is mottled and marked with black. Tubercles i and ii wholly black, ill, iv, and v 

 black with a whitish centre, others black. Tubercle iii is widely circled with the 

 ground colour of the body, and in most specimens on the posterior four or five 

 segments. This is tinted with orange. Bristles from tubercles i and ii mostly black, 

 from iii and lower tubercles nearly all yellowish or reddish. Spiracles light yellow 

 ringed with black. Thoracic feet black at apex, reddish towards base; prolegs 

 outside upper two-thirds lilack, shining, lower third pale, seta; on feet pale reddish. 



Stafii' ^'■ — Length 10 umi. Larvje in general appearance much as in previous 

 stage. Head 2 mm. wide, same colour and marked as in Stage IV. Under the lens 

 the skin of body is greyish-green, varying in intensity of these colours, marked with 

 s|ilashes or blotches of black, principally on dorsum. Dorsal stripe yellowish or 

 whitish and faint. Tubercles i and ii black, shining; other tubercles whitish. 

 Bristles faintly but distinctly barbed, from 1 and ii mostly black, remaining ones 

 yellowish or rust-red. Bristles from iii and lower tubercles yellowish or rust-red 

 and black, the reddish ones greatly predominating. Spiracles yellowish, rimmed with 

 black, close to upper anterior edge of iv. Tubercle iii on four posterior segments is 

 rather widely margined anteriorly with orange, llauy of the tubercles also bear 

 long, slender, silvery bristles. Thoracic feet pale reddish. 



t<ta<je TV. — I./ength 24 mm. Head 2..5 mm. wide, soniewliat ipiadrate. slightly 

 indented at vertex, flattened in front ; yellowish-brown excepting front, which is 

 dark reddish, almost blackish in some specimens, shining; anteclyi)eus, labrum and 

 anteun:B yellowi.sh-white, mandibles dark reddish, setffi yellowish, long and slender. 

 Skin of bod.r almost wholly black, i.e., greyish-green ground colour densely blotched 

 and marked with velvety black, or very dark purple. The dorsal stripe has 

 disappeared in most specimens, in .some it is only present on anterior segments. 

 Tubercles large (i about one-third the size of iii. in some individuals all whitish, 

 but in most specimens tubercles i and ii are black, the remaining ones whitish. In 

 some larva' tubercles iii, iv, v. vi, vii, and viii are black at base, whitish at summit; 

 in others tubercles vii and viii are wholly black. The bristles from the tubercles of 

 most specimens are as in Stage Y., but in a few examples all of the bristles from all 

 tubercles are of a pale rust-red colour. Spiracles pale yellowish, black-rimmed. On 

 segments 6 to 13, inclusive, a red patc-h occurs before tubercle iii, very conspicuous 

 in some specimens, particularly on posterior segments. Thoracic feet reddLsh, prolegs 

 also reddish, but paler, darkened exteriorly. 



On July LSth one larva began to spin its cocoon, and by .July 21st h.-ul changed 

 to pupa. The cocoon, which is thin, was spun between the leaves in the bottom of 

 the breeding-jar, the pupa being plainly discernible. 



Pupa. — Length 15 mm., width at widest part mm., dull reddish-brown;' 

 abdomen coarsely punctured ; wing-cases and thorax wrinkled ; spiracles pale yellow, 

 lilack-rimmed; cremaster short, blunt, bearing 12 short, capitate bristles of varying 

 lengths. 



SNOW-INSECTS. 



By .T. William Cocklk. Kaslo, B.C. 



The collecting nf entuniological specimeiLs is usually associated with llie warm 

 months of summer, when the ever-changing hues of gorgeous butterHies, the wldr 

 cif beetles, the singing of the niosipiito, and tlie lium of bees and flies presents an 

 . ver-chauging scene before the collector's eye. But allow me to draw your attention 

 for a few minutes to what may be found on a winter day. when the thermometer 

 is down to near freezing-point and the snow lies thick on the grmnid. 



First let me introduce to your notice the snow-fleas of the genus Aplioiiira. 

 Passing over the common blac-k species of tills genus, which may be .seen in abundance 

 on the melting snows in the spring, and which frecpient water-holes and other damii 

 places during the summer months, breeding in soft humus, we next come to one 

 species which is only known to exist at Kaslo. Dr. Folsom lias given tills species, 

 wliicb is closely allied to .1. ■■<ih<-ricii. the name n( .1. rncl-Ui. It is a beautiful
