78 THE entomologist's record. 



all the trapezoidal tubercles brilliant orange. The hairs vary 

 from entirely black in a few of the darkest to orange on the 

 trapezoidals. In most of them the lateral hairs are cinereous. 

 In a large well-marked specimen the subspiracular and mar- 

 ginal tubercles are surrounded by a greenish yellow line or 

 ring, and there are a few scattered marblings tending to con- 

 nect these into a longitudinal lateral line. Each tubercle has 

 twenty-two to twenty-five hairs, half the diameter of the larva 

 in length, except the post-spiracular, which is a mere dot. 

 Amongst the varieties, some of the darkest specimens have the 

 orange markings replaced by lemon yellow, and one specimen 

 is entirely black, except the orange tips and hairs of the trape- 

 zoidals of 4 and 6 to 13, the hairs of 5 being also orange. 



These larvae were hatched on May 22nd ; on June igth many 

 were laid up for fourth moult, and it is noted that of these 

 some few are nearly three times the bulk of others, certainly 

 much more than twice ; they are nearly one-fourth longer, and 

 nearly twice as thick; length respectively 11 mm. and 15mm,, 

 diameter 2|- to 33- and 3 to ^h mm. The event proved that 

 these large larvae only moulted four times, passing now into 

 the last skin, whilst the majority moulted five times. 



In the fifth skin the form is still that of runiicis, i.e., with 

 large 5th and 12th segments, and they are much more uniform 

 in colour than in the fourth skin. The larva is black, with the 

 trapezoidals of the segments from the 4th backwards, orange 

 golden ; slightly also the dorsal tubercles of the 3rd ; in most 

 the space between the trapezoidals is also orange, in 6.7, 10. 

 II, and the incision between 12 and 13 also. The variations 

 are for the posterior trapezoidals to be black, especially in 5, 8, 

 and g; and for the orange on 10 and 11 to be a broad, con- 

 tinuous streak across both segments. The posterior trapezoi- 

 dals are the smallest tubercles, the length of the hairs is little 

 more than half the diameter of the larva. The hairs on the 

 tubercles have not the tufted stellate aspect that they have in 

 menyantJiidis ; this appears to be due to some extent to the 

 tubercles being flatter, not so rounded and knobbed as in 

 menyantJiidis, but chiefly to the colouring, the dorsal hairs 

 being red, the lateral pale cinereous, but with a sprinkling of 

 black ones, and also there being some longer hairs interspersed, 

 especially in front and on the 12th segment. 



June 28. In last skin the full-fed larva is very handsome, 

 being black, with a double dorsal row of orange red tubercles, 

 and hairs of the same tint. At first it suggests H. dispar, but
