of tlie Species of the Genus Pachyrhynchus. 313 



rostrum is proportionately broader and rather shorter, the thorax 

 is also broader and rather less constricted before and behind, and 

 the elytra are proportionately narrower and more elongated : it is 

 of a rich copper-red colour, but presents a slight a?neous tint in 

 parts and in certain lights. The rostrum is very delicately punc- 

 tured and has a shallowish transverse impression in a line with 

 the base of the antennae, there is also a broad and very shallow 

 oblong depression on the head — both these depressions are filled 

 with pale blue-green scales, and there is a patch of similar 

 scales on each side beneath the eye and another on the side of the 

 rostrum. The thorax is smooth, has a transverse blue-green line 

 in front and another behind, and these lines are joined by a broader 

 mark on the sides, which passes close to the femora ; on the upper 

 surface are three longitudinal marks, and one central transverse 

 mark ; this latter is slightly interrupted, otherwise the disc of the 

 thorax would be divided into four areas. The elytra are faintly 

 punctured, and the punctures form striae ; on the apical portion 

 of the elytra the punctures are more distinct : a line of scales 

 borders the outer margin of each elytron, extending from the base 

 almost to the apex ; at the base it is recurved and runs up towards 

 the suture, but stopping at a short distance from the suture it 

 sends off a longitudinal line which extends very nearly to the 

 apex of the elytra and there joins the marginal line ; this longi- 

 tudinal line is slightly interrupted in the middle of the elytra, 

 where there is a transverse band. Besides these lines, all of 

 which are formed of pale blue-green scales, there are two abbre- 

 viated longitudinal marks running from the base of the elytra on 

 each side, and two small spots situated on the apical half of each 

 elytron.

This species is considerably larger and more elongated in form 

 than P. moniliforus. It is of a brilliant copper colour, and 

 smooth : the forehead and base of the rostrum are concave, and 

 the latter has a deep transverse impression ; on the head above is a 

 round spot, and under each eye is an oblong spot. The thorax 

 has two oblique patches above, and a broadish mark on each
