REPRESENTATIVES of all the grand divisions of the Insects and 

 Crustaceans have been found in this cave, and if no worms have 

 yet been detected, one or more species would undoubtedly reward 

 a thorough search. 



We will enumerate what have been found, beginning with the 

 higher forms. No Hymenoptera (bees, wasps, and ants) or Lepi- 

 doptera (moths) are yet recorded as being peculiar to caves. The 

 Diptera (flies) are represented by two species, one of Anthomyia 

 (Fig. 122) or a closely 

 allied genus, and the sec- 

 ond belonging to the sin- 

 gular and interesting ge- 

 nus Phora (Fig. 123). 

 The species of Antho- 

 myia usually frequent 

 flowers ; the larvae live in 

 decaying vegetable mat- 

 ter, or, like the onion 

 fly, attack healthy roots ; 

 while the maggots of 

 Phora live in decaying 

 substances. It would be 



Anthomyia. 



presumptuous in the writ- 

 er to attempt to describe these forms without collections of spe- 

 cies from the neighborhood of the cave, for though like all the 

 rest of the insects they were found three or four miles from the 

 mouth, yet they may be found to occur outside of its limits, as 

 the eyes and the colors of the body are as bright as in other 

 species. 



Among the beetles, two species were found by Mr. Cooke. The
