428 CATALOGUE OF 



Fore wings broad ; costa slightly rounded along the basal half; space 

 between the scapular vein and the costa with large areolets (which form two 

 rows towards the base) and with numerous small irregular areolets ; scapular 

 and externo-medial vein approximate and nearly parallel to each other; 

 hinder part with numerous irregular areolets, each of which incluiles some 

 small irregular areolets. Hind wings pellucid ; veins pale. Length of the 

 body 15 — 17 lines; expansion of the fore wings 46 — 50 lines. 



The head is more elongated than that of A. carinatum, and it differs 

 much from that species in the structure of the legs.

 longius, carina lanceolata antennarum articulo lo ccguilata, fronte 

 subexcavata; antennte sat valid ce ; pruthorax marginibus antico et

Female. Green or testaceous, slender. Head and prothorax tubercu- 

 late. Head elongate, narrower in front, longer than the prothorax; keel 

 of the vertex lanceolate, as broad at ihe base and nearly as long as the first 

 joint of the antennae; front slightly concave in the disk, conical between 

 the sockets of the antenna). Eves tawny, short-elliptical, prominent. 

 Antennae long, rather stout. Prothorax with a smooth longitudinal stripe 

 which interrupts the two strongly marked abbreviated transverse impressed 

 lines ; fore border and hind border much rounded ; sides tuberculate, 

 slightly rounded. Oviduct less than half the length of the abdomen; 

 apical half black. Legs stout; four anterior femora with a few extremely 

 minute spines ; hind femora about one-third of the length of the fore 

 wiugs, with six rather large spines on the outer side and with a few minute 

 spines on the inner side; tibia; with a few minute rudiments of spines. 

 Fore wings narrow, lanceolate, minutely reticulated ; space between the 

 mediastinal vein and the costa with many irregular rather small areolets; 

 one row of larger and more regular areolets between the mediastinal and 

 the scapular ; a few areolets between the scapular and the externo-medial, 

 where they diverge from each other; two and exteriorly three posterior rows 

 of large regular areolets ; a row of small quadrate areolets along the 

 interior border. Length of the body 20 lines; expansion of the fore wings 

 44 lines. 



The hind wings are but slightly developed in the two specimens 

 described. The much longer head distinguishes it from A. porrectutn, to 

 which it has most affinity.
