allied to the preceding, which it resembles in colour ami general 

 appearance ; it is, however, smaller and distinctly more ovate, and may 

 be easily known by the regular simple rows of strong punctures on the 

 elytra ; the thorax, also, is more finely punctured, and tin; anterior 

 angles are less prominent ; the male is smaller, and has the last ventral 

 segment of the abdomen distinctly impressed transversely at base. L. 

 3-4 mm. 



On Urtica dioica, also on reeds, d>y grass, Ac. ; often found with the preceding; 

 common and generally distributed throughout the kiugdoui. 



C. ruflpea, L. (Derocrfpis rvjipeg, Weise). Oblong-ovate, convex, 

 shining, with the head, antennae, thorax and legs red, and the elytra 

 dark, nigro-coeruleous, cyaneous, or greenish ; abdomen and breast 

 black ; head scarcely punctured, thorax transverse, scarcely visibly 

 punctured, broadest at or just behind middle, narrowed in front, with 

 a distinct transverse furrow, bounded on each side by a strong trans- 

 verse fold ; elytra at base a little broader than thorax, with the 

 shoulders marked, but rounded, punctured in rather strong and more or 

 less regular rows, which are continued to apex ; the posterior femora 

 are sometimes darker in the middle. L. 2f-3y mm. 



On Malva, Orobus, and J'tcto ; generally distributed throughout England, but 

 more local further north ; Scotland, local, Solway, Forth, Dee, and probably other 

 district* ; Ireland, only recorded from near Belfast, but it most likely occurs in 

 many other places. 



C. ventralis, 111. (aMominalis, Kust. ; iriyrirentrig, Bach.; 

 rentralis, Weise). Ovate, not very convex, testaceous or rufo-testaceous, 

 rather shining, with the breast and abdomen black, elytra lighter than 

 thorax ; head thickly and finely punctured, with a triangular smooth 

 space between antennae, antennae more or less infuscate towards apex ; 

 thorax almost twice as broad as long, with the sides almost straight, 

 finely punctured, with an obsolete transverse impression at base, bounded 

 on each side by a distinct longitudinal impression or fold ; elytra de- 

 pressed on disc, with shoulders marked, plainly broader at base than 

 thorax, punctured finely in regular rows, which become obsolete toward.-* 

 apex which is nearly smooth ; legs testaceous, femora sometimes darker 

 in middle. L. 2-2 mm. 



Chalky and sandy places ; by sweeping herbage ; according to Weise. it occurs on 

 Solamvm dulcamara, but I huvc taken it in the Isle of Wight on Matri<-<iria it 

 pninetiine* occurs in mo*s ; local, but not uncommon where it occurs; St. M:iry 

 Cray, Chatham, Faversham, .Mirkleham, Birdlirook (E**ex), Shirley, Wokinir ; 

 Warlingham ; Shipley, near H or slain ; St. Faith's, Norwich ; Hastings; Saudown, 

 I*le of Wight ; Seaton, Devon ; Llmignllen ( Bretby Wood, Ri-ptmi ; H.ysliam, n Mi- 

 Lancaster ; Ireland, near Waterford (Power). 



This species closely resembles Ochrosis salicariee, from which it may 

 be known at once by the obsolete transverse impression and distinct 

 longitudinal folds at base of thorax; it is also, as a rule, of a lighter 

 than tint insect, and has the elytra longer and more depressed.
