244 MANY-DOTTED WORM DESCRIPTION OF ITS MOTH. 



which was formerly placed by Mr. Stephens in the genus Ditula, 

 but in his last work (Catalogue of British Micro-Lepidoptera, p. 

 25) he makes it the type of a new genus, named Brachytamia, a 

 name meaningshort marked or short barred, in allusion to the 

 stripes upon its fore wings. And I propose to designate our in- 

 sect Brachytamia Malana, or the short-barred apple Tortrix, 

 whilst its larva will be most readily distinguished as the Many- 

 dotted apple-tree worm. 



This moth (see plate 3, fig. 5) measures from 0.80 to 1.15 across its wings 

 when spread. Its fore wings are ash-gray of a rather dark shade, but towards 

 their outer margins ashy-white and sprinkled with a few black atoms. A ser- 

 pentine black line towards their base extends from their outer nearly or quite 

 to their inner edge, this line being broader and less flexuous near its outer end, 

 and from this end a black streak on the outer edge of the wing reaches to the 

 base, where it meets a black band which runs across the anterior part of the 

 thorax. Parallel with this streak is another interrupted one, placed upon the 

 base of the cubital vein. From the middle of the outer margin a straight black 

 stripe extends obliquely towards the inner angle and ends abruptly near the 

 middle of the wing. Slightly back of this a small triangular black spot is 

 placed on the outer margin; and nearly half way to the tip is a second oblique 

 black stripe, parallel with the first and nearly as long, and from its inner end 

 a very zigzag and serpentine black line runs across to the inner margin. On 

 the hind part of the wing the middle veins are black, commencing at their 

 forks, forming about four slender longitudinal lines. Near the centre of the 

 wing is often a round whitish spot having a black dot in its middle. The hind 

 wings are dull whitish, slightly dusky towards their tips. Both pairs beneath 

 are silvery whitish thickly sprinkled with blackish points towards their outer 

 sides, and on their hind edge is a black line which is slightly interrupted by 

 the tips of each of the veins. The head and thorax are of the same ashy-white 

 color as the outer part of the fore wings. The head has an elevated transverse 

 ridge or crest between the bases of the antennae and another below this upon 

 the middle of the face, the space between these crests being occupied by a black 

 band. On the hind part of the thorax the scales are also elevated, forming a 

 semicircular crest. The antennas in the males are pectinated with two rows 

 of short robust branches. Those of the female (fig. 5 a) have rows of ex- 

 ceedingly fine short hairs along their insides. 



A species which is closely related to the one now described 

 may be found in the forests early in the spring, before the leaves 

 have put forth. It is of an ashy white color with a large three- 

 sided black spot on the middle of the outer margin of the fore 

 wings, from which it may be named 



f The triangular-spotted tortrix, Brachytania triquetrana. Its ex- 

 panded wings measure 0.80. The shoulders or outer bases of the fore wings 

 are occupied by a short broad black stripe, and immediately back of this is a 

 black transverse angular mark, shaped like the letter V, with its inner part 

 more or less interrupted into two or three small spots. The triangular black
