CHIZiOPORA, Kraatz. 



This genus comprises about five European species which have very- 

 much the general appearance of Tachyitsa, but differ from that genus in 

 having the tarsi all distinctly five-jointed : our two species Avere origi- 

 nally associated by Erichson with Galodi'.ra ; they chiefly differ from the 

 species belonging'to that genus in their longer and more slender antennae, 

 of which the second and third joints are of equal length, and the 

 penultimate joints are hardly, if at all, transverse ; they occur in marshy 

 and damp places, chiefly on the banks of streams. 



Upper surface dark, femora and antennaB more or less 



pitchy C. lONaiTAESlS, Tlr. 



Upper surface more or less testaceous or reddish; legs 



and antenna; entirely testaceous C. ettbicunda, JEr. 



C. long-itarsis, Er. Dull black, very finely punctured, and clothed 

 with extremely fine silky pubescence ; head nearly as broad as thorax, 

 antennse long, dark with the base testaceous, second and third joints 

 about equal in length, 4-6 longer than broad, 7-10 about as long as 

 broad in female, slightly transverse in male ; thorax slightly longer 

 than broad, much narrower at base than elytra, with an impression be- 

 fore scutellum that is usually prolonged m a more or less obsolete central 

 furrow ; elytra a little longer than thorax ; hind body parallel until near 

 apex, with segments 2-4 rather strongly impressed horizontally at base, 

 ._very finely punctured or shagreened; legs long, testaceous with femora 

 more or less dusky, posterior tarsi nearly as long as tibiae with first joint 

 not quite as long as the three following. L. 4 mm. 



Male with the ventral plate of seventh segment of hind body much 

 prolonged beyond dorsal plate. 



In marshy places and on the banks of streams; common and widely distributed 

 throughout the country. 



Ci rubicunda, Er. Narrower than the preceding with the elytra 

 distinctly shorter, and also narrower, so that the insect appears more 

 linear and parallel-sided ; the thorax is also more convex, and the pos- 

 terior tarsi are slightly longer and have the first joint a little more elon- 

 gate, about as long as the three following united ; it may, however, be 

 easily distinguished by its colour, which is rufo-testaceous or rufo-piceous 

 with the head and more or less of hind body before apex darker ; the 

 legs and antennae are entirely testaceous. L. 3|-4 mm. 



Male with the ventral plate of seventh segment of hind body less 

 prolonged than in the preceding species. 



On the banks of streams ; rare, but has occurred in some numbers iu one or two 

 localities. Bewdley Forest, sandy banks of Dowles Brook (W. G. Blatch); Clifton, 

 near Manchester (Reston); vScarborough (Lawson) ; Cumberland ; Northumberland
