2 34 SOME ADDITIONS, ETC., TO THE COLEOPTEBA 



L., various Rhizophagus, two ( $ and 5 ) Clinocara 

 undulata, Kr., Ccrylon ferriigineiiin, Steph., etc., were 

 also taken (Ento. Record, 1904, p. 260-2). 



Mr. Tomlin's identification of this species was 

 kindly verified by Mr. Donisthorpe : — Fagi is dis- 

 tinguished from C. histeroides in having shorter and 

 thicker antennae, basal impressions of thorax (in 

 histeroides transverse and rather shallow) longi- 

 tudinal and deep, and in comparison the thorax is 

 more strongly and sparingly punctured. 



*i68o. C. ferntgineum, Steph. {angt/shitin/i, Er.). 



Is, I think, the commonest species of this genus 

 we have in the Derwent Valley. I have taken it 

 beneath the bark of fallen oaks at Winlaton Mill, 

 Gibside, and Rowlands Gill, and one evening (April 

 28th, 1904) I took it in numbers from a rotten oak- 

 stump near Winlaton, many of the specimens evi- 

 dently freshly emerged. From the same stump I 

 captured several coleopterous larvae and pupae of 

 C. fei-riigineuni (?), but unfortunately they died 

 before reaching maturity. Thus it will be seen that 

 the whole of the genus Cerylon is found in our valley 

 (Ento, Record, 1904, p. 260-2). 



1686. Hister succicoia, Th. 



Not at all uncommon. 



1694. H. biviaculahis, L. 



Winlaton, spring, 1904. 



1730. Cere us bipustulatiis, Pk. 



From wild cherry blossom. May, 1904, Winlaton, 

 Winlaton Mill, etc. 



1736. Ep'urcea melina, Er. 



Occasionally from meadow sweet, July, 1902, and 

 from hawthorn blossom, June, 1904; Winlaton Mill. 

 "On flowers, but very rare" (N. H. Trans., 

 p. 56).
