364 Mr. H. Donisthorpe on 



Motor chus minor, L., and M. umbellatarum, L. 



These beetles have very short elytra and the true wings 

 are exposed. They much resemble Ichneumonidig. Mr. 

 Holland considers the former a mimic of a Mntilla. 



Rhagimn inquisitor, F., and R. indagator, Gyll. 



These species, like many other Longicornes, are coloured 

 in such a way as closely to resemble the appearance of 

 lichen on trees. The former is often found walking on 

 lichen-covered oak trunks. The latter, which in the 

 British Islands is only found in Scotland, is very hard to 

 find, as Professor Beare and I experienced at Rannoch. 

 It conceals itself in the crevices of weather-beaten fir 

 stumps. 



Rhagium bifasciatum, F. 



Of this beetle, which lives in fir and pine woods, Mr. 

 Holland says, " It closely resembles a flake of pine bark." 



Toxotus meridianus, Panz. 



This beetle, with its broad shoulders, spined thorax and 

 long straggling legs, looks at first sight more like a 

 Hymenopterous insect than a beetle. 



Pachyta cerambyciformis, Schr. 



This beetle, which is yellow spotted with black (character- 

 istic warning colours), flies rather like, and rather suggests 

 a wasp-like insect. 



Pachyta collaris, L. 



It is of a blue-black colour with a red thorax, and much 

 resembles the Phytophagous genus Lema. 



Anoplodera sexguttata, F. 



This beetle is black spotted with yellow (warning 

 colours). Mr. Holland considers it " wasp-like." 



Strangalia aurulenta, F., S. qttadrifasciata, L., and $ 

 armata, Herbst. 



These three species are all yellow striped with black 

 and look like wasps or other Hymenoptera. As before
