Forest; Repton ; Buxton; Withington, Cheshire ; SootLind, very rare, Solway and 

 Forth districts; Ireland, one specimen, near Dublin (Egaii). 



V. Leachii, Curt, (ad/istus, Kiist.). This variety is a little narrower 

 than the type, especially at the elytra, and the elytra have the whole apex 

 or at least the posterior angles more or less broadly darkened. 



This variety sometimes occurs with the type, but as a rule they are 

 found in different localities ; Tonbridge ; Hythe ; Barmouth ; Bewdley 

 Forest ; Scarborough ; Preston Marsli, Lancashire ; Stretford, near Man- 

 chester ; Carlisle ; Scotland, very rare, Solway and Forth districts. 



HOMALIIN^. 



This sub-family contains upwards of forty genera, of which by far 

 the largest in point of numbers is Homalium ; this genus, however, is 

 by some authors split up into seven or eight sub-genera ; the great 

 characteristic of the sub-family is the presence of two ocelli or simple 

 lenses on the vertex of the head, which are usually placed on a line 

 joining the posterior margins of the eyes ; the anterior coxa? are conical 

 and prominent, and the posterior ones transverse ; the body, as a rule, is 

 flat and the elytra often cover a great portion of the hind body ; all the 

 tarsi are five-jointed ; very little appears to be known as yet regarding 

 their transformations. 



The following arrangement of the genera must be regarded as more or 

 less provisional, as it is rather hard to arrange them satisfactorily : — 



I. Maxillary palpi with the last joint very minute, 



subulate ; penultimate joint very strongly dilated. 

 i. Posterior tarsi with first and second joints rather 



longer than the two following ; antennse more 



slender CoRTPHiUM, Sfeph. 



ii. Posterior tarsi with joints 1-4 about equal in 



length ; antennse shorter and stouter EUDECTITS, Redt. 



II. Maxillary palpi with the last joint more or less 

 elongate ; penultimate joint not, or only slightly, 



dilated. 

 i. Posterior tarsi with joints 1-4 unequal in length. 



1. Posterior tarsi elongate nearly as long as 



tibiae PniiOEniNUM, Kraatz. 



2. Posterior tarsi distinctly shorter than tibiae. 



A. Maxillary palpi with the last joint four 



times as long as the penultimate .... Lesteva, Latr. 



B. Maxillary palpi with last joint equal to or a 



little longer or shorter than penultimate. 



a. Mandibles strongly denticulate with the 



tei th long and sharp. 



a*. Maxillary palpi with penultimate 



joint not dilated Anthophagus, Orav. 



b*. Maxillary palpi with penultimate joint 

 distinctly, although not strongly di- 

 lated, pyrifonn, plainly broader at apex 

 than last joint Geodbomictts, Redt. 



b. Mandibles quite simple, or at most with 



a trace of a blunt tooth at apex.
