Robin's Wood ; Chat Moss ; Stretford, near Manchester ; Northumberland district, 

 generally distributed but nowhere common, Walliugton, &c. ; Scotland, rare, Solway, 

 Tweed, and Forth districts; Ireland, near Dublin (Power). 



A. silaceus, Herbst., 7iec Gyll. This species most closely resembles 

 A. nigricornis, but is rather smaller, and is at once distinguished from 

 it by the very long tomentose pubescence, which is especially marked 

 on the head, and also by having the anterior tibia produced into a 

 strong tooth at apex ; the anterior angles of the thorax also are some- 

 what callose, and the tibiae of the male are, apparently, less fuscous at 

 apex ; the male characters appear to be much the same ; from A. 

 yaJlens it may be distinguished by its lighter colour, larger size, much 

 more marked pubescence, and the stronger tooth at apex of anterior 

 tibise. L. 3|— i mm. 



By sweeping ; probably also associated with Bomhi ; rare ; Darenth Wood, Reigate, 

 Hornsey, Caterham, Chatham, Gravesend; Ashwicken ; Deal; Folkestone; Bourne- 

 mouth ; Plymouth, Whitsand Bay (J. J. Walker) ; Coleshill ; Bromsgrove ; Hun- 

 stanton ; Oxfordshire ; not recorded from the northern counties of England or from 

 Scotland or Ireland ; the A. silaceus of Murray's catalogue must without doubt be 

 referred to A. nigricornis. 



CRVPTOPKAGUS, Herbst. 



This genus comprises about a hundred species, which chiefly occur in 

 the temperate regions of the Old World, more than half of them being 

 found in Europe ; the genus is, hoAvever, Avidely distributed, and will 

 probably be found to consist of a mu.cli larger number of species than 

 it does at present, a^ representatives have been found in South Africa, 

 New Zealand, and other localities ; the members of the genus have the 

 posterior tarsi 4-jointed in the male ; they are small insignificant-lookino- 

 insects, usually of a reddish-brown colour, and are exceedingly closelv 

 allied, so that it is very hard to determine them except by comparison 

 with authentic types ; they are found in all sorts of localities, such as 

 rubbish-heaps, hot-beds, cellars, and outhouses, in moss, fungi, &c. • 

 many of our species are very common, but some are exceedingly rare, 

 and it is hardly settled yet how many we really possess ; the tables 

 given below may to a certain extent be found useful, but must be 

 regarded as merely provisional, and must not be relied upon apart 

 from the separate descriptions ; the species may roughly be divided into 

 the following sections : — 



I. Thorax with the sides crennlate, furnished with a distinct tooth in or about 

 middle. 

 i. Antennae with the first joint of club nearly as broad as the following ones. 



1. Upper surface strongly and not closely punctured, with more or less distinct 

 outstanding seta3 ; thorax with four smooth prominences, two at sides of 

 disc and two at base. 



Section I. C bjcojwdi, sehilosus, Schmidtii, pilosus, punctipennis, 



mficornis.
