of long slender spines, those upon the posteriors very short, tibiae densely 

 spinous. 



Length 9 lines. Abdominal breadth 5. Hong Kong. 



This species must be closely allied to A. rugosus, Dallas ; but in that spe- 

 cies the middle lobe is represented to form the anterior margin of the head, and 

 nothing is said of spots upon the membrane.

 to each end, eyes brownish-glaucous, with a posterior, narrow yellow lobe, promi-

 with reddish upon the apex of the corium, membrane yellowish-hyaline, the 

 nervures having interrupted brown lines upon them ; beneath less closely punc. 

 tured, upon the pectus several spots of dense green punctures, under surface 

 of the head also punctured in green spots; disk of the venter, with a broad, 

 smooth, impunctured line, surface tinged with reddish, stigmata, and obsolete-
