 Geneeskundig Laboratorium over het Jaar 1921. [An Extract

The localities where Anophelines were found, both in 1921 and in 

 1920, are shown in a table. The occurrence of Anopheles suhpictus 

 {Myzomyia rossi) in Sumatra and Nias is noteworthy. At Weltev- 

 reden Armigeres {Desvoidya) obturbans has peculiar habits. The 

 females bite at about 6-6.30 p.m., and then disappear almost entirely 

 about an hour later. At other hours they very seldom attack man. 



A fly, Sarcophaga sp., was bred from larvae from the ear of a sufferer 

 from external otitis due to bums.

Canine demodectic mange, which occurs in many parts of Italy, 

 is difficult to cure owing to the protected position of the parasite, 

 Demodex. The following method is recommended as giving excellent 

 results. The coat must be brushed and thoroughly washed daily with 

 tepid water, soap and creolin. The dried coat must be rubbed with 

 cotton wool soaked in ether, and this must be followed by a second 

 rubbing with ether containing 1-2 per cent, of iodine. ThjTHol 

 0-25 per cent., or salicylic acid, 1 per cent., may be substituted for 

 the iodine, but the latter is preferable. If the entire body is affected, 

 it should be divided into three, four or even five areas for consecutive 

 treatment, so as to minimise the chilling action of the ether.

The points of difference in the anatomy of the larvae of Anopheles 

 bifurcatus, Theobaldia annulata and Cidex pipiens are indicated, and 

 the tracheal system of various species is dealt with.

In Mochlonyx skin and tracheal respiration are complementary to 

 each other, and though neither form is able to supply the necessary 

 amount of oxygen alone, yet up to a certain point they can replace 

 each other. The observations on Ctdex, Anopheles and Theobaldia 

 confirm the statements made by Koch [R.A.E., B, vii, 49].
