on the costa, terminating in a similar one on the inner margin. The central line is 

 less distinct, but is more defined than in virgularia, the sub-terminal line is not 

 dotted, as in that species, but is a frequently-toothed, well-defined, dark grey stripe, 

 and is followed by a darker shading, which is edged on the outside by a light curved 

 band. Hind-margin dotted with black. Fringes grey. 



With the exception of the first line, the markings are all continued through the 

 posterior- wings, but the sub-terminal line is very dark and broad. In the ^ the 

 colour is paler, and all the markings less distinct, except the central spots, which 

 are more sharply defined, and the sub-terminal line, which is dotted somewhat as in 

 virgularia. In this sex, the shape of the posterior-wings differs from that insect, 

 the hird-margin having semicircular dentations, making their outline almost angular, 

 and the marginal black dots form an almost continual line. 



The J measures 20 mm., the ? 22 mm. 



Only two specimens of this insect were taken at Guelmain June, 

 both of which are in my collection. 



ACIDALIA TEREJfTIUS, 01. Sp. 



Alee onines, ocTiraceo-hrimnecB , lineis mediants et suh-terminalihiis parallelis, 

 hrunneis. Alee anticce apice sinuato. 



This species is of an ochre-brown colour, the basal space being darker brown. 

 The median brown line is parallel with the broad sub-terminal line of the same 

 colour, both being almost parallel with the hind-margin, and extending from the 

 costa up to the inner margin ; these two lines are also continued through the pos- 

 terior-wings, but are less distinct. The hind-margins of the anterior and posterior- 

 wings are bordered by a distinct dark line. The fringes, which are exceptionally 

 long, have the basal half darker brown, with paler extremities. There is a slight 

 gloss over all the wings. The thorax and abdomen are brown ; antennae paler brown. 

 The apex of the anterior-wings is rather sinuate. 



Only two specimens were taken at Lambessa in April, one is in 

 my collection ; it measures about 13 mm. 



Ltgta Jouedanaria, var. obscuea. 



Anterior- wings umber-brown, with all the white markings of Jourdanaria re- 

 placed by a paler brown colour. The hind-wings are also of a browner hue. 



In the ? the ground-colour is paler than in Jourdanaria, with the white mark- 

 ings also replaced by paler brown ones. 



Jourdanaria was common at Lambessa in April, and existing with 

 it was this almost unicolorous variety which, being constant and not 

 uncommon, is well worthy of a distinctive name. I possess a cJ and ? . 



EUPITHECIA AETEMISIATA, Coust., Var. CONSTANTIKA. 



Anterior-wings brownish-grey, the first darker band, edged on the outside with 



white, is sharply angulated near the costa, and is very distinct, in front of this {i. e., 



near the base) are one or two more or less distinct paler lines. Before the median 



stripe, which is narrower and edged on the outside by a double white line, is a
