punctured ; the prosternura is bistriate before the coxae ; the 

 mesosternum (not quite so shortened as tliat of Marseuli) is 

 punctulate, with marginal stria complete. 



The description above is drawn from a specimen from the 

 Chevrolat collection which Marseul named ebeninus, Er., but 

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

 ebeninus in his monograph (pi. xv. fig. 22), showing the 

 dorsal strise and punctuation very clearly, and the sternal stria 

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

 Argentina.

Zahromorphus rugicoUis. 



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

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

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

 humerali 1-6 dorsalibus omnibus iutegris, 5" cum suturali con- 

 nexa ; propygidio pjgidioque dense et grosse punctatis ; tibiis 

 anticis 3-dentatis.

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

 and rugosely punctured, frontal stria carinate and straight 

 anteriorly, mandibles concave, also rugose ; the thorax, 

 marginal stria line and complete, inner and outer lateral stripe 

 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, striae deeply impressed, subhumeral and 

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

 the propygidium and pygidium are densely and coarsely punc- 

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

 mesosternum feebly and widely emarginate, stria complete ; 

 the anterior tibise are 3-dentate. 



This species difters from pacliysoma, Ancey, and longicoUis, 

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

 and from the first by having only two lateral thoracic stria?. 

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

 fifth are not joined, and I have an example o^ p achy soma in 

 which these striffi almost join. The dorsal stride resemble 

 those of apis, Mars., a species from the C^ape which I have 

 not seen.
