90 MR. C. J^C. POOL ON 



on the sides of the thorax and elytra. Head with eyes nearly as 

 broad as the thorax, finely punctured and pubescent. Thorax 

 and elytra coarsely but evenly punctured. There is an im- 

 punctate line behind the middle of thorax equal in width to the 

 space occupied by two of the surrounding punctures. Antennae 

 testaceous ; clubs slightly darker. Legs red. Tibiae short and 

 stout. 



Length l|-2g mm. 



This species comes near to C. alni, with which it has been 

 confounded in collections. The longer pubescence, coarser 

 punctation, as well as its shorter and stouter tibia?, will easily 

 distinguish it from that species. 



I have recently taken two specimens from rotten beech to 

 which is attached a small brown fungus containing Cis larva?, 

 collected with other fungi at Lyndhurst in September 1916. 

 There is a specimen in the Power Collection from the New 

 Forest, and another in the Wa.terhouse Collection taken in the 

 same locality by Mr. Kemp. Another example without data is 

 in the collection of Mr. H. Willoughby Ellis. It was along 

 with some common New Forest species, so is probably from 

 that district. 



C. PUNCTULATUS Gyll. 



This is now the only undoubted British species of Cis which 

 has not been recorded from the south of England. Orton Woods, 

 nr. Carlisle (Day & Britten). 



Scotland : Braemar, Aviemore, Nethy Bridge, Balmuto, Ran- 

 noch and Peebles. Professor Beare tells me the species lives in a 

 white fungus which develops between the wood and the bark of 

 dead Scotch fir. 



Not recorded from Ireland. 



C. oblongus Mell. =pygmceiis Marsh. 



Forest Hill, Dulwich, Horsell, Coombe Wood, Tonbridge, 

 Windsor, Reading ; Knowle, Warwickshire. 



I have bred it in profusion from fungi gathered from oak posts, 

 at Sandown and Brading, I. of Wight. 



Chatham (J. J. Walker), Oxford (Collins), North Holt, Mid- 

 dlesex (W. E. Sharp), Brockenhurst (Dr. Sharp), Enfield and 

 Epping Forest (Pool), Harlech (Donisthorpe). Exminster, June 

 1909. Abundant on old posts, Bovey (P. de la Garde). 



Not recorded from Scotland or Ireland. 



I have never found it accompanied by any other species of Cis 

 and have never seen the imago alive in winter. It is an active 

 creature in June and July, when I have seen it in numbers 

 running in hot sunshine upon posts and tree-trunks infested 

 with the fungus in which it feeds.
