Dipteron

The next species of Diptera are two female specimens of Trichomyia, bred about the end of May, following which is a dipteron new to the British list, Brachycoma erratica, Mgn., of the family Tachinidæ, kindly identified with the other Diptera of our cherry stump, by Dr. Meade, of Bradford, who has fully described this new species on page 110 in the May number of The Entomologists Monthly Magazine, 1894.

A larval dipteron which has been interpreted as a roundworm.

This gall was brought to me ten years ago. From my notes I gather it was probably made by a dipteron, but I failed to rear the flies.

It is also a Pseudodipteron, that is, a false Dipteron; for at first they us'd to build a Dipteron, that is, a double Wing, or Row of Pillars about; but Hermogenes afterwards brought up the Custom of taking away the inner Row of Pillars, so to make the Walking-Place more open, which sort of Wings is call'd Psuedodipteron, because they imitated the Form of the Dipteron.

The first dipteron on Samos is dated by Buschor 560-550 B.C. or earlier (see below, pp. 199 f.).

It seems to have been the original Samian dipteron, laid down perhaps shortly before 560 B.C., that set the pace; and this great building not only excited the rivalry of the Ephesians but set the pattern for architectural forms on Chios also.
