GEOTRUPIDTE. — GEOTRUPES. 185 



punctures, the lateral margins very thickly punctured, with a fovea towards 

 the middle: scutellum smooth, with an impressed dorsal line: elytra moderately 

 convex, slightly elongate, punctate-striate, the interstices smooth, depressed : 

 legs violaceous-black ; tarsi pitchy-black : antenna with the club slightly cas- 

 taneous or rusty-piceous. 

 Variable in bulk , but not much in colour :— and may be at once known from its 

 congeners by the deeply impressed puncta on the thorax, combined with its 

 distinctly punctate-striate elytra, with depressed interstices, in which latter 

 characters it differs from Ge. sylvaticus, niger, and Irevis, which have the thorax 

 more or less punctate throughout; but these insects are of a totally different 

 form. 



Not very abundant within the metropolitan district, but apparently- 

 more so near Bristol, whence I have received many specimens : it 

 also occurs in Wales. " Cooms-wood, Armatliwaite." — T. C. Hey-

Ge. sublsevigatus mihi.—Steph. Catal. 107. No. 1113. 



Oblong-oval : deep violaceous-black, with the lateral margins of the thorax and 

 elytra purple : clypeus slightly rugose, with an obsolete central tubercle : 

 thorax moderately convex, the disc smooth, with an interrupted punctate 

 dorsal channel, the sides rather thickly and deeply punctate, especially on the 

 margin, where the puncta become confluent; on each side are two fovea;, one 

 deep punctate one externally, and a smaller impunctate one towards the disc ; 

 and towards the middle of the anterior margin are also two other rather large 

 impunctate depressions, equidistant from each other and the lateral margins : 

 scutellum rugose in the centre : elytra finely striated, the strife composed of 

 distinct punctures, the interstices depressed and smooth: body beneath vio- 

 laceous : legs the same : tarsi piceous : antennas with the capitulum rusty- 

 piceous. 



In form resembling Ge. stercorarius $ , but totally distinct from that insect, 

 from which its obsoletely striated elytra, with flat interstices, at once remove 

 it, and distinguish it from its congeners. 



My example of this conspicuous species was taken by myself, 

 many years since, in the neighbourhood of London, but I do not 

 remember the exact locality. 



Sp. 10. stercorarius. Obion go-oval is, niger, infra violaceus, vertice tuberculo 

 acuto, thorace Iwvi, lineCi dorsali abbreviate impressft, elyfris profundi striatis 

 striis imprcsso-punctaiis. (Long. corp. 8 — 12 lin.)
