62 IIBTEROMERA. [ 'scJinomcra 



punctured, antennae long, dark, with the under-side of the first two joints 

 yellow, base of palpi yellow ; thorax about as long as broad, slightly 

 cordiform, with sides rounded and widened before middle, and contracted 

 behind, closely punctured towards base, less closely in front ; scutellum 

 impressed ; elytra very closely and somewhat rugosely punctured, with 

 three entire raised lines on each. L. 7-8 mm. 



Male with the last joint of the maxillary palpi longer and the 

 pygidium more elongate than in female. 



In rotten wood of ivy, willow, elm, &c. ; occasionally by sweeping herbage ; I have 

 found it on a road and about an old wall ; local, and rather scarce, but somewhat 

 widely distributed ; London district, not uncommon, Hammersmith, Greenwich, 

 Darenth Wood, Belvedere, Faversham, Esher, Richmond, Sheerness, Chatham, Whit- 

 stable; Norfolk; Suffolk; New Forest (in numbers) ; Qlanvilles Wootton ; Whitsand 

 Bay, Plymouth ; Fordlands, Devon, on Uinhellifarae ; Swansea ; Leamington ; Rcpton, 

 Burton-on-Trent (one or two specimens) ; I know of no locality further north. 



I. sang-uinicollis, F. More elongate and duller than the preceding, 

 from which it may be at once distinguished by the colour of the thorax, 

 which is bright reddish-testaceous ; antennae dark or partly ferruginous, 

 with the under-side of the basal joints reddish-yellow ; thorax subcordi- 

 form, with strong impressions, closoly punctured, dilated a little before 

 middle and narrowed behind; scutellum rather large, very closely punc- 

 tured; elytra dull sage-green, clothed with greyish pubescence, with 

 three entire raised lines ; legs rather long, dark. L. 8-10 mm. 



On flowers and in decayed trees ; rare ; Coombe Wood (Stephens) ; Richmond 

 Park (Turner) ; Windsor Forest, on hawthorn blossom in May (S. Stevens) ; New 

 Forest and Bristol (Stephens); Sherwood Forest, on mountaiu-ash flowers (Blatch) ; 

 Ireland (Stephens).* 



This is a very small family, containing only about half-a-dozen genera 

 and twenty species, which are found with one or two exceptions in 

 Europe, Northern Asia, and North America ; two genera, Pyrochroa and 

 Dendroides, occur in Europe ; the former of these is represented in Britain 

 by three conspicuous species,. one of which is very common, and is well 

 known to the most casual observers of insects ; they are easily distin- 

 guished by their size and colour and very elegant serrate or pectinate 

 antennae; the head is exserted, horizontal or almost horizontal, strongly 

 constricted a short distance behind the eyes, which are emarginate ; 

 antennae 11-jointed, inserted before eyes; thorax narrower at base than 

 elytra, with the sides not margined ; anterior coxal cavities broadly open 

 behind and confluent, prosternum long before the anterior coxae, which 

 are furnished with a distinct trochantin ; metasternum long, with narrow 

 side pieces ; elytra wider than abdomen, rounded at apex ; abdomen with 

 five free ventral segments, a sixth visible in the male ; legs long, penul- 

 timate joint bilobed, claws simple. 



* Mr.W. F.Blandford has quite recently (June, 1890) taken a single specimen on haw - 

 thorn blossom in the New Forest, where it had not occurred for many years previously.
