Subfamily XI. — Craspedosomin^e. 



Analysis of the genera of Craspedosominai. 



a. Lateral carina? large. 



b. Lateral carinas bent downwards; segments convex above, concave beneath. 



Rhiscosoma Latzel. 

 bb. Lateral carina? horizontal ; segments flat above, convex beneath. 



Atractosoma Fanzago. 

 aa. Lateral carina? absent or very weak ; setigerous tubercles well developed. 



Craspedosoma* Leach. 



Subfamily XII. — Oampodin^e. 



Analysis of the genera of Campodince. 



a. Dorsal plates marked with sharp narrow carina?; under parts deeply reticulated; 



lateral carina? distinct BranneriaI Bollman. 



aa. Dorsal plates never carinated; under parts lightly reticulated. 

 b. Anterior pair of legs of eighth segment of male 5-jointed. 

 c. Back not scaly; setigerous tubercles almost absent; segments almost cir- 

 cular; legs rather short; second article of eighth pair of legs of male 



stout, last armed with a claw Campodes J Kochl 



co. Back scaly, depressed ; setigerous tubercles ; legs long ; 



second article of eighth pair of legs of male slender, last not armed with 



a claw Pseudotremia Cope.

 cles well developed Scoterpes § Cope. 



Subfamily XIII. — Chordeumin^e. 

 Includes the European genus Ghordeuma Koch. 



Subfamily XIV. — Striariin^.

* Analysis of subgenera of Craspedosoma. 



a. Ocelli absent Haasia, subgen. nov. 



aa. Ocelli present ,.... Craspedosoma, s. str. 



Haasia is named in honor of Dr. Erich Haase, of Berlin, Germany. This subgenus 

 contains Grasp, troglodytes Latzel and Grasp, mamillatum Haase, both of which are 

 European species. 



fBranncria, gen. nov. Type: Craspedosoma carinatum Bollman. Ann. N.Y.Acad. 

 Nat. Sci., 108, 1888 (Mossy Creek, Term.). It is easily separated from its relatives 

 by the character of the dorsal plates and the large lateral carina?. I have put 

 it in this subfamily on the supposition that all the American genera belong here. 

 Named after Dr. J. C. Branner, State geologist of Arkansas.

b. Eighth pair of legs of male ending in a claw Scoterpes. 



bb. Eighth pair of legs of male not endiug in a claw Z vgonopus. 



aa. Ocelli present; eighth pair of legs of male not ending in a claw.
