 obsolete; sligma fuscous, elongate-lanceolate, its apical half lying within the 

 marginal cell. Legs dark hoaey-yellow, thinly clothed with j'ollowish hairs; 

 trochanters and coxse i)ale yellow. Abdomen elongate-ovate, shining, finely 

 and remotely punctured, basal segment campanulate, second segment some- 

 what darker about the base; the sutural carinre prominent; dark fuscous,

This species is closely allied to A. vnicolor, Cresson, but may be 

 distinguished by the absence of the thoracic lines, and the di.stinct fus- 

 cous lateral carinao of the second abdominal segment.

 coarsely reticulate. Tegulse small, pale yellow. Wings hyaline, faintly irides- 

 cent, marginal cell ovate, first sub-marginal small, narrow, second short, 

 obliquely subquadrate, receiving the recurrent nervure near the base, stigma 

 prominent. Legs pale honey-yellow. Abdomen ovate, narrowed to apex,
