(Plate xiv., Hgs. 5-7, tio-. -J-J ; with Figs. 28-25.) 



J : length about 8S. ni/m ; bi'eadth 12.50 ni/m. 



$ : length from 21. to 83. m/m ; breadtli from 11 to 17 

 ni/m. 



Olive chestnut, darkened along the posterior margin of the 

 segments ; darker in females which are of a muddy brown. 



Head twice as broad as long ,• anterior margin almost 

 straight, feebly notched in the middle and with a small, blunt 

 tooth. Surface smooth, between the eyes with rare, coarse 

 punctures, rugose along the upper lip ; each puncture furnished 

 with setse. Antennal fossa open in front and below, closed 

 above and behind by a strong ridge. Eyes composed of about 

 thirty-two larger and smaller ocelli congregated on a rounded 

 field; besides an isolated ocellus is seen standing somewhat 

 apart, near and below the Tomosvary organ which is dot-like. 

 Antennfe very short, scarcely longer than the first tergite in 

 the middle, "tapering endwards ; sixth joint sub-cylindrical, 

 more slender than any of the preceding joints ; last joint 

 tipped with four sensory cones. Micrometrical measurements 

 of the joints : 1st, 0-430 m/m ; 2nd, 0-473 m/m ; 3rd, 0387 

 m/m ; 4th, O'SOl m/m ; 5th, 0-473 m/m ; 6th, 0-774 m/m ; 

 7th and 8th, 0-086 m/m ; total length 2-924 m/m. Diameter 

 of first joint, 0-397 m/m ; of 6th joint, 0-279 m/m. 



First tergite not quite as broad as the head ; length 2.236 

 m/m, breadth 5.504 m/m. Anterior margin feebly sinuate ; 

 posterior margin rounded, the curve being more flattened in 

 the middle than on each side. 



Integuments of the following segments leathery, more dis- 

 tinctly so on the keels than dorsal ly ; keels of the second 

 segments rounded with a pad-like margiii ; centre of the keel
