important forms. It appears that most of our known species are 

 internal parasites of lepidopterous larvae; but a few are said to 

 attack the larvae of fungivorous Coleoptera. This rather marked 

 variation in habit has been noted among the European species of 

 Meteorus also, species like obfuscator Nees, profligator Haliday, and 

 Jilator Haliday having been mentioned as parasites of fungivorous 

 beetle larvae.^ There is not sufficient correlation between this habit 

 and structural characters, however, to permit the separation of the 

 parasites of Coleoptera from those attacking Lepidoptera as distinct

taxonomic groups. Furthermore, I believe more exact rearing data 

 are necessary before we can entirely accept the records from beetle 

 larvae. It is quite possible that in some instances at least lepidop- 

 terous, and not coleopterous, fungivorous larvae were the hosts. 

 One of our species, humilis Cresson, has been recorded from Orchesia, 

 and also from Tinea, indicating, if the records are correct, that no 

 discrimination is made between lepidopterous and coleopterous 

 larvae, providing only that both are working in fungus. 



The full-grown larvae of most of our species of Meteorus make 

 characteristic pensile cocoons, often found hanging from limbs or the
