Genus Scolopocryptops .Newport 



This (;rniis, riprcscnted l\v only tlinc or four known species, is represented 

 in the fauna* of Cliina and of North and Soutli America. 



The ffenus is very close to Otocryptops in nearly all important structural ehar- 

 aeters, but differs in having eleven pairs of spiracles instead of the ten of the 

 latter genus, the thirteenth Kxly segment bearing the extra pair. 



One sjjccies is at present ktiowii frmii North .\inerica. 



Scolopocryptops miersii Newport 

 F.xtremely vari.ible in color. .Most .ulults dark brownish black; legs yellow, 

 the last pairs and the antenna' ])roxinially mingled bluish green and yellow. 

 The three proximal articles of the anteniiie smooth and shining. Prosternuni 

 with angle at each side more or less produced into a tooth-like process. Femur 

 of prehensorial feet be.-iring on mesal surface a rather large and stout basal tooth 

 which at its base is one-sixth as wide as the femur. Ventral plates without me- 

 dian furrow. Legs nearly glabrous. I-egs back as far as the nineteenth pair 

 with two tibial and one tarsal spine, most claws unarmed at base. Prcfemur of 

 anal legs with a stout s|)ine beneath and a smaller one within. Length up to 

 100 nun. or more. 

 , Doubtfully reeo;-d<d from California. How ever, it is widespread in th e 

 , southi-.'istir n st;iti-s .-nKl through Mexico, southw.ird to Brazil, and it is naturally 

 to be exjiected within this state. 



(ieiui.-^ Anethops Cliambcrlin 

 The species listed below is the only representative of this genus known : 

 Pairs of legs twenty-one. Spiracles ten pairs. Sterna with a median fur- 

 row in some, crossed by a transverse impression. Antenna" comi)osed of sev- 

 enteen articles, thickened |)roximally. Processes of pseudopleura- ending in a 

 single spine. Tarsi of all legs excepting the last ones unsegmented. Claw of 

 anal legs not of unusual size, armed at base with spines. 



Anethops occidentalis Cliambcrlin 



Ferruginous, feet i);ile. Most ventr.il plates with a cruciform impression, 

 the longitudin.'il furrow deejiest. Prosternum without dental plate. Tooth on 

 femur of prehensorial feet small, acute. Length ad 35 mm. 



Known onlv from ty])e si)eeinien taken in San Ciabriel canyon, Los Angeles 

 county. 



Genus Cryptops Leach 



A cosmopolitan genus represented by more than two dozen known species, 

 some of which range farther north than any others of the Scolopendroidea. 



Pairs of legs twenty-one. Pairs of spiracles nine. Antenna normally with 

 seventeen articles, the nmnber sometimes less. Dorsal scuta with two longitudi- 

 nal furrows and often also a median keel. Sterna with distinct cruciform im- 

 pressions. Prosternum without anterior extensions and with no dental plates.
