are black, the intermediate ones being red, and the bind legs also red, 

 or with a black ring before the middle. This is Habn's " Abanderung 

 c," under which the description of Schilling is cited verbatim : " an- 

 tennis basi rufis, pedibus pallidis, femoribus anticis nigris." On the 

 contrary, the description of the type of Hahn gives the following 

 characters : " Fiihler schwarzbraun, das erste Grlied derselben am Ende 

 und das zweite am Grande rothlichgelb : die Fiisse rothlichgelb, alle 

 Schenkel, mit Ausnahme der Spitze derselben, schivarz.''* 



Orthotyli, with green cell-nerve and somewhat diaphanous shining 

 elytra. In my remarks on these species (No. 159; vol. xiv, p. 60), 

 some typographical errors are to be corrected. Line 17, from below, 

 p. GO, for "the first joint," read "the third joint ;" p. 61, line 7, from 

 above, for "somewhat sharply," read "not;" and, the same page, line 

 19, for "head," read "third." 



By examining a greater quantity of material, I have reduced the 

 British species to the following : — 



1 (2.). First joint of antennae, beneath, with a black streak. 



O. striicornis, Kirschb. 



2 (1.). First joint of antennae nnicolorons. 



3 (4.). First joint of antennae as long as the head; second joint with some 

 longer exserted very fine hairs, the last two joints together shorter than the second ; 

 third joint a little less (J ) or a little more (?) than twice shorter than the second ; 

 fourth joint as long as the first, and less than twice shorter than the third. Vertex 

 distinctly carinate. The genital segment of the £ scarcely broader than the other, 

 and as long as the five preceding segments together. 5 \ — 5^ mm. 



O. viridinervis, Kirschb. 



4 (3.). First joint of antennae shorter than the head, second joint without ex- 

 serted longer hairs. 



* According to this discrimination, the synonymy will be : — 

 decoratus, Hahn. 



ericetorum, Leth. 

 affinis, Schill. 



decoratus, Aband. b and c, Hahn. 



I had, however, cited (Brit. Hem., p. 183, the Aband. I and c as = adjanctus, D. and S , and I 

 still think so, at any rate, with respect to the former The Aband. b is described : " Das erste und 

 zweite FuhlergliedV«»z und das dritte zur Halfte, nebst den Schenkeln des zweiten und dritten 

 Fusspaares, rothlichgelb," exactly agreeing with adjunctux ; the Aband. c seems to be merely the 

 braehypterous form of b, but in visjw of the appended verbatim description of affinis, that species 

 may be indicated. In any case it is agreed that adjunct as, D. and S., and affinis, Schill, are good 

 distinct species— as species are now reckoned. 



If, as Dr. Reuter says, Hahn's figure 71 cannot be regarded as representing any other species 

 than ericetorum, yet it will have to be admitted that for this both the figure and description are 

 in some points unsatisfactory. Thus, Hahn says that the antenna? are stronger than in S.pictus, 

 and they are so represented ; that the first joint at the end and the second at the base are reddish- 

 yellow, and the figure shows them largely so ; but ha ericetorum the antenna? are not stouter than 

 in pictus, and the light colouring of the first and second joints is pale yellowish (not reddish- 

 yellow), and of very slight extent on either, and, as Dr. Reuter says, the first juint is sometimes 

 ■wholly black. All the thighs are said to be black, except at the apex (the figure does not show 

 the base 1 , but in ericetorum the second and third pairs are longly reddish-yellow at the base, in all 

 the British and foreign examples I have seen. Lastly, Hahn says his decoratus is found under 

 moss at the foot and on the roots of " Fichten und Fohren," which stand at the sides of woods ; 

 whereas, with us, ericetorum is found exclusively among heather (Calluna ', and mostly where no 

 fir-trees grow. — J. W. D.
