authorities, occurs in the egg-stage. The habits of Taeniorhynchus 

 {Mansonia) richiardii in Denmark have already been recorded [see 

 this Review, Ser. B, vi, p. 182]. No CuUcine thus hves in lakes or 

 other large waters. The imagines are remarkably stationary, 

 generation after generation remaining in the same forest or farm. 



In Anopheles maculipennis and A. bifvrcatus, the larvae are green or 

 broMTiish according to the character of the water in which they occur 

 during the summer ; they are always found near the edges of grass- 

 bordered ponds. A. maculipennis hibernates as an adult, fertihsed 

 female in outhouses, stables, etc., while A. bifurcatus hibernates as a larva, 

 and the adult, which as compared \\ith that of A. maculipennis is a 

 true forest mosquito, is found only up to October. The mosquitos 

 of this genus have only one generation a year in Denmark. The habits 

 of Anopheles plumbeus {7iigrip)es), the third Danish Anophehne, have 

 not been studied.

In April and May 1918 enormous numbers of Simuhid flies appeared 

 in Jutland, Denmark, coinciding ^vith the sudden occurrence of hot 

 weather. In some districts several deaths among cattle were recorded, 

 in one instance 30 dying in a single district in three days. The author 

 reviews all the known facts about similar outbreaks of Simuliids, 

 including those of an earlier date in Denmark. These have usually 

 been in Jutland, where the largest rivers in Denmark occur. The 

 serious efTect of the bites of these flies on cattle must be due to some 

 poison, which especially acts upon the nerves of the heart much as in 

 poisoning with digitalis. In treatment heart-stimulating remedies 

 are therefore of special importance. As a preventive measure the 

 smearing of the less hairy parts of the skin with strongly odoriferous 

 substances such as petroleum or creolin is recommended.

The author has found sulphur ointment quite reUable in all cases 

 of infestation with these hce, and less injurious than the mercury 

 ointment formerly used.

The mite, Cheiletiella parasitovorax, lives normally in the fur of 

 rodents, but the two cases here recorded in man were due to infections 

 from domestic cats. The symptoms were red, itching and raised 

 spots on the neck and limbs.
