This species belongs also to the section of Ae. capifatiis 

 Westw. The head and the prothorax are black, dull, diffusely 

 and at the sides coarsely punctated. The anterior angles of 

 the head are truncated, the posterior rounded ; front margin 

 deeply excavated, the excavation limited by an acute tip on 

 each side. The mandibles are slender, flattened, each-one 

 armed with two teeth ; the basal tooth long and directed back- 

 wards, the median triangular tooth arising on the upper margin 

 is short and not curved upw^ards and inwards, but directed 

 immediately inwards. Prothorax broader than the head, the 

 anterior and posterior angles truncated and the truncation 

 somewhat excavated ; the sides nearly parallel ; in the disc we 

 may observe a faint groove. The elytra are pitchy-black and 

 have 6 longitudinal deep stripes. The sutural interval is 

 punctured and finishes at the- tip of each elytron ; the second 

 is punctured only in its beginning and on the interior sides, 

 the other-ones are smooth ; the shoulders and the outer margin
