Leoviti'us is allied, and tVoni which it may be separated by 

 the lateral lobes of the head not meeting- in front, the relative 

 lengths of joints both to the antennai and rostrum, the length 

 of the abdominal spine, tSic.

Walker writes concerning the last: — "The spines of the 

 thorax are longer than those of the preceding species." I 

 cannot, however, appreciate any essential difference in this 

 respect. 



Genus AllADUCTA. 

 [Walker, Cat. Ilet. ii. p. 408 (18G7).] 



Subelongate, head and pronotum anteriorly deflected. 

 Head broad, lobes of equal length, convexly rounded. An- 

 tennai with the basal joint thickened and not. reaching apex 

 of head, second and third joints subequal in length. Pro- 

 notum moderately gibbous at base, deflected towards head, 

 lateral margins obliquely straight, posterior angles either 

 rounded or angularly prominent. Scutellum broad at base, 

 apical half narrowed, apex rounded. Abdomen narrowed 

 towards apex, widest at about centre. Rostrum reaching the 

 intermediate coxie, second joint a little longest. Mesosternum 

 ■with a distinct keel, narrowed in front, not extending beyond 

 anterior cox£e. Metasternum with a central cruciform process 

 not notched posteriorly. Second abdominal segment with a 

 central short, broad, obtuse, spinous tubercle. 



Walker erroneously describes a " ventral spine extending 

 to the middle coxa?.'" He has not distinguished between the 

 metasternal process and the small tuberculous ventral spine. 



I have placed this genus in the group represented by 

 Brachystethus. It here comprises some diverse forms, but I 

 have relied on the character of the sternal processes, and have 

 thus regarded Araducla with the same latitude as is applied 

 to the genus Edessa.
