TORTRICINA. 11 



e e. With the apical joint as long as the 



5. BRACHYTJENIA. 

 ccccccc. Palpi with the middle joint 



six times as long as the apical ... 7. PENTHINA. 



Genus I. SARROTHEIPA, GUENEE. 



Head tufted above and between the eyes. Antennae setaceous, 

 inserted on the crown towards the front. Eyes large, subglobose. 

 Palpi much longer than the head, appressed, porrected upwards ; 

 basal joint shortest and curved ; the middle twice the length of the 

 basal, curving upwards; apical joint horizontal, straight, cylin- 

 drical, as long as the middle. Maxillae thrice the length of the palpi. 

 Thorax ovate, with a simple tuft behind. Anterior wings elongate, 

 length equal to twice the breadth; costa abruptly arched and 

 ciliated at the shoulder and towards the apex ; apex obtuse ; apical 

 margin subtruncate, oblique, rounded ; dorsal margin slightly 

 rounded. The costal vein reaches the costa beyond the middle ; the 

 six apical nervures all simple; the submedian nervure inserted in 

 the middle of the median vein. Posterior wings ample, apex ob- 

 tuse, apical margin concave. Legs : middle pair longest ; first pair 

 with brushes of hairs situated on the inner portion of the femur and 

 tibia. Abdomen slender in the tf , moderate in the $ . 



This genus is placed at the head of the Tortricina in con- 

 sequence of its affinity to Hylophila and Earias, which are now 

 separated into a distinct family. It approaches those genera by 

 having the pupa unarmed with transverse rows of minute spines 

 in the dorsal region of the abdominal segments, and by being 

 enclosed in a tough, closely-spun silken cocoon, somewhat like 

 an inverted boat. The appearance of the perfect insect, how- 

 ever, offers no resemblance to them, but is of the true Tortrix 

 character, much resembling Peronea : from this latter genus it 

 differs in the absence of tufts of elevated scales; for, although 

 the small dark spots on the surface of the wings have the ap- 

 pearance of being raised, it proceeds from an optical illusion, 

 owing to the spots themselves being of a dull velvety character 

 upon a shining surface. 



The structure of the palpi is abnormal, the terminal joint 

 being as long as the middle one, and nearly as stout, in both 

 respects differing widely from what usually obtains in this family. 

 The great length of the maxillae, too, is very remarkable ; but in 

 the neuration of the wings there is no departure from the typical 

 form.
