A histologic study was carried out on tissue-reactions after insect bits in 9 patients with various primary diseases. The clinical and cellular reactions to the bite in the epidermis varied, according to the length, intensity of toxity of the insect bit. The dermal infiltrate was similar in almost all cases and corresponded to a cellular immunologic reaction of the early or late type, as is also to be seen in trichophytin and tuberculin-reactions. Tere was clearly no relationship between the character of the dermal infiltrate and the basic disease. We also found no change in the dermal infiltrate due to special medicaments. Even corticosteroids did not suppress the dermal cellular reactions. There was also a striking absence of eosinophil leucocytes in the dermal infiltrate.
