characteristic strongly defined Y-shaped 6hitinisation in the apical area ; 

 in all three genem this is connected with the posterior margin of the 

 wing towards the apex by a strong vein not figured in Heller's plate. 



As regards the synonymy of the species the identity of F. adelotopus 

 Heller with F. hlattoides Blair is practically certain, the first-mentioned 

 name having priority ; that of F. pilosua Pic with F. cliatanayi Blair, 

 both hairy insects, the former described from Calcutta, the latter of 

 iiiiknovvn locality, is uncertain without comparison of specimens.

A NEW ABEERATION OP C08YMBIA {EPHYRA) PENJDULABIA Cl. 

 BY F. C WOODFORDE, B.A., F.E.S, 



I obtained ova of this species from a female captured in North 

 Staffordshire in May 1917. The offspring emerged in May 1918, most 

 of them being intermediate between the typical form and ab. suhroseata 

 mihi (which Mr, Prout informs me that he does not now consider to be 

 identical with ab. decoraria Newman), but one of them was different 

 from any of the others and from any other form of the species that I 

 have seen. The ground-colour of this specimen is darkish grey. The 

 1st and 2nd lines are indicated by rows of black dots rather larger than 

 usual, the 2nd in both primary and secondary wings being bordered by 

 a naiTow whitish band, faint on the inner side, but conspicuous on the 

 distal side. The ocelli are very conspicuous. A very narrow, indistinct 

 reddish band crosses the centre of the wing. The cilia are whitish. 

 The insect so much resembles a dark form of G. orhicularia Hb. that I 

 propose naming it ab. orhiculoides. It is now in the collection of the 

 Hope Department, Oxford University Museum.

A NEW BRITISH HETEROPEZINE FLY. 

 BY F. W. EDWARDS, B,A., F.E.S, 



Tn Messrs. Bagnall and Harrison's admirable Preliminary Catalogue 

 of British Cecidomyidae (Trans. Ent. Soc. Loud. 1917, pp. 346-420) 

 only one member of the subfamily Heteropezinae is included, and. even 

 that has not been determined specifically. Doubtless many occur with 

 us ; I have myself come across their paedogenetic larvae in several 

 localities under bark, and once also in a fungus, while Dr. D, Keilin
