While many papers have appeared on various insects which inhabit fungi, only a few of them mention the specific or generic name of the fungus and it is such papers which have been listed below. The list is as complete as it has been possible to make it and includes only references to American literature. A few of the references relate to insects indirectly associated with certain fungi and not usually considered as funguous insects. The writer will be pleased to know of any omissions. COLEOPTERA.
