stigmate nervis fuseis. Corpus totum loeve, nitidiusculmn ; 

 segmentum Imum latitudine sesquilougius, marginatum, lateribus 

 parallelis, apice truncatum, angulis- rotunclatis ; 2clum longius 

 quam A. abjecto, 3tio tiequale, transversum, lineis 2 obliquis 

 antrorsum convergentibus aream triangulareni lievem includentibus 

 impressum. Terebra brevissima. Valvula ventralis anum non 

 superans. Coxae posticiie lieves. Calcaria postica metatarsi dimidio 

 paulo longiora. 



Black ; palpi pale ; belly at the base rufescent ; legs testaceous, 

 with black coxte ; posterior femora more or less edged with black 

 above and beneath, or wholly pale ; apical half of hind tibiae, with 

 their tarsi, fuscous, the latter testaceous at the base. Wings 

 hyaline, squamulae, stigma, and nervures fuscous. Body smooth, 

 slightly shining ; segment 1 half as long as its breadth, margined, 

 with parallel sides, truncate at the apex, the angles rounded ; 

 2 longer than in A. abjectus, as long as 3, transverse, impressed 

 with two oblique lines converging forwards and enclosing a smooth 

 triangular space. Terebra very short. Valvula ventralis not 

 surpassing the anus. Hind coxae smooth. Si)urs of hind tibiae a 

 little longer than ^ the metatarsus. ^ 5 . Length, 1^ ; wings, 3i lin. 



This species is very near immunis, Hal., but certainly 

 distinct ; the triangular space on the 2cl segment is 

 smooth, and the cocoons different. 



A solitary parasite of Geometrae. Bred by Bignell, 

 S" ? , from Cahera pusaria, L. ; ? , from lodis lactearia, 

 L. ; 3" , from Selenia hilmiaria, Esp., and Lomaspilis 

 marginata, L. The cocoons, in which they remained, in 

 one case, from September to April, are brownish white, 

 like those of abjectus.
