punctured ; the prosternum is bistriate before tlie coxae ; the 

 inesostenium (not quite so shortened as that of MarseuU) is 

 punctulate, with marginal stria complete. 



The description above is drawn from a specimen from the 

 Chevrolat collection which Marseul named ebenimis, Er., but 

 it is clearly not so. Marseul gives an excellent figure of 

 eheninus in his monograph (pi. xv. fig. 22), showing tlie 

 dorsal strise and punctuation very clearly, and the sternal stria 

 also are separately shown. Erichson's species is a native of 

 Argentina.

Zahroinorphus rugicoUis. 



Oblougo-ovalis, convexus, niger, nitidus ; fronte rugoso-puuctata, 

 stria carinata, antice recta ; pronoto striis 2 lateralibus integris, 

 utrinque grosse et dense strigoso-punctato ; elytris striis sub- 

 humerali 1-6 dorsalibus omnibus integris, 5* cum suturali con- 

 nexa ; propygidio pjgidioque dense et grosse punctatis ; tibiis 

 anticis S-dentatis.

Oblong-ovalj convex, black and shining ; the head coarsely 

 and rugosely punctured, frontal stria carinate and straight 

 anteriorly, mandibles concave, also rugose ; the thorax, 

 marginal stria fine and complete, inner and outer lateral strise 

 also complete, the former continuing behind the head, surface 

 behind the middle of the neck punctured not very closely but 

 laterally and broadly behind the angles, the surface is strongly 

 and longitudinally strigose, the strigosities continuing but 

 gradually narrowing to the base, behind the middle of the 

 disk and along the base there is an irregular space almost 

 smooth ; the elytra, strife deeply impressed, subhumeral and 

 dorsal all complete, the fifth and sutural joining at the base ; 

 the propygidium andpygidium are densely and coarsely punc- 

 tate ; the prosternum, keel narrow, anterior lobe bistriate; 

 mesosternura feebly and widely emarginate, stria complete ; 

 the anterior tibiae are 3-dentate. 



This species differs from jxichysoma, Ancey, and longicollis, 

 Mars., by the conspicuous strigose sculpture of the thorax, 

 and from the first by having only two lateral thoracic stride. 

 I have seen an example of rugicoUis in which the sutural and 

 fifth are not joined, and I have an example of pachysoma in 

 which these strife almost join. The dorsal strise resemble 

 those oi ajns, Mars., a species from the Cape which I have 

 not seen.
