Thorax — Pronotitm in the middle and on the posterior margin pale ochreotis, the 

 remainder of the disc fuscous. Scutellum pale, sometimes with an obUque 

 fuscous streak on each si'de. Elytra delicately punctulate. Clavus fuscous, 

 the base broadly, the inner margin narrowly, and the claval-suture indis- 

 tinctly, pale ochreous. Corium with 3 long, fuscous, longitudinal streaks, 

 of which the longest is on the posterior inner angle, the other 2 shorter, 

 less distinct, on the middle of the disc, all 3 more or less confluent ; anterior 

 margin pale, with a long fuscous streak in the middle, and one before the 

 apex. Membrane pale, fuscous in the middle and inwardly. Logs ochreous, 

 posterior tarsi with brown cilia. Length rather more than 1 line. 



Distinguished from S. minutissima especially by its larger size, 



greater breadth of the head, and lighter colour. Varies according to 



maturity in the darkness of the markings, very young examples being 



almost wholly pale. 



A few examples were taken by Dr. Power, at St. Leonard's Forest, 



Sussex, in 1866.

Note on the oviposition of Octotemnus glahricuhos. — Last autumn, I had a portion 

 of a thick white tough fungus {Polyporus containing this beetle abun- 

 dantly, several of them being engaged in oviposition. The female beetle by herself 

 makes a sinuous gallery of rather more than her own width ; the eggs, each of 

 which is of a somewhat flattened ovoidal form, its longest diameter being about 

 one-fifth the length of the beetle, are laid at the bottom of little cavities, ii-regularly 

 disposed along the sides of the burrow. The egg, laid on its flattened side, just fits 

 the bottom of the cavity ; the remainder of the cavity, which is wide towards the 

 burrow, is filled up level with its wall with the finely comminuted fragments of 

 fungus removed from the end of the bm'row, and so firmly packed, as easily to come 

 out in one mass ; six was the largest number of eggs I found so placed along one 

 burrow, but I had no reason to suppose this to be the full number, as the beetle 

 was still at work. Having placed some beetles on a fresh portion of fungus, I 

 found, at the end of a week, that a newly -formed burrow contained three eggs. —

Note on the pairing of Cheiropachus quadrum. — Some months ago I picked up a 

 few branches broken from an apple tree, which were completely infested by Scolytus 

 rugulosus ;* beneath the bark were numerous Chalcididous larvae, which had preyed 

 on the ScoVyti, so numerous, that they must have destroyed quite half of them. 

 Having kept them in a warm room, though the Scolytus is only just beginning to 

 appear (April 8th), the parasites emerged during February ; they were chiefly 

 Cheiropachus quadrum, of which a dozen or two came out every day for some time. 

 As the opportunity of making the following observation cannot be frequent, I think 

 it is probably worth recording. 



I shall be happy to send the Scolytut to any one who will enclose return postage.— T. A. C.
