gracilipes. 



KEY TO THE SPECIES OF THE GENUS PODOCHELA 



A'. Postorbital protuberance a large lobe. 



B'. Supraorbital margin armed with two long spines. Sternal segments of 

 male elevated, flat, closely and finely granulate. Manus of adult male 

 not inflated. Rostrum long, spiniform, arched upward. 



curvirostris, p. 50. 

 B^. Supraorbital margin armed with a series of spinules or small spines. Ster- 

 nal segments of male not closely and finely granulate. 

 C. Manus of adult male inflated, fingers widely gaping. Sternum of male 

 pubescent, not granulate nor laminate. No prominent lobe behind 

 and below postorbital lobe. (Rostrum in doubt, perhaps bilobed.) 



lobifrons, p. 57. 



C^. Manus of adult male not inflated, fingers contiguous. Sternum of male 



laminate, each lamina overlapping the one behind it; surface sparingly 



granulate with scattered, pointed granules. A prominent lobe behind 



and below postorbital lobe. Rostrum short, pointed. 



lamelligera, p. 52. 

 A^. Postorbital protuberance a granule, or wanting. 



B'. Rostrum long, ending in a spine. Manus inflated in male. 

 C^ Only one tubercle on first abdominal segment. 



D^. Rostrum very long, much more than half as long as postrostral portion 



of carapace latimanus, p. 56, 



D^. Rostrum less than half as long as postrostral portion of carapace. 

 E^ Size small (not over 13 mm. long). Gape between fingers of adult 

 male subtriangular, deep at proximal end. Neck long. Rostral 



spine slender gracilipes, p. 47. 



E^. Size large (up to 24 mm. long). Gape between fingers of adult 

 male suboval. Neck short. Rostral spine stouter, gradually 



tapering hemphillii, p. 49 



C^. Two median tubercles on first abdominal segment. Rostrum from three- 

 fifths to one-half as long as postrostral portion of carapace. 



barbarensis, p. 54. 

 W. Rostrum short, not ending in a spine. 



C Rostrum thin, hood-shaped, hollow beneath. 



Di. Rostrum somewhat triangular, widest at its origin. 



E'. A postorbital granule. Sternum of male not granulate. 



F^. Sternum and basal articles of legs not vermiculate. Gape 

 narrow between fingers of adult male. 

 G^ Dactyls of last three ambulatory legs curved, short, contained 

 twice, or more than twice, in their respective propodites. 



Cardiac prominence low riisei, p. 33. 



G^. Dactyls of last three legs less curved and longer, those of last 

 two pairs contained less than twice in their respective propo- 

 dites. Cardiac prominence higher and more acute or ending 



in a short spine sidneyi, p. 39. 



F2. Sternum and basal articles of legs vermiculate. Cardiac promi- 

 nence elongate, compressed. (Gape between fingers of adult 

 male not known.) vestita, p. 42.
