in July lOi'O). The larva protects itself from attack by erecting its abilouiinal 

 brushes of hairs, aud vibratiug its long tail hairs. It changes to a pupa inside 

 the larval skin, the latter remaining partly open down the back. Joy says it 

 makes its own webbed cocoon ; a fact not mentioned by any other observer. 

 The pupal state lasts about a fortnight, and the perfect insect remains inside 

 the larval skin till mature. Tiresias serra appenrs to be widely distributed in 

 England, though Cumberland is its most northern record, and it has not been 

 found in Scotland or Ireland.

Coninomus constrictus Gijll. and other Coleontera ivith Ac<intho}iii/o/is 

 (Lnsiics) fttlit/inosd Latr. — I have recently taken one or two specimens uf a 

 Cuiiinoinus in the debris of a nest of the above-named ant, which agree iu all 

 respects with the description of C. constrictus Gyll. in Col, British Islands, 

 vol. iii, pp. 281-2. Their more feebly carinate elytra iind clear testaceous colour 

 give them an appearance very distinct from that of C. cari'natns Gyll., of 

 which 1 have examples from Woking, Guildford, and the New Forest. 



The nest of D.fuliyindsa in which I found the Coninumus is one that has 

 been examined regularly by me for several years past, as it lies on the direct 

 route to in\' favourite collecting-ground at Tubney, Berks. Its entrance is 

 about four feet from the base of a large, partially decayed oak tree iu a greeu 

 lane between Cothill and Tubney ; and so many interesting Coleoptera have 

 resulted from the systematic examination of " traps " of drj' grass, leaves, etc., 

 in the nest itself, as well as in the runs of the ants round the foot of the tree, 

 that I am induced to give a complete list of the species observed by me in and
