Family PHILANTHID^: 



These fossorial wasps can always be easily distinguished from 

 any of the other groups of this divisiou by the deep constrictions 

 round each segment of the abdomen. They are generally black, 

 with dense punctures all over them, and some are marked with 

 yellow bands and spots. All our species come under the genus 

 Cerceris, Latreille ; and with the exception of one described by 

 Saussure in the " Reise Novara," have been worked up by Smith 

 in the British Museum Catalogue, Part iv. (1856), and in the 

 Annals and Magazine of Natural History for 1873.
