CANCROIDEA. 217 



cuius antennarum extemarum primus eo CMorodii brevior, ad pro- 

 cession oblongum frontalem attingens tantum. Articulus maxillipedin 

 externi ?>tius paido transversus, subrectangulatus. 



Resembling Pilumnus in general form, and near Chloroclius in feet 

 and antennae. First joint of outer antennae shorter than in Chloro- 

 dius, and just reaching to an oblong process of the front. Third 

 joint of the outer maxillipeds somewhat transverse, subrectangular. 



Although the species have the spoon-shaped fingers of Chlorodius, 

 in form they are usually narrower, much like Pilumnus, and one 

 species of Chlorodius here included has been named G pilumnoides, by 

 Adams and White, in allusion to this resemblance. In Pilodius, the 

 process that reaches from the front or its under surface to the first 

 joint of the outer antennae, passing just inside of these antennae, is 

 oblong and narrow, while in Chlorodius it is broader than long; more- 

 over, in the former, the joint, although soldered to the front, does not 

 reach so high up in the orbital fissure; moreover, in Pilodius this pro- 

 cess seems but a bending down of the outer edge of the front itself, 

 while in Chlorodius the process is usually from the nnder surface of 

 the front. This is the same distinction that exists between Xanthq 

 and Xanthodes. The body is usually thicker at the sides than in 

 Chlorodius, and the latero-posterior margin is somewhat less oblique. 



Pilodius pubescens. 



C. pilumnoidi similis. Carapax breviter pubescens, anticd leviter areo- 

 latus, margine antero-laterali simplicissimh 5-dentato, dentibus tenui- 

 bus, acutis. Pedes antici validi, minute tuberculosi et pubescenies, 

 digitis subspiiiulosis, brachio antici dentigero. Pedes 8 postici jjilosi, 

 articulo tertio supra spinuloso. 



Near G. pilumnoides. Carapax short pubescent, faint areolate ante- 

 riorly, antero-lateral margin simply five-toothed, teeth slender acute. 

 Anterior feet stout, small tuberculous and pubescent, fingers sub- 

 spinulous, arm with two or three prominent teeth on the anterior 

 margin. Posterior eight feet pilose, third joint spinulous above.
