Ptenidium.~\ CLAVICOENIA. 141 



and very broad, distinctly punctured in rows, wings black visible in 

 some specimens beneath elytra ; legs long, yellow, tibiae slightly dilated ; 

 under-side rufo-piceous, mouth, coxse and abdomen lighter. L. 1-1 j 

 mm. 



In rotten wood, usually in company with ants ; rare ; Strood, Kent (Champion) ; 

 near London, 1862 ( Waterhotue) ; Cobham Park ; New Forest (Sharp and Qorham) ; 

 Scarborough (Wilkiuson) ; Mr. Blutch has also taken it in the New Forest in 

 fungi. 



This species may easily be known by its obtuse and turgid shape and 

 the shining pitchy-red colour of the whole body. 



P. Gressneri, Er. Entirely oval in shape, with the thorax broadest 

 at base and continuous in outline with the elytra, a point which separates 

 it from our other species, which all have the thorax contracted at base ; 

 colour rufous or rufo-piceous ; head rather large, eyes small, antennae long, 

 clear yellow ; thorax short, glabrous, without basal fovese ; scutellum 

 short and broad ; elytra broad, ovate, broadest before middle, acuminate 

 behind, scarcely punctured ; wings black, usually visible underneath the 

 transparent elytra ; legs long, slender, clear yellow ; under-side rufo- 

 piceous, with head and thorax lighter, last segment of the abdomen, 

 coxse, and metasternum, yellow. L. - 1 mm. 



In rotten wood, chiefly in company with F. fuliginosa ; rare ; discovered by Mr. 

 TJhitch in June, 1883, in the New Forest in fungi ; and subsequently found by Mr. 

 Gorham and Dr. Sharp in the same locality ; Mr. blatch has since taken it in Sher- 

 wood Forest under bark. 



CORYLOPHID^l. 



The members of this family are very small, oval or rounded insects, 

 which approach the Trichopterygidse in having their wings fringed with 

 long hairs ; they differ, however, in having the maxillas unilobed and the 

 tarsi 4-jointed (the third joint being small, and concealed in an emargi- 

 nation of the second joint), and in the fact that the wings are much 

 shorter ; the maxillary palpi are also differently formed and are some- 

 times very curious ; the genus Aphgmocephalus, which appears to be 

 widely distributed in the East of Asia is now rightly separated by 

 Mr. Matthews, and regarded as a family distinct in itself, called Pseudo- 

 corylophidae ; the species of this genus have the maxillary palpi apparently 

 3-lobed, and the tarsi are truly 3-jointed ; the wings, moreover, are very 

 differently formed. 



The Corylophidae are universally distributed in the temperate and 

 tropical regions of the world ; at present seventeen genera and more than 

 150 species have been described ; the Eev. A. Matthews is at present 

 engaged on a monograph of the group, which, when completed, will be 

 almost as valuable a contribution to our study of the minute Coleoptcra 

 as his well-known " Trichopteryyia lUustrata;" we may, therefore, expect 

 that the number of species will be largely increased.
