CAMBALOID MILLIPEDS^ — LOOMIS 57 



Family CAMBALOPSIDAE 



The members of this family differ most fundamentally from those 

 of the Cambalidae in the possession of an undivided mentum. The 

 family has hitherto been known only from southeastern Asia, but 

 the discovery of four new species in California greatly extends the 

 distribution, no forms being known as yet from the intervening 

 countries. Two new genera have been required for the inclusion of 

 these species in the classification system, the genus Eiidere having 

 eyes, recessed mandibulary stipes, and very strongly constricted neck 

 segments, in contrast to the genus Leiodere^ with its lack of eyes, con- 

 vex mandibulary stipes, and much less strongly constricted neck 

 segments, to mention only a few diagnostic points. 



ENDERE, new genus 



Type. — Endere disora^ new species, from California. 



Description. — Body slender, about 18 times as long as broad; dis- 

 tinctly moniliform and a little depressed, as seen in cross section. 



Head with ocelli in a single series covered by the anterior mar- 

 gin of segment 1. Antennae (fig. 18, a) short, subclavate, broadly 

 separated, inserted on the sides of the head rather than on the dorso- 

 lateral surface, the bases not exposed from above (fig. 18, 5). Clyp- 

 eus with six setae. Labrum depressed below the level of the clypeus, 

 tridentate, with sixteen short setae across base. Gnathochilariimi 

 (fig. 18, c) with mentum entire, nearly as long as the stipes, the up- 

 per fourth decidedly attenuated and reaching to near the tips of 

 the lingual laminae, median surface with a rounded depression 

 deepening behind ; stipes without a distinct outer angle, the sides con- 

 tinuous, broadly and evenly rounded from the outer papillate process 

 to the base ; lingual laminae slender, about half as long as the stipes. 

 Mandibulary stipes inconspicuous beneath the lateral margin of the 

 head, the surface distinctly depressed to receive the antennae ; lower 

 margin with a raised rim. 



Segment 1 broad and longer than the next three segments com- 

 bined; anterior corners prominent, produced forward, broadly 

 rounded; posterior corners nearly right-angled, produced backward 

 slightly and strongly curved under the body ; lateral margin descend- 

 ing obliquely from in front to just behind the middle, where it bends 

 upward, forming an obtuse rounded angle, margin with a faint rim ; 

 lateral surface without striations. Head and first five segments 

 shown in lateral view in figure 18, d. 



Segments 2, 3, and 4 flattened, scarcely convex, lacking the trans- 

 verse constrictions of the succeeding segments, the sides rapidly
