DESCRIPTION OF A NEW FLEA — SKU8E. 79 



of Curtis, bub the absence of eyes, remarkable structure of the 

 head, and the elongate thorax in the female, seem to demand its 

 exclusion from known genera. 



Not the slightest trace of eyes could be detected in specimens 

 of the female, after repeated examinations under a |in. objective. 

 Their rightful position is occupied by a bristly hair, In my 

 opinion the female anchors herself by the spiny corona, and is 

 perfectly blind.
