 acutely sinuate before the posterior angles, which are lobately 

 produced; mesonotum considerably longer than pronotum, 

 the cruciform elevation broader than long ; abdomen broader

(J. Body virescent, abdomen greyishly pilose; head with 

 a large fuscous spot on each side of front and two linear spots 

 on each anterior lateral area of vertex, the latter with two 

 central longitudinal black fasciae and a spot of the same colour 

 near inner margin of each eye ; pronotum with two central 

 black fascite, which are inwardly sinuate beyond middle and 

 ampliated at posterior margin, the lateral margins and fissures 

 black ; mesonotum with two central anterior fuscous or testa- 

 ceous spots and macular indications of a continuous fascia on 

 each lateral area; anal segment with a broad black basal 

 margin; anterior and intermediate tibiiB biannulated with 

 fuscous; apex of rostrum piceous; tegmina and wings 

 hyaline, the veins defining the ulnar areas to tegmina in 

 places black, the transverse veins at base of first, second, and 

 third apical areas moderately infuscated. 



In a female specimen from Ecuador the colour of the body 

 is brownish ochraceous, the abdomen above with piceous 

 suffusions, and the dark markings to the tegminal venation 

 larger and more maculate.
