194 THE entomologist's record. 



overlap a little further, and are not unfrequently a little less 

 regular in the orderly arrangement of the rows of overlapping 

 eggs. 



In venosa the silky lustre of the group of eggs is more 

 striking than in any other species, but is approached by 

 rumicis. When first laid, the eggs are of a sulphur yellow, but 

 soon become reddish brown, with paler markings, much in the 

 pattern of rumicis, as regards size and arrangement, but less 

 definite and distinct and without the dark apical mark. The 

 ribs are fewer than in rumicis, about 41 to 45, being thus a 

 little larger and bolder ; the crenulations or secondary ridges 

 are somewhat more evident, and terminate towards the 

 summit or micropyle in rather more decided mammellse. The 

 diameter is from 0*95 to i"i mm. ; the height must be about 

 •4 mm., but I got no satisfactory measurement, owing to the 

 attachment of the eggs to each other. 



The larva, when newly hatched, is whitish, but soon gets 

 darker, and much resembles the other species of Viminia. 

 3.4, 6.7, 10. 1 1, and 13 are pale segments, 2 is also rather pale, 

 head black (as in others). The tubercles are distinctly larger 

 and darker in the dark segments, paler and rather smaller in 

 10, and especially so in 11. The anterior trapezoidals stand 

 up prominently, so that, seen laterally, they form a serrated 

 dorsal ridge, especially marked in 3.4, 5.6, and 12, and notably 

 deficient in 11 ; each has 3 hairs, except 4 in 9th and 5 in 

 12th segments ; the other tubercles have each i hair. The 

 hairs are long, about i mm. (larva 2 mm.), and several, 

 especially in 13, longer. The larva is rather paler than the 

 other Viminia, the tubercles being deep brown rather than 

 black. In rumicis, which comes nearest to venosa, the tubercles 

 are also not quite black as in the others, but are even rather 

 paler than in venosa. As the larva grows, the distinction be- 

 tween the pale and dark segments becomes more marked than 

 at first. The scutellum of the 2nd segment has 4 hairs on 

 either lateral half; this is the same as in the other Viminia 

 of which I have a note. As compared with rumicis, the larva 

 is paler, tubercles smaller and blacker, but the form of the 

 tubercles, disposition of hairs, and relative size of the nth 

 segment seem identical. In the full-grown (in 6th skin) larva, 

 the alternation of pale and dark segments is perhaps more 

 marked than in the other species of Vimt7iia. 



The description of the several stages becomes rather 

 monotonous. It is noted, as in the other species, that in the
