Pachycrccrus cavtfronsy sp. n. 



Cylindricus, brovis, viridi-a;iieus, nitidus ; capite anticc tlypcoque 

 profunde oxcavatis ; pronoto stria raarginali anticc intcrrupta ; 

 elytris, striis 1 basali dimidiata, 2-3 brcvibus, sutiirali apice 

 abbrcviata ; prostcrno angustato, bicarinato ; mesosteruo utrinque 

 striato ; tibiis anticis 9-dentatis. 



L. 2| mill. 



Cylindrical, short, truncate anteriorly, brassy green, shining; 

 the head in front of the eyes and epistoma widely and deeply 

 excavated, base of the excavation vertical ; the epistoma is 

 wide and transverse, with anterior edg-e sinuous, mandibles 

 large, with outer edges raised, frontal stria obsolete, surface 

 microscopically strigose, with small and larger punctures 

 interspersed ; eyes large and transverse ; the thorax sculp- 

 tured like the head, wider than long, lateral stria ceases at 

 the anterior angle, which is somewhat im))rcs3cd and angular ; 

 the elytra — strias, external subhumeral complete, internal 

 dimidiate, 1 dorsal, basal, and dimidiate, 2 basal, half length of 

 first, 3 basal and very short, sutural commences near the 

 middle of the dorsum and nearly touches the base, and for 

 half its length turns a little away from the suture ; the pro- 

 pygidium and pygidium are sculptured like the head; the 

 prosternum, anterior lobe is large and transverse, the keel 

 short, narrow, and straight, and built up from its base, its 

 narrowness brings the anterior coxre into proximity ; the edges 

 of the keel are carinate, the carinas exactly parallel to one 

 another; the mesosternum is rather wide and the acumina- 

 tion robust, striate at the sides only ; all the sternal plates 

 are sculj)turod like the head; the anterior tibite have nine 

 coequal and equidistant teeth, the thighs are reddish, tibiae 

 obscurely reddish brown. 



This remarkable species has the superficies of a species of 

 Teretri'osoma, but I see no reason for not assigning it to the 

 genus Pachycrrp.rus.

 elytris striis basalibus 1-3 abbreviatis, 4 brevissiraa, suturali 

 pone medium abbrcviata ; prosterno antice arcuato, margine 

 lateral! carinato ; tibiis anticis G-7-dcutatis.
