or contiguous, except sometimes in exuviae; sides of 

 10 subparallel, largely embraced by the lateral spines 

 of the rapidly narrowing 9th segment. 

 cc. Third antennal joint flat, subcircular or broad oval, 

 less than twice as long as broad. 

 dd. Body very broad, 3d antennal joint subcircular, 

 abdomen much flattened and subcircular, with 

 distinct dorsal hooks; middle legs more distant 

 at base than fore legs; lateral labial lobes ob- 

 scurely denticulate, with broadly rounded apices. 



V. HageiiiKS. 



d. Body of the usual form, 3d antennal joint broad 



oval, dorsal hooks entirely wanting; middle and 



fore legs about equally distant; lateral labial 



lobes dentate, with blunt apices. VI. LantJms. 



c. Third antennal joint subcylindric, more than twice 



as long as thick; middle and fore legs about equally 



distant; lateral labial lobes toothed. 



ee. Dorsal hooks with short but acute spiny tips; 



median labial lobe slightly concave; lateral lobes 



with prominent apical hook. 



VII. Droni ogo mp h us. 



e. Dorsal hooks sometimes present, but obtusely 



pointed, usually absent except for a median tooth 

 in the hind margin of 9; median labial lobe more 

 or less convex, in some species nearly straight; 

 lateral lobes with a more or less evident apical 

 hook. VIII. GoiHphas. 



I. Aphylla Selys. 



ApJiylla prodncta Selys. 



Two curious nymphs from Florida are described by Hagen 

 as probably l)e longing to this tropical species, common in 

 Cuba. The unusual length of the last segment will at once
