irregular punctures; the meso- and metasterna are somewhat 

 opaque, but are impunctate, with a microscopic strigosity. 



Sajyrinus felipce, sp. n. 



Ovatus, niger, nitidus ; fronte grosse punctata, stria antice tenuiter 



impressa ; pronoto lateribus punctato, stria marginali integra ; 



elytris striis 1-4 dimidiatis, iuterstitiis la3vibus, postice punctatis ; 



propygidio pygidioque dense punctatis, hoc in medio anguste 



lsevi. 

 L. 9 mill. 



Oval, convex, black, and shining ; the head and epistoma 

 markedly and densely punctate, stria rather obscurely marked 

 anteriorly ; the thorax, marginal stria complete, and along 

 the sides is a band of coarse punctures, points largest and 

 most dense behind the anterior angle, along the 'base there is 

 a narrow border of points which do not quite reach the 

 scutellar region ; the elytra are striate and similar to those 

 of lugens, Er. (Mars. Mon. fig. 34), but their interstices are 

 smooth, the dorsal punctuation is limited to about half the 

 area between the sutural stria (which is shortened anteriorly) 

 and the fourth stria, and outwardly the punctures occupy less 

 space, not encroaching on the striae; the pygidia are closely 

 punctured, the pygidium has a medium smooth line and at 

 the sides a carinate margin ; the prosternum, the striae are 

 complete, joining at both ends, and widen out before the 

 middle, and are angulate at the widening ; the mesosternura, 

 marginal stria lightly impressed but complete, and the suture 

 indicated by punctures. 



This species is larger than S. lugens, Er., and it is easily 

 distinguished from it by three characters, viz. the interstices 

 of the dorsal striae are smooth, the pygidium has a smooth 

 median line, and the prosternal striae are angulate near the 

 middle.
