have been difEcult, if not impossible, for Dr. Wandolleck to 

 do in the case of the other still more aberrant species — I con- 

 sider that I am justified in being the first to introduce this 

 interesting series of forms to science, especially as I have 

 been engaged for a long time past in collecting material for a 

 monograph on the Phoridee. Since, however, the anatomical 

 investigation of the allied form was already commenced some 

 weeks ago by Dr. Wandolleck, I am in addition handing over 

 to him adequate material for a similar purpose. From him 

 therefore we shall have to expect in the near future further 

 interesting results dealing with this group of forms. 



In the present paper I would merely add a few observa- 

 tions on the ethology of the species discovered by rae. I 

 found the insect in numbers in my wholesale captures 

 (" quantitativen Fangen ") which I made in the Bismarck 

 Archipelago, and particularly in the forest, with a dead bird 

 as bait. For obtaining creatures of this kind I can therefore 

 recommend my method of capture, which I have described in 

 detail in the ' Berichten der Academic der Wissenschaften in 

 Berlin,' Jahrg. 1896, ii. p. 17. At first on examining it 

 with the naked eye I took the insect to be a Sminthurus 

 (Podurid^). With us representatives of this genus are 

 frequently found among captures made upon carrion, bat in 

 the Bismarck Archipelago they appear to be absent. 1 allude 

 to the outward resemblance merely in order to facilitate their 

 possible discovery. Subsequently under the microscope I 

 actually considered the first specimen to be a Phora which 

 had lost its wings, so great is the resemblance to that genus. 

 I may add that 1 found a few specimens besides other carrion- 

 insects upon the flower of Amorphophallus^ an Aroideid, 

 which has an unpleasant carrion-like odour and grows almost 

 upon the ground. The insect is therefore decidedly a carrion- 

 feeder, like the rest of the Phorida^.
