elusive, and I was getting anxious to be doing serious work in that direction. 

 It may be worth while, however, to record the species I found in the weed : 

 Exaleochara morion Gr., Oxypoda opaca Gr., Tachyusa atra Gr., Atheta 

 eknujatula Gr., A. longiuscula Gr. {vicina), A. trUmi/iduin Kr., A. oblita Er. ( J ), 

 A. pulustris Kies., A. sordida Marsh., A. atrmnentaria Gyll., A. fungi Gr. 

 (var.), A. longicornis Gr., Philonthiis ventrnlis Gr., Gahrius nigritidtis Gr., 

 G. pennutus Sharp, Jiantholinas linearis 01., O.vytelus rugosus F., 0. laqueatns 

 Marsh., O. nitidulus Gr., O. sculptus Gr., Homalium excavation Steph. The 

 remainder of my time was devoted to the Cathormiocerus search, and by 

 persistently setting tiaps I succeeded in coaxing four specimens from their 

 subterranean retreats before I returned home. Rain fell a few hours after I 

 had left, and thanks to my friend, Mr. N. Micklewood, who remained some 

 davs longer, and who (although not an entomologist) was good enough to 

 continue to practise my methods, eleven more examples were taken. In 

 addition to the C. attaphilus Bris. in question (recorded in Ent. Mo. Mag. 

 1921, p. 100), the various species of Trachyphloeus mentioned above, as well 

 as Caenopsis waltoni Boh., were taken in numbers in the traps. There also 

 occurred *Pselaphus dresdetisis Herbst (1), and Stenichmts jmsUlns Miill. (2), as 

 well as many other species of Coleoptera. It is perhaps worth noting that 

 C'teniopus sulphureus L. was flying about in numbers and had the habit of 

 settling on the back of our necks whilst we were kneeling and making their 

 presence rather unpleasant by nibbling our skins with their mandibles 

 Species marked with an asterisk are apparently new to the County List. —

Halijjlus obliquus Er. infested tvith acarid parasites. — It is generally known 

 that the aquatic bugs { Cor ixa, Notonecta, etc.) are not infrequently infested 

 with acarid parasites ; apparently definite examples are lacking amongst the 

 beetles. A specimen of ILdiplns obliquus Er. was taken on August 28th, 1921, 

 at the Madingley Pools, near Cambridge, infested with two larval acarid para- 

 sites. One of these is attached to the wing, and the other to the dorsal surface 

 of the abdomen. Dr. D. Keilin, of the Quick Laboratory, has very kindly 

 examined the specimens, and informs me that they are larval Hydrachnids. 

 He considers that it is worth putting on record. — E. .1. Pearce, The Lodge,

Authotiotnus cinctus Kollar in Kent. — Having seen the report of Mr. Ilar- 

 wood's interesting capture at Darenth of ^. cinctus, recorded in this Magazine 

 for October last (vol. Ivii, p. 226), I enquired of Miss Worsley, who is doing 

 some interesting work from an economic point of view at Mailing on the 

 " Apple-blossom Weevil," whether she had found any weevils differing in any 

 particulars from the majority of those she was finding, and I was much 

 interested to receive from her a description of a single specimen she had 

 taken which apparently differed from the others. Unfortunately she 

 had not preserved it, but on December 15th I received from her two other 

 examples which I suspected might be A. cinctus. Mr, Harwood has very 

 kindly examined one of these and has identified it as Anthonomus cinctus. —
