FAMILY IX. LOZOPERIDJE. 



Very many of the species, and sometimes whole genera in this 

 family (Lozopera, Xanthosetia, Dapsilid), have the ground-colour 

 of the anterior wings yellow ; but their chief characteristic is 

 that the principal fasciae or markings take their origin on the 

 dorsal margin, are very frequently abbreviated, and run in a 

 direction more or less parallel to the apical margin. So generally, 

 indeed, is this the case, at least in the known British examples 

 of this group, that any species so marked may, without hesita- 

 tion, be referred to it. In the previous families the reverse of 

 this obtains; the fascia start from the costa, and proceed in the 

 direction of the anal angle. Except in Calosetia, the ocelloid patch 

 is wholly wanting throughout the family. 



The length of the anterior wings is generally more than twice 

 their width, in some species of the genus Lozopera more than 

 three times ; and in repose are held in a very detiexed position, as 

 it were compressed from the sides, and the produced cilia at the 

 anal angle, as in Eupcecilia, Dipoltella, and some other genera, 

 give to those insects a peculiarly pinched-up appearance, pos- 

 teriorly. The posterior wings are mostly of the various shades 

 of grey, and not unfrequently very emarginate or incised below 

 the apex. 



The larvse, so far as known (except Dapsilia], are internal 

 feeders. The greater part, if not all, the larvae of the extensive 

 genus Eupcecilia, will probably turn out to derive their nourish- 

 ment from seeds. 



The following is the tabulation of the eleven genera con- 

 tained in this division : 



A. Posterior wings acutely produced in the <$ , 

 and with the apical margin concave in the $ 



a. Palpi with the middle joint three times as 



long as the apical 1. LOBESIA. 



B. Anterior wings with the costa nearly straight., 

 or only slightly arcuated. 



b. With the upper surfaceofilie anterior wings 

 ornamented with tufts of elevated scales. 



c. Palpi with the middle joint Jive times as 



long as the apical 2. PHTHEOCHROA. 



b b. With the upper surface of the anterior 

 wings not ornamented with tufts of elevated 

 scales, 

 c c. Palpi with the middle joint nearly three 



times as long as the apical . . . . 10. DATSILIA.
