Atomana.] olavicornia. 343 



tlie colour is nigro-f uscous or deep-brown with the apex of elytra lighter, 

 the colour extending more or less towards base ; antennae red ; thorax 

 transverse, very closely but distinctly and rather deeply punctured ; 

 elytra broader than thorax, dilated in middle, with distinct and rather 

 diffuse punctuation ; legs testaceous. L. l^-H mm. 



In haystack and other refuse, hot-beds, &c. ; somewhat h)cal, but rather common 

 and generally distributed throughout the southern and midland districts of England ; 

 Yorkshire ; Manchester district ; Bold records it as common in the Northmnberland 

 district, but it is rare in Scotland, and has only occurred hitherto in the Moray dis- 

 trict ; Ireland, near Waterford. 



From A. fuscuta, which perhaps it is most often confounded with, this 

 species may be distinguished by its shape, the less rounded sides and bi- 

 sinuate base of thorax, and the somewhat stronger punctuation. 



A. analis, Er. {iestacca, Rteph.). Oblong-oval, slightly convex, 

 clothed with fine greyish pubescence, black with the apex of elytra 

 rather brightly reddish-testaceous, the colour in mature specimens not 

 extending beyond posterior third ; antennae ferruginous or brownish-red ; 

 thorax not strongly transverse, with sides feebly rounded, rather strongly 

 and distinctly punctured, basal impression deep ; elytra elliptical, wuth 

 punctuation somewhat variable, according to sex, but, as a rule, rather 

 strong and distinct ; legs brownish with the tarsi and base of tibiae, and 

 sometimes the whole tibiae, testaceous. L. If mm. 



In haystack refuse, manure-heaps, &c. ; rather common and generally distributed 

 throughout England, although somewhat local ; Scotland, local, Forth, Clyde, and 

 Dee districts. 



A. ruficornis, Marsh, {terminata, Com.). In colour and general 

 appearance this species very closely resembles the preceding, but it is 

 considerably smaller, and has the elytra less distinctly punctured and 

 the shoulders more rounded ; the antennae also are shorter and more 

 robust, and the thorax is rather more plainly produced posteriorly in 

 front of the scutellum ; the colour of the antennae and legs is also, as a 

 rule, lighter. L. H-IJ mm. 



In the midland and southern districts of England this species is exceedingly common 

 in manure-heaps, haystack refuse, dead birds, &c. ; it appears however, to be rarer 

 further north, and is not recorded from the Northumberland and Durham district 

 (the specimens from the locality supposed to belong to this species having been proved 

 by Mr Bold not to belong to the genus Atomana, at all); Scotland, rare, Solway, 

 Tweed Forth, and Clyde districts ; Ireland, near Waterford ; it is probably distri- 

 buted over the whole kingdom, except perhaps the extreme north of Scotland. 



A. versicolor, Er. {orriata, Heer). Oval, somewhat oblong, convex, 

 shining, clothed with fine and rather sparing ashy pubescence, colour 

 rufo-piceous, or rich brownish-red with the shoulders and apical region 

 of the elytra more or less broadly and clearly rufous or rufo-testaceous, 

 thorax usually darker ; antennae red, thorax not very transverse with 

 sides slightly rounded, plainly bisinuate at base, diffusely and distinctly
