" I can assure you that I answered your letter and now 

 repeat the gist of what I wrote. As you will see from Farquhar- 

 son's letter, which I enclose, he made very complete arrange- 

 ments. But what happened was that Farquharson himself 

 on the day before he sailed left three small tins of larvae with 

 me. His boy, Joe, brought neither larvae nor food, nor did 

 any come by train, with the result that all the larvae died 

 without having shown signs of pupation." 



The letter from Farquharson, dated August 28, 1918, 

 contains the following passage — somewhat shortened — 

 together with two other references to observations published 

 in tbe 1921 Transactions : — 



" I wished to give you some insects in the hopes that some 

 of them wiU complete their life-histories in a few days after 

 I leave. In any case I'll trust to your good nature and send 

 them to you by Joe, and have arranged for tins of the chop 

 plant to be sent you by every down train till they are fully 

 fed. As a matter of fact the expectation is that they will die, 

 for it is possible that they cannot complete their life-histories 

 without passing a part of their lives chez the ant Camponofus 

 maculatus. If they pupate the imagos will emerge ten days 

 later." 



The letter also referred to the Dermestes larvae he 

 intended to leave (p. 436), adding that " one or two Diptera 

 may also breed out " ; and in conclusion he promised to send 

 Mrs. Connal a box of chocolates for Christmas " if that beast 

 is a Ceratopogon and not a Cecidomyiid " (p. 441). 



Notes on the life-history of a Bethylid (Hymenoptera) 

 OF the genus Cephalonomia Westw., observed at Oxford 

 BY Mr. a. H. Hamm. The Bethylidae are Fossorial 

 AcuLEATA. — Prof. PouLTON gave an account of the following 

 remarkable observations by Mr. Hamm and exhibited the 

 specimens referred to together with the type material of 

 Cephalonomia for micif or mis Westw. : — 



'' The minute female Hymenopteron (Bethylidae) exhibited 

 to the meeting was captured on August 4, 1918, in my garden, 

 22, Southfield Road, Oxford. She was walking on an old post 

 a few inches from the ground, carrying in her mandibles a 

 Coleopterous larva ( ? Cis) at least six times her size and
