Type, Arrli'mes Janguidus, Grjl. 



Head exserted; tlie eyes large, sublateral, oval and very convex. 

 Rostrum deflected, about as long as the head and continuous with 

 it, narrowed from tlie base to the middle, the base much broader 

 than the forehead, the apical emargination broad, the epistome not 

 carinate, the upper surface plane ; the scrobes apical, sublateral, 

 short and narrow ; mandibles as in Mylloceriis, but with the scar 

 rather more prominent ; mentum with 6 or 8 setae. Antemioi 

 subapical; the scape slender, almost straight, clavate and reaching 

 the anterior margin of the thorax ; the f unicle with the two basal 

 joints elongate, 1 evidently longer than 2, 3-7 subequal ; the club 

 elongate, 4-jointed, joint 1 scarcely longer than 2. Prothorax 

 slightly transverse, rounded at the sides, truncate at the base and 

 apex, the latter being narrower, the gular margin scarcely sinuate. 

 Scatellum distinct, longitudinal. Ehjtra subtruncate at the base, 

 much broader than the thorax at the shoulders, which are roundly 

 rectangular, more or less compressed behind, so that the sutural 

 margin forms a ridge on the declivity, with 10 striae, the lateral 

 margins distinctly sinuate above the hind coxas. Sternum with 

 the very large anterior coxae almost touching the front margin of 

 the prosteruum ; meso- and metastei'num and the abdomen as in 

 Mlilloceras. Legs slender, the femora strongly clavate and with 

 or without any tooth, the tibiae almost straight and simple, the 

 hind corbels open and terminal ; the tarsi slender, joint 1 the 

 longest, 2 narrow, 3 broadly lobate, 4 elongate, the claws long 

 and free. 



Range. India, Burma and southwards to Java. 



In all the species that I have seen the scales on the sternum 

 and venter are all delicately feathered.
