half of the mandibles, palpi, the upper edge of the propleura, 

 the lower more narrowly at the base aud apex, 2 Unes ou 

 the mesouotum, the sides of the scutellum — the mark broad 

 at the base, becoming gradually uarrowed towards the apex — , 

 post-scutellum, a mark ou the apex of the median segmeut, 

 half ou the spiracular, half ou the posterior lateral area, 

 the lower half of the mesopleurae, the mark rouudly iucised 

 ou the top at the base aud exteudiug ou to the mesosternum, 

 a mark ou the ceutre of the latter, becoming gradually 

 uarrowed towards the base, 2 marks on the first abdominal 

 segment, dilated inwardly at the apex aud 2 marks ou the 

 apices of the 2nd to 5th segments, the marks becoming gra- 

 dually smaller, pale yellow. Legs pale yellow, the 4 front 

 femora broadly above, the hinder all round, except at the 

 apex, the hinder coxae, except at the base above aud at the 

 apex below, the apical joint of the hinder trochanters, the 

 tibiae and nietatarsus, to shortly beyond the middle, black. 

 Wings hyaline, with a distinct fuscous-violaceous tint; the 

 nervures and stigma black. cf. — Leugth 15 mm. 



Antennae black, the scape and pedicle pale yellow beneath. 

 Face closely puuctured, the clypeus sparsely punctured above. 

 Mesonotnm distiuctly, but not very closely, puuctured. The 

 base of the metauotum with a few distiuct punctures on the 

 outerside ; the areola is uot clearly defined, especially behiud ; 

 it is obscurely puuctured and is separated from the base of 

 the segment by double its own leugth ; the upper half of 

 the posterior median area distiuctly aud closely puuctured, 

 the lower aciculated. Propleurae puuctured at the apex, the 

 middle with some curved keels aud furrows ; the uieso- more 

 closely aud regularly and the "meta- still more closely and 

 strongly punctured. The raised central part of the post- 

 petiole is strongly aud closely longitudiually striated ; the 

 other segments are closely punctured ; the 2ud and 3 r( i lougi- 

 tudinally striated in the centre to uear the apex ; the 4th 

 at the base only ; the segments are tinted with violet at the 

 bases. Gastrocoeli large, deep smooth. Areolet narrowed at 

 the top, the nervures almost uuiting there. The upper keel 

 on the metasteruum becomes weaker towards the apex ; the 

 lower is strouger and complète. 



Cornes close to A. coeruleodomali Cam. with which it 

 agrées in having the markings pale, uot yellow, in the 

 abdomen being blue and in the areolet being uarrowed in 

 front ; but that species may be kuown by the areola being 

 separated only by its owu leugth from the base of the 

 segment and by the posterior median area being closely 

 transversely striated.
