Behavioural and metabolic reactions of fornmoschistus minutus (Pallas) exposed to various degrees of hypoxia were studied. At 15°C and 20%0 mortality was 50% at 15.2% oxygen saturation. Avoidance and oxygen saturation showed a linear inverse relationship. At levels lower than 60% saturation increased activity occurred; avoidance was significant at 30% saturation. Active, routine and standard MO, correlated linearly with weight at 6 and 15" C (salinity = 19°%, ,) . During hypoxia a t , 15" C routine MO, rose significantly at 6&50% and 4&30% saturation expressed either as MO, during longer periods at night or MO, at shorter intervals during the day. Standard M O , was unaffected by hypoxia at 15" C. Haemoglobin concentration was significantly increased when P . minutus was acclimatized to 35% saturation.

Out of a sample of Tineid moths collected by H. Höne in China 50 years ago a new Scalidomia species is described. Together with specimens of Dasyses barbata Christoph this material allows to discuss some problems of both distribution and relationships of genera commonly summarized under the subfamily Hapsiferinae.
