deep velvety brown triangular patches, the maculations being 

 entirely absorbed therein. 



Living LARViE of Blatta. — Mr. Hugh Main showed living 

 larvae of Blatta germanica to illustrate their colourless condition 

 on first emergence. 



Rare British Beetles and dipterous parasites. — Mr. 

 H. St. J. Donisthorpe exhibited examples of {a) Agrilus 

 higuttatus, F., taken in numbers in bark of old oak in Sher- 

 wood Forest, July 1908. It had not been taken in Britain for 

 about thirty years, this being the first record for the Midlands. 

 Formei'ly it occurred in Darenth Wood, but is not found there 

 now ; (6) Pyroptef)'us affinis, not uncommon in Sherwood Forest, 

 July 1908 ; (c) a species of Phora, with pupae bred from 

 larvae which came out of the body of a Clerus formicarius taken 

 alive in Sherwood Forest, July 1908, with the Agrilus, and 

 probably parasitic on it ; {d) Trogolinus anglicanus, Slip., a 

 specimen taken at Bembridge, August 3rd, 1908, with a speci- 

 men from Plymouth, and only known before to occur in New 

 Zealand and at Plymouth, where it was discovei'ed by Mr. 

 Keys. This capture seemed to dispose of the idea that it could 

 have been introduced from New Zealand ; (e) Phyto melano- 

 cephala, Mg., bred from wood-lice taken at Bembridge, I. of W., 

 August 1908, with pupa3, and a wood-louse with dipterous 

 pupa in situ. The life-history of fly was hitherto unknown, 

 though the larvse of Bhino])hora atramentaria, Mg,, a nearly 

 related species, have beenrecorded as parasitic on Oniscus asellus. 



Gynandromorphous pieris. — Mr. A. Harrison exhibited a 

 gynandromorphous example of Pieris na2n, bred from parents 

 taken in North Cornwall this year. 



Rare British Neuroptera. — Mr. E. R. Speyer exhibited a 

 case of rare and interesting dragonflies taken in the British 

 Isles in 1908, including (a) Sympetrum fonscolomhii, Selys. A 

 $ and 5 , taken in Hertfoi'd shire on June 24th and July 

 27th respectively. The specimens were evidently part of a 

 migration, the $ , being the first taken in England, since that 

 announced by Mr. Boyd in Cornwall in the E. M. M. Vol. 39, 

 p. 201 (1903). Mr. K. J. Morton is of opinion that the 

 insect takes more than a year to arrive at maturity, and, 

 therefore, those taken in England are probably in their second
