T. Sarce differs from every other European species in size, shape, 

 and colour, in the great development and peculiar sculpture of the 

 thorax, in the shortness of its legs, and the elongation of the apical 

 joint of its antennae. 



Two specimens only were taken five years ago in Nottinghamshire 

 by my brother, the Eev. H. Matthews. I have named this fine species 

 in honour of Mrs. Matthews, by whom two species, Ptin. Maria and 

 Trichopteryoc littoralis, have been added to the British list, and a third, 

 Ptilium myrmecopliilum, taken for the first time in England. 



Trichopteryx Waterhousii, n, s. 



L. c. le lin. Oblonga, sub-parallela, aliquantum depressa, nigro- 

 fusca, elytris testaceis, pilis brevibus pallidis vestita ; capite magno, 

 prominulo ; pronoto sat brevi, vix postice dilatato, tuberculis minutis 

 distinctissimis, ordinibus den sis irregulariter dispositis, interstitiis 

 leviter alutaceis omato, angulis posticis aliquantum productis ; elytris 

 brevibus, quadratis ; pedibus atque antennis flavis. 



Sead — large, dull black, alutaceous ; eyes moderate, not prominent ; 

 antennse moderate, bright yellow, with the apical joints but little 

 incrassate. 



Thorax — dull black, short, quadrate, scarcely dilated posteriorly, with 

 the sides very slightly rounded ; covered with small distinct 

 tubercles, irregularly arranged in close rows, with the interstices 

 slightly alutaceous ; posterior margin yellow, reflexed, scarcely 

 depressed, and deeply sinuated, with the angles slightly produced. 



Scutellum — dull black, large, triangular, very slightly asperate. 



Elytra — short, quadrate, testaceous, not longer or wider than the head 

 and thorax united, slightly dilated towards the apex, with the 

 sides nearly straight, lightly asperate in rather distant transverse 

 rows ; apex wide, and very little rounded. 



Abdomen — fuscous, moderately exserted. 



Legs — rather long, bright yellow. 



Under parts — piceous, with the metasternum and abdomen paler ; 

 mouth and coxa; yellow. 



The ouly two examples of this species which I have seen were 

 taken many years ago by Mr. Waterhouse : locality unknown. 



T. Waterhousii is allied to T. Chevrolatii and T. Ouerinii, but may 

 be known from these, and all other species of the genus, by the size, 

 shape, and colour of the body, and by the sculpture of the thorax.
