OYCLOMMATUS. 65 



ill-(l(ifiiu'(l rcjiUKlish rlevaticjiis in the middle. The pronoluni 

 is stioiigly and closel}', and at the sides rugosely, punctured. 

 The front angles are rounded, tlie sides feebly curved to the 

 lateral angles, which are acute, and concave to the hind angles, 

 which are rather sharp. The scutellinn and the sutural edges 

 of the elytra are sluning. The elytra arc densely [junctured, 

 but rather less so towards the suture than at the sides. The 

 nientuMi is rugose, tlie inetasternuni bears rather scattered 

 ])uncturcs and th(^ abdomen is very closely [)unctured beneath. 

 The front tibid bears about three or four fairly strong lateral 

 teeth, the middle tibia, a strong lateral spine and the liind 

 tibia a very minute one. The seventh joint of the antenna 

 bears a short process. 



(J. Bright orange-yellow, with the mandibles, legs and lower 

 surfa(;e reddisii, the tibia^ and tarsi bearing conspicuous t)right 

 yellow fringes. The upper surface very smooth, the head and 

 sides of the pronotum micros(;opically granular and (jpaque, 

 the middle of the ])ronotum and the elytra shining. The front 

 angles of the head rather prominent and the sides straight and 

 l)arallel behind the eyes The head is rather hollowed in 

 front and the clypeal process is triangular. The pronotum is 

 short, with the front angles produced and rather sharp, the 

 sides almost straight to the lateral angle, which is spiniform, 

 and concave to the strongly marked hind angles. The antenna 

 and legs are very slender, the three club-joints of the former 

 fairly long and the seventh joint produced into a long spine, 

 as long as the club-joints. The tibiae without lateral teeth or 

 spines and the tarsi long. 



Variation of the male. In small specimens the head is quite 

 smooth, the mandibles flat, with their inner edges straight, 

 close together and entirely serrate. In larger specimens 

 only the basal part is serrate, the rest slender, with a tooth 

 near the middle and another near the tip. Two or three 

 longitudinal folds are visible on each side of the head. In 

 full-sized males about six such folds can be counted on eacli 

 side and the mandibles are long, curve gently downwards and 

 have the lower edge armed with a strong tooth a little beyond 

 the base, a smaller one past the middle and another before the 

 apex. The hollowed anterior part of the head is limited 

 behind by a fairly sharp curved carina.
