150 THE entomologist's record. 



is more brilliant and striking, but has not quite the richness 

 and velvety smoothness of alni or anricoma ; very few indeed 

 even of this variety have all the hairs quite black. The blackest 

 have the red lateral spots occasionally rather smaller, divided 

 into three, that behind the tubercle being divided into two, and 

 not extending forward beyond the 6th segment. As other black 

 ones have the lateral marks in the ordinary form, it may be an 

 accident that this variation in the lateral line occurred in the 

 blackest specimens. 



The pupa (Plate II., fig. 2) is the largest and stoutest of this 

 group, igmm. long by 6 mm. in width, its outline is nearer to 

 myriccB than to riimicis. The frontal knobs are lower, rounder 

 and closer together than in the other species. The hoops of the 

 hooped segments form a distinctly raised band, less pronounced 

 than in rnuiiczs, but decidedly more so than in viyricce or mtri- 

 conia. The anal extremity is larger and rounder than in any of 

 the others ; an indication of the points, that are so evident in, 

 say, rninicis, may be detected, but they are somewhat uncer- 

 tain. The bristles are fewer and shorter than in the others, 

 and more easily lost, so that an impression that they are fewer 

 and shorter than inj truth they are, is readily formed. Some- 

 times they look as if they were dwindled spines, suggesting that 

 such may be the origin of these bristles. This appearance is 

 due to their being shorter and rather thicker than on the other 

 species, but on a closer examination it does not appear to be 

 really the fact. In Plate II., fig. 2 c, the nth segment is shown 

 without a spiracle, this is of course not the case : the artist's 

 intention, no doubt, is, that this segment is a mere sketch with- 

 out pretensions to accuracy, just as rumicis below (fig. 4c.) is a 

 mere outline except as to the anal armature itself. 



The cocoon is fuller and wider than the others, as suits a 

 more robust insect, the silk is dark, but paler than that of 

 rninicis, and otherwise its structure is the same as that of the 

 others of the group.

AcRONYCTA (Cuspidia) ALNI. WANTED. — Dr. Chapman has 

 unfortunately lost his brood of Cuspidia alni this year. As 

 there are still a few minor items of structure, etc., to be worked 

 out, he would be thankful to any one who could supply him with 

 the species in any of the earlier stages, and would make any 

 return in his power. — Ed.
