with a large black or pitchy spot beneath on the sternum ; abdomen and 

 legs rufous; the hinder femora black, and their tibias whitish, with the

 Also rather uncommon : taken in June, at Darenth wood, and in 

 Norfolk.

Genus XIX.—SCIAPTERYX* mihi. 



Antenna 9-jointed, irregular, rather short and stout, pilose, basal joint robust, 

 2nd smaller, subglobose, 3rd as long as the 4th and 5th united, the last 

 somewhat longer than the 6th, which with the remainder gradually diminish 

 in length and thickness, the apical one being smallest and rather obtuse : 

 clypeus and labrum emarginated : head broad, large, rough : eyes small : 

 ocelli 3 : wings short, broad, punctured ; anterior with 2 marginal areolets, 

 divided by a curved nervure, and with 6 submarginal ones, the basal one 

 small, rounded; 2nd narrow, receiving 1 recurrent nervure; 3rd somewhat 

 triangular, receiving 2 recurrent nervures; 4th not extending to the apex of 

 the wings: abdomen short, stout, depressed, broad, acute at the apex : legs 

 short, simple : tibioi furnished at the tip alone with 2 short obtuse spurs. 

 In this genus the antennae are short, stout, and, as it were, some- 

 what distorted, the articulations being irregular ; the body is broad, 

 depressed, and rugose; the wings short, broad, thick, the anterior 

 "with the marginal areolets divided by a curved nervure, as in 

 Allantus, by which characters combined it may be known from the 

 other genera of this section.
