OBSERVATIONS. 



Distinguishable from the tricolor by the black 

 spot of the thorax, and by the proportion of 

 this part, which is comparatively longer than 

 in that insect. Its antennae present the remark- 

 able character of the dilatation and irregularity 

 of the second joint of the antennae.
