1(52 SERRICORNIA. [Dasyteg. 



trochnnters and the base of the posterior tarsi testaceous, the latter often 

 very obscurely so ; the thorax is shining on disc and has no trace of a 

 central furrow, and 1 ho fourth joint of the tarsi is much shorter and 

 narrower than third ; the elytra are somewhat roughly punctured; in the 

 male the head is broader than in the female and the antennae are longer, 

 and the fifth ventral segment of the abdomen is deeply impressed and 

 broadly emarginate at apex ; in the female the fifth joint of the antennae 

 is a little larger than those on each side of it, and joints 7-10 are oblong 

 triangular. L. 4-4^ mm. 



By sweeping herbage and beating hedges, in lanes, woods, Ac. ; rather common 

 and widely distributed in the London, Southern, and Midland districts, and also in 

 Wales ; less common further north ; Northumberland and Durham district, rare ; 

 Scotland, very rare, Solway district, and recorded doubtfully from the Forth 

 district. Mr. Chappell informs me that he has bred it from oak galls from 

 LUngollen. 



D. nig-er, L. Less elongate, and of shorter and broader form than 

 any of the preceding, black, shining, clothed with rather thick and short 

 outstanding black pilose hairs ; head broader in male than in female, and 

 with the antennae longer; in the former sex, however, they only reach a 

 little beyond the base of the thorax; thorax very slightly transverse, a 

 little narrowed in front, especially in the female, broadest behind middle, 

 with the disc more or less thickly punctured, and the sides closely rugose, 

 with a more or less distinct impressed central line in front ; elytra rather 

 closely and finely punctured ; legs black, tarsi elongate. L. 3-4 mm. 



Male with the fifth ventral segment of abdomen moderately, and the 

 sixth rather strongly impressed. 



By sweeping in grnsey places ; very local and not common ; New Forest (where 

 it has been taken by Mr. Champion, myself, and others) ; the species was introduced 

 into our list in 1871 on the authority of Mr. Champion's specimens, but a single 

 specimen was captured by Dr. Power so long ago as July 21, 1855, at the Holt, 

 near Farnham.

This and the succeeding genus contain a few species which are chiefly 

 found in the European region ; two or three, however, occur in North 

 America ; the species belonging to this genus differ from Doliclwsoma in 

 their somewhat thickened tarsi, shorter and stouter antennae, somewhat 

 broader form and pubescent upper surface. 



P. nobilis, 111. (viridis, Eossi). Of a very bright green or greenish- 

 blue colour, sometimes quite blue, rather shining, elongate and parallel- 

 sided, with elytra somewhat depressed, with sparing pubescence and long 

 erect black hairs; head large, thickly and coarsely rugosely-punctate, 

 antennae short, metallic green, feebly serrate ; thorax about as long as 

 broad, with the sides rounded, thickly and rugosely punctured, with a 

 more or less distinct smooth central line or furrow; elytra rather broader
