Reports to various Correspondents. 121 



" I feel confident if you locate the nests and galleries (and 

 probably only a few exist), that with the arsenic syrup you will get 

 rid of the pest." 



A Eeport on these pests in the Sudan has been pul^lished in 

 the " First Report on Economic Zoology " (pp. 158-163). 



OTHER SHORT REl'ORTS SENT. 



Insect destroying Telegraph Pole. — The piece of telegraph 

 pole brought by Lady Thiselton Dyer from Mentoue and sent to the 

 Director of the Museum was tunnelled by the Carpenter Bee 

 {Xylocopa ■violacea, Scop.), a large black bee with iridescent violet 

 wings, common in Southern and parts of Central Europe. 



Parasites in the Cabbage White Butterfly in Cyri;us. — 

 A specimen of the larva of the Large Cabbage White was sent to 

 Miss Bate attacked by hymenopterous parasites. They had kilh^d 

 the larva and proved to be Microgaster glomcratufi. The maggots of 

 the latter live in the butterfly caterpillar until mature ; then they 

 work their way out and spin the little yellow cocoons so commonly 

 seen surrounding the dead cabbage white butterflies in this country. 

 This parasite does a great deal of good in keeping those destructive 

 creatures down. 



An American Rose Cecid. — A minute Cccid, found on the 

 rose in Illinois, U.S.A., was sent for identification by Professor 

 F. M. Webster. The Cecid answers to those I have bred from roses 

 over here and what I identified as the Ceddomyia rosarum of Hardy, 

 the C. rosfe of Macquart and Bremi. The larvae of this species 

 live in small swellings on the back of the leaves of cultivated and 

 wild roses. The American pest is a different species (Neoccri'l.a 

 rliodophaga, Coq.), and attacks the rose-buds. A report with coloured 

 ])late is being prepared by Professor Webster. 



Lady-bird Enemies of the Diiurra Aphis in Sudan. — Two 

 Lady-birds prey upon theDhurra Aphis in the Sudan — (I.) Chilomcucs 

 vicina, Muls ; (II.) Coccinclla vndcdmpundafa. The larvte feed upon 

 Aphis as well as the adults. These specimens were sent by 

 Dr. Balfour, Director of the Wellcome Laboratories, Khartoum. 



Parasitic Cockroaches {Hemivicrn^i hanseni, Sharpe). — Some 

 parasitic Cockroaches were sent by Dr. Dutton, which were taken by 

 him on Oricefomijs ganihianus. The curious Cockroach-like insects 

 ^\•hiell he found on the large rat-like Cricctomys gamhianvs, in
