350 CLAVICORNIA. . [Triphyllu*. 



very closely punctured, base with a distinct fovea on each side ; elytra 

 strongly punctured in front, more finely behind. L. 2^ 2|^ mm. 



In fungi on old trees ; local ; London district, not common, Esher, Sheerness ; 

 Wicken Fen ; Salford Priors ; Repton ; Sherwood Forest ; Ripon ; Scarborough ; 

 Dunham Park, Manchester ; Northumberland district, Wallingtou, &c., recorded by 

 Bold as common in fungi ; the Scotch record, however, is " Tweed district only, very 

 rare." 



T. punctatus, F. Very like the preceding in general shape, but 

 twice as large and more coarsely punctured and pubescent ; the colour 

 also is brighter, as a rule, and the elytra are pitchy with the base 

 rather sharply testaceous, and with a testaceous patch before the apex 

 of each ; the thorax has no basal foveae, and the prosternum in the 

 female, which in the preceding species has a fovea on its front margin, 

 is in this species simple ; the club of the antennae, also, is more gradual. 

 L. 4 mm. 



In fungi on old stumps of trees ; common in the London district and the South, 

 and rather common in the Midlands, but rarer further north, and not recorded 

 from the extreme northern counties of England or from Scotland. Scarborough and 

 Dunham Park, Manchester, seem the most northerly localities from which it has been 

 recorded. ' 



LIT ARGUS, Erichson. 



This genus contains about a dozen species, which are widely distri- 

 buted over the surface of the world, species being recorded from 

 Madeira and the Canary Islands, North America, Peru, &c. ; there are 

 two European species, of which one is found very locally in Britain. 



The larva of If. bifasciatus is described and figured by Perris, Larves des Coleop- 

 teres, p. 84, PI. ii. fig. 65 ; it is 3 mm. in length, linear, rather depressed ; head 

 suborbicular, black with a central whitish line, antennae very short, 4-jointed ; 

 thoracic segments brownish-black, the prothorax larger than the following with a 

 fine central whitish line ; abdominal segments each with a broad band of brownish - 

 black, last segment small, bearing two small cerci, segments furnished with long setae 

 at sides ; under -side pale; this larva is found under bark of various trees, usually in 

 or about the burrows of Scolytus, but apparently feeding on fungoid growth. 



Xi. bifasciatus, F. (lunatus, F. ; signatus, Panz.). Elongate oval, 

 rather depressed, clothed with fine recumbent pubescence, upper sur- 

 face finely punctured ; colour black, with the hinder part of the margins 

 of thorax and two waved bands on elytra, together with a spot before 

 apex of latter, yellow ; the markings are somewhat variable ; the thorax 

 behind is fully as broad as elytra, transverse, narrowed in front, basal 

 margin bisinuate, posterior angles very distinct, projecting ; on each side 

 at base is a longitudinal impression ; elytra rather long, with sides sub- 

 parallel ; under-side finely pubescent ; legs reddish-yellow. L. 3 mm. 



Under bark of beech and other trees; local; Chatham; Maidstone; Westerham ; 

 Woodford ; New Forest ; Isle of Wight; Bristol: I have taken one specimen under 

 bark of elder nt Lincoln, which is considerably further north than any hitherto 

 recorded locality.
