GO Mr. Arthur M. Lea's Revision of the 



thickness towards the base, but all are subject to variation. 

 In many specimens the only costa distinctly elevated above 

 the others beyond the middle is the true fourth ; frequently 

 the smaller costae (first, third and fifth) become very 

 irregular and tend to disappear towards the apex, so that 

 sometimes two rows of punctures become conjoined into 

 one irregular row ; two costae also sometimes become con- 

 joined and narrowly connected with the apex ; but towards 

 the apex all the costae become irregular, and they are 

 seldom exactly the same on both elytra. 



The colour of the elytra varies slightly in living speci- 

 mens, and is subject to alteration after death ; the claws 

 (or at least their tips) are invariably reddish. 



The size varies from 9 to 21 mm., the male usually 

 being smaller than the female, but the largest specimen 

 before me is a male. 



The brief description here given will enable this species 

 to be distinguished from all others known to me. 



Black ; elytra reddish. 



Rostrum long and thin. Antennae pectinate in the male, serrate 

 in the female, 3rd joint distinctly longer than the 4th. Prothorax 

 7-areolate. Elytra quadricostate, the interstices each with two 

 double rows of punctures. 



This will include hosts of forms all differing to a certain 

 extent in the lengths and shapes of the antennal joints, 

 in the shapes and comparative lengths of the rami, in the 

 proportional size and width of the prothorax to the elytra, 

 in the size and shape of the elytral punctures, in the com- 

 parative size and terminations of the elytral costae, and in 

 the different shades of colour.
