space on the elytra reaching from scutellnm to near middle, widened behind to 

 lateral margin and here extending forward and backward, and a transverse, slightly 

 carved, band of even width at apical fourth, black ; within the black proximal area 

 of the elytra there is on each a yellowish white angle-shaped mark, beginning at 

 sntnre at basal fourth or fifth, slightly and gradually widening behind, and turning at 

 an obtuse angle towards the side before reaching the hinder edge of the black area, 

 the transverse branch stopping in middle of disc; before and laterally of the tip of 

 the transverse branch there is a linear oblique spot ; the black area itself posteriorly 

 edged with yellowish white ; a spot on coxae, a spot above anterior coxa, meso- aud 

 metasternal episterna, aud a transverse, ajneal, lateral spot on first and second 

 abdominal segments, creamy white. Prothorax longer than mesially broad, 

 reticulate as in Phyionotidus, elytra elongate : hindfemnr nearly reaching apex of 

 elytra ; legs coarsely rngate ; no carinae on femora. 



Length, 16—18 mm. ; elytra, 11—12 mm. ; breadth, 3A — 4 mm.

E. Plagionotulus (ld04J Jord. (type : lijvicen). 



Antennal groove large, open ; frons separated from occiput. Prothorax 

 globular. Femora carinate. 



Plagionotulus lyricen (1804) Jord. 



I am not certain that lyricen is distinct from Chjtanthus climidiatas (1882) 

 Qned., and from Clytus contractifrons (1890) Bates, the descriptions of which fit very 

 well the present species. 



Plagionotulus senegalensis (1841) Lap. & Gory. 

 In the British Mnseum from Senegambia. Closely resembling the preceding. 



Plagionotulus westringi (1872) Fahrs. 



Syn. : PL cinercm (1894) Jord. 



I have no longer any doubt that the two names apply to the same insect. 



F. Denticerus (1894) Jord. (type : reticulatus). 



Like I'layionotidiis, but antennal segment 3 and following produced into an 

 acute tooth at apex on innerside. ' 



It is [lossible judging from the description, that Clostrocera (1834) Serv. is the 

 same as Denticei-us. 



The second species described as Clostrocera, namely tricolor (1840) Gut$rin, is 

 doubtless an Apioyaster (see above, sub No. 23).
