Exhibitions. 



Pupation of Timarcha tenebricosa. — Mr. Hugh Main 

 exhibited subterraria with larva and pupa of Timarcha 

 tenebricosa, and called attention to the colour of the pupa, 

 which was similar to that of the red fluid emitted by the 

 imago, and of the ova and newly moulted larvae. 



A DlPTERON NEW TO THE BRITISH LlST. Mr. J. E. COLLIN 



exhibited specimens of Humerus tuberculalus, Rdi., a Syrphid 

 new to the British List of Diptera ; also specimens of Eumerus 

 strigatus, a species under which it may easily have been 

 placed in collections. Both species had been reared by 

 Mr. J. C. F. Fryer from larvae found in Narcissus bulbs 

 grown at Taplow (Bucks.). 



He pointed out that though E. strigatus had been recorded 

 from the Continent as attacking onions and potatoes, in 

 addition to Narcissi, no such attacks had been noted in the 

 British Isles, indeed at Taplow onions grown between the 

 rows of the infested Narcissi remained uninjured. In 1917, 

 however, Eumerus larvae were found in a previously un- 

 recorded food-plant, viz. parsnips, grown in the Evesham 

 district of Worcestershire, and the specimens of E. strigatus 

 exhibited were some of those reared from these larvae. 



The headquarters of the genus Eumerus is the Mediterranean 

 region, and E. tuberculatum is an Italian species which has 

 remained unrecognised ever since it was originally described 

 in 1857. 



The modern use of the word " camouflage." — Prof. 

 Poulton said that he wished to enter a mild protest against 

 the modern use of " camouflage " for Protective and Aggressive 

 Resemblance (Procrypse, Procryptic, and Anticrypse, Anti- 

 cryptic). " Camouflage " did not appear as an English word 

 in Murray's Dictionary, but " Camourlet *' was in use in 1836, 

 with the following meaning : 



" A mine containing a small charge of powder, placed in a 

 wall of earth between the galleries of besieged and besieger, 

 so as, in exploding, to bury, suffocate, or cut off the retreat 

 of the miner on the opposite side; a ' stifler.' 



" 1836 in Penny Cycl VI, 197 I. Camouflet or Stifler."
