13. Very large species 10 ( <? ) to 12 (?) mm. long or even more. Tegidse 



black duhius, Kl. 



— Exceedingly like dubius ; but Avith the body distinctly shorter though 



hardly less broad Average length about 9((J)tolO(9) mm. Tegulce 

 (only in the ? ?) normally red himaculatus, Geoffr. 



14. At least the front pair of legs partly red 15. 



— All the legs black, or at least with no part red 18. 



1.5. All the legs partly red 16. 



— At least the hind-legs black entirely, often only the front pair show any 



red. General length about 9 to 10 mm., bnt small examples occur, one 

 of which (having the tegiilae and a streak on the middle of the abdomen 

 above reddish, probably throiigh immaturity only) is, I believe, the 

 type of scoticus. Cam gessneri, Andre. 



16. Side lobes of mesonotum very shining, their punctures fine and sparse. 



Apices of femora and bases of tibiae red in all the legs. A large 

 polished and impunctate spot at each side of the vertical area (on the 

 tempora). Saw-sheath ? (viewed from above) dilated from base to 

 apex gonager, F . 



— Side lobes of mesonotiuii strongly and pretty closely puncttu-ed all 



over 17 . 



17. Abdomen from the 2nd segment onwards with a distinct transverse acicu- 



lation (rugulose). Cerci black. Coloiir of legs, sculpture of head, and 

 form of saw-sheath as in gonager, of which Konow considered it a 

 variety, but see below " Notes on Species." 'puncUcollis, Thorns. 



— Basal segments of abdomen above polished and very shining. Cerci red. 



Femora often red througliout, but the colour of the legs varies (at 

 least in Continental specimens!) Saw-sheath of ? (n.b.) not dilated, 

 biit slender and nearly parallel-sided throughout (dorsal view). Punc- 

 turation of head strong, but finer and more evenly distributed than in 

 Ijuncticollis liogaster, Thoms. 



18. (7 with dorsal-plates 2 and 3 of abdomen polished and shining (without 



rugulosities and almost impu.nctate), the apical plates being rugulose. 

 Dorsal plate 8 with a central carina, on each side of which is a rovindish 

 smooth impression. Antennae slender, as long as the abdomen... 



ferrugatus, Lep. var. miricolor, Knw. S ■ 



— o S without the above characters, or ? ? 19. 



19. Thorax partly red 20. 



— Thorax entirely black 21 



20. Pronotrun only red, mesonotrmi black. Strongly punctured, biit shining 



with metallic (mostly greenish) i-eflections in certain lights. Length 

 about 10 mm. Antennae rather short hsematodes, Sehr. 



— Mesonotum, as well as pronottun, at least partly red. Head bluish. 



Smaller than hsematodes (about 7^ mm. long) ...sanguinicollis, Kl. ? . 



(N.B. — The g $ both of hmmatodes and sanguinicollis have the thorax 

 entirely black, and so also have the $ 9 of sanguinicollis var. ravus, 

 Zadd., which is far commoner everywhere than the typical form — 

 there is even some doubt whether the latter occurs at all in this 

 country. See the Notes following this Table).
