straight, tüiichiiig the anterior shield, moreover its edges form 

 an uubr(jkeu curved line, rounded posteriorly. P e r i t r e- 

 m a t i c shields visible before the shoulders, nearly touch- 

 ing the anterior shield. To the sides of both the shields and 

 behind the posterior one an unprotected margin which is widest 

 posteriorly. All the dorsal hairs are more or less stiff 

 bristles, standing on the usual places. The following are of 

 systematic value : a pair of vertical bristles, directed forward ; 

 a pair of long shoulder-bristles (one on each shoukler) ; a 

 pair on the dorsum a little before the level of the shoulder- 

 bristles ; a pair, far remote from each other, in the posterior 

 half of the anterior shield ; two pairs quite on the posterior 

 edge of the posterior shield. Moreover the third median pair 

 of the anterior shield is also somewhat stronger than the 

 others. On the unprotected margin behind the posterior shield 

 about 7 pairs of small bristles. Between and a little behind 

 the level of the second median pair of the anterior shield 

 there is a small depression in the skin. 



Ventral side. T r i t o s t e r n u ni (tig. 19) short, wide, 

 in its distal half suddenly narrower, halfway provided with a 

 pair of lateral transparent minute triangular wings, and distally 

 with a pair of lateral transpaient large pointed slips. Laci- 

 niae more or less Hat, laterally hairy ; no demarcation between 

 them and the main trunk; so they proove to be mere prolon- 

 gations of the latter ; tirst a little diverging, then suddenly 

 converging, so that they leave a narrow oval cleft between 

 them before they diverge almost about their whole length ; 

 not reaching hairs 111 of the underside of the capitulum. — 

 J u g u 1 a r shields (tig, 1(3) small, more or less nail- or 

 Y-shaped. S t e r n o - m e t a s t e r n a 1 shield long, with 

 a less chitinized anterior margin, with nearly parallel sides 

 between coxae II, and ending pointed between coxae IV. 

 Anal shield pear-shaped, normal in size. Inguinal
