Very rare in this country, and most often found singly: Svanemose- 

 gaard and at the sound (Schitfdte), Jeels Forest (Rosenberg), Storeklint, 

 ttjfen (Rye); one single time I found it in great numbers in chalky, grav- 

 elly dirt cleaned out of a ditch in Jrejsdalen. It is rather rare in 

 Middle Europe and has seemingly reached its northern boundary in Den- 

 mark. (Page 463) 



A very closely allied species with similar sex-characters is S^ 



rubldus Muls. et Rey. It differs from cognatus by yellowish-red pro- 



notum and longer, more finely punctated, red elytra, and belongs mostly 



in South Europe (Jang lb.). 



3. S. sulcicollis Steph. 



(Steph. 111. Brit. Ent. V, 277; >anglb. Kaf. V. II, 530. - mlnutus 

 Erichs. Sen. Spec. Staph. 606; Kraatz Ins. D. II, 708; Thorns. Skand. Col. 

 II, 208; Muls. et Rey Brevip. 1878, 209). 



Much like cognatus both in form, color and size, but with a little 

 narrower head, which is as long as broad, somewhat more slender antennae, 

 a little longer than pronotum, more finely punctated elytra, and with 

 narrow, not, or only feebly dilated middle-tibiae. Sometimes the elytra 

 are distinctly longer than pronotum (var. intermedins Muls. et Rey); in 

 the typical form as long as pronotum. Most definitely separated from 

 cognatus and the following species by the sex-characteristics of the o , 

 inasmuch as the abdominal sixth ventral joint at tip is with only a tri- 

 angular incision, but without cavities or impressions at bottom. L. 3-3.5 

 mm. 



Very rare here, and found only singly and in few places: Springforbi
