CLASSIFICATION 



437 



As already stated, Simon does not consider the possession of 

 the two often very feebly developed eyes of generic importance, 

 and admits only the genus Chelifer. 



Five species of Chelifer (including Cli. cancroides) and five 

 of Chernes have been recorded in England.

Sub-Fam. 2. Garypinae. The Garypinae have the cephalo- 

 thorax greatly contracted in front and often projecting con- 

 siderably. 



There are three genera, C'kiridium, Olpii/m, and Gr///>i'x. 

 Chiridium is eyeless, and appears to have only ten segments in 

 the abdomen, the tergal plates of which are 

 Injected. C. museoram is found in England, 

 and is the only Chernetid except Chc!/j'<r 

 cancroides which habitually lives in houses. 

 C. ferum is found under bark in the south 

 of France. 



Neither Of/tin m nor (,'n, ///>//*, \\bicli both 

 possess four eyes and eleven abdominal seg- 

 ments, have as yet, been found in this country. 



Gan//>itx, like ('/i/rii/i inn, has the dorsal ab- l ''"'- Olpium 



, . . palhpes, enlarged, 



dominal plates bisected. Chere is a transverse (Aft.TSim..n.) 

 stria on the ceph.dol borax, and the eyes are 

 far from the anterior border. In Ol/ii/nn the dorsal plates are 

 undivided and the eyes more anterior. 



Sub-Fam. 3. Obisiinae. The eephalotlmrax of the (ibisiinae 

 does not narrow and Is, indeed, sometimes broadest anteriorly. 

 The chelicerae are notably large, and the dorsal abdominal plates 

 undivided. They are the most active of the Chernetidea ordinarily
