and behind, the middle), its greatest width (which is at the 

 middle) scarcely exceeding the width of the head across the eyes, 

 its surface evenly, somewhat strongly, and rather closely punctu- 

 late, with obscure traces of the middle part of a longitudinal 

 dorsal furrow. The elytra on close examination are seen to be 

 finely punctulate, but their readily noticeable sculpture consists 

 of a confused system of wrinkling, making them appear finely 

 shagreened, or coarsely coriaceous. To specify the degree of this 

 sculpture by comparison with a familiar species, I may say that 

 the general effect of the sculpture is a little less rough and 

 strong than that on the elytra of Z. bicolor, Le G. The upper 

 surface is glabrous or nearly so, the underside and legs densely 

 clothed with short hairs. The claws are red, the ventral seg- 

 ments are coarsely, squamosely, and rather closely punctulate.

Z. Murrayi, sp. nov. S Rufo-testacea ; labro, palpis, antennis 

 (basi picescenti excepta), femorum apice, tibiis, tarsis, meta- 

 sterno (episternis exceptis), et abdominis segmentis basalibus 5 

 (5i apice rufo excepto), nigris ; elytris la?te ca?ruleis ; capite 

 nonnullis exemplis antice infuscato ; hoc fortiter minus 

 crebre punctulato antice minus producto minus angustato ; 

 prothorace canaliculato vix perspicue punctulato, antice sat 

 fortiter angustato ; elytris minus subtiliter vermiculato- 

 punctulatis. Long., 5 1. ; lat., 1|^ 1. 



The antennae are about three fifths of the length of the whole 

 body ; joint 1 is piriform and strongly curved, in some 

 examples testaceous, decidedly shorter than in Z. cyanijyennis, 

 scarcely longer than half the distance between the eyes, about as 

 long as in Z. ruMica, but much more strongly curved, joint 2 

 about one-third shorter, 3 equal to 1, 4 scarcely so long 

 as 3. The head from the front of the labrum to the base is 

 scarcely longer than its greatest width, the front part nearly 

 parallel-sided ; the middle of a line joining the front of the 

 labrum, and the base of the head would fall between the inser- 

 tions of the antennae ; the labrum is transverse and sulcate down 

 the middle ; the clypeal suture is quite undefined. The pro- 

 thorax scarcely differs from that of Z. cyanipennis. The sculp- 

 ture of the elytra is on the same plan as in Z. cyanipennis and 

 Z. rustica, but is stronger, coarser, and less close than in either 

 of them. The specimens before me appear to be all males, but 

 (as usual in this genus) the soft hind body has become so much 

 distorted in drying that its shape is not the same in any two. 

 The first four or five ventral segments are compressed into a keel, 

 which, however, does not ahvays run down the exact middle 

 line ; the fifth is very feebly concave all across at the apex. The
