224 THE CANADIAN ENTOMOLOGIST. 



Is found throughout the United States and Canada, but more abund- 

 ant northward and westward of the Carolinas, extending to near the base 

 of the Rocky Mountains. In the south it is replaced by lemniscata, a 

 species closely resembling vittata, but differs in having another white 

 stripe. This species has been tested, and has been found fully equal to 

 vesicatoria as a vesicant. 



8. Epicaitta cinerea Forster. — Black, closely punctured, and clothed 

 with grayish hairs ; beneath clothing dense, upper surface variable. Head 

 sparingly hairy. Thorax densely punctured, sometimes entirely covered 

 with gray hairs, often with a large triangular central space black, divided 

 by a grayish line along the middle. Wing-cases finely punctured, and 

 either entirely grayish or margined with grayish all around. 



Occurs all over the United States east of the Rocky Mountains, and 

 in many parts of Canada. In the Southern States it becomes larger, with 

 the wing-cases entirely gray ; fully equal in strength to vesicatoria. 



9. Cantharis vesicatoria Linn. — Color, above and below, a beautiful 

 shining golden green ; head, thorax and wing-covers closely punctured ; 

 antennae black. 



Found most abundant in Spain, Italy and the south of France • also 

 found in all the temperate parts of Europe, and in the west of Asia. 



10. Cantharis vulnerata Lee. — Body black ; head orange yellow, 

 sometimes with a broad black stripe down the middle ; wing-cases black. 



Extremely abundant throughout the entire Pacific region west of the 

 Sierra Nevadas. Dr. Horn has seen bushels of this insect in some locali- 

 ties literally strewing the ground ; also very common on a species of 

 Baccharis ; he has experimented with them and found them powerfully 

 vesicant, and producing strangury very readily when taken internally in 

 the form of tincture. 



11. Cantharis Nuttalli Say. — Head deep greenish or golden green; 

 antennae black ; thorax golden green with a polished surface, and a few 

 small scattered punctures. Wing-cases golden purple, striped with green. 

 Body beneath green, polished ; thighs purplish, feet black. This large 

 and beautiful insect is extremely abundant in Kansas and Colorado. 



12. Pyrota mylabrina Chev. — Entire body and legs dull ochre yellow. 

 Thorax with two, sometimes four black spots ; wing-covers with three 

 transverse black bands, divided in the middle by the suture, the anterior 

 one being sometimes further divided into four spots ; knees and feet
