X80 [January, 



in Thoresby Park, in Nottinghamshire, in August, 1868 ; since then 

 I have waited in vain for the occiu'rence of other specimens, but 

 have now determined to separate and describe it as a distinct species 

 on the strength of the very essential characters which I have pointed 

 out. 



Teichopteeyx L^titi^, n. s. 



L. c. T5 lin. Ohlongo-ovalis, modice coniiexa, nigra, Timid nitida, 

 pilis pallidis dense vestita, capite modico ; pronoto sat parvo, posfice 

 dilatato, ad hasim latissimo, tiiberculis minutis, ordinibus transversis 

 irregulariter dispositis, interstitiisque profiinde et confertim reticnlatis 

 sat dense ornato, margine hasali sitmata, angiiUs acutis vaJde productis ; 

 elytris plus minusve attenuatis, capite atque pronoto vix Jongio'rihus aut 

 latiorihus, confertim asperatis, laterihus fere rectis, apicihus rotundatis, 

 dilutiorihus ; pedihus ohsoureflavis, antennis piceo-nigris. 



Head moderate, triangularly produced in front, sparingly covered with minute tuber- 

 cles, the interstices shining ; eyes large and prominent ; antennfe short and 

 slender, pitchy-black ; palpi pitchy-black. 



Thorax rather short, not very convex, rather longer than the head, dilated poste- 

 riorly, widest at the base, with the sides moderately rounded and margined, 

 covered with miniite tubercles closely arranged in transverse wavy rows, with 

 the interstices closely and rather deeply reticulate, the basal margin rather 

 strongly sinuated, with its angles acute and much produced, the extreme edge 

 of the sides and base pale. 



Scutellum large, triangular, rather acuminate, closely, but not deeply, asperate. 



Elytra oblong, more or less strongly attenuated towards the apex, scarcely longer 

 or wider than the head and thorax, moderately but closely asperate in trans- 

 verse rows, with the sides nearly straight, the apex much rounded, paler, with 

 its extreme edge white. 



Abdomen much exserted, obtusely conic, with the posterior margin of each segment 

 paler, and the apical segment distinctly but obtusely tridentate. 



Legs moderate, dusky yellow, with the basal joint of the anterior tarsi slightly 



dilated. 

 Under-parts black, with the mouth and coxse piceous ; femora dusky. 



Allied to T. fascicularis, Herbst, but differs from that species in 

 its smaller and more depressed thorax, shorter and pitchy-black an- 

 tennae, and in its conspicuously smaller size. It was found in large 

 numbers, unmixed with any other form, by my sister, Miss L. 

 Matthews (after whom I have named the species), in Belgium, near 

 Spa, in August last. 



Gumley : November, 1872.
