42 Mr. R. M‘Lachlan’s Monograph of the 
termination of the sixth and seventh apical cells, and another 
about the arculus; some of the veins regularly spotted with black 
and white. Posterior wings hyaline, apex pale grey; veins tes- 
taceous, the ramus discoidalis and ramus subdiscoidalis fork at 
about the same distance from the base. Legs testaceous, with 
black spines, the thighs and the apices of the tibiz and tarsi 
somewhat fuscous. Abdomen dark fuscous above, ochreous be- 
neath, and with narrow ochreous lateral lines. In the male the 
upper margin of the last abdominal segment is not produced ; 
app. sup. spoon-shaped, obtuse, yellow; app. intermed. pointed, 
straight, lying against each other, not diverging ; app. inf. large, 
yellow, concave exteriorly, and with two shining black teeth at 
the apex. In the female there is in the middle a twice-divided 
tubular piece springing from a broad base; on each side of this is 
an appendage very similar in form to the app. sup. of the male, 
and below these on each side a broad obtusely rounded lateral 
valve. 
Expanse of fore-wings 10—11 lines. 
Larva grey, with lateral lines and a depressed dorsal line, 
brown, the anal segment with long black hairs, respiratory fila- 
ments white; head yellowish-brown, with an oblong median spot 
formed of eight or ten piceous dots, occiput with an oblique line 
on each side connivent posteriorly (vitta postice connivente), formed 
of piceous dots arranged more or less in rows ; pronotum and 
mesonotum yellow, the posterior and lateral margins with nume- 
rous piceous dots; metanotum with four corneous scales; legs 
yellow, the joints narrowly annulated with piceous. (Iolenati.) 
Case sometimes composed of pieces of grass or leaves placed 
obliquely, sometimes of stones; cylindrical. (Kolenati.) 
This very variable and widely-distributed species would appear 
to be far more common on the Continent than in this country. 
It appears in May and following months ; and most of the spe- 
cimens that I have taken have been beaten from fir trees in 
heathy districts ; apparently most common in the New Forest. 
I have seen an example from Haiti, and possess another from 
the river Amoor ; both of these resemble European specimens in 
every particular.
