this species was stated to have recently been discovered by Col. 

 Yerbury at Nethy Bridge, Inverness- shire. Since then it has been 

 bred in considerable quantity from larvse found in the large pines 

 at the same locahty, by both Dr. Sharp and Mr. Bishop, who 

 have also taken a few specimens at large. The more deeply cleft 

 third tarsal joint distinguishes it from the very closely allied C. 

 ferns, Muls., an insect found on pines during recent years in the 

 New Forest, and in August and September last near Woking 

 (Ent. Mo. Mag., xlv, pp. 247, 249). 



Fig. 6—Pachyta sexmaculata, L., ^^ .— This species was introduced 

 into our list in 1877 [Ent. Mo. Mag., xiv, pp. 92, 93], on the 

 authority of two specimens, captured by Mrs. King in the Eothie- 

 murchus Forest, at Aviemore, Inverness-shire. During recent 

 years it has been taken in some numbers at Nethy Bridge, by 

 Col. Yerbury, Dr. Sharp, Mr. Bishop, and others, and again at 

 Aviemore by Mr. Evans in 1893, and by Mr. King in 1903. In 

 the series taken by Dr. Sharp in 1909 there are several examples 

 with the angulated yellow elytral fasciae reduced to scattered spots. 

 Fully developed males have a conspicuous triangular tooth on the 

 inner edge of the posterior tibiae, beyond the middle, but in the 

 specimen figured (one of those taken in 1877) this tooth is so 

 small that it was not noticed by our artist when he drew the 

 plate. P. sexmaculata is a widely distributed Holarctic beetle 

 living upon pines, but it is apparently a rare boreal insect in 

 Europe. 



Fig. 7 — Tetropium gabrieli, Weise, var. crawshayi, Sharp, ? . — This 

 Longicorn beetle was described by Dr. Sharp in 1905 as a distinct 

 species, from a large number of specimens reared from larch, at 

 Leighton Buzzard, by the Eev. Gr. A. Crawshay. Subsequent 

 investigation by the last-named gentleman has shown that T. 

 crawshayi is simply a variety of T. gabrieli, with reddish tibiae 

 and tarsi and black femora. Mr. Crawshay has given a full and 

 interesting account of its life-history, distribution,* &c,, in the 

 Trans. Ent. Soc, London, 1907, pp. 183—212, pis. xv— xx. In 

 the wild state he says it is exclusively attached to Larix europxa. 

 The insect is likely to become destructive to larch plantations, as 

 it is evidently spreading m the midland and southern coimties.
