 in^equaliter punctulato, clypeo antice emarginato : pro- 

 thorace quam longiori (et postice quam antice) vix duplo 

 latiori, longitudinaliter (fere ut S. gibhicollis, Saund.) con- 

 vex(j, fortiter (in medio minus, ad latera magis, crebre)

 majori pone medium posita ; elytris punctulato-striatis, basi 

 sat fortiter (fere ut ^S'. gibhicollis, Saund.) antrorsum j)ro- 

 ductis, apice singulatim oblique emarginatis 2-spinosisque, 

 lateribus postice sat fortiter denticulatis, interstitiis (apice 

 summo excepto) vix convexis crebre vix subtiliter (fere ut 

 S. flav(e, Saund., sed paulo minus subtiliter) punctulatis ; 

 corpore subtus subtilius minus crebre (prosterno medio 

 magis fortiter) punctulato. Long., 7 1.; lat., 3 1. 

 The prothorax resembles that of S. gibhicollis, Saund., in 

 build ; the elytra having the somewhat depressed form (incurved 

 behind the shoulders, and at their widest beliind the middle) of 

 S. undulata, Don. The close comparatively strong puncturation 

 of the elytral interstices is a conspicuous character. The mark- 

 ings are not much like those of any other described Sfigmodera : 

 regarding the red colour as the ground of the upper surface, the 

 bluish-black marks are a long oval discal patch commencing on 

 the front margin of the prothorax, and continued backward to 

 behind the middle of the elytra, a large roundish spot on each 

 elytron behind the middle (touching the lateral margin, but not 

 the suture), the apical one-fifth of the elytra and the suture 

 between the discal patch and the dark apex.
