consisting of one segment,^ very much widened behind and with

 but contracted to a point laterally; second somewhat shorter and 



1 There is some doubt in my mind as to whether I have interpreted correctly the segmentation 

 of the body. Shelford has considered the thorax of iEnigmatistes as consisting of three seg-
