

 growing out of its head. It is here represented in its natuaral size. It 

 comes from New Zealand, where it is not uncommon and feeds on the 

 sweet potatoe ( Convolvulus batatus.) The fungus is Sphacria Rohertsi,
