slender tarsi, smoother elytra, and a smooth bare space down the middle of the 

 nietasternum. In O. meidllesrens {poireri) the tarsi are eomparatively stout and 

 the metasterni^m is closely pubescent throug'hout. Cleaned specimens of the 

 latter show the rows of minute squamiform hairs on the elytra, which are indeed 

 noticed by Rye, thoiigh he did not oliserve the uniform metasternal vestiture of 

 the single example upon which his description was based. In ail three species 

 { 0. metallescens, 0. foveolatus, and 0. dentifer) the anterior angles of the pro- 

 thorax are sharp and prominent. Various other members of the genus have an 

 equally wide distribution, our somewhat local 0. exaratus Muls. and 0. punctatus 

 Steph., as well as the common 0. impressicollis Lap., extending to the Mediter- 

 ranean region and Marocco. — Geo. C. Champion, Horsell, Woking : October I2t}t,

Xylophilus immaculatus Champ. : a change of name. — Since the publication 

 of my paper on the Bornean Xylophili (anten pp. 278-288), the proofs of which 

 were corrected in iJevonshire, a preoccupied specific name, immaculatus (I.e., 

 p. 285), has been detected. Lea having already iTsed the same name (under 

 Syzeton, a synonym of Xylophilus) for an Australian insect : immaeulipennis is 

 here substituted for the Bornean species. — G. C. Champion : October, 1915. 



Prionus coriamts F., in Epping Forest. — On Janiiary lOtli, 1915, while ex- 

 amining a log of oak in Epping Forest, I found a small larva of a Longicorn 

 beetle in a burrow between the bark ami the actual wood of the tree. Further 

 investigation revealed the presence of three full-fed larvae, which, through the 

 kindness of Dr. C. J. Gahan, were identified as Prionus coriarius F. Since then 

 I have on foui" occasions taken larvae from oak logs in the same locality. In 

 all, I took 20 specimens, 17 of which were quite mature. The Ijurrows made 

 by the larger larvae were about one inch in breadth, and directly under the 

 bark, but those of the younger individuals were in the wood itself. The 

 longest burrow I observed was more than two yards in length, and the larva 

 was still boring. The galleries were simple, there being no ramifications, as is 

 the case with the tunnels of the smaller Longicorn Bhagium Inquisitor F., a 

 beetle I have always taken from logs attacked by Prionus. In July, on re- 

 visiting the place where larvae had occurred, I found seven pupae. Some of 

 these were in the log itself, and others in the ground immediately below the 

 log. In both cases, however, a cocoon of chips of wood, etc., had been formed. 

 The lining of the cocoons found in the ground was of clay. On September 5th 

 I took a dead specimen of the imago under a hornbeam log lying in a dry ditch 

 not far from the original locality ; the specimen was a female and only slightly 

 damaged. The particulai' part of the Forest in which I have taken larvae and 

 pupae of Prionus is restricted to an area of less than one acre. Although there 

 is here a preponderance of beech timber, only oak appeared to be attacked. 

 My thanks are due to Mr. G. W. Thomas for rendering great assistance in 

 collecting the larvae and pupae. — Harold E. Box, 86, James Lane, Leyton, 

 Essex: October I2th, 1915.
