Insects. 1237 



Capture of Coleoptera in the North of England. 



Dromius fasciatus. Inhabits the sand-banks on the sea-coast near Whitby, where I 

 met with it in September last. My friend Mr. Hardy took it last year in Berwickshire, 

 by sweeping the herbage. 



Clivina collaris. I found this insect rather abundant beneath stones, by the Irthing 

 side in Cumberland, last June ; many of the specimens have the dark patch on 

 the elytra as figured by Curtis. I also occasionally pick up a stray specimen on the 

 banks of the Tyne. 



Helobia nivalis. This species I find in great abundance beneath stones close to the 

 Derwent-edge ; I also found it equally abundant in similar situations by the Irthing 

 in June. In common with many of the Peiyphi, it does not hesitate, but plunges into 

 the water when hard-pressed, swimming with considerable ease, but more frequently 

 concealing itself beneath the surface. 



Anchomenus oblongus. I took a few specimens under the bark of willows in winter ; 

 Mr. Hardy finds it in abundance beneath moss in damp woods, in spring. 



Plalyderus ruficollis. With us a rare and very local species ; I met with it on the 

 coast near South Shields early in spring, inhabiting a patch of loose stones, and scags 

 only a few yards in length. 



Blemus paludosus. I have this season picked up at various times some half-dozen 

 or so of this species, all of which differ a good deal from Mr. Stephens' description, 

 being generally of a much paler hue, perhaps the result of immaturity ? 



Ocys melanocephalus. Sparingly during the winter months in rotten willow stumps. 



Peryphus concinnus. This species has only occurred on the banks of the Tyne. In 

 1844 I met with it in some abundance beneath large stones on a shelving bank of 

 about a dozen yards in length. This season I again found it in the same place, but in 

 greatly diminished numbers. 



Peryphus saxatilis. In abundance both by the Tyne and Derwent-side, being found 

 early in spring and throughout the summer : it prefers hot sunny banks and lurks be- 

 neath the small gravelly stones common in such localities. I have taken many 

 examples of an insect similar in shape. It is, however larger, has pale legs, and the 

 elytra are suffused with reddish-brown, more or less tinged with bluish-green. 



Peryphus lunatus. A large and conspicuous species, captured on the banks of the 

 Irthing in June last. This species does not lurk so much under stones as many of its 

 congeners. I found them running about with much briskness in damp, shady places 

 contiguous to the river. 



Peryphus decorus P I received an abundance of this insect from Boldon in the sum- 

 mer of 1844, but have not since fallen in with it. 



Peryphus vividiameus. Occasionally met with by the Ouse and Tyne; I found 

 it rather common by the Derwent in June. It frequents the same locality as Bembi- 

 dium paludosum. (Zool. 1093). 



Peryphus cnemerythrus. Found in great abundance in the bed of almost every river 

 or brook that I have searched, many of the smaller specimens are truly beautiful, being 

 tinted with various shades of green, blue, and black. Its habitat is near the water-edge, 

 indeed much nearer than any other species that I have noticed ; it also displays much 

 less hesitation in plunging into that element. 



Peryphus agilis. A scarce species with us, I do not remember having captured 

 more than three or four individuals. It seems to be more abundant farther north, as 

 Mr. Hardy took a great many specimens in Berwickshire.
