Prchensorial feet without a tooth on mesal face of femur, claws large. Pseudo- 

 pleurae without caudal processes, merely rounded caudally. Legs without tibial 

 spines. Tibia and first tarsal joint of anal legs with a comb-like row of spines or 

 teeth on ventral surface. 



Cryptops hyalinus Say 



Fulvous, the legs and antennae paler. Very slender. Prosternal margin 

 with si.\ to eight fine, short hairs. Eighteenth sterna witii cross furrow only, 

 the nineteenth to twentv-first mostly un furrowed. Inner margin of pseudo- 

 pleura rounded, porigerous area with about seventeen large pores, the smooth 

 caudal border clothed only with scattered hairs. Spiracles small, circular. Pre- 

 femur of anal legs ventrally with numerous spiniform bristles, without apical 

 spiniform process ; femur similarly clothed, without apical tooth or process. 

 Tibia ventrally with seven to eight comb-teeth ; the first j oint of tarsus with 

 four, neither with lateral spines. Length 15-20 mm. 



Doubtfully recorded from California (Kraepelin). A vial, possibly, but not 

 certainly, from southern California (Catalina Island), and in the author's col- 

 lection, contains several specimens of this species. The species is widespread 

 in tlie eastern and southeastern United States. 



Genus Newportia Gervais 



Between fifteen and twenty' species of this genus are known, all from America 

 and all but one {N. utahensis Chamb.) from tropical or sub-tropical localities. 



In the members of this genus there are twenty-three pairs of legs and eleven 

 pairs of spiracles. First dorsal plate with a transverse cervical furrow. Ven- 

 tral plates with longitudinal furrows but with no cross impressions. Prester- 

 num with or without dental laminae. Femur of prehensorial feet without basal 

 tooth. PseudopleurEB with long, pointed caudal processes. Tarsi of anal legs 

 composed of numerous segments, lash-like. 



While no species of this genus has as yet been found within California, it 

 seems quite likely that the genus will be found to be represented in the southern 

 portion of the state. The species of the genus are obscure in habit and most of 

 them are known from one or from but few specimens. Hence, a species occur- 

 ring in a locality may long escape discovery. 



Family Scolopendridae 



The genera of this family known to occur within the United States may be 

 separated by means of the following key : 



Key to genera of the Scolopendridae 

 A. All legs lacking tarsal spines. 

 B. Process of pseudopleura three to many toothed or spined, slender, sub- 

 cylindric; no trace of basal jilatc. Genus Hemiscolopendra Kraepelin. 

 AA. All legs, excepting the anal, witli tarsal spines (cephalic plate with cau- 

 dal margin free). 

 B. Claw of anal legs and without basal spines; cephalic plate but slightly 

 overlapping the first dorsal. Genus Arthrorhabdinus Verhoeff.
