452 CLAUDE FULLER. 



Mandibles black, faintly tinged with maliogany-red, bases 

 reddisli ; straight, comparatively slender, right the stouter, 

 both equally long, with incurved points and with very con- 

 spicuous, shoi't, caudo-lateral shoulders. Left mandible with 

 two teeth upon distal half and two proximal to these, the pairs 

 being separated by an acute incision ; below the lower pair 

 an acute basal process ; the distal tooth is lobe-like and con- 

 stricted at its base, the second formed like a cleaver, with a 

 bicurvate blade, the third convex, the fourth blunt, conical 

 and more salient than any; fourth separated from the third 

 by a shallow concave incision; margin below fourth incurvate 

 and deeply incised distal to the process. Right with two 

 teeth on proximal half ; below the second tooth a sharp 

 incision, the base then broadening; the distal tooth is 

 cleaver-shaped with a blunt conical apex and bi-curvate 

 blade ; the second cleaver-shaped and with both margins 

 bi-curvate. 



Anteunte 12 to 13 joints; arising from below a con- 

 spicuous hood ; short; IV and onwards moniliform ; charac- 

 terised by the long highly chitinised clavate joint III and 

 the erratic fusion of more distal joints; II a little longer than 

 wide ; III twice the length of II and clavate ; apical joint 

 oval. 



Gula with free apex very much broader and shorter than 

 inserted portion, with a rounded apex and tri-curvate, sub- 

 parallel sides. Inserted portion elongate narro-w ; caudal 

 extremity narrow; sides at first parallel and then diverging 

 outward ; not constricted as in Hodotermes. 



Thorax. — Sordid yellow-brown; much arched, with 

 margins of pro-, meso-, and metanotum much deflected and 

 introse. 



Pronotum large ; broader than head ; cephalic margin 

 incurvate Avith a very faint median notch ; sides curvate, 

 caudal margin broadly curvate; with paired elongate pyri- 

 form dark brown spots in cephalo-lateral corners, which are 

 connected by a wavy ti-ansverse furrow imuiediately posterior 

 to cephalic margin.
