punctate ; the latter extending to the apex of the elytra in the 

 male. Fifth and sixth abdominal segments of the d 1 broadly 

 emarginate at the apex. Intereoxal process of prosternum less 

 strongly arched and not attaining to a level with the coxae. 



Length 19-26 ; breadth 5-71 mm.

Bitsema, while placing this species provisionally in Callichroma, 

 considered that it ought perhaps to be made the type of a new 

 genus. But I see no necessity for this, since the species, except 

 for its slightly shorter mandibles and less strongly arched 

 prosternum, possesses all the chief characters of Pachyteria.

Mange. Oriental Eegion, extending to N. China and Japan, and 

 through the Malay Archipelago to N. Australia. 



Head raised between the antennae so as to form an obtuse ridge, 

 which is concave from side to side and sharply pointed at each 

 end ; mandibles moderately long, abruptly turned in at the end, 

 furnished each with a tooth on the inner margin between the 

 middle and the apex. Antennae about twice as long as the body 

 in the J a, little longer than the body in the 5 '> fi rs t joint 

 dentate anteriorly at the apex; third very little or not at all 

 longer than the fourth, subequal to or slightly shorter than the 

 fifth ; eleventh in the c? much longer than the tenth, subequal to 

 it in the $ . Prothorax with an acute conical tubercle or spine 

 at the middle of each side. Elytra long, more or less tapering 

 posteriorly, narrowly rounded at the apex. Hind legs much 

 longer than the middle or front legs ; their femora more gradually 

 thickened, and extended some distance beyond the apex of the 

 elytra. First joint of the hind tarsus almost as long as the 

 remaining joints united. Intercoxal process of prosternum 

 strongly arched, reaching in the middle almost to a level with the 

 coxae ; dilated at the hind end, but without reaching to the 

 epimera.

Metallic green or blue ; the legs and antennae violaceous blue ; 

 prothorax with a densely and finely punctuiate area faintly covered 

 with black pubescence on each side of the middle of the disc ; 

 elytra each with a broad band along the middle of the disc densely 

 covered with short black tomentum ; the side densely punctuiate, 

 a little less finely in front and very finely posteriorly ; the narrow 

 band between the suture and the black medio-dorsal band rugulose,
