Disting^nished from C/ialcogonatopiis b\- havinj::: only five joints 

 to the maxillary palpi, two before and three beyond the genicula- 

 tion. 



Table of species of Agoiialof^iis. 



Pronotum with strong- constriction, dividing^" it into 

 two lobes, the posterior not compressed, cariniforni. 

 Lamellate denticles of fifth joint of front tarsi be- 

 neath not reaching back to the articular cavity. 

 Abdomen ferrugii^ous or testaceous. .A. pallidicoriiis. 

 Abdomen mostly black. ..-J. paUidicornis var. diibiosiis. 

 Lamellate denticles of front tarsi almost reaching the 

 articular cavity of the fifth joint beneath. 



Insect almost wholly ferruginous A. fcrnigiiiciis. 



Insect largely dark brown and black. ../. piccsccus. 

 Pronotum compressed into a median carina on the 

 posterior part, which is only fain.tly separated from 



the anterior ./. hctcrotJiorax. 



A. iiiiiitidiis was bred after the construction of this table, 

 where it would be placed with A. paUidicornis var. diibiosus, 

 from which the dull abdonu'u would at once sejjarate it.
