Psyche 



[August 



with the outer anterior angle of the tarsus produced into a distinct 

 point. 



Abdomen elongated with nearly parallel sides, entirely without 

 chitinized tergal and sternal plates, the derm having a reticulated 

 appearance. Each segment, except the first and second, with a 

 single transverse row of stout spines that are somewhat longer than 

 the segment. First and second segments apparently fused, the 

 first without spines. Second segment with six to eight spines. 

 Third to sixth segments with eighteen to twenty-two spines, all 

 spaced very closely. Seventh with about sixteen spines which 

 are for the most part longer and more slender than those on the 

 other segments, the second from the meson on each side being 

 especially long and slender, reaching beyond the end of the ab- 

 domen. Eighth segment with about twenty long, slender hairs. 

 On the ventral side the arrangement of the spines is in general 

 similar, except that the eighth segment bears no spines and the 

 ninth has a group of stout spines near each lateral margin. 



Six pairs of pleural plates present. The first 

 pair, which may be assigned to the second seg- 

 ment, is divided into two parts, one lying on 

 the dorsal side of the abdomen and the other 

 on the ventral side with three or four spines 

 in the space between. The dorsal piece is long, 

 somewhat broadened posteriorly, with the 

 inner posterior angle extended into a roundly 

 pointed process and bears a single very long 

 hair and an inconspicuous spine on the pos- 

 terior margin. The ventral piece is shorter, 

 somewhat broadened at the posterior end and 

 bears no spines. Plates of the third segment 

 appressed to the dorsum and partially over- 

 lapping the fourth segment; inner posterior 

 angle produced into a rounded tooth and a 

 single long hair on the posterior margin. Plates 

 of the fourth segment similar but smaller, pro- 

 jecting from the body wall and likewise bear- 

 Fig. 5. Fahren- ing a long stout hair. Plates of the fifth to 

 holzia trihulosa sp. seventh segments similar to those of the fourth 

 ]^Je but somewhat smaller and without hairs.
