PINE. 
the skin appears wrinkled across and covered with very short stiff 
black hairs.” * 
By June 23rd a number of the caterpillars sent had formed their 
cocoons. These were rather more than a quarter of an inch in length, 
cylindrical, bluntly obtuse at each end, the colour pale ochrey.f Some 
of the cocoons were placed on the Pine twigs, and some on the sides 
of the box, either singly or up to as many as four cocoons together. 
On the 9tli of August (or previously), the imago was appearing, as I 
then found it alive as well as dead in the box. These Sawflies proved 
to be of the L. rufus, Klug. They are of the shape figured, magnified, 
at p. 118, and the following description of them is given in Stephens’ 
‘ Entomology ’:— 
“Male, with body depressed, somewhat linear shining black; 
abdomen beneath (except the apex), and the legs, testaceous red ; 
antennae twice the length of the thorax, sword-shaped with 25 
rays on each side, and a simple joint at the apex; wings hyaline, 
anterior with a faint brownish stigma. 
“ Female, with the body subcylindric, elongate, and entirely of a 
testaceous red; antennae black, 23-jointed, the 2 basal joints testaceous. 
“ The thorax and the base of the abdomen are occasionally spotted 
a little with black. Length of body of male 3-|, of female 4 lines. ” \ 
The time of appearance of the perfect insect is noted as from about 
the end of August to October. Hartig mentions that he bred the 
Sawflies in the middle of September, from liybernated cocoons (of 
course of the previous winter) collected from beneath Moss; from 
caterpillars which fed on the young Fir, and spun up at the end of 
June, the Sawflies appeared in one instance in the beginning of 
October, in another at the end of August. 
The eggs are stated by Kollar to be laid in the Fir leafage, in the 
same manner as those of the Common Pine Sawfly. That is, that the 
female makes a slit with the saw-like ovipositor (from which the Sawflies 
take their name) along the Pine leaf, and in the narrow hollow she 
lays the eggs, which she then covers up with a mixture of a tough 
resinous material and substance scraped from the leaf. From the 
observations of Hartig, Taschenberg and Kollar, there only appears 
to be one brood of caterpillars, that which is found on the trees towards 
* These caterpillars vary in marking with age and condition, as—whether the 
caterpillar has lately changed its skin or is about to do so. My specimens varied 
much, but in essentials agreed with the descriptions of Hartig and Kollar, and may 
be distinguished by the above notes of colouring from those of the Common Pine 
Sawfly, noticed in previous Keports.— Ed. 
f This colour is described by Hartig as “ a clear yellow, with more or less of a 
red tint sometimes appearing through it.”—* Die Blattwespen und Holzwespen,’ von
