 four lateral spots at the corners of the mesonotum ; abdominal

 type specimen of this very distinct species was unfortunately damaged 

 after description. It is probably not uncommon, but the collection of 

 further specimens and of its larvae is a desideratum.

Plate xiv, fig. 24, Venation of ? wing ; fig. 25, Head and thorax ;
