Summary 
Wrack inhabiting larvae of three species of Coleoptera are des- 
cribed for the first time. Orthoperus scutellaris LeConte (Corylo- 
phidae) and Monotoma producta LeConte (Rhizophagidae) were 
reared, with the third larva being associated with Corticaria valida 
Fall (Lathridiidae). Spores of Helminothosporium sp. and Alterna- 
ria sp. (Fungi Imperfecti) were found in the guts of all three taxa.
