TVPKHIA, Curtis. 



This genus comprises about half-a-dozen species from Europe, Ceylon, 

 and Cuba ; our single species, T. fumata, is very widely spread over the 

 Northern Hemisphere, and has been distributed by commerce, as it 

 occurs in granary refuse, &c. ; the larva is described by Perris, Larves 

 des Coleopteres, p. 89 ; it is very like those of the other Mycetophagidje, 

 and scarcely requires a separate description, except that it is more 

 lightly coloured, being almost white. 



T. fumata, L. Oblong-oval, rather depressed, with sides sub- 

 parallel, ferruginous or yellowish-red, with very distinct yellowish 

 pubescence ; head finely punctured, eyes black, antenna with distinct 

 3-jointed club ; thorax as broad behind as elytra, somewhat narrowed in 

 front, thickly and finely punctured, posterior angles almost right angles, 

 scutellum quadrangular ; elytra with fine punctured strijp, the interstices 

 being either finely punctured or slightly cross-striated, and each furnished 

 with a distinct row of long yellowish hairs; legs coloured as body. 

 L 2i-2| mm. 



In haystack and granary refuse, by sweeping, &c. ; common and widely distributed 

 throughout the greater part of England ; local in Scotland, Solway and Clyde 

 districts ; Ireland, near Dublin and Waterford, and probably common. 



TRIPKVZiXiUS, Latreille. 



This genus contains four or five species from Europe and JSTorth 

 America ; tney resemble Mycetojjhagus, but differ in their distinct antennal 

 club, and the confused punctuation of the elytra. Eeitter separates 

 T. suturalis and T. colchicus as a separate genus Pseudotriphyllus ; the 

 species are found in fungi. 



I. Thorax with a distinct basal fovea on each side ; length 



2^-2% ram. {Pseudotripliyllus, ViQitt.) T. sutuealis, F. 



II. Thorax without basal foveas ; length 4 mm. (Tripliyllus, 



i. sp.) . . T. PUNCTATUS, F. 



T. suturalis, F. Long-oval, clothed with fine, but distinct, greyish 

 pubescence ; colour somewhat variable, usually pitchy with the margins 

 of thorax and a greater or less portion of the elytra testaceous or red- 

 dish-testaceous ; head distinctly punctured, clypeus strongly marked, 

 antennje moderate, ferruginous, with distinct 3-jointed club ; thorax 

 somewhat narrower at base than elytra, broader than long, side margins 

 finely crenulate, all the angles blunt, upper surface distinctly and not
