110 Psyche [August 



side just in front of the transverse suture; two short spines fol- 

 lowed by a long curved spine on each side at the inner edge of the 

 chitinized area along the temporal margins. 



Ventral side of the head with a narrow, irregularly shaped, 

 chitinous area on each side extending from the anterior margin past 

 the posterior margin of the antennae. Immediately behind this 

 area is a pair of small tooth-like projections followed by 

 another chitinized area with three broad teeth on its posterior 

 margin. No spines on the ventral side of the head. 



Antennae, five-jointed, the first joint quite broad the second 

 longer and more slender. On the ventral side the first joint bears 

 a series of four stout, hook-like projections and the proximal an- 

 terior angle of the third and fourth segments is produced into a 

 short tooth. 



Thorax about twice as broad as the head and somewhat shorter 

 and with the lateral margins strongly convex. Posterior margin 

 of the mesothorax with a short spine on each side just within the 

 spiracle and a longer spine near the meson. Sternal plate very 

 broad, the coxae of each pair widely separated. First and second 

 pairs of legs subequal, very small and weak and with small slender 

 claws. Third pair very large and stout and quite short. All 

 coxae bearing a spine near the posterior margin, the spines on the 

 posterior coxae being large and conspicuous. 



Abdomen elongated, broadest across the second segment, 

 thence tapering gradually to a rounded point. Each tergite witt 

 single chitinized plate and a single transverse row of spines. First 

 segment very small and with two small spines near the meson. 

 Second segment with a single large spine near each outer margin 

 and a group of four small spines on the posterior margin. Third 

 and fourth segments each with a similar group of four spines. 

 Fifth to eighth segments each with two spines near meson. 

 Pleural plates either lacking or reduced to extr^^mely small chiti- 

 nized areas, which on the second to fifth segments bear a pair of 

 extremely long, stout, sharp spines. Lateral margins of seventh 

 segment with two hairs one of which is about twice as long as the 

 other. Eighth segment with a pair of long hairs on lateral margins. 



Sternites likewise undivided, the third to sixth with a distinct 

 chitinized plate, the posterior lateral angle of which is produced 

 into a sharp, knife-like process. Second and sixth segments each
