lateral black points, sometimes anfrujarly prodiicecl in the middle of its lower 

 edj^e but not giving off a well-defined black line. Inner edge of hind tibiuo 

 with a black line reaching nearly to the base. Length 5-6 mm. 



Lives on hazel. Probably common and widely distributed. 



The recognition of these two additional species of Oncopsls will 

 remove the necessity, which otherwise exists, of ascribing to O.flavicollis 

 an extent of variability which it does not in fact possess. 



Continued field-study of the subject shows that we have two species 

 of Mao'opsis living on brambles ; one, which I find commonly at Coles- 

 borne on more or less prostrate brambles growing for the most pai*t in 

 derelict arable fields, for which I appropriate the name ruhi Boh., and 

 the other, occurring everywhere on hedgerow brambles, for which I pro- 

 pose the name scottl. 



Macropsis ruhi Boh. 



Crown rounded or scarcely angular in front. Face somewhat convex, the 

 upper pair of spots rouudish, free, the unpaired marking, usually an irregular 

 sub-rhomboid spot, not, or but little, extending above the lower edge of the 

 upper pair; lorae black at the apex; clypeus without a distinct keel. 

 Scutellum often with a black middle line from the base to the groove. Upper 

 division of the side of prosteriuun black with its upper edge widely pale, the 

 lower divi.^ion unmarked, or rarely with a black point. Dorsal rim of elytra 

 white or whitish. 



Probably of general distribution; Darenth {W. West). It some- 

 times occurs in company with M. scotti ; a simultaneous gathering from 

 roadside brambles in Norfolk consisted of twenty scotti and two ruhi. 



Macropsis scotti, n. sp. 



Ket-embles tlie preceding, but the unpaired marking on the face, a double 

 line, extends well up between the two upper spots, lorae entirely pale ; a more 

 or less distinct dark marking iu the middle of the front edge of the prouotum ; 

 a black middle-line is not developed on the scutellum, even when the two 

 black pointy before the groove are present; dorsal rim of the elytra black or 

 blackish; black marking on the inner edge of the hind tibiae at most only 

 indicated on the basal third. 



Common on hedgerow and bvish brambles. 



Anoscopiis Jtirsclihauini, n. sp. 



cJ . Crown feebly convex throughout; frequently with a bhack inter- 

 ocellar band and middle-line, and an irregular fuscous marking on each side 

 of the base. Pronotum broadly white behind. Elytra brownish-yellow with 

 two macular transverse bauds and the apex white. Barbs of the aedeagua 

 four : two small, curving outward and downward, near the apex ; and two 

 large, which in the cephalad aspect curve outwaid in their basal half and are 

 thence to the apex parallel with the stem ; in the lateral aspect these large 

 barbs have a sigmoid curvature.
