NOTES ON SOME YORKSHIRE COLEOPTERA. 
it. SEAINFORGH, B-A., Bosc: 
AmonG the beetles I have taken in various parts of Yorkshire 
during recent years, are six species not included in the county 
list. The occurrence of some of these is of more than local 
interest. Five are from the East Riding and one from the 
North Riding, and two of them are estuarine forms. 
Noterus sparsus Marsh. (capricornis Herbst., clavicornis de 
G. teste Bedel).—On August 28th I paid a visit to the slightly 
brackish ponds on Saltend Common, near the Humber foreshore 
just to the east of Hull. They proved fairly rich in aquatic 
life, the Water Spider, Argyroneta aquatica, and the water 
beetles, Coelambus parallelogrammus, Agabus conspersus, Dytis- 
cus punctulatus, D. marginalis, Philydrus maritumus, and other 
insects occurring in more or less abundance. Among the 
smaller beetles collected were a number of species of Noterus 
which proved to be undoubtedly N. sparsus Marsh., the 
characters defined by Sharp,* viz., prosterno medio carinato in 
both sexes, and antennis ... . articulis 5° et 6° longitudine 
subaequalibus in the male, being clearly discerned. Further 
visits to Saltend during September and October proved that 
the beetle was very common there. 
Fowler} says he has ‘never found it in Derbyshire or 
Lincolnshire and can find no record further north.’ Since this 
was written it has been found in several localities in Lincoln- 
shire.{ The Hull district, however, is the northernmost recorded 
station of the species in Great Britain. Strictly speaking, 
this is perhaps hardly a new record for the Hull area, as the 
species was included in a list of beetles of the Hull district in 
1907,§ but without precise locality, and was possibly over- 
looked by the compilers of the Yorkshire list in the Victoria 
County History, or perhaps further confirmation of the record 
may have been considered desirable. As I have been unable 
to trace the specimen or specimens whereon this record was 
based, which, in the light of its re-discovery, was probably 
correct, it seems advisable to look upon the species as an addi- 
tion to the Yorkshire fauna. I have re-examined the Noterus- 
taken at Hornsea Mere and find that it is the remaining British 
species of the genus, viz., N. clavicornis de Geer (crassicornis 
Miill.).
