elytris striis dorsalibus 1-4 integris, 5 nulla, humerali ex- 

 terna suturalique dimidiatis ; i)ropygidio pygidioque punctatis ; 

 prosterno bistriato, strias posticia parum abbreviatis ; meso-

 L. 7^-8i miU. 



Oblong, somewliat cjllndrical, greenish blue, shining ; the 

 head, surface rather closely and coarsely punctured, with a 

 few very fine points on the interstices, marginal stria well 

 marked over and in front of the eyes, but indistinctly con- 

 tinued across the epistoma, epistoma slightly excavated ; the 

 thorax, lateral border rather broadly punctate, punctures less 

 closely set than those on the head and become scattered on 

 ajjproaching the di.sk, on the disk the points are very minute, 

 marginal stria strong at the sides, especially at the anterior 

 angle, and clearly continued behind the neck, there is a finn 

 scutellar point at a little distance trom the margin ; the elytra, 

 striae 1-4 complete, 5 wanting, sutural well marked from the 

 apex to the middle of the dorsum, thence just traceable to 

 the base, humeral external dimidiate and apical, internal 

 basal and very faint; the propygidium and pygidium are 

 clearly and coarsely punctate and in density similar to those 

 of the thoracic border ; the prosternum, anterior lobe with a 

 few large punctures intermixed wi;h fine ones, keel bistriate, 

 striffi abbreviated at the base and anteriorly bending towards 

 each other, surface with fine scattered points ; the meso- 

 sternum is somewhat acute anteriorly and is without a mar- 

 ginal stria ; the legs are black, anterior tibiae 5-denfcate. 



This species is the largest known in the genus ; it is less 

 cylindrical than P. viridis, Mars., and P. Raffrayi^ Lew., 

 but more cylindrical than P. chalyheus, Fahr.

Pachycrcerus octostriatus, sp. n. 



Oblongo-ovatus, parum convexus, nigro-violaceus vel nigro-pur- 

 pureus, nitidus ; fronts baud excavata, stria late internipta ; 

 elytrorum striis omnibus integris ; prosterno bistriato, striis (basi 

 excepta) parallelis ; mesosterno stria antice Integra ; tibiis anticia

Oblong-oval, somewhat convex, colour above I'ich dark 

 violet, changing to purple in certain lights, beneath black,
