BY CHARLES H. BOLLMAN. 



Ill this paper I have given the synonymy of the various species and 

 , analytical keys whereby they may be determined. 



As numerous attempts have been made to divide this family into 

 smaller groups, I have given keys for all the subfamilies and genera 

 known to date. 



Family SCOLOPENDBLDiE. 



1844. — Scolopendridce Newport. Trans. Linn. Soc, 275 and 374. 



The Scolopendridse are Ohilopoda belonging to the order Epimorpha 

 and are characterized by having 21-23 pairs of legs, 17-33-jointed 

 antennae, 9, 10, or 19 pairs of spiracles, and the pleurae of anal pair of 

 legs scutelliform. 



They may be divided into the following subfamilies : 



a. Pairs of legs 21. 



b. Tarsi, except that of anal pair, biarticulate ; pairs of spiracles 19; ocelli absent. 



Plutoniin/E . — I. 

 bb. Tarsi, except that of penultimate and anal pairs, biarticulate; pairs of spiracles 



10 ; ocelli absent or single Cryptopisle. — II. 



bbb. Tarsi of all the legs triarticulate ; pairs of spiracles 9 or 10; ocelli 4. 



SCOLOPENDRIN.E. — III. 



aa. Pairs of legs 23; tarsi, except that of anal and penultimate pairs, biarticulate; 

 pairs of spiracles 10 ; ocelli absent or 4 Scolopendropsin^e. — IV. 



Subfamily I. — Plutoniin^. 



188L — Scolopendridce plus iostigmi Cavanna. Bull. Ent. Ital., 176. 

 This subfamily only includes the European genus Plutonium. 



Subfamily II. — Oeyptopin^e. 



1844. — Scolopendrince Newport. Trans. Linn. Soc, 378 (in part). 



1847 .— Scolopendr ides morsicantes G-ervais. Apteres, iv, 243 and 250 



(in part). 

 1881. — Cryptopsii Kohlrausch. Archiv f. Naturg. 



Analysis of genera of Cryptopince. 



a. Last dorsal plate normal ; anal pair of legs not crassate. 



b. Ocelli absent „ Cryptops. — I. 



bb. Ocelli present, single '. : Eremops.* 



aa. Last dorsal plate twice as large as the preceding; anal pair of legs short and 

 thick ; ocelli absent TheaTops. — II. 



* Eremops nom. gen. nov. for Monops Gervais, which ispreoccupied. Deriv. : ep^uof, 

 lonely; uip, an eye.
