a narrow slit, Midler remarks that odours could hardly bu freely emitted. He therefore 

 hazards the speculation that the anal tufts of hair might be introduced into the pouches, to 

 be impregnated there with odoriferous matter, A proposition like this, though probable, 

 necessarily requires verification, which an observer of such exactitude aud patience as Muller 

 will doubt loss endeavour to supply. It Is possibly towards such at present unproved postulates 

 that Karl Semper, quoting Jaeger,* remarks that enough has been done in the way of 

 philosophising by Darwinists, and that the task that now lies before us is to apply the test of 

 exact investigation to the hypotheses we have laid down. 



Tins genus represents, with the other members of the Ikinaitue, a "protected" group of 

 insects, which, from distastefulness or other causes, enjoys an immunity from the attacks 

 of birds and other enemies- The testimony to this fact is undoubted aud too voluminous to 

 insert here; but even in tenacity of life Damn's is remarkable, and Mr, Trimen f records how 

 South Afrieau specimens, caught, pinched and pinued by his native collectors, would nearly all, 

 on the withdrawal of the pins, ** fly off in a ' nonchalant' manner, as if nothing had befallen 

 them/' Mr, MeldolaJ was disposed to consider (and with good reason) that these insects 

 possess an immunity after death from the attacks of mites and other museum pests. He had 

 in his possession a box of old Indian insects, the greater part of which had been demolished by 

 mites; the only surviving specimens, in addition to a / being Danaids. This view, however, 

 will require further confirmation, as in some East African insects which have lately passed through 

 my hands, specimens of D. dorippiLs have the bodies nearly destroyed by these attacks. 



Seven species alone are at present known from the Malayan Peninsula. Criiger, § in a 

 short notice of Malaecan Lepidoptera, refers to another species, I), atfhut, but this may prove 

 to rest on a mistaken determination,
