168 THE ENTOMOLOGIST. 



1. {Podahrus) alpinus, Fk. (1798). Mars. 10. 5 — 7 lines. 

 —Testaceous ; vertex, body beneath, and disk of the thorax 

 black. Very variable. Thorax often immaculate and the 

 elytra black, but the form of the thorax is too characteristic 

 to admit of error. It is a species more abundant in the 

 N. of Europe, being a mountain species in France and Ger- 

 many. In Norway another species is found, T. lappouicus, 

 much smaller and entirely black. 



2. {Ancistromjcha) abclominalis, F. {1799). Mars. 18. 5 — 7 

 lines. — Black ; abdomen testaceous ; elytra dark blue. Fe- 

 male — Thorax red. Varies, with the thorax and anterior legs 

 more or less red. This is the common species of the moun- 

 tains of Central Europe, but does not occur in Sweden, where 

 it is replaced by the violacea, Pk., which will very probably 

 occur in Scotland. It is very like the present species, but 

 has the elytra of a lighter greenish blue, and the legs gene- 

 rally red. 



3. {TelepJionis)fiiscus, L. Mars. 23. — Black ; thorax and 

 margins of abdomen red, the former with a black spot on the 

 anterior margin. This and the next species may be known 

 from all others by their visibly punctured thorax. Less com- 

 mon than the following, but widely distributed throughout 

 Europe. 



4. rusticiis, Fall. (1807). Mars. 24. 5 — 6 lines. — Very 

 like the preceding, but at once known by its red femora and 

 black disk of the thorax. Universally distributed. 



5. obscurus, -L. Mars. 28. 4 — 5 lines. — Black ; thorax 

 and abdomen testaceous at the sides. An insect of N. Eu- 

 rope. "With us found in Scotland only, where it is not rare. 



G. nigricans, Miill. (1764). Mars. 34. 4 — 5 hnes. — Black; 

 head in front, legs and thorax rufo-testaceous ; posterior 

 tibiae and knees black ; thorax rarely unicolorous, but with a 

 black disk varying in extent: when well-developed it ap- 

 pears to form the discoideus, Steph. {nee Abr. 1813) : of this 

 variety I have several examples from Scotland, one with a 

 testaceous dash at the base of the elytra, but I can see no 

 structural difference between them and the more southern 

 forms. Two of my specimens were submitted to M. de Mar- 

 seul, who also returned them as T. nigricans. 



7. pellucidus, F. (1792). Mars. 35. 4^^— 5|- lines.— 

 Black ; forehead, thorax, legs and abdomen red ; posterior
