base, tlie fifth ?tiia turns outwards at the apical eflj^p, tlie 

 iniK-r subhunieral is conij:)lete, outer humeral short and basal 

 (these two strige are similar in all the known species) ; the 

 propygidium is very finely punctnlate over the whole surface, 

 and there is a basal lateral stria (common also to the other 

 known species) ; the pygidiura is much less distinctly punc- 

 tnlate and is obcurely reddish brown, not apparently owing 

 to immaturity ; the prosternal keel is margined along its 

 base like that of Psiloscelis harrisi, Lee. (a character also seen 

 in the other s])ecies) ; the mesosternum is narrowly sinuous 

 and marginate ; the anterior tibite are 3-dentate. 



There are now five species of this genus known, and with 

 the additional species it is easy to see that the characters 

 referred to in parentheses should be considered generic. In 

 Confipus the pygidia are simply convex.

Zahromorphus pingxds, sp. n. 



Oblongo-ovatus, convexus, niger, nitidus ; fronte impnnctata, stria 

 Integra antioe recta ; pronoto ciliato, striis integris, parallelis, 

 interstitiis latis ; elytris striis latis, crenulatis, 1-4 integris, 5 et 

 Buturali vix abbreviatis ; propygidio pygidioque grosse punctatis ; 

 prosterno basi marginato ; mesosterno antice emarginato, stria 

 Integra recta. 



L. 9^ mill. 



Oblong-oval, convex, black and shining ; the forehead 

 smooth, stria very strong and straight anteriorly ; the thorax, 

 lateral strige deep, outer stria ceasing behind the eye, inner 

 continued behind the head, lateral interstice wide, with a 

 few marks and punctures at the angle; the elytra, striaa 

 deeply impressed with creimlate edges,- inner humeral apical 

 and just passes the middle at the point where the outer 

 humeral ends, the dorsal strige 1-4 complete, 5 a little 

 shortened at the base but not at the apex, sutural less 

 shortened in front but similarly shortened behind ; the pygidia 

 are coarsely punctate ; the prosternum is marginate along the 

 base of the keel ; the mesosternum emarginate, stria well- 

 marked and straight anteriorly; the anterior tibiae 3-dentate. 



This species differs from Z. hngicollis. Mars., by the head 

 being without fovea and the greater depth and completeness 

 of the elytral striaj; in outline it is very similar. The form 

 of the inner humeral stria may be considered a generic 

 character of Zahromorphus.
