Ptiliam.'] clavicornia. 133 



Allied to tlic prcccdinj:,^ but easily distinguished by its smaller size, 

 broader form, shorter elytra, and reddish or castaneous colour ; the 

 sculpture is exceedingly fine, and the thorax is narrower in proportion to 

 the elytra ; the antennae, also, are rather shorter, and have the last joints 

 more thickened. L. | mm. 



In WQsis oi Formica rn-fa ; locally abimdant ; Chislehurst, Kcufc; Scarborough; 

 Scotland, very local, Due and ]\Ioray districts. 



P. insigrne, Matth. Elongate, rufo-castaneous, clothed with short 

 pale pubescence, rather finely and closely tuberculate ; head large, 

 elongate in front, antennae pale yellow, short and stout, with the two 

 last joints much thickened ; thorax short, with sides strongly rounded, 

 and much constricted at base, with a deep central channel and a shallow 

 impressed line on each side, the channel and lines being parallel; elytra 

 lather long, not dilated behind ; abdomen plainly exsertcd, testaceous ; 

 legs rather long, slender, pale yellow, tibiaa dilated at apex ; under- side 

 entirely testaceous. L. | mm. 



Very rare ; one example has been t;ilcen by Mr. WatcrhoMse in the London district, 

 and Mr. Blatcii records it as from " Knowle(?)" in lawn clippings. 



This species, like P. ajfme, has the lateral lines on thorax parallel to 

 the central channel, but they are much shallower, and the insect is 

 altogether smaller and narrower, and more hnely sculptured, and the 

 thorax is broadest about middle. 



P. foveolatuiiHj All. {excavaium, Er. ; clandedinuvi, Hal.; 7nini- 

 vimn? Herbst.). Elongate, very small, narrow, and slender, rather 

 convex, rufo-castaneous or rufo-testaceous, clothed with short yellow 

 liairs, strongly and closely tuberculate ; head large, almost triangular, 

 very much elongate, eyes large, prominent, anteunre rather long^ pale 

 yellow ; thorax not broader and scarcely longer than head, slightly rounded 

 in front, and constricted behind, with a short central channel and an 

 indistinct impressed line or fovea on each side diverging in front ; these 

 impressed lines are sometimes very indistinct ; elytra long and linear, 

 pai allel-sided until near apex ; legs pale yellow, tibiie slightly dilated at 

 apex ; under-side rufo-testaceous. L. |-| mm. 



In dung-heaps, hot-beds, &c.; probably generally distributed; Kingsgatc ; Mid- 

 land districts ; Korlbumberlaud district, rare; I have taken it in the greatest pi o- 

 fusion in a hot-bed at Bainwood near Gloucester; when a hot-bed is freshly watered 

 and closed the evaporated steam condenses in large drops on the under-surf.iee of the 

 glass; various species of small beetles, especially Trithopterygidas, are perpetually 

 fiyiug upwaids from the cer^tre of the bed, and these are caugiit in the drops and may 

 be sometimes taken by the hundred; I obtained all my specimens of P.foveolatiun 

 in this manner. 



P. Kalidaii, Matth. Elongate-oval, slender, very convex, shining, 

 bright castaneous, sparingly clothed with very short pale pubescence ; 

 head moderate, rather elongate, deeply impressed with foveolate punc- 

 tiu-es, antennaj rather long, clear yellow ; thorax small and short, scarcely
