while Mr. Buarr observed that it was not necessarily an indica- 
tion of high specialisation, since it was found in some very 
primitive insects. In answer to a question from Mr. CuaMPION, 
who said that in his experience of Tenebrionid beetles asym- 
metry of the mandibles was confined to the 3 3, Mr. GRAVELY 
replied that in the Passalids of which he had been speaking 
it was equally present in both sexes. 
A NEw Genus or Mymaripar.—Mr. F. Enock exhibited 
photographs of the ¢ and 2 of a new Mymarid, and read the 
following note :— 
During a short holiday at Hastings, I had the good fortune 
in sweeping to obtain an entirely new Mymarid, at Hollington 
Wood, near Hastings. After a long examination under the 
microscope, I failed to identify it with any of the known 
genera. On submitting the specimens, of which I obtained 
a male and female, to Mr. Chas. O. Waterhouse, he confirmed 
my opinion that I had captured something quite new, which 
we determined to name Neurotes iridescens. It is closely 
allied to Haliday’s genus Limacis, and we have placed it at 
the head of the British Mymaridae. 
Mr. C. O. WarEerRHOUSE corroborated Mr. Enock’s remarks 
and observed that the new genus was nearer to the Chalcids 
than any of the previously known Mymarids. 
Rare MyrMecopuitous Diprera.—Mr. DonisTHORPE ex- 
hibited specimens of the rare myrmecophilous Diptera :— 
1. Platyphora lubbocki, Verrall, two specimens bred out 
of his observation nest of Formica sanguinea on July 11 
and 26 last. Only two specimens have been captured (one 
by Dr. Wood in Herefordshire and the other by Mr. King 
in the New Forest) since Lord Avebury bred a specimen in an 
ant’s nest. He expressed his opinion that his two specimens 
had hatched from pupae of F. fusca given to the sanguinea 
colony as slaves. 
2. Aenigmatias blattoides, Meinert. A specimen of this 
curious little apterous Dipteron was taken in a nest of F. fusca 
at Nethy Bridge, July 21. It was originally taken by Meinert 
in a nest of F. fusca in Denmark. Subsequently Wasmann 
had bred a few specimens from F. fusca pupae in his nests, 
in Luxemburg.
