Mr. G. A. K. Marshall on 



of view, the resemblance being much less marked than in 

 the field, except perhaps Bccoptoptera which is a splendid 

 case, and it has caused me to hesitate more than once 

 before venturing to handle it. At the present time I 

 would not venture to express an opinion as to the use or 

 significance of the colours in this group. The Mutillidiv 

 of course are armed with a powerful sting, which however 

 they are slow to use, and besides they are very hard ; the 

 red prothorax is by no means conspicuous when they are 

 running on the ground, the abdomen being the part that 

 catches the eye, and when hard pressed this is elevated in 

 the air evidently as a warning. I have noticed that it is 

 very difficult to distinguish the pattern while the insect is 

 running, the general impression being merely that of a 

 black body with white spots. The same applies to the 

 CicindelidiB and Carabidx, which are all fast runners and 

 most of them very difficult to distinguish inter se in the 

 field at first siglit. The exact resemblance of Graphipterus 

 antioJcanus to Piezia selousi is marred by the shrinkage in 

 the former of the pygidium, which bears two white patches. 

 Atradonota, despite its markings, very much resembles 

 one of our larger black ants, especially in its manner of 

 running. A good many other species (especially of Clcridm) 

 might also be included in the group." 



The Mutilloid group of Coleoptera from Salisbury may 

 be arranged together with their models as follows, the 

 plan being that adopted in Plate XVTI, figs, 1-12 and
