CLASSIFICATION OF THE ASCALAPIILDJE. 



261 



Antennae much shorter than the wings ; those the <J much 

 twisted in the apical half, and subserrate internally in that 

 portion ; those of the $ nearly straight, and not serrate : club 

 shortly capitate. 



Eyes with the lower division much smaller than the upper. 



Thorax scarcely villose. 



Abdomen moderate : in the with a pair of short, cylindrical, 

 forcipate appendices, which are strongly spiny within. 



Leys with the spurs of the posterior tibiae about equal to the 

 first two tarsal joints. 



Hob. North India. 



Allied to Bubo ; differing in the form of the o* antennas and 

 of the anal appendices. 



Species. 



1. S. nimius, Walker. (Ascal. nimius, Walk. Cat. Brit. Mus. Neurop. 

 p. 429, S —A. luctifer, Walk. op. ext. p. 432, £ . 



Genus Helicomittjs, n. g. 



Wings as in JBubo, but with the axillary angle of anterior pair 



scarcely evident. 

 Antennae shorter than the wings ; in the <$ irregularly sinuous 



in the basal half; small tufts of hairs on the outer side of the 



basal portion ; club shortly capitate. 

 Eyes with the lower division one-half smaller than the upper. 

 Thorax scarcely villose. 



Abdomen slender, rather long, and without appendices in the <$ ; 



somewhat short in the $ . 

 Leys with the spurs of the posterior tibiae as long as the first 



tarsal joint. 

 Hob. North India, China. 



Allied to Bubo and Siphlocerus ; differs from the latter in 

 having no abdominal appendices, and in the form of the d 

 antennae. 



Species. 



1. H. insimulans, Walker. (Ascal. insiraulans, Walk. Cat. Brit. 

 Mus. Neurop. p. 429, <$ .) 



Walker makes no mention of the singular conformation of the 

 antennae of his type : possibly he considered these organs unna- 

 turally deformed.
