Observations on the Species and Varieties of Lozotmnia. 

 By William Bentley, Esq. 



Genus Lozo taenia, Stephens. 

 Tortrix, Hubner, Haworth, Fischer. 



In offering a few remarks on the species and varieties of this diffi- 

 cult group of insects, it is essential to state that some of the species 

 take a wide range of variation in size, colour, and in markings. 

 I attribute much of this to the well known fact, that many of the 

 species are general feeders, the larvae feeding indiscriminately upon 

 most of our trees and shrubs : the species, too, are generally widely 

 dispersed. Locality, also, may have some influence in causing such 

 diversity in size, colours and markings. Some of the varieties, and 

 even the sexes, were formerly considered distinct species by foreign 

 authors, and figured as such by Hubner ; but time and subsequent 

 observations enable us, in some degree, to correct such errors. 



Sp. 1. Lozotjenia Forsterana, Stephens, II. Brit. Ent.Haust. iv. 70. 



Tortrix Forsterana, Haworth, 421. T. adjunctana, Fischer, PI. ix. 



fig.l. 

 Measures 9 lines to 1 inch 2 lines. Anterior wings broad, of a 

 cinereous tinge, slightly reticulated, with three dark brown spots, two 

 upon the costa, the other on the inner margin, forming a triangle : this 

 species varies but little, except in size ; common about gardens and 

 hedges in June. It is known on the continent by the name of 

 adj unctana. 



Sp. 2. LOZOT.ENIA SORBIANA. 



Tortrix Sorbiana, Hubner, PI. xviii. fig. 113. T. Avellana, 



Haworth, 421. 

 Measures 10 lines to 1 inch 3 lines. Anterior wings grey, with a 

 yellowish tinge, with an oblique dusky baud at the base, and a second 

 a little behind the middle, which is often interrupted ; between this 

 second band and the tip is a dark patch on the costa : posterior 

 wings dusky, with yellowish cilia. A variable insect ; but all the va- 

 rieties may be known by the shortness of their palpi. 



Sp. 3. L0Z0T,ENIA HEPARANA, Steph. 1. C. 71. 



Tortrix Carpiniana, Hubner, PL xviii. fig. 116. T. Carpiniana, 



Haworth, 422. 

 Measures 7 to 11 lines. Variable; in some examples the wings 

 are testaceous brown, reticulated with darker brown ; in others they
