M. Bedel informs me that he knows of no exception to the rule 

 of two pores, and the specimens he sends me bear both. 1 have 

 already recorded an instance of the abnormal number of three pores 

 occurring in anthohia in the region of the scutellum, the additional 

 one being situated at the base of the sutural stria on one elytron. 



On the other hand, rare exceptions to the rule of no prescutellary 

 pores occur in lucida. I have seen one in about 120 examples 

 in which the insect bears one prescutellary pore. 



In familiaris exception to the rule of no prescutellary pores 

 proves extremely rare. I have come across none in 350 examples of 

 my own. Mr. Champion has kindly communicated to me a specimen 

 from his collection bearing two pores rather similar to those of 

 anthohia, but all the other characters of familiaris are present in this 

 insect. 



(6) Prominent eyes — marking out anthohia and lucida from 

 familiaris. 



There seems to be little or no variation in this character. 



(7) Thoracic fovece impunctate. — A character differentiating an- 

 thohia from familiaris and lucida. It is constant in all cases of 

 anthohia which have come to my notice. I observe, however, that 

 about 5 per cent, of familiaris may be impunctate also, and a slightly 

 larger percentage of lucida. 



(8) Margins of thorax. — In common with lucida, anthohia has 

 the anterior margin of the thorax straighter than familiaris, and 

 consequently the anterior angles less prominent. Marking it out from 

 both familiaris and lucida, anthohia has the sides of the thorax in 

 front straighter and the base contracted, whereas the thorax is 

 widest at the base in familiaris and lucida and contracted in front. 

 This character is somewhat variable. 



As a rule I think it is a comparatively easy matter to distinguish the 

 three species, but, should a combination of abnormal characters occur 

 in lucida which I have known to occur separately in that species, such 

 as the thoracic fovese impunctate, sides of the thorax at the base 

 slightly contracted, and in front not strongly narrowed, together 

 with the presence of a prescutellary pore, it might be difficult to 

 tell it from abnormal anthohia. 



I do not know how far the difference in the shade of the legs 

 would tell in the case of old specimens cleaned up. I have only 

 observed it in fresh examples. 



Since dealing, in the first part of this note, with the various
