A gamasid Avas found attached to the body of an adult of Alaus oculatus at St. Louis, Mo., by Mr. E. E. Fisher. This mite was under the wing covers.' Another mite {Chelifer alaus) is recorded- as a parasite of the adult Alaus oculatus. The writer has published ^ a record of a fly {Thereoa egressa Coq.) the larva of which actually attacks and feeds upon wirew^orms. The larva was found in a wheat field near Pullman, Wash.,and when found had its head and first four anterior joints within the body of a wireworm and was eating out the insides. This larva was brought into the insectary and fed upon wire- w^orms, of which it ate usually two a day. On June 10 it pupated, and on June 21- the adult fly emerged. Two other species of Therevidse {Psilo- cephala aldrichii Coq. and P. munda Coq.) were reared by the writer from larvae taken in the field, associated with wireworms, in the Pacific Northwest. These flies in their larval stages are prob- ably predaceous on elaterid larvae. Forbes mentions* rearing a parasitic fly from an elaterid larva. A Procto- trupes has been reared from an elaterid larva in England In the same work Curtis refers to a similar record bv.
