GEOMETRID/E. SPERANZA. 145 



Genus CLXIII. — Speranza, Curtis. 



Palpi somewhat horizontal, thickly squamous, the terminal joint distinct, tri- 

 articulate, the basal joint slightly curved, and of equal length with the second 

 the apical one minute. Antennce slightly pectinated in the males, each joint, 

 excepting the three or four terminal ones, producing a subclavate ciliated 

 branch on each side, shortest towards the base: /jeac? small: thorax rounded: 

 ivings flavescent or luteous, with their hinder margins entire ; anterio?; in 

 the male, with a tubercular elevation on the upper surface near the base 

 which is hollow and denuded beneath : femora elongate; tibia; short, anterior 

 with a spine on the inner side ; posterior with two pair of spurs. 



The absence of pectinations towards the apex of the male an- 

 tennae disting-uishes that sex from the following genus; and the 

 females may be known by their flavescent or luteous hues, more or 

 less bordered or irrorated with black or dusky. S. limbaria is double- 

 brooded, being found in June, and again in September ; but whether 

 that is the case with the other species I am not aware.

 tibus. (Exp. alar. 10— 11 lin.)

Steph. Catal. part ii. p. 114. No. 6439. 



Rusty-ochraceous, with obscure dark speckles, with four very indistinct dark 

 sinuated transverse striga;, and a minute spot of similar hue in the centre ; 

 posterior Avith two bent strigje and a dusky central spot : ciha of all pale 

 fuscous : beneath orange, with deeper irrorations, and two or three darker 

 strigae. Female darker, with the strigse broader and more distinct. 



I have no doubt that this species is synonymous with the Geo. bruneata of 

 Thunherg, consequently I have adopted his name as being first published : 

 the Ge. quinquaria of Hiibner, and his Ge. Pinetani, which is the female of 

 the last, are closely allied, if they "be not intended for the same. 



All the examples that I have hitherto seen of this interesting 

 species were captured in Scotland " on the 24-th July, 1827, on 

 heath amongst the pine-trees in Black-wood, near the shores of 

 Loch Rannoch." — Curtis., I. c.
