(joint?), supplemented by a spatulate hyaline portion. Maxillary 

 isternuni entire and distinct; maxillary palpus slender; claw simple; 

 basal joint subeijual in lengtli to the other two taken together. Pre- 

 hensorial sternum without chitinous lines. Pleuroe of the prehen- 

 sorial sternum divided by chitinous ridges into three areas. Sterna 

 with a median anteriorly bifurcate chitinous thickening. Ventral ])ores 

 wanting. Last sternum very short; last pleurte very large and long, 

 with numerous pigmented pores. Anal pores present; anal legs with- 

 out claws. Number of segments constant on both sexes of each si)ecies. 

 In most of these characters, the Dicellophilidje approach the Scolo-

 case with the mouth parts, the lack of ventral pores, the last segment, 

 and the constant number of segments.
