SARROTHRIPUS RAMOSANUS. 



Branched Brush-leg. 



Order Lepidoptera. Fam. Tortricidee. 



Ty]pe of the Genus, Tortrix degenerana Hub. 



Sarrothripus Curt., Goda. — Penthina Och. — Axia Hiib. — Pyralis Fab., 



Lat. — Tortrix Hub., Haw. 



Antennae moderate, slender, setaceous, inserted on the crown of the 



head close to the eyes, covered with fine scales outside, velvety inside ; 



basal joint rather stout, cylindric and curved, 2nd small, remainder 



oblong (1). 



Maxillce very long and spiral (3). 



Labial palpi porrected nearly horizontally and forming a compressed 



beak much longer than the head, densely clothed with hairy scales (4) ; 



slender and triarticulate, basal joint short, recurved, 2nd long, clavate, 



recurved at the base, 3rd joint as long or longer, nearly filiform (4 a). 

 Head with the scales on the crown projecting beyond the forehead {1) : eyes 

 prominent and globose. Thorax with a thick tuft behind. Abdomen longish, 

 linear and tufted in the male, the apex conical in the female. Wings slightly 

 deflexed in repose ; superior with the costa straight, the shoulders very much 

 rounded and hairy, posterior margin truncated and convex, disc ivith one or 

 more tufts of scales : inferior ample, emarginate near the apex : cilia mode- 

 rate. Legs rather short and stout, intermediate the longest: thighs, anterior 

 with a long brush of hairy scales on the inside : tibiae, anterior short, unth a 

 spine and a long brush of hairy scales on the inside (8), intermediate and 

 hinder spurred at the apex, the latter with a pair of spurs a little below the 

 middle : tarsi b -jointed, basal joint long : claws and pulvilli minute. 

 Larvae with numerous long hairs ; 6 pectoral, 8 abdominal and 2 anal feet. 

 Pupae (*) inclosed in a boat-shaped cocoon. 



Ramosanus Hub. — Curt. Guide, Gen. 968. 2. — ramulanus Step., Wood. 

 Fuscous : head, palpi, collar and a great portion of the superior wings 

 ferruginous-brown, the latter with a dark longitudinal line, rayed at the 

 base and branched on its inferior margin, above it is a black spot of 

 scales ; 3 fuscous ocellated spots, with others more obscure, form an 

 irregular transverse line near the posterior margin, on which is a 

 second regular row of smaller dots. 



In the Cabinets of Mr. Bentley and the Author. 



A SMALL but fine group of Tortricidse is here selected on account 

 of a variety of striking characters which are not common to any of 

 the neighbouring genera, and the brushes of hairs attached to the 

 fore legs have supplied the name Sarrothripus. There is an un- 

 doubted similarity between this genus and Halias, pi. 575, as far as 

 regards the coloured pupae and the form of the cocoon, but it is only 

 necessary to refer to the trophi and members to be satisfied that no 

 close affinity really exists. To Peronea, pi. 16, it is I think much 

 more nearly allied : and on a comparison of these two groups one is 

 struck with the little attention that has been paid to the structure of 

 the Lepidoptera, when we know that tliey have hitherto been in- 

 cluded by every one under the same generic appellation; for such 

 wide diffei'ences in most of the other Orders would have been lonij
