Palpi pitchy, mandibles black, clypeus bearded with pale pube- 

 scence, which is also thinly scattered over the whole body. Meta- 

 thorax acutely bidenticulate, and with several longitudinal carinse, 

 two of which are elevated at the apex ; hence subquadrideutate. 

 Abdomen bicarinated and reticulato-rugose at the base, ruguso- 

 punctate towards the apex, and glistening with hoary pubescence. 

 The yellowish abdominal spots are triangular, and smaller than in 

 the similar I'juropean species ; in one female, obsolete. Wings 

 hyaline towards the base, with decolorous nervures; dusky towards 

 the apex, with fuscous stigma and neuration ; cubitus and anal 

 nervure attenuated outwardly and subobsolete ; 3d abscissa of the 

 radius not sinuated ; radial arcolet shorter and more obtuse than 

 in C. inanitus. 



Common in the West Indies ; I found several of both sexes in 

 Barbados, Martinique, and Antigua.
