7. Älloptes ditrichus (Oudms.) (Fig. 28 — 29.) 



1904, Nov. 1. Älloptes ditrichus nov. sp. Oudemans in Ent. Ber., 

 V. 1. no. 20. p. 195. 



Female (fig. 28). Length 360—368 /a. Width 120 bis 

 128 /<. — Colour dark brown. — Shape elongate with 

 parallel sides between legs II and III, than tapering with sinuous 

 sides backward , abdomen bilobate , legs shorter than the width 

 of the abdomen. — Textur e of the shields smooth ; of the 

 soft skin finely wrinkled. 



Dorsal side (fig. 28). Anterior dorsal shield longer 

 than wide , greatest width between the anterior lateral shields 



and slightly wider than the distance 

 between trochanteres II. There is 

 an indication of omoplatal shields II 

 in the form of two minute crescents 

 outside of the long prosomatic 

 hairs. Anterior lateral shields 

 usual, with rounded posterior widest 

 portion. Posterior dorsal shield 

 long, leaving a rather narrow band 

 of soft skin before it seif, more 

 than three and a half times longer 

 than wide , with straight anterior 

 edge and sinuate lateral edges, at 

 the level of caruncles IV reaching 

 the lateral edge of the abdomen. 

 Posterior lateral shields simulating 

 dorsal coxal plates III , though 

 somewhat remote from trochan- 

 teres III, trapezoidal, with inward 

 base. Hairs: The anterior pair 

 of long hairs are planted in the soft skin between the anterior 

 dorsal and the crescent shaped omoplatal shields II. Their ac- 

 companying smaller hairs, inside of them, are planted in the dorsal 

 shield. Moreover I discover only 2 pairs of minute pits (of 

 minute hairs most probably) in the lateral margin of the posterior 

 dorsal shield , there where the shield is widest , i. e. on a level 

 with femorigenu III and tarsus IV. 



Ventral side (fig. 29). Epimera I united to a sternum; 

 trunk and branches of the Y of equal length. Epimera II as 

 long as epimera I, almost straight. Epimera III semicircular (in 

 fact they are a combination of the primitive epimeron and the 

 chitinized distal margin of the original coxal plates III). Epimera IV
